GeoClock: Ambient World Clock (Physical Device)
Here's an idea for a physical device that's "on the shelf". From January 2007.
One of the partners had a really neat looking world map hanging on the wall of his office. Later, I found out it was a GeoChron, a special kind of world map that displays the time, anywhere in the world, at a glance. It also shows you where it's dark and where it's light (the declination of the sun)
The GeoChron is a really interesting device. It's completely mechanical (not digital), hand made, and is rather expensive (prices range from $1,700 to $3,000). Here's more information, directly from the manufacturer:
The Geochron is the only instrument of its kind to simultaneously exhibit the current time anywhere in the world as well as displaying where the sun is rising, and when it will set. Each gear is individually hand-cut to ensure optimum synchronization. Each world map is made using state of the art lithography printing which uses specially formulated inks designed to make the map resistant to ultraviolet light.
Fast forward to January 2007. Digital picture frames were a big consumer craze. These were $100 to $200 devices that would sit on your desk and show you a slideshow of photos.
I thought there might be an opportunity to create modern version of a GeoChron, one that would be perfect as an executive gift or desktop accessory. I called it GeoClock.

| My "GeoClock" design. It says "ambient" in the top-right corner because I pitched the device to David Rose, CEO of Ambient Devices. David had experience designing, manufacturing, and distributing hardware devices at retail stores. I sent him a "prototype" which was an off-the-shelf digital picture frame with a number of still images in sequence, "faking" what the real product would look like. |
I figured I could sell this thing for $200 to $300 dollars. I didn't know much about the hardware costs, but I assumed that the components were very similar to the digital picture frames: a display, some kind of processor, some memory. And of course, some custom-developed software that would render a picture of the earth, draw the declination of the sun, refresh the display every x seconds, etc.
Here are some additional thoughts that I captured in a short presentation:
GeoClock Overview
Has the time for a product like this passed? It seems like digital picture frames came and went. I assume it's because 1) they're rather wasteful (always on, drawing power) and 2) the image they produce fades and degrades over time.
Clearly this would make a great app for Android, iPhone, iPad. A quick search in the Apple App Store lists a number of them with similar features.
RocketMenu: Unobtrusive Search and Reference Tool
This is the second post in a series where I revisit an old idea that is "sitting on the shelf." This idea is from November 2005.
Remember 1-Click Answers (Formerly "Gurunet" and "Atomica")? Babylon Translator? These tools (from back in 2005) were great because they provided useful reference information on-the-fly. For instance, with 1-Click Answers, you could highlight a word in any application (on the web, within Microsoft Word, etc.), and get a definition, synonyms, antonyms, etc.
With Babylon, you could highlight a word and get an instant translation in a number of languages. Babylon was especially cool (from a technical point of view, anyway) because it used OCR-like technology and even worked with images (not just plain text). That is, you could get an instant translation of a word that was inside an image. Pretty nifty.
I came up with RocketMenu - a more flexible search and reference tool:
- Users select any word or phrase with their mouse.
- A small icon appears beside their selection.
- Moving the mouse over the selection displays search, dictionary, thesaurus, and other results customizable by the end-user. Unobtrusive text-based advertisements appear beside the results.
- Should the end-user click on one of these advertisements, both RocketMenu and the Site Operator (from where the original word or phrase was selected) receive a small portion of the advertising revenue.
Here's an early design:
 |
| Here, I just stuck Google Adsense to the right of the menu. |
Later, I improved upon the model by removing most of the advertising and instead relying instead on affiliate revenue (that is, many of the links, when clicked, would generate revenue to RocketMenu). I also made the menu items context-aware. Items would become bold if the search term matches a pre-defined context.
In the following example, the search term is "www.selectsense.com" and the menu items "WhoIs", "Web Archive," etc. have all been set to become bold when the input is a web address (ends in ".com" or ".net", etc.)
RocketMenu was designed to be a desktop app (like 1-Click Answers and Babylon). Additionally, web site operators could "embed" RocketMenu into their web sites, and, in doing so, we would share our revenues with them.
The idea is that every word or phrase on the computer screen becomes a vector for:
- more information (for users)
- additional revenue (for web site operators)
I envisioned a home page with a very direct call-to-action ("Download RocketMenu Now").
My pitch to web publishers was centered around easily earning additional revenue. Further, I was trying to run with the idea that web publishers were inspiring lots of revenue-generating searches on Google, Yahoo, and other leading search engines.
Meaning, you read about something on some web site, then you jump over to Google and search for something related to what you just read. Chances are, Google monetized that search you just did. The web site that inspired your search earned nothing.
Here is a more complete set of wireframes, if you're interested. You'll see that I was using a mix of Visio and pencil & paper for my wireframes and mockups at the time (now I use Balsamiq Mockups almost exclusively).
RocketMenu Version 1 Wireframes
Over time, a number of companies have emerged with similar products. Among them are Vibrant Media, Hyperwords, Apture, Wordclick, and I'm sure many others (I haven't taken a look in many years). UPDATE: Check out Highlighter - they have a really interesting approach.
This is one of those projects that I abandoned simply because I got busy with other work. There might still be something here, although I am sure many details would have to change. Maybe a web browser extension or plug-in? (see Polaris Insights Chrome Extension for a utility that displays info about [mostly startup] web sites). Maybe a tool that is completely context-sensitive (that is, only relevant menu items are displayed)? Maybe something like this for mobile devices (iPhone, iPad, Android)?
I'd love to hear any ideas that you might have.
Firestorm: Preserving and Sharing Old Photographs
This is the first post in a series where I revisit an old idea that is "sitting on the shelf." This idea is from October 2003.
It was October 2003, and Southern California was burning. I was sitting at home with my soon-to-be mother-in-law and we were watching the news. All of the news stations were covering the situation with panic: "Firestorm 2003"!
(Note: Thankfully this isn't me. Just a representative video I found on YouTube)
The news teams interviewed a number of folks whose home had been lost. They were devastated:
"What am I going to do!? I lost everything. My photos. My memories. "
Here are my first thoughts about a solution (from October 2003):
If you only have a few moments before your home is engulfed in flames, what possessions will you spare from destruction?
Family Photos? Videos? Other physical keepsakes? This is what everybody says! In this day and age, I find this response almost ridiculous!
These possessions are often considered "priceless." How much would the average upper-middle-class family pay as an insurance policy against the destruction of these possessions? $5,000? $10,000?
It could have some very interesting business potential.
These items could be processed in a lab that would:
- archive the images as digital images (say, with scanners)
- archive drawings / paintings / physical objects as digital images (say, with cameras)
- archive the video as digital videos (with analog to digital duplication equipment)
- store the data in natural-disaster and fault-tolerant data centers.
- make this data available on the internet to other, extended-family members (viral marketing!)
- give the customer two copies of everything on DVD: one copy for home, another copy for the safe-deposit box.
People could:
- drop off these memories at a local store (kinko's model)
- ship these memories to a processing center ("warranty" service model)
- have a processing-van (think huge logo, local branding) come to their home to do the work on-site (van model)
The approach largely depends on how much "distance" from "memories" becomes uncomfortable (for the average customer). Fears could be augmented with strict handling procedures, strict storage procedures, and nationwide branding. Lot's of possibilities here.
Model:
- Charge customers variable cost (in cents) per item. Outdated video formats would command higher prices. (All costs relative to costs of processing equipment and labor).
- It will be impossible for customers to sort their items: they cannot possibly filter their memories by level of importance! They will have to give us everything...
- Customers can come-in with boxes and boxes of items, unsorted, unorganized. We do the work, give them 2 copies of DVD's, other deliverables.
- How much could the one-time infrastructure costs (per processing center) possibly be? $250k? How many families in suburban communities (like Agoura, Westlake, Thousand Oaks, which has over 15k married dual-parent families with kids). Recurring revenue might be a serious problem. Do digital/analog photo development and other ancillary services? Ahh! Instantly add these newly developed photos to the "archive"...
Like online tutoring services, we would be pleading to emotions: is it really worth risking the loss of your memories? Don't you want to guarantee these possessions for your children, and future generations? ....your parents? ...your children? Threat of fires, floods, tornado's, earthquakes, hurricanes, theft, loss?
What feeling is more innate than the desire to preserve thoughts, memories, emotions? Everybody feels that their life is important. Everybody wants to leave their mark on the world. It is a human motivation as innate as survival and procreation, and ties hand-in-hand with both.
So I got busy (co-founded Academy123) and "parked" the idea. A few years later, I started thinking about it again: putting together an overview, thinking about the workflow, and mocking-up would-be marketing materials.
I proceeded with the assumption that people wouldn't want to part with their photos (I needed to create as little distance as possible between a person and their photos). So, the solution would be to go to their home, with a van, just like a carpet cleaning service.
I ran into a technical challenge: how do I quickly scan all those photos? Varying shapes and sizes. Some in albums. Some stacked in shoeboxes. Basically, I had to assume a huge mess.
My first breakthrough was to think of a "good enough" solution: why not just take a photo of a photo? I could automate the process of capturing the image, cropping it, de-skewing it, etc. In a Ford Econoline van (or similar):
- Setup a conveyor belt.
- Have an operator just slap down photos on the conveyor belt, not paying much attention to placement. Can even place entire album pages.
- At the end of the conveyor belt is a "black box" where the photo enters. Facing down from the top of the black box is a high-resolution camera. Basically, something in the spirit of this Bookscanner developed by Xerox PARC.
- The camera just snaps a photo (of the photo!) at regular intervals
- Later, software (like imagemagick) cleans up the photos: crop, de-skew, separate multiple photos that appear on one album page, etc.
Later, I realized that companies like Fujitsu make some really high-speed and high-quality scanners. I actually got a hold of a Fujitsu unit, ran some initial tests (scanned a bunch of photos, cleaned them up in an automated way, etc.). This unit has a large auto-feeder (photos) and also a flatbed (album pages?). The scanner is incredible. It basically scans photos just as quickly as a high-speed printer can print color pages. It can do about 60 photos per minute. And, you could just stack the photos any-which-way.
So, I ran with the concept and started fleshing it out a bit:
Firestorm Background
Here, I mocked-up a flyer that would describe the service to a consumer. I toyed with the idea of snail-mailing it out to 1,000 households to see the response andgaugedemand (these days, web developers do the same thing by designing a landing page and buying some Google Adwords).
Firestorm - Draft Flyer
I continue to be very much in love with the idea in that I think the need still exists. I think affluent families would pay a one-time service fee of $500 (or similar) to preserve their old photos forever. I think the business could scale just like any typical "franchise" type business (not very interesting when you're accustomed to working on web companies that can scale worldwide with a tiny staff).
Clearly, photos have moved to digital. Successful photo-sharing sites have proven that photos are extremely viral in nature, and I think that these old photos are not an exception. As evidenced by many of the same photo sharing sites, there are a number of ways to monetize the photos long-term: subscription service for storing and backing up, ordering prints, ordering archive dvd's, printed photo products, etc.
I think there might be a short term (10 years?) window of opportunity to "grab" the worlds old photos and bring the old, printed, analog photos to digital. The company that can do this can monetize those photos (and the online viewers of those photos) for many years to come.
Ultimately, I abandoned the idea because it's just not scalable (in the typical sense as described by web developers).
I know that there are a handful of companies out there doing something similar. Digital Pickle has been around for a while, but you have to mail your photos to them (non-starter for mass-market, in my opinion). Kodak had a short-lived ScanVan initiative where they brought photo-scanning trucks to local shopping malls, and I'm not sure what happened there.
The Biggest Problem With Software Development
In my opinion the number one biggest problem with software development is that programmers concern themselves WAY TOO MUCH with the implementation; when, in fact their "stated" goal is to solve a particular problem. As such, the implementation technology is not important; whether it be software, pen & paper, mechanical, whatever.
The REAL goal is to come up with the most efficient solution to a general problem.
First and foremost, in order to solve a problem, a person needs to have a very detailed understanding of the problem. This step is often overlooked.
Programmers love to program. Tell a programmer about an idea you have about a product (say, a better way to manage the workflow of a lawyer) and before you've finished your first sentence, he will already be coding away in his head.
Not only is this way of working ignorant, but it is extremely arrogant. (using the above example, how in the world could a programmer know enough
about the lawyer profession to write a program that runs a lawyer's entire business, after say, only conducting a few days of background research?)
Most programmers are not driven to solve the abstract, general PROBLEM, but are driven to wrangle the complexity of the computer, solving the complex bugs introduced in the process, and managing the other endless minutia.
I think Computer Science should look towards other, more established professions like Architecture. I haven't done much research on the subject, but I know that Architects spend a LARGE proportion of their project developing the blueprints, working out the fine details, getting them to pass endless codes (fire code, safety code, etc.). ONLY THEN, once the blueprints have been hammered, does construction begin. THEN, even after all that, the construction process is a difficult enough profession that workers will have interesting problems to work out! (similarly, Programmers can't cry and say "hey - that's what we're for!" Believe me, there is a lot of detailed, cryptic, hard work to do EVEN IF a programmer is handed excellent Product Specifications).
Conflict in HCI Field: Computer Science vs. Psychology
Recently, I have become obsessed with what I feel is a huge conflict in the HCI field between the role of Computer Science and the role of Psychology. Most HCI courses, programs, or research I run into involve coming up with newer, novel, and more "effective" software strategies. Usability Tests are conducted in order to test the effectiveness of one particular strategy vs. another (Example, Browser-based interface vs. Native Windows Interface).
Although these things are important, I feel that the REAL issue at hand is largely being ignored. THE BOTTOM LINE: The purpose of technology is to make life easier. More specifically, to simplify a particular task or set of tasks.
As such, software is not very interesting. It is merely a tool for accomplishing the goal; a tool for IMPLEMENTING the goal. What's more, history has shown as that the tools we use for accomplishing our goals constantly change, and of course, they will continue to do so.
So, what is REALLY interesting, and what is REALLY important, is discovering (or should I say, "working towards") the IDEAL way to accomplish our goals. FORGET ABOUT THE IMPLEMENTATION! It is absolutely SECONDARY! It should be of no interest to us; what's more, we should make a conscious effort to completely block it, and it's inherent set of limitations, out of our mind.
Only later, after we have meticulously (and with solid engineering methodology) beaten the hell out of our IDEAL solution, and tested it using all known human ways and means, should we even think about adapting our IDEAL solution to the constraints of the implementation (which, in our case, is usually software).
SO, exactly HERE is where I see the conflict between Computer Science and Psychology in the field of HCI.
Computer Science focuses way, way, way too much on the implementation!
Computer Science students who take HCI courses, or even Computer Science PROFESSORS who teach HCI courses, LIVE in the world of software. Their brains are immersed in the idea of software. When they are asked to develop a program, they start off in the world of software and try to make their way into ADAPTING the WORK DOMAIN (the set of tasks they are trying to simplify or automate) INTO their world of SOFTWARE.
Psychology students and professors work precisely in the opposite direction. Their brains are immersed in the idea of understanding human behavior and thoughts. As such, they start off with a solid conceptual model of the WORK DOMAIN, and try to make their way into the world of SOFTWARE.
So, in brief:
Computer Science moves from Software --> Work Domain.
Psychology moves from Work Domain --> Software.
Clearly, the field of Psychology takes the correct and logical approach, while the field of Computer Science does not. The fact that poor requirements analysis is the primary reason why most software projects FAIL, serves to prove this point.
HCI is unfairly weighted into the realm of Computer Science. Instead, it should be leaning more towards the world of Psychology.
Computer Science students do not know what HCI really means. Their curriculum and professors push them towards the process of "coding." The ongoing "crisis" of consistent failures in the software industry will continue until computer science professionals stop thinking, myopically, in terms of software all of the time.
What we need are Software Engineers, whose first and foremost goals and obligations are to understand the dynamics of the work domain.
Secondly (and less importantly) they must know enough about the different implementation strategies in this world in order to make good decisions.
Idea: Questionable Sales Tactic
Given a person's first, last, or first & last name as an input, spit out the "likelihood" of the origin of their name.
EXAMPLE:
INPUT:
Name: Ginter Trybus
OUTPUT:
German - 64%
Austrian - 28%
Russian - 5%
Swedish - 2%
Other - 1%
Could be very useful for salespeople, for which finding an intimate connection with a sales prospect could spark a meaningful conversation, which, in turn, could result in closing a sale.
It would be a good idea to research the most important or most useful "things" to know about a person (either explicit or general) in order to close a sale.
Possibly a way to learn more would be to sit and listen to a salesperson at work, and actively monitor his discussion with the prospects. What things does he say? How do the things he says affect the conversation? Focus, specifically, on those conversations that lead to the closing of a sale. What happened in these cases?
These other "things" could be implemented separately, so, what you would get, in the end, is a set of tools that would allow you to GUESS some DETAILED information about a person given some GENERAL information about them, such as name, age, sex, etc.
These tools could run in real time as the general information is inputted, and those results that are most relevant could be displayed, for example, as a sidebar on the screen.
SO, for example, a potential customer phones a company, say, ACME, Inc. for information about ACME's new product. The salesperson offers to send the customer marketing materials for the product. The customer accepts the offer, and the salesperson records the name and address of the customer, "Nima Bakhtiary", 1234 Anywhere St., etc.
CASUALLY, the salesperson says, "Ahh, that is an interesting name. Does it happen to be Iranian?"
Customer says, "well actually, it is."
Salesperson says "I thought so, [INSERT BULL%&*#, such as: 'a former colleague of mine was Iranian - a real great guy, he's one of the most brilliant people I worked with. .. .']
ETHICS: QUESTIONABLE
IF IT CLOSES MORE SALES: (most people would say:) WHO CARES.
ASSUMING that such a suggestion is not offensive (which may be, for example if you ask a Greek person if his name is Turkish, or, if you ask an Israeli if his name is Palestinian), then this could lead to a useful discussion (in terms of creating a relationship and closing a sale).
Jupiter Communications: "Interactive" and "Rich" Web Interfaces
Jupiter Communications recently issued a press release discussing the need for more “Interactive” and “Rich” web interfaces:
http://www.jup.com/company/pressrelease.jsp?doc=pr000907
I definitely agree with their general statement, however, current technologies (Java, Flash, etc.) are geared more as a replacement to the commonplace HTML interface; as such, they introduce (an entirely new and non-standard) interface and navigation paradigm which by nature counteracts any potential increase in usability. These new interfaces create a steep learning curve – which is completely unacceptable on the web. Users will simply choose a site they are more comfortable with.
Also, it should be noted that the Jupiter press release explains that users demand a more interactive interface. Users say they would use features such as zooming and virtual dressing rooms. Jupiter is asking users to make decisions as to how they would like a site to be implemented – which I believe is the wrong approach. It should be the role of the designers to decide how a site should be implemented – and the designers should make this decision based on learning as much as humanly possible about what the users want to get done.
Jupiter’s approach is equivalent to some average Joe telling an architect EXACTLY how he would like his house designed – Tile floors that are heated 24 hours a day, A living room with a TV that is built into the wall, and a bedroom with a 100 foot high ceiling that has a pool above it. This average Joe is DEFINITELY not in the position to make these detailed design decisions, as he has absolutely no idea about the underlying technicalities: heating the tiles would cost a tremendous amount of money and may cause the tiles to crack, building the TV into the wall would make it an absolute pain to replace the TV or add/remove devices such as VCR’s, and a 100 foot high ceiling could only support pool with the use of huge steel beams in the center of the bedroom.
Jupiter’s press release should not serve as a literal explanation of what needs to be done, but as an indicator that users are unhappy and want an interface that better satisfies their needs. HOW that interface should be developed should be decided by designers who focus on what the users want to get done.
Short Analysis: Online Tutoring
I feel that online tutoring idea has HUGE potential and that it is an untapped market, although I still have some problems with the idea. I’ve been thinking about the advantages/disadvantages of online tutoring vs. real-life tutoring...
ADVANTAGE: The online tutoring idea allows for a lower transaction cost (figuratively, not literally) than real-life tutoring.
It would be much “easier” to go online for tutoring. People would not actually have to get up and go to a physical location. But, the main advantage I see here is the social aspect. Many people have a hard time meeting others and communicating. People use external devices to help them feel more secure about themselves. Bars (alcohol) and online chat rooms (anonymity) are testament to this fact. I think, in many cases, a person’s insecurities hold them back from using real-life tutoring. Many people who need or are told that they need tutoring are already insecure about themselves to begin with! They may feel “dumb,” “slow,” what have you...
The fact that online-tutoring is much more anonymous is a huge advantage.
DISADVANTAGE: Person to Person communication with people is VERY limited online.
Currently, our technology limits us to very simple means of communication: text, images, virtual “whiteboards,” etc. The richer means of communication are waiting on the heels of technology. In real-life, person to person communication is MUCH richer. Obviously, being tutored step-by-step through a complicated calculus problem would be MUCH easier in real life: hand gestures, voice (tone of voice IMPORTANT), free-hand writing (look at the math newsgroups to see how, using the limited characters (tools) they have, they express math problems).
This online-tutoring idea NEEDS to leverage the value of the network. I don’t see how this will be achieved. One idea is to have a LIMITED BACK-END POOL of people. These people will be the paid “tutors,” helping out the students. This limitation exists in real-life as well. If I want to be tutored at UCLA, I’m limited to those UCLA students who choose to be tutors. Now, of course we’re talking the Internet, and the LIMITED BACK-END POOL can be MUCH BIGGER (thousands of people from all over the world) and it can be MUCH MORE DIVERSE, but this limitation still exists. Ideally, this LIMITED BACK-END POOL would grow in proportion with demand for tutoring.
The biggest challenge I see in all of this, which, in my opinion, should be the FUNDAMENTAL advantage of online-tutoring is the “matching up” of problems and solutions. Ideally, if you have a problem, or need help with something, you would be helped instantly by an expert in the topic whom you can easily communicate with. So, let’s assume we have a diverse BACK-END POOL of people. A student has a problem. How do we determine who the most “qualified” tutor is for a student? What if a student is matched up with someone whom with they just can’t learn? What if another tutor is just plain and simply more “qualified” than a tutor that is currently serving a student? These problems exist in real-life, however they would be even bigger online. Online, the tutors would have much less knowledge of each other and each other's skills (unlike, for example, in a real-life tutoring center where the tutors can interact and communicate on a daily basis, and learn who is best suited for each task).
One idea would be to make the tutoring effort more collaborative, not simply a 1 to 1 ratio between students and tutors. Let’s assume a student has a difficult geometry problem. He “posts” in a public, globally viewable place, his problem. Immediately, he is helped by the most qualified person. Tutors, having the ability to view “pending” problems they are interested in, can “join-in” the tutoring effort, and provide help if it is necessary.
Now, this idea clashes with the LIMITED BACK-END POOL model. However, maybe we can remove the LIMIT on the BACK-END by allowing anyone in the world to instantly become a “tutor.” We could have “CERTIFIED” tutors (who are PAID for their work), and then just “CONTRIBUTORS” (who work on free will).
This idea would be REALLY harness the power of the Internet. Like newsgroups, there would be absolutely NO LIMIT on the BACK-END. However, unlike newsgroups, it could be organized, moderated, and real-time. Now thinking about it, I used to see it (and be part of it) on America Online (back in the days..)! AOL has a chat area where members can go if they have problems/questions. Each chat room is run/partially-moderated by a PAID AOL support staff member. AOL Members who join the chat room wait “in line” to be served by the AOL staff members. Because AOL was not capable, in certain situations, to support all of its members, some chat rooms did not have AOL support staff members. As a result, smart, experienced members would help each other.
Now thinking about this, I have a model in my head how this could all be put together. I see a web server primarily used to display “pending” problems (that students have). This information would be categorized, by subject, and of course, searchable. All “tutoring” could be done peer-to-peer, meaning that no real-load would be put on a SERVER (very decentralized). The real question is the environment in which the student and tutor will communicate. Ideally, they could use any internet-capable appliance in the world to communicate, so having the application non web-based (like ICQ) would not be good. However, making the application web-based would pose some real limitations as far as expandability. Maybe a Java app would be an option. Whatever model it is developed on, it should inherently lend itself to change in communications technology (video, voice, etc).
Short Analysis: Wireless Data Access
Market Status
Much utility could be gained from allowing all types of information and services to be accessible via wireless devices; the same type of information that is accessible via the web, for example: corporate data, banking, stocks, flight info, e-mail, news, calendar, maps/directions, instant messaging, multiplayer games, etc.
When talking about Wireless Devices, we're really talking about a wide range of tools: cell-phones (Nokia, Motorola, etc.), PDA's (Palm, WinCE, Psion, etc.), and Pagers.
Cell-Phones
Currently, cell-phones have very limited data bandwidth, practical only for text-based communication. Richer multimedia is waiting on the heels of "3G," the third-generation high-speed network. The majority of cell-phone innovation is taking place in Europe, where a very high percentage of most populations have one.
The two most prominent platforms for data communication on cell-pones are SMS (simple message service) and WAP (wireless application protocol). SMS allows for only very rudimentary communication; it only allows for short text messages to be sent from one SMS device to another. WAP, however, is a complete operating environment for wireless applications. Ideally, a person could browse the web on their cell-phone with a standard HTML-based browser. However, because of the fact that a cell-phone's user interface (the very small screen, the limited data input capabilities, etc.) is so drastically different from a desktop PC, WAP emerged.
WAP relies on WML (Wireless Markup Language) which is an implementation of the XML standardized specifically for use on wireless devices. WML is very similar to HTML, as they are both markup languages, however they have slight differences to accommodate for the cell-phone's limited interface: WML uses a "Card Metaphor," where user interactions and navigations are split into "cards" (think "page"). A collection of cards are called a "deck" (think "site"). WML also makes use of WMLScript, a scripting language derived from JavaScript. WAP also includes an API for telephony operations (make calls, etc.) and utilizes standard formats for Business Cards, Calendar, Images, etc.
More information regarding the WAP standard can be found at: http://www1.wapforum.org/member/developers/slides/wap-application-environment/sld001.htm (details of WML comes in at about slide # 11)
PDA's
This market consists of two different types of machines: PC Accessories (extension of the PC; like Palm, Visor, etc.) and Handheld PC's (roughly PC-equivalent, like most Windows CE machines; Cassiopia, Velo, Psion, etc.).
Wireless communications for these PDA's include the Palm VII with its built in modem and data service, and various wireless modems for the Palm III, Palm V, and WinCE devices.
Pagers
One-way communication on paging devices has been around for quite some time, however, new paging devices are allowing two way information.
Problems
Here are a list of just some problems with these wireless data devices (of which successful companies will solve):
Privacy - Privacy becomes an increasingly bigger problem as, via these products, people and data will become more and more accessible. Time management becomes even a bigger issue than it has previously been, as people will struggle balancing work and home life. Some people claim ubiquitous access will allow them to work more efficiently, therefore creating more free time. Others feel that it will allow work to encumber upon home life, driving up work expectations to get things done quickly.
Software Usability - like HTML, user interaction with these devices are not in real-time, and are therefore very poor. Also, data input with these devices are very poor, and are limited to using tiny keyboards, on-screen keyboards, numeric keypads, and special pen-based languages. Voice input and "Predictive Text Input" (where a dictionary tries to guess and complete the word a person is keying-in) are steps in solving the problem. Many feel that voice-input naturally lends itself to wireless devices, voice being the inherent unbound communication tool for humans.
Software Portability - HTML introduced a very simple way to distribute applications, where a client device (a PC) simply "accesses" and uses software located on the server. These wireless devices are following the same trend, however, the differences in these client devices (Phone, PDA, wristwatch) are far more extreme. Tools that allow developers to easily port software efforts from one platform to another platform are essential.
Data Portability - Before having access to the network, most wireless devices "synchronized" with software in order to maintain data integrity. This was due to the fact that there were two or more software packages (usually from different vendors with dissimilar interfaces) each with its own way of storing its data. As applications become more "portable" (as described above) the need for multiple software packages with multiple data stores will decrease. Data will be stored on one server and will be "accessed" by a myriad of different devices. (See "Server Side Data and Networked Clients").

Web Browser as an OS; SAP client as a web "site"?
The navigation of a web browser (URL line, back, forward, hyperlinks, bookmarks, etc.) allows a user to access a particular web page on a particular logical "site." This navigation is built-in to the web browser and, for the most part, cannot be changed; it is constant.
Every site employs its own means of navigating within the site. For example, many sites list "site categories" on the left side, such as "Products," "Support," etc. This means of navigation varies from site to site; it is dynamic.
Looking at a web browser and a "site" in this respect, is a web browser not unlike an Operating System? Is a "site" not unlike an application?
Windows 95 is an operating system. It provides the environment in which Windows-based apps "live." A web browser provides the environment in which Web-based apps live.
Now, there are huge differences between the environment that Windows 95 provides, and the environment that a web-browser provides. Windows 95 allows for much richer human-computer interaction. Applications written for a Windows 95 environment can respond to user actions in (from the user's perspective) real time. Web-based applications inherently require the user to "submit" information, which is processed by a server, which is then responded to by the server. Windows-based apps can display a "grid" on the screen that can be sorted by clicking on a particular column. Web-based applications require a page to be completely re-loaded every time a list of items is sorted. Windows-based apps can support dragging & dropping of information… . etc. etc..
Over time, it seems that the Web browsers are, however, becoming a more interactive environment. Client-side JavaScript, client-side VB-script, and Java applets are testament to this fact. If this trend continues then Web Browsers will provide an environment increasingly similar to the environment that Windows 95 provides. Dragging and dropping, "live" interaction, etc. will be made possible.
This raises a bunch of questions:
- How will this more-interactive environment be made possible? Will HTML embrace all kinds of "smarter" controls, like "Grids," and become a GUI development environment, like Visual Basic?
- Will technologies like JAVA beat-out HTML because of their inherent interactive-ness? (while still providing the web's server-centric advantages).
- More and more applications are being developed for the web. Once standard client/server Windows-based apps are being made accessible by a web browser. Is a web browser's navigation paradigm (back, forward, hyperlink's, etc.) suitable for these apps? (for example, let's say an accounting package). Wasn't the Web Browser's navigation paradigm designed for navigating through hypertext (just text and links)?
