Years ago, various UX gurus touted the coming of the ubiquitous computer– every device would have a computer built in and they would all talk to one another. Mark Weiser coined the term while at Xerox PARC in 1988 and Alan Kay of Apple called this the “Third Paradigm”. It began with mainframe computers (one compute -> many people), followed by the personal computer (one person -> one computer), bringing us to ubiquitous computing (one person -> many computers). Ubiquitous computing can be considered the opposite of virtual reality, rather than surrounding the person within a computer-generated environment, ubiquitous computing surrounds the individual with computers (in between, lies augmented reality). In other words, computers are made to live in our world and not the other way around. Donald Norman updated the term in 1999 and used the term invisible computer and information appliance to refer to the coming revolution of devices that that would have embedded computer chips and effortlessly communicate with one another.

To some degree that has happened, even if you disregard the multiple computers that most people own (desktop, laptop, netbook) even the simple electronic devices that surround us have considerable computing power. According to futurists, my toaster should be talking with my refrigerator to know what kind of bread I have and how I like it toasted or to notify my online grocer that I only had two slices left (some of the early predictions were pretty bizarre and stretched the definition of “usefulness”). But why did their prediction fail to materialize and we’re all living in remedial houses rather than the smarthouse we were promised? Even though my appliances are much smarter than the ones my parents had there is little chatter between my toaster, coffeemaker, or any other smart appliances in my household. Most of the things I own don’t really need to communicate with one another, nor do they have much to say to Net. In fact, most of devices don’t have much to say about anything. My refrigerator still doesn’t know when I’m almost out of orange juice, though, given Tropicana’s new packaging I wish it could tell me what kind I just bought and why it was not the one I wanted. Is ubiquitous computing just one more failed prediction like fifth generation computing (expert systems) or has ubiquitous computing shifting to something else?

Apple takes an interesting two-pronged approach to ubiquitous computing, instead of everything communicating with everything else, the iPhone says – “talk to me, and I’ll talk to those that need to know” and asks “no need for multiple devices, just give me a simple focused task and I can do that.” The latter approach is familiar to everyone who has ever downloaded an app from the iTunes Store, while the former is somewhat new and is made possible by the introduction of OS 3.0 and APIs that allow for easy communication with other devices. The application approach is akin to a universal Turing machine, and the API model is more like a universal interface. It’s not quite two-pronged, rather applications are developed that allow devices to integrate seamlessly with iPhone – I consider it a different enough model as to warrant it’s unique status. For example, Johnson & Johnson made a bit of splash at the Apple developer conference with their demo of LifeScan a tool that integrates a glucose monitor with the iPhone and provides a range of features from simple visualizations of historical data to food tracking to uploading data to your healthcare provider.

Whether or not one believes the hype surrounding LifeScan (is it vaporware or will it see production?), it’s easy to imagine a range of medical devices (or any category of devices) all communicating through the iPhone, all using the iPhone’s screen and its Samsung S5PC100 processor – one person, one user interface with many devices.

I’m not sure if Apple is going to be the one that finally surrounds us with computers or smart devices, but I think their model puts us in more control than the previous one of smart appliances “deciding” for us – when to order OJ, how to toast my bread, etc. My toaster can simply communicate with my iPhone, and I can set how the bread is toasted (silly ideas never really die, they just move around the ether). I think the future is looking less like Terminator Salvation and maybe more like Star Trek [Note: It is very hard to find good science fiction movies or shows that paint a bright picture].
