To begin, think not about the objects, but about our desires. We want to know it all—but not all of the time. Sometimes, we just want to know whether it’s cold outside, or whether the dog has been fed. We don’t know the details, don’t really need to know the precise temperature or the moment in time when the dog’s bowl was filled with food. So instead of a thermometer, or, more intensely, a digital thermometer that reports temperature to the tenth of a degree, how about a glowing orb? Or, as author-scientist-innovator-professor David Rose describes his invention, an Ambient Orb. He writes, in his new-ish book, Enchanted Objects, “They aren’t disruptive. They have a calm presence. They don’t require you to do anything…They are there, in every room of the house with the exact information you expect from them.” So he reimagined a crystal ball that contains LEDs that change color, and report the information you need by glowing in your choice of hues. “As the colors change, you glance and know if the pollen count in the air is higher than usual.”

Why not a jacket that hugs the wearer every time she receives a “like” on her Facebook page? (This, from one of David’s students.) Or a toothbrush that knows it is being used (and being used properly), and recognizes your good work, rewarding you with a discount at the dentist? (Oy. The gamification of dentistry! Nah, not in David’s hands. He’s smarter than that—check this out.) One of his entrepreneurial firms was hired by a big pharmaceutical firm to bring some life to the little plastic pill containers. Hoping to change the behavior of the the many patients who do not take our prescribed meds, David’s company, Vitality, changed the cap. The cap glows when you’re supposed to take a pill. Even better, the GlowCap texts you when you’ve forgotten to take a pill, and automatically sends refill messages your local pharmacy. The “adherence rate” is up to 94 percent, far better than the 71 percent achieved by a standard (boring, non-glowing, non-internet connected) vial. It’s information at a glance, again non-disruptive.

David’s vision of the future: whatever the device may do, it must be affordable, indestructible, easily used, and, when it makes sense, wearable. Lovable, too—his clever illustration of interactive medicine packaging are based upon faces that transform themselves. They’re happy when you’re doing the right thing, grumpy if you’re not.

I love the idea of a Conversation Portal, an expansion of the telepresence office conferencing systems that allow people in different physical places to sit at the same half-digital, half-physical conference table. It uses large screens to display flat versions of real people’s bodies so that they feel as though they’re in the room. The Conversation Portal places that concept, more or less, into an informal lunch table setting. Virtual workers—perhaps five percent of the workforce, with more to come—can enjoy human interaction during a morning coffee break.

I also like the idea of a smart bus stop. It’s a digital sign that tells you how long you will have to wait for a bus to arrive. By connecting to the bus system’s GPS system, it provides a convenient visual answer to the inevitable question, “when is the bus going to show up?” His research found that “by eliminating the uncertainty of when the bus will arrive, people become more patient—and they don’t give up on the system i if the wait is longer than fifteen minutes…This enchanted system changes the perception—and behavior—of an entire city of riders.” (In this case, San Francisco.)

David dreams of on-demand objects, and objects that learn and respond to personal needs. Vending machines, for example, that customize their offerings based upon “a prediction of what the person will like.” He envisions “digital shadows” for objects—information associated with physical objects enhanced by digital projection.

For those who intrigued by technology, but don’t want to dig into the technical details, David has written a marvelous, positive book about a future that he is actively creating with his colleagues. Nice to get a first person account, nicer still to be in the presence of someone with such boundless enthusiasm (and smarts).
