Yesterday, at Google’s I/O developer conference, Sergey Brin rocked the socks off the audience by walking on stage with the forthcoming Google Glasses, connecting to a group of skydivers also wearing them, projecting the video streaming from their glasses as they fell, until they finally landed on the roof of the conference center. Unbelievable.

The device, he announced, would ship early to developers beginning next year.

I’ve been obsessed with the glasses since they were first announced, and have tried to predict how they might work (with some success). Today, I want to explore how they might fit into health.

The easy part is that most anything you can do with mobile in general, you can probably do with Google Glasses. So medication reminders, tracking data about movement and communication, that’s easy.

But I think it gets crazier. Imagine if apps like Laveem get sophisticated enough that you could look at a food item (or maybe more realistically a food item’s bar code in the supermarket) and see roughly how bad that item was for you right in your field of vision?

Take it one step further, and consider how the glasses might then be utilized as a motivational tool. Have you ever played around with one of these programs? Apps like Fat Face Booth let you humorously visualize how you’d look with an extra 50+ lbs. Imagine a picture of yourself from Fat Face Booth pops up every time you look at a McDonalds menu. 

Or, if you think that’s too cruel, have it cue a picture of yourself from the beach last year after those three months where you actually stuck to your exercise regime and got in shape.

And if this sounds torturous, it need not be. With integration between the glasses and both fitness and mobile payments apps, it’d be easy to know when you deserve a slice of cake or some fast food vs. when you’re spiraling into a diet wrecking binge.

One of the beautiful things about this is that it puts the burden with the consumer. Rather than mandating that businesses provide calorie counts next to every item in a restaurant, the individual could tailor a personalized information and motivation system in his or her own field of vision.

Some people appreciate a little friendly pressure every meal to stick to their diet; others want to live and let live. The beauty of the mobile “good behavior layer” is that we don’t have to settle for a one size fits all solution.
