I a not convinced of the benefits of wearable technology in the immediate future. The watch was the original piece of wearable technology for years, but many people including myself don't bother with them now, because they can check their phone. The other application I can see an advanced version of a heart rate monitor. The fact is these will only appeal to a small part of the population. There are far more people who don't give a shit about their health than do AND want to shell out for something like this.

This article actually gave a new case, for blind people. But considering how frustrating a conventional smartphone can be to get directions (no GPS lock, no signal, the phone has just decided to run slow while you really need it, or it crashes), I am skeptical about how good it will actually be. What is the advantage in having your shoe tell you which way to go over a handheld device like a phone?
