I'm not sure that's the purpose. I wouldn't think of this as being intended to be a fully usable product right now. They could be intending it merely as an interesting experiment to explore new possibilities for interaction with mobile and wearable tech.

Another CS student came up with a virtual keyboard using the iPhone's accelerometer[1]. It only had ~80% accuracy[2], so was it all that useful or practical? Probably not. But could it lead to another person or company refining the technique for production in the future? Certainly.
