Few weeks earlier and I could at least have cited you guys in my PhD thesis. But then again, there are several similar projects that do wearable touch. Too few though; there I totally agree.
I can see the value in having your "turn left, now turn right" ques be a tap on the shoulder instead of a voice or floating arrow, but the sports thing and the music thing don't seem to me to be worth a whole lot. A technical marvel to be able to integrate it with a garment to the point that you wouldn't know it was there unless you were using it, but I don't think it would much enhance the experience. The music thing might be good when you're using earphones, but when you're at a concert or rave you can already feel the music.
We already naturally do this, lets not turn everything into a technology and divide ourselves even further. I can see it as a good "demonstration of empathy" but if you alteady understand empathy why is this necessary? we're just going to weaken our empathy muscles,soon everything that isn't a technology will be considered a fantasy as if it doesn't exist!
