Outside of a fashion week couture fashion tech concept house like Anrealage[1], what will this do for us? Project Jacquard strikes me as a solution to a problem, but I can't think of a single problem it solves. A smart watch tells time, streamlines notifications, and maybe keeps me in shape, but this? What will this do for me?
If your display is in your contact lens, how are you going to dismiss a notification or reject a phone call? Well maybe you just have to swipe the right way on your jacket sleeve like they did at the key note.
