According to this article in BusinessWeek, the transparent touchscreen is sensitive enough to discern signs, gestures, shapes, and even body parts. For instance, users can answer calls by simply holding the phone up to their cheek.

As a stodgy phone user who can still remember the days of rotary-dial phones, and who continues to view his cell phone as a nuisance as much as a convenience, I am probably not the best person to assess whether the market will respond to a buttonless, mood-changing, origami-like phone that can be worn around the neck in the shower.
I am, however, confident that mobile communication devices will continue to advance and change, and that this trend of viewing cell phones as fashion accessories as much as functional devices will grow.
