This is the future: NTT DoCoMo demoes the one-handed Grip UI, and the "i beam" eye-operated tablet
eye-tracking technology utilizes line-of-sight detection with near infrared light, and special camera unit that can follow the eye of the beholder. The Grip UI is aided by pressure-sensitive phone sides, that can detect up to five levels of squeezing, as well as the way you are holding the phone. Thus the handset can be programmed to execute apps, or do some other action.The
Galaxy Note II and the like.
These pressure-sensitive sides are a step in the right direction, and a combination of them with i beam would be nice to have, but a good old Back button on the side, right under out thumbs would do just as good for now. What do you think about the concepts shown below?
