The movement to leave smartphones safely in a pocket continues with the new device, which turns any surface into a touch screen and lets you answer your phone by swiping your shirt.
The device will be worn on the fingertip and will feature two small cameras. One camera will be able to detect the texture of the nearest surface while the other will sense motion, enabling the device to both sense swipe movement and alter the input according to the material. This extra bit of information will allow the device to give different commands if swiped on cloth rather than wood, for example.
The device is supposed to have an enhancement for devices rather than as a replacement for a mouse.
