NTT DoCoMo has developed a tiny display that clips onto a pair of eyeglasses and provides navigation services or information about local shops.

The prototype system, called AR Walker, includes a gyro sensor that can detect which way the wearer is facing to provide directions. It connects wirelessly to a mobile phone, which runs the software and provides the GPS data.

The research is being done with Olympus, and the system is currently intended only for use while walking and for use in Japan, but Ori said it might one day be available overseas. A potential use for it would be at museums or other tourist attractions.
