Forget all those heads-up, holographic approaches to hands-free computing that put data in front of your eyeballs. Japanese firm NS West has developed a wearable PC for your ear.
It looks like a hearing aid, and includes a compass, GPS tracking, a gyro sensor, a barometer, a speaker, and a microphone. It also has infrared sensors that can monitor the movements of your ear as you change facial expressions, allowing hands-free operation. It is battery powered and includes built-in storage, so it could accept software, apps, and files, and includes a pulse monitor and thermometer for health monitoring.
The initial prototype was built at Hiroshima University. The developers expect to have a finished product available by the end of 2015.
You can see a demonstration of the device in the video below.
