Sony has unveiled a concept rival to Google Glass that can be attached to any pair of glasses.
Called the Attach, the smart glasses can be attached via the frame. They have a small display, camera, and the ability to communicate with it via voice.
The glasses could be used for any purpose, but Sony has been pitching the Attach at CES this year as a sports-focused device that can track your fitness, help you become better at golf, record snow sports and other activities.
Will Attach help people get healthy? Or will this be another device to enjoy on the couch?
