Bracelets and Google Glass could be used to form a virtual keyboard on any surface

• A team at Sweden's Mälardalen University is developing a system that combines a pair of bracelets with a wearable device such as Google Glass
• It create a virtual keyboard that only its user can see.
• The bracelets will be worn on the wrists or hands depending on the final design and will contain sensors that are able to see the positions of the finger tips, and movements of the user's hands.
• The data will be wirelessly relayed to a device and will display a keyboard within the user's field of vision.
•  As the user taps their fingers on the real-world flat surface, the keys of the virtual keyboard will correspondingly be activated.
