VR Interfaces: QB1: Gesture Only PC


Overview of QB1: Gesture Only PC
A novel interface paradigm computer, the QB1 is the brainchild of one Fr?d?ric Kaplan, an engineer with a background in robotic systems for Sony. He worked with designer Martino d?Esposito of EPFL in France, to create a computer system with no mouse, no keyboard, just an on/off switch, and the ability to recognise and respond to gestures.

The second prototype machine, QB1, utilises significant inbuilt artificial intelligence and automatic facial recognition tech, to try and identify, from several cameras pointing in directions all round the machine, the identity of anyone approaching it. This identity is treated as the equivalent of username, and password. Providing the machine has you on file, just stepping close to it, logs you in.

Interaction is through the hands. Once the machine has identified an active user, its cameras switch to identifying then tracking the user?s hands and fingers, obeying command sequences waved into the air in front of it. Both hands are tracked, and contrasted to one another, to allow for complex gestures, and emphasis can be placed by moving closer to the machine, or moving away. Closer equals higher priority. If the user stands or squatts, or moves about the room, QB1's monitor lifts and tracks to follow them.

At the moment, the computer is only fitted with a jukebox and a simple two player tennis game. With the jukebox the user can control via gestures and adjust the music, with the machine remembering favourite songs and settings for a given user. For tennis, the machine remembers an individual's handicap, avatar choices and playstyle in a similar manner.

Further development is proceeding, and as yet, no commercial use of the QB1 is offered.
