Sony patents camera system that ignores its own controller movements

Sony has been granted a patent for a device that uses an event-based camera to track motion while a user operates a physical input device. The system works by marking specific camera signals with a digital flag whenever the input device is active, allowing the computer to distinguish between external movement and the user's own hand motions.

Why it mattersThis technology could help gaming controllers or VR headsets ignore the user's own hand movements, leading to more accurate tracking of the environment or game world.

In the filing’s own words

Provided is an electronic device including an event-based vision sensor, a physical input/output unit, and a control unit configured to set a predetermined flag to an event signal generated by the event-based vision sensor during operation of the input/output unit.

What exactly they claim (claim 1)

1. An electronic device comprising: an event-based vision sensor; a physical input/output unit; and processing circuitry configured to simultaneously execute transmitting a control signal to operate the physical input/output unit and setting a predetermined flag to an event signal generated by the event-based vision sensor during operation of the physical input/output unit.
