G06F 3/042 - Digitisers, e.g. for touch screens or touch pads, characterised by the transducing means by opto-electronic means
G06F 3/0481 - Interaction techniques based on graphical user interfaces [GUI] based on specific properties of the displayed interaction object or a metaphor-based environment, e.g. interaction with desktop elements like windows or icons, or assisted by a cursor's changing behaviour or appearance
An image capture method comprises generating a synchronization signal based on modulated illumination; and synchronizing image frame capture of at least one image sensor using the synchronization signal with the illumination timing of an active pointer within a region of interest in the field of view of the at least one image sensor.
H04N 5/351 - Control of the SSIS depending on the scene, e.g. brightness or motion in the scene
G06F 3/0354 - Pointing devices displaced or positioned by the user; Accessories therefor with detection of 2D relative movements between the device, or an operating part thereof, and a plane or surface, e.g. 2D mice, trackballs, pens or pucks
G06F 3/042 - Digitisers, e.g. for touch screens or touch pads, characterised by the transducing means by opto-electronic means
