More Information
Summary:A method of for identifying multiple optical inputs to a display area with embedded photo sensors includes providing a display area with embedded photo sensors configured to display visual information; receiving a first and a second input optically transmitted to a first and a second location on the display area, respectively; processing the first and second inputs to identify at least one of (1) the location of the first and second inputs relative to the display area; and (2) a timing of the first and second inputs; and determining whether the first and second inputs originated from a single source or multiple sources based on at least their (1) wavelengths; (2) flash or pulse frequencies; (3) durations; (4) timings; (5) intensities; (6) modulation schemes; (7) projected input patterns; and (8) at least one estimated trace of the inputs; and providing first and second input information containing at least (1) their locations and (2) their timings.
