Abstract
A camera is used to detect a position and/or orientation of an object such as a user's finger as an approach for providing user input, for example to scroll through data, control a cursor position, and provide input to control a video game based on a position of a user's finger. Input may be provided to a handheld device, including, for example, cell phones, video games systems, portable music (MP3) players, portable video players, personal data assistants (PDAs), audio/video equipment remote controls, and consumer digital cameras, or other types of devices.
