The system comprises a finger image sensor for capturing images relating to a finger and generating finger image data, a controller, and an emulator. The controller is coupled to the finger image sensor and is configured to receive the finger image data and generate movement and presence information related to the finger on the finger image sensor. The emulator is configured to receive the movement and presence information, determine duration corresponding to the presence of the finger on the finger image sensor, and generate data corresponding to a mouse output. In a preferred embodiment, the finger image sensor comprises one or more logical regions, each region corresponding to a positional mouse button.
