Abstract
A movement-based data input device is configured to receive at least one reflected signal generated upon reflection of at least one optical signal by blood vessels of an object. The data input device may generate pattern information regarding the blood vessels of the object based on the received reflected optical signal. The data input device may determine a user input motion based on the pattern information.
