PROBLEM TO BE SOLVED: To convert user's finger trajectory to an input signal without touching a sensor.SOLUTION: When a finger of a user traces from 201a to 201b and 201c, for example, and draws a trajectory as shown by arrows 202, and 203, a motion input device 1 acquires images captured by cameras 101, 102, detects a fingerprint of the user in the image and stores the trajectory in a fingerprint position database 50. The motion input device 1 extracts a motion pattern matching the finger trajectory of the user from a motion pattern database 51, and extracts an input signal associated with the motion pattern. The finger trajectory of the user is converted to an input signal when the device behaves in the same way as when the extracted input signal is actually input. |
