<p>PROBLEM TO BE SOLVED: To minimize the movement of the line of sight in the case of a device operation during driving a vehicle, etc., to secure safety, further, to unnecessitate the operation of switches which are fixed at specified positions in a device operation because the operation is performed by moving a hand, etc., within a specified range, to exclude a physical arrangement restriction of switches, and to provide virtual switch functions within a range where an operation is easily performed. SOLUTION: This device is provided with one or plural light emitting sources 15a,... which are arranged in n-dimension (n is an integer 1 to 3) and one or plural light receiving parts 16a,... which are arranged in n-dimensions to correspond to the sources 15a,.... Entire information or partial information about the position, size, moving direction, moving quantity and moving quantity change rate of a user's body or an object that is carried by the user is detected in a detection area 17 that is surrounded by the sources 15a,... and the parts 16a,..., and the detection result is used as input information to electronic equipment.</p> |
