Abstract: A device is provided which allows multidimensional information signals concerning coordinates, directions and the like of an object to be input to a CPU exactly as intended by an operator on a non-contact basis, and without restrictions on the place where it is used. Angular velocity detectors (4), (5), and (6) are provided on the X-axis, Y-axis, and Z-axis, orthogonal to each other of an operation unit which is shaped to be easily gripped by an operator or to be mounted on an articulation, shoulder, or head. The operation unit (1) is rotated and moved and, when the operator wishes to input information, push-buttons (2) and (3) provided on the operation unit (1) are turned on/off to command the start or stop of the counting of the output of the angular velocity detectors (4), (5), and (6). In response to the command, the angular velocity signals of the axes are converted into information to be input to the CPU through V/F converters, pulse conversion circuits, gate circuits, and counter circuits.
