Multidimensional signal input device
First Claim
1. A multidimensional signal input device comprising:
- an operation unit including;
a plurality of angular velocity detector means, on orthogonal axes, each for detecting an angular velocity of said operation unit, andoperation buttons on an outer surface thereof,voltage-to-frequency converter means, connected to outputs of said angular velocity detector means, each for producing a converted output,sign detection circuits connected in parallel with said voltage-to-frequency converter means, each for determining a direction of said angular velocity,gate circuit means for validating or invalidating a count of converted outputs of said voltage-to-frequency converter means in response to a command timing from said operation buttons, andcounter circuit means, connected to said gate circuit means, for producing a count output corresponding to said command timing and supplying said count output to a control device for producing movement in response thereto.

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. The motion of an operator can be commanded as the operator intends in arbitrary space, thereby facilitating the movement of a robot arm and the rotation and movement on a display screen of a three-dimensional CAD system or graphic system. In addition, a person who has a handicap in his or her hand or leg can operate and issue commands.
