 Five freedom degree, mixed mouse device
Abstract：
 A 5 degree-of-freedom (DOF) mixed mouse device belongs to the field of mouse technology, which is characterized in that: the two side walls of the mouse are provided with two rolling-wheels, an internal circuit board is provided with two photoelectric sensing devices separately corresponding to the two rolling-wheels, the data output ends of the two sensing devices are separately connected with data input ends of a microcontroller on the circuit board, the microcontroller determines the conversion value on the basis of the obtained data of current state and the data of previous state, and then the data is delivered to the computer through interruption and activation; the computer is equipped with a filter driver, which is used for filtering the added data of 2 DOF rotated around an X-shaft and a Y-shaft to conduct communication with application programs. The invention provides the 5 DOF mouse, which can realize three-dimensional space positioning and mutual input, thereby not only being completely compatible with the prior two-dimensional mouse (3 DOF), but also being capable of realizing the rotation around the X-shaft and the Y-shaft under the operation of a thumb and a middle finger or the thumb and a ring finger.
