Description

technical field [0001] The present invention relates to an optical control device, and in particular to a multi-dimensional optical control device. Background technique [0002] Applied to the control methods of existing digital creation, industrial design or related electronic products, such as: keyboard, mouse, touch panel and other flat control devices, with the development of technology industry and the development of related products, when users need to use space six For three-dimensional control, the existing two-dimensional control device can no longer meet the needs of users. It must be equipped with other control devices, such as buttons, keyboards, etc., to complete the six-dimensional control function, which not only increases the difficulty of control , Using the wrist joint for a long time is easy to fatigue and even cause injury; in addition, the control method of replacing space with a plane is not an intuitive control method of the human body, which often lea...

[0007] US 6,480,183 uses the principle of capacitive sensing to sense the actuation of the conductor of the mover to complete the plane displacement and rotation control functions. However, due to the use of capacitive sensing, the relative position of the conductor and the sensing plate is limited, so direct space control cannot be performed. Function

[0008] US 5,969,520 uses multiple magnetic components to sense the movement of the magnetic ball to complete the plane control function; however, the relative position of the magnetic ball and the magnetic component will affect the sensing accuracy of the magnetic component. In addition, the magnetic component is susceptible to external magnetic conduction. The interference of objects will affect the position determination, and the magnetic ball will also attract and collide with external magnetic objects.

[0009] US 6,774,887 completes the plane control function through the contact between the conductor and the resistor, but the conductor and the resistor are easily affected by moisture or oxidation, resulting in poor contact, and if the space control function is to be achieved, other conductors and resistors must be installed, so that Part volume and cost increase
