Computer input unit, dual-spectrum data input processing method and sensor thereof

Abstract

The invention discloses a computer input unit with dual-spectrum and dual-coordinate output, a dual-spectrum data input processing method and a sensor thereof. The computer input unit comprises a first luminous source, a second luminous source and a sensing module, wherein the first luminous source is used for generating a first projection light beam with first wavelength; the second luminous source is used for generating a second projection light beam with second wavelength; and the sensing module comprises a filtering unit, a light signal receiving zone, a control unit and a storage unit, the filtering unit respectively filters the first projection light beam with first wavelength and the second projection light beam with second wavelength, the light signal receiving zone receives the first projection light beam to obtain first image data and receives the second projection light beam to obtain second image data, the control unit compares the obtained first image data with the obtained second image data so as to figure out first displacement data and second displacement data, and the storage unit stores the first displacement data and the second displacement data.

Description

technical field [0001] The invention relates to a computer input device and a data input processing method thereof, in particular to a dual-spectrum dual-coordinate output computer input device, a dual-spectrum data input processing method and a sensor thereof. Background technique [0002] A computer input device generally refers to a hardware device (Hardware Device) that can input a coordinate displacement signal to a computer device (such as a personal computer, a notebook computer, or a personal digital assistant, etc.). There are many types of visible computer input devices, such as a mouse, a trackball, etc. Devices, trackpads, pen tablets, joysticks, etc. are included. Wherein, except that the mouse can input coordinate displacement signals to the computer device according to the movement of the user, the mouse is also provided with a scroll wheel, which can also control the vertical scroll bar or horizontal scroll bar of the windowed interface, and is also provided ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned computer input device with an optical sensing window can improve a lot of operational convenience, it also uses two optical sensing modules (one for the optical sensing window and the other for controlling the mouse pointer), and This increases the production cost of the computer input device, and the power consumption is also relatively increased. In addition, the computer input device needs to increase the volume space to accommodate two optical sensing modules
