Problems solved by technology

The existing optical pointing sensor senses the image caused by the finger. When the image moves, the sensor senses and outputs the value of the movement. However, this method cannot sense the function of the click input command that the user wants to execute. In view of this, an existing optical pointing sensor installs a metal dome switch at the bottom to perform the function of inputting commands by pressing with fingers
[0003] However, the above-mentioned optical pointing sensor performs the function of input command by pressing, which is inconsistent with the current usage habit of inputting by finger touch, and is inconvenient to operate

Embodiment Construction

[0020] In order to illustrate the technical content, structural features, achieved goals and effects of the present invention in detail, the following examples are given to describe in detail with accompanying drawings.

[0021] see figure 1 and figure 2 The optical pointing and navigation device 100 of the present invention is mounted on the circuit board 1 and includes a sensor 2 , a photoelectric crystal 3 , an LED light source 4 , a light-shielding housing 5 , a lens set 6 and a touch housing 7 .

[0022] The sensor 2 is installed on the circuit board 1. The sensor 2 can convert the optical signal into a digital signal. When the light irradiates on the upper surface of the sensor 2 and the light moves, the sensor 2 can sense its optical signal. signal and calculate the displacement of light (that is, digital signal). The photoelectric crystal 3 is installed on the side of the sensor 2, and the photoelectric crystal 3 can convert the optical signal into a binary signal. ...

Abstract

The invention discloses an optical pointing navigation method, which is suitable for an optical pointing navigation device. The optical pointing navigation device is installed on a circuit board and includes a sensor, a photoelectric crystal, an LED light source, and a light-shielding shell 1. A lens group and a touch housing. The optical pointing and navigation is: the infrared light emitted by the LED light source penetrates the touch housing and is reflected, then passes through the lens group and enters the sensor and photoelectric crystal through the light-transmitting hole. On, so as to excite the sensor and photoelectric crystal to generate digital signal and binary signal, and complete the input of the navigation command.

Description

technical field [0001] The invention relates to a pointing and navigation device, in particular to an optical pointing device and method. Background technique [0002] With the development of science and technology, electronic products are becoming more and more diversified, and the way users use and control electronic products tends to be more convenient and fast. Nowadays, popular smart phones, mice and other products are mostly navigated and controlled by finger touch. For the input of function commands, using an optical pointing sensor (Optical Finger Navigation) is one of the ways to realize finger touch input. The existing optical pointing sensor senses the image caused by the finger. When the image moves, the sensor senses and outputs the value of the movement. However, this method cannot sense the function of the click input command that the user wants to execute. In view of this, an existing optical pointing sensor is equipped with a metal dome switch at the bottom...
