Touch button identification system

Abstract

The invention discloses a touch button identification system, which comprises touch buttons, an acceleration sensor and a button effectiveness judgment circuit, wherein the touch button is used for sensing the touch of a human body over the button, and outputting an electrical signal; the acceleration sensor is connected with the touch button, and is used for detecting the impact of the human body on the touch button when the button is touched by the human body; and the button effectiveness judgment circuit is connected with the touch button and the acceleration sensor, judges the effectiveness of the touch button according to detection results of the touch button and the acceleration sensor, and outputs the electrical signal or outputs a signal in a mechanical touch point way. The touch button identification system judges the touch behavior of the human body over the button by utilizing the degree of impact of the human body on the button when the human body touches the button, and judges the effectiveness of the button in combination with own response of the button to the touch, thereby improving the reliability of the touch button and preventing false triggering. The touch button identification system also can enable patients with visual impairment to use the touch button by setting a proper impact acceleration judgment threshold value.

Description

technical field [0001] The invention relates to an identification system for touching buttons. Background technique [0002] A touch button is a non-mechanical contact button. At present, there are various types of touch buttons such as capacitive sensing trigger button, electric field sensing trigger button, resistance sensing trigger button, infrared sensing trigger button, inductive sensing trigger button and visual trigger button. All types of tactile buttons are characterized by long life due to the absence of mechanical contacts, and can improve customer experience. However, these novel touch buttons are easily affected by the environment, such as changes in the electromagnetic field around the buttons, changes in temperature and humidity, and / or dust, which will affect the sensitivity and reliability of the touch buttons. Since the button is touch-type, a slight touch will cause the button to act, which will cause confusion to the user when the visually impaired pat...

However, these novel touch buttons are easily affected by the environment, such as changes in the electromagnetic field around the buttons, changes in temperature and humidity, and / or dust, etc., which will affect the sensitivity and reliability of the touch buttons

Since the button is touch-type, a slight touch will cause the button to act, which will cause confusion to the user when it is used by visually impaired patients (blind or amblyopic patients)
