Gesture-based non-contact terminal input device

Abstract

The invention relates to the field of sensors, in particular to a temperature and humidity sensor with an intelligent interface. The system comprises a main MCU chip, a gesture recognition sensor, a power supply system, an input matrix, a USB interface, an operation information feedback module and a debugging starting module. The main MCU chip reads gesture action information captured by the gesture recognition sensor, and outputs the read information instruction to the upper system as a corresponding USB HID key value, thereby realizing a function of inputting an instruction to the system through a gesture. Instruction control of an operator can be achieved without any entity contact, and the instruction control system is novel and reasonable in design, convenient to achieve, low in cost,high in working reliability, high in practicability and high in application and popularization value.

Description

technical field [0001] The invention relates to the field of input devices, in particular to gesture-based non-contact terminal input devices. Background technique [0002] In industry and civilian use, many times the input equipment of the control terminal requires the operator to directly touch the control, but due to the harsh working environment, or a lot of pollutants, or a large number of operations, it will cause failure after a short period of use. The phenomenon of accurate input, especially in scenarios such as factory workshop terminal operations and automatic ticket machines at railway stations, whether it is a touch screen, keyboard or mouse, which are commonly used input methods, has this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a gesture-based non-contact terminal input device. The present invention recognizes the type of input keyboard for the upper system, and can identify the type of ...
