Gesture recognition sensor and operating method thereof

Abstract

The present invention provides a gesture recognition sensor and an operating method thereof. The gesture recognition sensor comprises a phase-locked loop PLL in which waveform programming can be carried out, a voltage-controlled oscillator VCO, a transmitting antenna, receiving antennas, a mixer, an intermediate frequency analog circuit, an analog-to-digital converter ADC and a signal processing module; the voltage-controlled oscillator VCO is connected with the phase-locked loop PLL and the transmitting antenna; the mixer is connected with the receiving antennas and one terminal of the intermediate frequency analog circuit; and the analog-to-digital converter ADC is connected with the other terminal of the intermediate frequency analog circuit and the signal processing module. A recognition method complete different from a traditional gesture recognition sensor is adopted by the sensor, and the sensor has high reliability and recognition precision.

Description

technical field [0001] The invention belongs to the field of gesture recognition, in particular to a gesture recognition sensor and a working method thereof. Background technique [0002] Gesture recognition is the most direct and effective means of human-computer interaction. Through gesture recognition technology, users can use gestures to control various electronic devices around them. The operation is simple and fast, such as controlling mobile phones, computers, and vehicle-mounted electronic devices. Due to the high diversity and complexity of human gestures, it is extremely difficult to achieve more accurate and reliable gesture recognition, which is why there are no mature gesture recognition solutions currently on the market. At present, there are generally two technical solutions for gesture recognition: 1. Gesture recognition system based on data gloves; its working principle is that the user wears a special sensor glove, which is equipped with multiple detectable...

Problems solved by technology

Although the user of this solution does not need to wear additional equipment as in solution 1, it is easy to use, but its biggest disadvantage is that it is too obviously affected by the environment. In insufficient light or strong light, the data collected by the image sensor is too distorted. It is also difficult to obtain real image data through complex algorithm restoration, so its recognition reliability is poor, and it can only be used in some ideal environments
