Non-contact ultrasound distance detection uses the TOF principle to calculate the distance to the object being measured. It is not affected by light, magnetic fields, and electromagnetic interference, and is also suitable for highly corrosive liquids such as acidic liquids. It has a short response time and can achieve real-time measurement without lag. Specific application areas include robotic arms, drones, sweeping robots, liquid level detection, etc.
The dialogue mode based on touch screen and buttons is gradually unable to meet the needs of the majority of customers. Ultrasonic gesture recognition can control the device screen through wireless sensing to better improve the customer experience. It is specifically used in smart phones, watches, smart home appliances, household robots, wearable devices, children’s teaching aids and other fields to promote the human-machine dialogue mode to be more intelligent and natural.
