The Magic of Gesture Control

Gesture recognition is a technology that uses algorithms to recognize gestures. It mainly utilizes time-of-flight technology, millimeter wave radar, and structured light technology to sense the actions of participants, enabling them to control or interact with devices through simple gestures. With the help of digital interaction technology, the "distance" between people and viewing objects has been gradually reduced, and the legendary "retrieval from space" is approaching reality.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

There are three main methods for implementing gesture recognition: 1 Time of flight (ToF) technology, the basic principle of which is based on the flight time of photons in the air to determine the position of fingers, is therefore called time-of-flight technology. The basic process is to calculate the time it takes for the light emitted by the light-emitting element to return to the photosensitive element after hitting the target object, in order to determine the state and position of the hand. two Structured light technology, also known as structured light technology, refers to the use of a light emitter to project specific light information onto a target object and background. After being collected by a photosensitive element, the depth and position information of the object are calculated based on the changes in light caused by the object, in order to restore the three-dimensional space where the object is located. three Millimeter wave radar operates at a higher frequency, resulting in a shorter wavelength. The electromagnetic waves emitted by millimeter wave radar have a wavelength in the millimeter range, hence it is called millimeter wave radar. Its basic principles and.
