The Lecoo Douzhanzhe G1 AI Shooting Glasses bring users an excellent human-computer interaction experience. Its external sound effect is as clear as if the sound is close to the ear. The touch buttons for playback and photo-taking operations are sensitive and convenient. The flickering prompt of the RGB colorful light when shooting brings a unique interactive experience.
In the realization of interactive functions, Awinic's "sound", "light" and "hand" have played an important role. In terms of "sound", Awinic's normal-pressure digital power amplifier is adopted, which presents pure and natural sound, bringing users a high-quality audio experience. In the design of "light", Awinic's industry-leading small-package RGB lamp driver is used, which can realize 16 million color mixing and 256-level dimming breathing effects, with rich and delicate light changes. In the control of "hand", Awinic's 8-channel touch chip is adopted, supporting two-point wearing detection and sliding gesture recognition. The operation is simple and smooth, and the corresponding functions can be easily completed with one touch, which greatly improves the convenience and interest of interaction.
