Regarding this patent, it is worth noting that the main inventor of the patent is Wayne Westerman. He is the main inventor of Apple's multi-touch technology. Westman has been a senior engineer of Apple since his company Fingerworks was acquired by Apple in 2005.
Apple gesture recognition principle;
The principle of Apple Watch's gesture control function is to recognize the subtle movements of hand muscles and tendons through built-in motion sensors such as accelerometers and gyroscopes, combined with machine learning and optical heart rate sensors, and then convert these motion data into gesture control effects.
Apple has been studying the gesture recognition function of Watch for many years and obtained two related patents last year. At the same time, the functions of Apple AR glasses previously exposed by Jon Prossor include gesture recognition. Perhaps in the future, Apple may combine AR glasses with Apple Watch to realize gesture operation, which is somewhat similar to Facebook's AR/VR wristband scheme.
