IT House news on March 6, Google applied for a new patent, allowing users to perform a series of operations without directly touching the device.
According to Lets Go Digital, Google recently approved a patent to operate wearables through a "skin interface" or gesture control through a skin.
The patented technology can be applied to a wide range of wearable products, from headphones and smart watches to virtual reality headsets and smart glasses.
Currently, wearables operate primarily through voice commands, built-in microphones, and touch input. However, physical controls, such as touch or tapping, may cause unwanted noise or discomfort to the user. In addition, Google said that touch will affect the performance of the antenna.
The patent applies for a method whereby a user swipes or taps on a skin near the wearable device, the gesture generates waves, and sensors and accelerometers detect movement and determine the gesture type.
As you can see from the patent image, the user can swipe up, down, left and right, or tap next to the wrist, next to the ear.
IT Home learned that the Link Buds headset released by Sony last month uses a similar technology, which supports wide-area clicking, tapping the ear area near the cheek to play, pause and switch.
