The patent name Huawei applied to the World Intellectual Property Organization (WIPO) is: "Wearable Devices and Their Gesture Entry Methods". It describes a new gesture input method that enables users to type in their backs with their fingertips.
The novelty of the invention is that the writing area is not limited to the display of the smart watch. This patent describes a new technology that projects ultrasonic or infrared signals out of the device.
This means that the user can enter on the back of his hand as well, and the smart watch still records the user's movements. As long as the user's hand at the level sensor, the message will be displayed.
Such technologies will help solve the user's interaction with the smart watch's small screen. Since the sensor can be projected in all four directions, the user can also control the watch by drawing gestures in the air. In addition, you can operate the device using actions such as double tap and long press.
Based on this innovative technology, Huawei is expected to develop new input modes for its watches. Many smart watch consumers are looking forward to the invention, hoping the related products can be listed as soon as possible.
