CPC Class H04N

The present invention relates to an electronic wrist wearable device that uses image and inertia sensors to track motion of hand and wrist of a user, and is able to determine locations (relative to a stationary object in physical environment), and discrete and motion hand gestures. The wearable device can also emulate various data input devices by matching the determined gestures with preregistered gestures and sending the data associated with the matched gesture to a relevant computer device. The wearable device can also send the said tracking information of the hand and the wrist to at least one external computer, which can process the received information to simulate hand motion, and to determine discrete and motion hand gestures. The said computer can also emulate various data input devices by matching the determined gestures with preregistered gestures and using the data associated with the matched gesture.

The present disclosure provides a scanning imaging part, and related products and methods. The scanning imaging part includes a transparent body, a light blocking ink, a charged liquid droplet, and a microfluidic component. The transparent body may include a first face and a second face opposite to each other. An image sensor may be arranged on the second face. The charged liquid droplet and the light blocking ink may be insoluble with each other, and may be filled in a liquid flow channel. The charged liquid droplet may transmit at least a part of light incident from the first face through the charged liquid droplet and to the image sensor. The microfluidic component may drive the charged liquid droplet to move in the liquid flow channel. Thereby, light incident from the first face may be scanned via the charged liquid droplet and form a scanning image by the image sensor.
