  • Patent number: 10739863
    Abstract: A mobile terminal detects a gesture on a touchscreen; when a pressure value of the gesture exceeds a first threshold P1, starts to record change information of the pressure value of the gesture; when the pressure value is lower than a second threshold P2, stops to record the change information of the pressure value; parses the recorded change information of the pressure value; when the parsing of the change information indicates that the gesture includes at least two consecutive effective screen presses, determines that the gesture matches a first instruction; and in response to the first instruction, presents a first graphical user interface on the touchscreen. In this manner, press gesture identifying precision can be improved, and a problem that it is difficult for the touchscreen to distinguish a long press from the press gesture can be avoided.

  • Patent number: 10725308
    Abstract: A head-mounted display (HMD) presented herein comprises a shell and a controller. The shell encloses a display element and includes a dynamic attenuator having one or more controllable pixels that control an amount of light from the local area to an eye box of the HMD. The controller determines, based on positional information for one or more objects in a local area surrounding the HMD, whether a user wearing the HMD is within a threshold distance of an object in the local area. Responsive to the determination, the controller identifies a field of view that includes the object. The controller instructs the dynamic attenuator to allow light from the local area over the identified field of view into the HMD.
