Abstract: A head-mounted display device, where when the head-mounted display device enables a low power consumption display mode, a left-eye display system and a right-eye display system alternately display an image. A switching time interval for the left-eye display system and the right-eye display system to alternately display the image is determined based on a current display mode. Different current display modes correspond to different switching time intervals, or correspond to a same switching time interval. Therefore, in the low power consumption display mode of the head-mounted display device, one display system displays the image within a same time period to reduce power consumption of the head-mounted display device.

Abstract: A device interaction method, an electronic device, and an interaction system are provided. The device interaction method includes: After detecting that a VR/AR device connected to an electronic device enters a predetermined operating mode, the electronic device generates at least two interaction interfaces used by the VR/AR device to perform an interaction operation, and displays at least one of the interaction interfaces in a display area of the electronic device.

Abstract: Smart glasses, and an interaction method and an interaction apparatus thereof are provided. The interaction method includes: receiving a message sent by a communications device; displaying a prompt identifier of the message at an edge of a display area of the smart glasses; and performing, if the head of the user wearing the smart glasses rotates in the first direction, a screen sliding operation or page turning operation to display the detailed content of the message in the display area.

Abstract: A head-mounted display apparatus-includes a lens frame, a lens, and a display module. Both the lens and the display module are disposed on the lens frame. The lens includes a first part and a second part. The first part is adjacent to the second part. The first part is configured to transmit ambient light. The second part is configured to transmit the ambient light and display light emitted by the display module. A ratio of the transmittance of the second part to the transmittance of the first part is within a threshold range. In one embodiment, the threshold range may be between 0.5 to 1.5.
