  • Virtual interface operation method, head-mounted display device, and computer-readable medium
    Patent number: 12287948
    Abstract: A virtual interface operation method, a head-mounted display device, and a computer-readable medium are disclosed. The virtual interface operation method includes: in response to detecting a single-finger sliding operation performed on a touch-sensitive display screen of a target device, determining a first sliding offset value corresponding to the single-finger sliding operation, where the target device is communicatively connected to a head-mounted display device; sliding an anchor corresponding to the single-finger sliding operation in a 3D virtual interface of the head-mounted display device based on the first sliding offset value and a first preset sliding ratio, and displaying a ray from a target start point to the anchor in the 3D virtual interface; and, creating a 2D virtual interface in the 3D virtual interface, and displaying an application window corresponding to the single-finger tap operation in the 2D virtual interface.
