Abstract

The present invention provides a headset display device-based virtual keyboard input method. The method comprises the following steps: displaying an identifier control on a virtual keyboard display interface, wherein the identifier control is corresponding to a virtual keyboard key on the virtual keyboard; according to a user manipulation instruction, switching the virtual keyboard key corresponding to the identifier control; and according to the virtual keyboard key currently corresponding to the identifier control, inputting the character corresponding to the virtual keyboard key. The present invention also provides a headset display device-based virtual keyboard input apparatus. According to the headset display device-based virtual keyboard input method and apparatus provided by the present invention, the operation complexity when the user inputs content through the virtual keyboard of the head-mounted display device can be effectively reduced, content input efficiency can be significantly improved, and the input experience of the user of the head-mounted display device can be improved.

Description

technical field [0001] The invention relates to the technical field of smart wearable devices and human-computer interaction, in particular to a virtual keyboard input method and device based on a head-mounted display device. Background technique [0002] Virtual Reality (VR) technology simulates a virtual three-dimensional world through computer systems, and provides users with visual, auditory, tactile and other sensory simulation experiences with the help of display systems and interactive systems, while users can interact with virtual scenes Interaction brings users an immersive experience. Therefore, interactive technology is one of the key technologies for the realization of virtual reality systems, which determines how users interact with objects in the virtual world. [0003] In the existing technical solutions, the head-mounted display device controls the cursor or anchor point to move in the virtual keyboard by detecting the user's head movement, or by detecting t...
