Abstract

A display device capable of superposing a virtual keyboard is suitable for providing a display picture for display of one screen of a head-mounted display and comprises a keyboard processing module, an operation control module and an output module. The keyboard processing module is used for receiving one keyboard touch signal related to a key touch position and outputting the signal to the operation control module. The operation control module operates at least the display picture including one virtual keyboard picture according to a key touch position, the virtual keyboard pictures include multiple key portions corresponding to multiple keys of an entity keyboard, and the key portions corresponds to different letter symbols. By starting from a display device providing the display picture to operating the display picture including the virtual keyboard pictures, the virtual keyboard pictures non-limited to an operating system or a display mode can be displayed without additional hardware manufacturing costs.

Description

technical field [0001] The invention relates to a display device, in particular to a display device capable of superimposing a virtual keyboard on a head-mounted display screen. Background technique [0002] Virtual reality (virtual reality, abbreviated as VR) is an interactive display technology that is actively developed at present, and generally needs to be used in conjunction with a head-mounted display. However, when a user wears a head-mounted display, the view is completely blocked The physical keyboard is inconvenient, so when you need to enter a lot of text, you will encounter difficulties. [0003] The intuitive solution is to display a virtual keyboard in the user's field of view. However, due to the limitations of the operating system, graphics engine, application programming overlay permissions, etc., it is very difficult to implement in practice. For example, the user may be running on a personal computer. A large-scale 3D game written using Microsoft DirectX ...
