Embodiment Construction

[0023] Existing wearable, helmet-mounted, and glasses-type computers often can only output some video information. In addition, the external physical keyboard that can realize information input is inconvenient to carry, so a virtual keyboard is needed to make up for the shortage of wearable computers. The present invention uses augmented reality technology to superimpose a keyboard pattern by software in the wearable computer display device, and the keyboard corresponds to the scene in the operator scene acquisition device one by one, and the augmented reality technology realizes mixing finger motion information and virtual keyboard through position correspondence , the operator can input as long as he is in the effective area of ​​the field of vision, and can watch the video of his fingers inputting on the keyboard in real time.

[0024] The present invention proposes a method for realizing character input through a head-mounted display device with a scene collection function....

Abstract

The invention discloses a head-mounted visual display equipment-based input method and a head-mounted visual display equipment-based input device, and belongs to the technical field of character input of computers and the like. The requirements of wireless Internet access, environment detection, business office and the like of operators in complex environments are met. According to the technical scheme, the head-mounted visual display equipment-based input device comprises a scene acquisition module, a processing module and a display module, wherein the scene acquisition module comprises a camera, an optical lens, a camera driving circuit and a sensor, which are sequentially connected; the processing module is used for establishing mapping relationships among an effective input area, imaging areas of input scenes and a keyboard area according to the input of the scene acquisition module, forming the mixing information of finger movement and a virtual keyboard in the display module through enhancement software in the processing module, and projecting the mixing information to retinas of a user through a projector; and the display module is used for displaying the output information of the processing module to the user. The method and the device are mainly applied to the character input of the computers and the like.

Description

technical field [0001] The invention belongs to the technical field of character input of computers and the like. Specifically, it relates to a character input method and device based on a head-mounted visual display device. Background technique [0002] Mouse and keyboard are character and information input devices commonly used. Due to the limitation of volume and weight, the use of keyboard and mouse of portable devices is limited. From a functional point of view, the keyboard is a prompting device used to correspond to a specific character / character set. Therefore, the existing portable devices also adopt the virtual keyboard based on the touch screen to realize character input. Character input is achieved by touching the area where the characters are displayed on the screen with a finger or a pen. Such devices require the screen to be equipped with additional touch detection devices such as capacitive films or optical sensors. When typing, your finger will cover pa...
