An input system based on hand fingertip force feedback in a virtual reality scene

Abstract

The invention discloses an input system based on hand fingertip force feedback in a virtual reality scene, which is a fast and efficient text input system suitable for moving scenes. In order to achieve the above object, the technical solution of the present invention is: the system includes: a fingertip force feedback module, which is used to obtain the state information of the user's fingertip and send it to the interaction module, and is also used to provide force feedback for the user's fingertip according to the control information. The interaction module is used to receive status information and send it to the central processing module, and is also used to receive control information and send it back to the fingertip force feedback module. The central processing module calculates the input information according to the state information, and the input information includes the pressing key value or rebounding key value of the fingertip; calculates the control information according to the input information, and the control information includes the pressing or rebounding feedback of the fingertip, and controls the The information is sent to the interaction module, and is also used to generate an input information image according to the input information, and render the input information image to the display module.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to an input system based on hand fingertip force feedback in a virtual reality scene. Background technique [0002] At present, virtual reality technology has been widely used in various fields such as entertainment, education, and medical treatment. In each application, there are a large number of scenes that require text input for recording, remote communication, etc., and many scenes are mobile scenes. [0003] In the existing virtual environment text input technology, the physical keyboard is used as the input medium for text input, but this method needs to accurately obtain the user's hand position so that the user can perceive the exact position of the keyboard key value and complete the input. Generally, computer vision is used. To obtain, the equipment cost is high, and the light environment requirements are high. At the same time, this method requires the keyboard...

AI Technical Summary

Problems solved by technology

[0008] The system lacks tactile feedback, making it difficult for users to accurately perceive the input, reducing input efficiency. At the same time, the system needs to obtain user hand information through the camera, and the user's hand can only be located in the camera's field of view, and has high requirements for the light environment.

[0009] There is currently no fast and efficient text input method suitable for mobile scenarios
