Input system based on hand fingertip force feedback in virtual reality scene

Abstract

The invention discloses an input system based on hand fingertip force feedback in a virtual reality scene. The input system is a rapid and efficient text input system suitable for a mobile scene. In order to achieve the purpose, the technical scheme is that the system comprises a fingertip force feedback module which is used for obtaining state information of the fingertip of a user and sending the state information to an interaction module, and is also used for providing force feedback for the fingertip of the user according to control information; an interaction module which is used for receiving the state information, sending the state information to the central processing module, receiving the control information and returning the control information to the fingertip force feedback module; a central processing module which is used for calculating input information according to the state information, the input information comprising a pressing key value or a springback key value ofa fingertip, and calculating control information according to the input information, the control information comprising pressing feedback or rebound feedback of the fingertip, sending the control information to an interaction module, generating an input information image according to the input information, and rendering the input information image into a 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
