Method and apparatus for exhibiting virtual keyboard

Abstract

The invention discloses a method and apparatus for exhibiting a virtual keyboard. The method herein includes the following steps: modeling a user's two hands and the object surface so as to establisha two hand model of the user and a surface keyboard model in a virtual reality scenario; making up the fingerprint models in the two hand model that are blocked so as to establish a standard two handmodel; based on the current spatial position relation among fingers of the standard two hand model, performing adaptive regulation on the key distance of the surface keyboard model so as to obtain anadaptive keyboard model that is adaptive to the current spatial position relation among the fingers; and exhibiting the adaptive keyboard model in the virtual reality scenario. According to the application, the technical solution can realize precise man-machine interaction.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a method and device for displaying a virtual keyboard. Background technique [0002] Currently, in human-computer interaction, information input methods adopted by users usually include the following types: [0003] 1. Traditional physical interaction, that is, input is completed through real physical devices, such as widely used mice, keyboards, gamepads, remote controls, etc. The disadvantages of this method are: the size of the physical interaction is too large to be used for micro-devices; the function is very restrictive and can only solve the input requirements of one device (for example, the mouse cannot be used on mobile phones); the fixed size of the device cannot adapt to different groups of people. (People with larger hands feel that the keyboard spacing is small, while people with small hands feel the opposite). [0004] 2. Wearable entity interac...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: the size of the physical interaction is too large to be used for micro-devices; the function is very restrictive and can only solve the input requirements of one device (for example, the mouse cannot be used on mobile phones); the fixed size of the device cannot adapt to different groups of people. (People with larger hands feel that the keyboard spacing is small, while people with small hands feel the opposite)

The disadvantage of this method is: it must be worn to interact; it can only recognize simple motion information of the wearing part

The disadvantages of this method are: the interaction range depends on the size of the device; the hand blocks the interface when interacting

The disadvantage of this method is that the hand cannot interact on the support surface, otherwise the support surface will be misjudged as a hand and make an error

The disadvantages of this method are: the support surface must be flat (not uneven); the recognition accuracy is low, and it is easy to touch by mistake; it is impossible to recognize the strength of the finger pressing the surface
