Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The invention provides an adaptive key-value display input system for virtual reality, which consists of figure 1 As shown, the system includes an input module, an algorithm module and a display module.

[0029] The input module is an input device used in the virtual environment, including a keyboard, used to obtain the current input key value of the user, and call an input character correction algorithm to correct the current input key value. In the present invention, the keyboard may be a physical keyboard or a virtual keyboard. If it is a virtual keyboard, the input module obtains the real-time position of the user's finger, and uses the key value corresponding to the real-time position of the user's finger on the virtual keyboard as the user's current input key value.

[0030] The display module is a virtual reality helmet or an augmented disp...

Abstract

The invention discloses a self-adaptive key value display input system for virtual reality, which can improve the input efficiency. Specifically, an input module is used for obtaining a current inputkey value of a user and calling an input character correction algorithm to correct the current input key value. A display module is used for displaying the virtual keyboard and the current input key value in the user visual field virtual environment. An algorithm module comprises the following algorithms: a character prediction algorithm is used for calculating a prediction key value according toa previous input key value; a display key value correction algorithm corrects the display range of the predicted key value according to the predicted key value and a preset correction area, and sets the display size and the display duration; and an input character correction algorithm judges that if the current input key value is in a preset correction area around the predicted key value, the current input key value is corrected into the predicted key value. A display module displays the predicted key value in the virtual keyboard according to the corrected display range of the predicted key value and the set display size and display duration.

Description

technical field [0001] The invention relates to the technical field of input assistant systems for virtual reality, in particular to an adaptive key-value display input system for virtual reality. Background technique [0002] At present, in virtual reality, users can use physical QWERTY keyboards or virtual keyboards for input, but because users in HMDs cannot see their fingers or real keyboards, it is easy to cause input errors, especially adjacent key input errors, although there are algorithms The user's input error can be effectively corrected, but this method is likely to cause user cognitive errors. [0003] At present, some researches use the real QWERTY keyboard as the input device in the virtual environment, and use the correction algorithm to correct the input when the user cannot see the keyboard in the virtual environment. The algorithm can correct a large number of errors entered by the user. [0004] In the virtual environment, the user cannot visually see t...
