Abstract

The invention provides a virtual keyboard interaction method and system. The method comprises the following steps: pre-training a fingertip detection model; obtaining three-dimensional space position coordinates of all fingertips on the to-be-detected image data relative to a preset reference position through the fingertip detection model; based on the three-dimensional space position coordinates, determining a touch area corresponding to the fingertip; when the touch area is overlapped with a sensing area of a preset virtual keyboard, acquiring volume information of the touch area falling into the sensing area; and based on the volume information and a preset rule, judging whether a virtual keyboard where a sensing area corresponding to the touch area is located is triggered or not. The character input efficiency and accuracy can be improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of virtual keyboards, and more specifically, to a virtual keyboard interaction method and system. Background technique [0002] With the development of fields such as computer games, health and safety, industry and education, the application of artificial reality systems in these fields is becoming more and more common. For example, artificial reality systems are being integrated into mobile devices, game consoles, personal computers, movie theaters, and theme parks. VR), Augmented Reality (AR), Mixed Reality (MR) or some combination and / or derivative thereof. [0003] With the popularity and development of artificial reality in all walks of life, the keyboard has been inherited as one of the most common input devices for users to interact with artificial reality systems. Usually, the virtual keyboard is mainly rendered and projected directly in front of the user's viewing angle by a virtual realit...
