Content projection system and method

Abstract

The invention discloses a content projection system and a content projection method. The system comprises a fixation point detection device used for detecting a present fixation point position of eyes; an image generation device used for generating a virtual image in dependence on visualization information and the fixation point position; and a virtual image projection device used for projecting the virtual image to eye grounds in dependence on the fixation point position. In the system and the method provided by the embodiment, the fixation point position of a user can be detected in real time, imaging parameters of corresponding visualization information are obtained according to the fixation point position, furthermore the virtual image is generated and projected to the eye grounds, virtual figure information and real information can be fused better, and furthermore the user can obtain better immersion.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a content projection system and method. Background technique [0002] In a mixed reality environment, the system often displays some virtual graphic information, but the fusion display between virtual graphic information and real information has not been well resolved. For example: when the user looks at something (actual object or virtual figure), because the depth or position of the virtual figure is not placed correctly, the user cannot see the virtual figure information that needs to be seen clearly; Virtual graphics information at other depths and positions are often displayed clearly, without producing a suitable out-of-focus effect, which affects the user's real sense of immersion. For example, at present, Google Glass can only display virtual content on a virtual screen at a specific distance, so that the content cannot be well integrated into reality. Th...

Problems solved by technology

For example: when the user looks at something (actual object or virtual figure), because the depth or position of the virtual figure is not placed correctly, the user cannot see the virtual figure information that needs to be seen clearly; Virtual graphics information at other depths and positions are often displayed clearly, without producing a suitable out-of-focus effect, which affects the user's real sense of immersion

For example, currently Google Glass can only display virtual content on a virtual screen at a specific distance, resulting in that the content cannot be well integrated into reality. Therefore, the virtual screen has to be placed obliquely above the glasses. Users need to deliberately tilt the screen when viewing virtual graphics information. Viewed from above, it seriously affects the user's visual experience

In the mixed reality system with binocular stereo vision, due to the addition of a stereo depth information, the harmony between the virtual system and the real system becomes more difficult, and the wrong setting of the position of the virtual graphics information will also cause the user's eyesight to decrease and the head to be blurred. dizziness headache etc.
