Problems solved by technology

[0004] However, at this stage, projection technologies such as ring screens that apply edge fusion technology can project a clear and bright image, but in many cases, users can only be in a passive audio-visual reception angle, and lack real-time interaction, especially touch. The immersive, flexible and changeable experience brought by interactive

Embodiment

[0033] The invention breaks the limitation that the projected image can only be a plane regular figure in the past, and uses a special optical lens to perform special transformations such as edge fusion on the ordinary plane image, and projects it on a hemispherical, spherical and other irregular-shaped screen to form A non-planar image. The edge fusion device overlaps the edges of the pictures projected by a group of projectors, and displays a whole picture without gaps, brighter, super large and high resolution through fusion technology.

[0034] Taking internal projection as an example, a high-lumen projector can be used to project the transformed image on the sphere, making the sphere look like a sci-fi crystal ball, which can attract the attention of visitors very well. Visitors can control the content played on the sphere through the multi-touch screen. The so-called multi-touch is an interactive method that allows users to use multiple fingers to control image applicat...

Abstract

The invention relates to a human-computer interaction system based on irregular screen multi-touch, comprising: interactive content specified playback device; video image transmission device; image projection device; multi-touch device; client command judging device; control terminal timeout The judging device; the command sending device of the control terminal; the image projecting device of the playback terminal; the image content display device. Compared with the prior art, the present invention breaks the limitation that the projected images in the past can only be flat and regular graphics, and can conveniently project various image contents on irregular screens such as hemispherical and spherical, so that the audience has Immersive experience and other advantages.

Description

technical field [0001] The invention relates to a human-computer interaction system, in particular to a multi-touch human-computer interaction system based on an irregular screen body. Background technique [0002] The current common projection technologies, whether it is front projection, rear projection, ceiling projection, or side projection, are all projection methods that a single projector can support. When used as a single unit, the projection effect of the front projection is poor, the exposed wiring affects the aesthetics of the environment, and the noise is relatively large. The disadvantage of rear projection is that the projection area is small, and it is only suitable for occasions where the environment is luxurious and the venue is wide. However, the more popular methods such as ceiling projection and side projection have shortcomings such as signal attenuation and inconvenient daily maintenance. Especially, the projector with side projection function places g...
