Problems solved by technology

The main problem is that the volume of the equipment has been greatly increased, which has requirements for the use of space, which weakens the portability of the portable projection itself, and at the same time cannot support three-dimensional gesture operations in space.

Abstract

The invention discloses an information processing device and method. The information processing device comprises a first light source part used for emitting a first light ray, a first light conversion part arranged between the first light source part and a projection surface and used for enabling the first light ray to form a second light ray after passing through the first light conversion part, an image acquisition part and a processing part, wherein the second light ray can form a first invisible image with preset patterns on the projection surface; the image acquisition part is provided with an acquisition region, the projection surface is positioned in the acquisition region, when a target object enters the acquisition region, the image acquisition part is used for acquiring a second invisible image of the second light ray, formed on the target object; and the processing part is connected with the image acquisition part and used for processing the second image to obtain a space position parameter of the target object relative to the information processing device.

Description

technical field [0001] The present invention relates to an information processing device and method, and more particularly, to an information processing device and method capable of user interaction. Background technique [0002] At present, the application of miniature projection equipment is more and more extensive. In particular, the advent of laser-scanning projection, which allows direct imaging in arbitrary planes without prior adjustment of the focus, has received special attention. Pico-projectors can be used as display devices, but how to provide corresponding interactions has always been an unresolved problem. [0003] Existing solutions mainly include the following two types. [0004] Solution 1: Use the camera to detect user gestures. Because of the inherent defects of using the camera image processing algorithm alone, the stability is not high, the system consumes a lot, and the gesture judgment has a recognition rate problem, especially the three-dimensional...
