Method and system for visual processing human-machine interactive projection based on Android

Abstract

The invention discloses a method for visual processing human-machine interactive projection based on Android. The method comprises the following steps of enabling Android equipment to access into a projector through an HDMI (high-definition multimedia interface), and enabling the projector to project an Android interface onto a plane in real-time and high-definition ways; enabling embedded visual processing equipment to collect an image of a finger on a screen in real time, and finding the contour of a hot spot; filtering to obtain the finger coordinate of the effective operation; enabling the embedded visual processing equipment to access into the Android equipment through an USB (universal serial bus) interface; enabling an USB response function to process the finger coordinate obtained by the embedded visual processing equipment in real time, so as to operate an operation interface of the Android equipment in real time. The method and the system have the advantages that the operation disengaging from a host end is realized, the operation is easy, convenient and free, the physical operation sense is strong, and the like.

Description

Technical field [0001] The present invention relates to the field of human-computer interaction, in particular to an Android-based visual processing human-computer interaction projection method and system. Background technique [0002] There are two trends in the current technological society, the popularization of the Android platform and the increasing demand for projection image technology. Android is a free and open source operating system based on Linux, mainly used in mobile devices, such as smart phones and tablets. Because the portability of Android system devices is destined to have smaller screens and poor experience, it is necessary to use projection technology to project the interface of the Android device during work or entertainment. At the same time, people will control the Android operating system through embedded vision processing human gestures This system will greatly facilitate people’s work and life, and will be a revolutionary innovation. [0003] Nowadays, ...

AI Technical Summary

Problems solved by technology

Therefore, the traditional projection display device does not have the rich functions similar to PDA.

[0004] In terms of mobile phone projection, although there are products that directly embed the projection lens into the mobile phone, there are still shortcomings such as poor projection quality, lack of integration of existing projection resources, and lack of adaptability.
