Portable mobile information security display system based on mental visual modulation

Abstract

The invention provides a portable mobile information security display system based on mental visual modulation. The system comprises a computer device used for realizing real-time projection processing and detection; a polarization device used for controlling a polarization direction; a multimedia device used for playing pictures or videos; glasses used for observing privacy information; a movable display board used for accepting projection information; and a camera device used for detecting the display board. The portable mobile information security display system can enable an authorized user to observe information with relatively high security level by wearing matched glasses on relatively private occasions, the other unauthorized users can only observe information with relatively low security level; and in addition, the portable mobile device provides more flexible and abundant modes for lecturers or showers, and limited information is transmitted just by standing in front of a screen depending on a limited screen together with simple gestures. The portable mobile information security display system breaks through the traditional conference mode, pays more attention to the security field while enriching the display modes and the information, and thus having a wide application prospect.

Description

technical field [0001] The invention relates to the fields of multimedia information display and multimedia information security, and in particular, relates to a portable and movable information security display system. Background technique [0002] In the traditional conference mode, the speaker stands in front of a screen, facing the audience, and only relies on the limited screen area to convey limited content information. If you want to make the displayed content more substituting, some speakers or exhibitors will add some gestures, but gestures are only an expression of the speaker’s emotions, and the sense of substitution cannot be effectively enhanced, and the displayed information still depends on the following screen content. Therefore, a movable display device that is separated from the original projection screen is designed, so that the speaker can take the device anywhere in the venue. Relying on this alone, it can be used as a powerful display auxiliary system...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the defects in the prior art, the object of the present invention is to provide a portable and movable information security display system based on psycho-visual modulation, which not only solves the limitations of traditional projection display, but also solves the problem of privacy protection in the field of multimedia information security
