Смысл: The text explains the technical process of creating a head-tracking system that transforms a flat monitor into a pseudo-3D window by mathematically correcting perspective distortions based on the viewer's real-world position.
An exploration of using computer vision and homography to create a perspective-correct 3D effect on a 2D screen via headtracking.
Смысл: The text describes a DIY project to automate the rotation of a monitor/TV screen using a custom-made physical sensor and a C program, eliminating the need to manually enter commands to change screen orientation in Linux.
The author built a physical sensor using a lipstick tube and a ball bearing to automatically trigger Linux screen rotation commands when a monitor is physically turned.
Смысл: The main idea is to demonstrate a practical application of polarization physics to create a privacy screen by transferring the monitor's polarizing filter to a pair of glasses.
A step-by-step DIY guide on how to make a monitor invisible to everyone except the wearer of special polarizing glasses by removing the screen's filter.
Смысл: The main idea is to promote 3M's privacy screen technology by explaining its practical utility in preventing 'visual hacking,' its technical implementation via light-controlling optical films, and its role in overall information security and professional productivity.
3M Russia presents privacy screens that use optical film technology to restrict viewing angles, protecting sensitive data from onlookers in public and office settings.
