The document discusses touchless interactive screen technology that uses pointscreen and gesture recognition. It allows users to control and navigate screens through gestures without touching the screen. The technology works using electric field sensing and capacitive sensing to detect hand motions in front of the screen. A Thracker device is a low-cost hardware system that can track hand gestures for interactive applications like zooming and scrolling on screens. Potential applications of this touchless interaction technology include interactive displays, medical devices, and future interfaces for devices like phones.
