This document discusses touchless technology, including touchless touch screens and monitors that can detect motion in 3D without requiring direct contact. It provides examples of technologies inspired by touchless interfaces shown in the film Minority Report, such as a screen that resembles the Nintendo Wii remote. The document also outlines several touchless input methods including eye tracking devices, gesture recognition solutions, and motion sensors that allow control through hand and finger movements in thin air. It speculates that future user interfaces may transform the human body itself into a virtual input device.
