Abstract: In embodiments, methods and systems are presented for physical interaction with computer-mediated information. A movable display module (including a touch screen monitor, CPU, absolute encoder and other sensors, and wireless network connection) is mounted on and can be moved along rails. The rails serve four purposes relating to the movable display module: 1) to provide DC power and/or data through the rails to the equipment; 2) to act as a rack gear for absolute encoding of physical position; 3) to provide physical support; 4) to act as guide tracks. As the display module slides along the rails, a computer program receives positional and other sensor data. The program maps the sensor data to programmatic content, and presents said content on the display module or on other displays or in external effects such as lights or robotics. The entire system is designed for reliability, affordability, and ease of mass production.
