LCD Multitouch Display in Cardboard Box

Overview

The project illustrates the use of some plain paper and cardboard box to create a multitouch display that also employs the use of LCD.

Explanation

The device makes it fun to build tangible computer interfaces with interactive features out of cheaper components. The component required to build the project include an LCD that can be torn apart, a box, 60W bulb light source, a camera, some film negatives, plexan glass, and all the needed cables. The construction starts by disassembling the LCD and removing the backlight along with any non-translucent material. The box should be able to hold the display, camera, and light while the camera needs to be modified to make it sensitive only to IR before making an IR pen. This will produce some advanced IR projections.

By running the Config.bat, the TouchLib can be installed while adjusting the sliders to only read the correct blobs or IR light. The calibration is done by hitting the Enter and finally ending with ESC to save. This will give way to running any TouchLib applications and Clients. The light tubes can be used to light up the display since the LCD use Plexiglas.
