Abstract

Nowadays, the devices have the role to be user-friendly with the touch interfaces. In this paper it is presented an interactive touching device fully supported in LED technology. This is achieved through the use of an array of LEDs where each one works as a light emitter and as a sensor. The implementation uses a microcontroller to control the LED operation. Also it is proposed a new LED unit matrix configuration that avoids the use of an external light source to detect any touch. This new architecture only needs two microcontroller input/output to each row plus column which provides a user-friendly interactive contactless interface. Also it is explained how to aggregate these unit modules into a bigger LED display panel, reducing implementation costs.
