Multitouch Controller

 

Amanda Ghassaei (previously featured on Arduino Blog with Glitchbox and Vocal Effect box ) published the instructions to build an Arduino-powered infrared touchscreen / coffee-table interface that she’s been using to control various music and graphics applications on her computer.

Touché with Arduino

Friday, June 1st, 2012

Touché is a capacitive-sensing technology, developed by Walt Disney Research, which aims at providing touch and gesture sensitivity to a great variety of objects. From this research paper:

The technology is  scalable, i.e., the same sensor is equally effective for a pencil, a doorknob, a mobile phone or a table. Gesture recognition also scales with objects: a Touché enhanced doorknob can capture the configuration of fingers touching it, while a table can track the posture of the entire user.
The technique behind Touché is known as Swept Frequency Capacitive Sensing (SFCS): at a glance, by monitoring the capacitive response of an object over a specific range of frequencies (instead of a single one), it is possible to infer about its interaction with the outside world.
In his blog, Dzl describes his personal approach toward the development of a system capable to emulate Touché’s behavior with Arduino. Currently, the project is still in a early stage, but improvements and further developments are expected soon.

Possible low-end solution for multi-touch surfaces based on Arduino Mega:

So i’ve been working on this project for a while now as part of my thesis and independently and work is still continuing. So just an overview the project is a multi-touch and multi-modal input sensor that can be utilised behind traditional LCD panels utilising a new method to detect inputs. By using a large IR sensor array consisting of 128 sensors behind the LCD panel and IR light source in front of the Panel we are able to augment the display with the ability to sense a variety of objects near or on the surface; including fingers tips and hands and thus permitting us to enable multi-touch interaction. The inherent nature of the senors allows us to create a low cost high fidelity image sensor allowing us to take advantage of optical sensing which also allows other physical items to be detected, and thus permits us to develop multi-modal interaction schemas.

Amazingly done with Processing and a simple Arduino Mega board.
