Multitouch – How To
How To Make a Multitouch Surface
There are several ways to make a multitouch surface. There are capacitive, resistive, acoustic, and other non-traditional techniques. Our focus will be on optical techniques since they are the easiest and most cost effective for the average person to create. The most popular optical techniques are:
- Frustrated Total Internal Reflection (ie. Perceptive Pixels)
- Rear Diffused Illumination (ie. Microsoft Surface)
- Front Diffused Illumination (ie. MTmini, MTbiggie)
- Diffused Surface Illumination
- Laser Light Plane
- LED Light Plane
Optical Multitouch Techniques
Each technique utilizes 3 main components:
- Infrared Camera (or other optical sensor)
- Infrared light
- Visual Feedback (projector or LCD)
An infrared camera is pointed at the touch surface and detects when fingers/objects touch the surface.
