The camera is connected to a computer and a tracking application uses the camera image to track and create touch coordinates. Multi Touch Screen Software for Interactive Digital Signage Multi touch screen software for effective interactive digital signage solutions. ppt into high-resolution images which then can be processed or edited via touch gestures.

The projector is connected to a computer in order to display the software on the touch surface. Our multi-touch software automatically converts. In order to separate the objects being tracked from the visual display, a camera can be modified to only see the infrared spectrum of light (by removing the infrared filter and replacing it with a visible light or bandpass filter) this cuts out the visual image from being seen by the camera and allows the camera to only see infrared light that illuminates the objects/fingers on the touch surface. Since most systems have a visual feedback system where an image from a projector or LCD is projected or placed below the touch surface (the MTmini does not), it is important that the camera does not see this image when tracking objects/fingers on the display. Infrared light is used to distinguish between a visual image on the touch surface and the objects/fingers being tracked.

Infrared Camera (or other optical sensor)Īn infrared camera is pointed at the touch surface and detects when fingers/objects touch the surface.

MTmini, MTbiggie)Įach technique utilizes 3 main components:

Our focus will be on optical techniques since they are the easiest and most cost effective for the average person to create. There are capacitive, resistive, acoustic, and other non-traditional techniques. There are several ways to make a multitouch surface.
