What are the possible ways of making a multitouch device?
There are many ways to create multitouch devices. While commercial technologies tend to rely on more expensive approaches like capacitive sensing, the techniques widley used at NUIGroup are considered optical, or vision techniques. To find the four main do-it-yourself techniques (FTIR, DI, LLP, DSI) used on the forum, please see Getting Started With Multitouch. There’s also an illustration on the forum which shows different kinds of multitouch systems.
