This document discusses large multi-touch displays and their technical details. It covers various touch input technologies like touchscreens, touchpads, and Wacom tablets. It also discusses multi-touch technologies like FTIR, DI, LLP, and DSI. Examples of multi-touch displays are given, including The Box, The Tabletop, and MTMini. Common multi-touch gestures like tap, drag, rotate, scale, and zoom are also listed. The document provides information on software protocols, trackers, and libraries for processing multi-touch input.
