TLDR
In this article, the authors described a system for processing touch inputs with respect to a multipoint sensing device and identifying at least one multipoint gesture based on the data from the multi-point sensing device.
Abstract
Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

Multi-touch gesture dictionary

TL;DR: A multi-touch gesture dictionary can include a plurality of entries, each corresponding to a particular chord as mentioned in this paper, and gestures formed from the chord and the motions associated with the chord.
Patent

Touch panel system and method for distinguishing multiple touch inputs

TL;DR: In this paper, a touch panel system and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined, which can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive touch inputs.
