Survey and Review of Input Libraries, Frameworks, and Toolkits for Interactive Surfaces and Recommendations for the Squidy Interaction Library

This diploma thesis presents a survey and review of 28 input libraries, frameworks, and toolkits. They originate from the domains multi-touch interaction, multi-modal interaction, tangible interaction and augmented and virtual reality. The main perspective is software engineering. Out of the set of software platforms the Squidy Interaction Library is chosen as basis for the Curve project, an interactive desk featuring a curved multi-touch surface. The software architecture of Squidy is discussed and compared with the architecture of DirectShow, a multimedia subsystem of Microsoft Windows. A number of improvements for further developments of Squidy are recommended and described in detail. One improvement has been exemplarily implemented.
