SSTT Touch: SSTT Touch Multitouch Augmented Reality

Using the hand for interaction has been ignored for a while in general computing and in AR. SSTT Touch is a an approach to enable interaction spatially registered with an AR marker. The objective is to not use any additional input devices for interaction. The high performance AR tracking library SSTT core enables the tracking of multiple touches around the edges of a tracking target with a minimum of computational cost.

SSTT Mobile is a straight port of SSTT library to the Windows Mobile platform. The SSTT library is inherently multi-platform capable and this port underlines the commitment to support as many platforms as possible. As of January 2009 runs at approx. 1-5fps with tracking and 15fps without on this Samsung Omnia phone.

SSTT - Simplified Spatial Target Tracker is a computer vision based tracking library for Augmented and Mixed Reality applications. The basic variant implements a marker based approach with a minimal set of constraints. Unlike similar libraries such as ARToolKit or the marker based StudierStube the approach of SSTT does not require thick black borders. The SSTT tracking algorithm automatically qualifies company logos or even images in books immediately as tracking targets. The following video illustrates the tracking performance.
