Simple Multi-Touch Toolkit


Erik Paluka, Zachary Cook, Mark Hancock, Christopher Collins


While multi-touch computing becomes more common, there comes a requirement for students to learn how to create software for multi-touch environments.  Although, there are many powerful toolkits that exist already, they require a strong programming background and thus become difficult to integrate into fast-paced human-computer interaction (HCI) courses or for non-CS students to use.  Researchers at the University of Ontario Institute of Technology (UOIT) and the University of Waterloo (UW) have developed a toolkit with a simplified API called the Simple Multi-Touch Toolkit (SMT).

Based around the concept of touch-enabled zones, SMT is built as a library for the popular processing platform or as a standalone Java library.  By integrating with Processing’s simplified syntax, SMT makes prototyping multi-touch applications fast and easy.   SMT natively supports TUIO and works on Windows Touch but also provides multi-touch simulator to support non-touch enabled environments.  While SMT was designed to support students and used in undergraduate HCI courses at both UOIT and UW in experimenting with multi-touch input, SurfNet researchers have also used SMT to develop several applications.
