TouchTokens - Guiding Touch Patterns with Passive Tokens

Explore a 20-minute conference talk from the CHI '16 ACM Conference on Human Factors in Computing Systems that introduces TouchTokens, a novel approach to combining tangible and gestural input on multi-touch surfaces. Delve into the research behind passive tokens that guide touch patterns, including a formative user study analyzing grasp strategies and the development of notched tokens to improve pattern recognition. Learn about the high-accuracy classification algorithm designed for these patterns and its potential applications in creating rich touch input vocabularies for command triggers and parameter controls. Gain insights into the design process, experimental findings, and practical implementations of TouchTokens, including limitations and available libraries for TUIO and Android platforms.
