Ultra-Tangibles: Creating Movable Tangible Objects on Interactive Tables

Tangible User Interfaces combined with interactive surfaces allow users to handle a physical object to manipulate digital content. However, creating the reverse effect, having digital content manipulate a tangible object, is a more challenging task. We present a new approach to this problem, using ultrasound-based air pressure waves to move multiple tangible objects, independently, around an interactive surface. We describe the technical background, design, implementation, and test cases for such a system. We conclude by discussing practical uses of our system, Ultra-Tangibles, in the creation of new tangible user interfaces.
