Interaction Models for Multi-Display Slideshows


We present an investigation of interaction models for slideshow applications in a multi-display
environment. Three models are examined: Direct Manipulation, Billiard Ball, and Flow. These
concepts can be demonstrated by the ModSlideShow prototype, which is designed as a configurable
modular display system where each display unit communicates with its neighbors and fundamental
operations that act locally can be composed to support the higher level interaction models. We also
describe the gesture input scheme, animation feedback, and other enhancements.
