An Evaluation of Hybrid Stacking on Interactive Tabletops

Abstract

Stacking is a common practice of organizing documents in the physical world. With the recent advent of interactive tabletops, physical documents can now coexist with digital documents on the same surface. As a result, systems were developed and studied which allow piling of both types of documents with the physical documents being placed on top of the digital ones. In this paper, we study the concept of true hybrid stacking, allowing users to stack both types of documents in an arbitrary order using a hybrid tabletop system called StackTop. We discuss the results and derive implications for future hybrid tabletop systems with stacking support.
