Multimodal Split View Tabletop Interaction Over Existing Applications

Abstract

While digital tables can be used with existing applications, they are typically limited by the one user per computer assumption of current operating systems. In this paper, we explore multimodal split view interaction - a tabletop whose surface is split into two adjacent projected views - that leverages how people can interact with three types of existing applications in this setting. Independent applications let people see and work on separate systems. Shared screens let people see a twinned view of a single user application. True groupware lets people work in parallel over large digital workspaces. Atop these, we add multimodal speech and gesture interaction capability to enhance interpersonal awareness during loosely coupled work.
