Guest Editors´ Introduction: Interacting with Digital Tabletops

A digital tabletop is sufficiently different from the standard desktop computer in that it invites researchers to challenge traditional perspectives on human-computer interaction, such as rethinking the use of a computer as a solitary act, the activities people do with computers, the types of social interactions that can be part of digital interactions, and how the interplay between digital and social needs can be supported. This special issue on digital tabletops provides a sample of the research being conducted in this domain.
