AR Pueblo board game

Abstract

This paper considers a new tangible interface for vision-based Augmented Reality (AR) systems. Tangible AR interfaces provide users seamless interaction with virtual objects in AR systems but with the restriction of user's motions. A new tangible AR interface is designed to overcome this limitation. Two hexahedral objects are attached together to create the new tangible AR interface. The shape of the new tangible AR interface removes the restriction of user's motions in existing tangible AR interfaces. Users can move and rotate the new interface freely to manipulate virtual objects in AR environment. This improvement is useful for applications that require unrestricted rotation motions of virtual objects. The Pueblo board game is developed to demonstrate the usability of the new tangible AR interface. © IFIP International Federation for Information Processing 2005.
