Abstract

This paper introduces DisplayObjects, a rapid prototyping workbench that allows functional interfaces to be projected onto real 3D physical prototypes. DisplayObjects uses a Vicon motion capture system to track the location of physical models. 3D software renditions of the 3D physical model are then texture-mapped with interactive behavior and projected back onto the physical model to allow real- time interactions with the object. We discuss the implementation of the system, as well as a selection of one and two-handed interaction techniques for DisplayObjects. We conclude with a design case that comments on some of the early design experiences with the system.
