Abstract
This dissertation introduces haptic holography, a combination of computational modeling and multimodal spatial display, as an early computationalplastic In this work, we combine various holographic displays with a force feedback device to image free-standing material surfaces with programmatically prescribed behavior. We present three implementations, Touch, Lathe, and Poke, each named for the primitive functional affordance it offers. In Touch, we present static holographic images of simple geometry, reconstructed in front of the hologram plane (in the viewer's space), and precisely co-located with a force model of the same geometry. These images can be visually inspected and haptically explored using a hand-held interface. In Lathe, we again display holo-haptic images of simple geometry, this time allowing those images to be reshaped by haptic interaction in a dynamic but constrained manner. Finally in Poke, we present a holo-haptic image that permits arbitrary reshaping of its reconstructed surface. As supporting technology, we offer a new technique for incrementally computing and locally updating interference-modeled holographic fringe patterns. This technique permits electronic holograms to be updated arbitrarily and interactively, marking a long-held goal in display holography. As a broader contribution, we offer a new behavior-based spatial framework, based on both perception and action, for informing the design of spatial interactive systems.
