A feedback-controlled interface for treadmill locomotion in virtual environments
Lee Lichtenstein,James Barabas,Russell L. Woods,Eli Peli +3 more
- 01 Jan 2007
TL;DR: A feedback-controlled locomotion interface that allows the VE workstation to control the speed of the treadmill, based on the position of the user, which is compared to the self-propelled mode to measure the efficacy of each mode in maintaining constant subject position, subject control ofThe treadmill, and subject pulse rates.

Reconfigurable image projection holograms
TL;DR: The RIP technique improves on the image quality of conventional stereograms while affording similar efficient computation: it incorporates realistic computer graphic rendering or high-quality optical capture of a scene, and its basic multiply-and-accumulate op- erations are suitable for hardware implementation.
Real-time holographic video images with commodity PC hardware
TL;DR: The implementation of a new computational subsystem for the display is described, replacing custom computing hardware with commodity PC graphics chips, and using OpenGL, and first results of implementing the Reconfigurable Image Projection (RIP) method of computing high-quality holograms on this new system are presented.

- 12 Feb 2009
TL;DR: In this paper, a diffraction specific holographic stereogram algorithm was proposed for efficient parallelized vector implementation using OpenGL and Cg vertex/fragment shaders for lightfield reconstruction by holographic fringes.
Diffraction specific coherent panoramagrams of real scenes
TL;DR: In this article, the Diffraction Specific Coherent Panoramagram (DSPCP) is used to generate directionally-varying wavefront curvature, and can be computed at interactive rates using off-the-shelf graphics processors.
