Past Research

Dynamic Focus Augmented Reality Display Addresses fundamental limitations of near eye displays including limited field of view, low angular resolution, and fixed accommodative state. Proposes hybrid hardware using see-through deformable membrane mirrors to provide wide FOV and accommodative cues, addressing Vergence-Accommodation Conflict.

Immersive Learning from 3D Reconstruction Investigates 3D reconstruction of room-sized dynamic scenes with higher quality and fidelity. Enables immersive learning of rare situations through post-event, annotated virtual reality experiences for emergency medical procedures.

Low Latency Display Developing low latency tracking and display system for ultra-low latency, optical see-through augmented reality head mounted displays. Runs at high frame rate and performs in-display corrections.

Office of the Future Unified application of computer vision and computer graphics combining panoramic image display, tiled display systems, image-based modeling, and immersive environments for 3D tele-immersion capabilities.

3D Telepresence for Medical Consultation Develops permanent, portable, handheld 3D telepresence technologies for remote medical consultations. Addresses real time acquisition, novel view generation, network variability, and 3D depth cues.

Wall-to-Wall Telepresence Enabled visualization of large 3D models on multi-screen 2D display for telepresence. Experimented with reconstructed models and dense datasets.

Multi-view Teleconferencing Two-site teleconferencing system supporting multiple people per site while maintaining gaze awareness. Provides unique views of remote sites to each local participant.

Ultrasound/Medical Augmented Reality Develops system allowing physicians to see inside patients using augmented reality. Combines ultrasound echography, laparoscopic range imaging, video see-through HMD, and graphics.

Pixel-Planes & PixelFlow Explores computer architectures for 3D graphics since 1980. Focuses on image-based rendering with goal of high-performance graphics engine using images as principal rendering primitive.

3D Laparoscopic Visualization Three-dimensional visualization system for laparoscopic surgical procedures. Uses 3D visualization, depth extraction, six degree-of-freedom tracking to display merged real and synthetic images.

Wide-Area Tracking Develops wide-area systems for 6D tracking of heads, limbs, and hand-held devices. Provides precise position and orientation information for head-mounted displays.

Image-Based Rendering Investigates alternative approach representing complex 3D environments with image sets containing depth information. Develops algorithms to produce new images from viewpoints not in original image set.

Telecollaboration Multi-site, multi-disciplinary project developing distributed collaborative design environment. Includes shared virtual environment software, collaborative VR, and interaction tools.
