Stereoscopic Display Application Issues
When correctly implemented, stereoscopic 3D video displays can provide significant benefits in many areas, including endoscopy and other
medical imaging, remote-control vehicles and telemanipulators, stereo 3D CAD, molecular modeling, 3D computer graphics, 3D visualization,
and video-based training. This course conveys a concrete understanding of basic principles and pitfalls that should be considered in
transitioning from 2D to 3D displays, and in testing for performance improvements. In addition to the traditional lecture sessions, there will be a
"workshop" session to demonstrate stereoscopic hardware and 3D imaging/display principles, emphasizing the key issues in an
ortho-stereoscopic video display setup, and showing video from a wide variety of applied stereoscopic imaging systems.
This course will enable you to:
- list critical human factors guidelines for stereoscopic display configuration & implementation
- calculate optimal camera focal length, separation, display size, and viewing distance to achieve a desired level of depth acuity
- calculate comfort limits for focus/fixation mismatch and on-screen parallax values, as a function of focal length, separation, convergence, display size, and viewing distance factors
- set up a large-screen stereo display system using AV equipment readily available at most conference sites, for slides and for full-motion video
- evaluate the trade-offs among currently available stereoscopic display technologies for your proposed applications
- list the often-overlooked side-benefits of stereoscopic displays that should be included in a cost/benefit analysis for proposed 3D applications
- avoid common pitfalls in designing tests to compare 2D vs. 3D displays
- calculate and demonstrate the distortions in perceived 3D space due to camera and display parameters
- design and set up an orthostereoscopic 3D imaging/display system
- understand the projective geometry involved in stereo modeling
- enumerate the problems, and the solutions, for converting stereoscopic video across video standards such as NTSC to PAL
- understand the trade-offs among currently available stereoscopic display system technologies and determine which will best match a particular application
