The place to have been this past January 29th through 31st was San Jose for the 2007 Stereoscopic Displays and Applications conference. Held at the San Jose McEnery Convention Center, San Jose, California as part of the 19th Electronic Imaging: Science & Technology Symposium - organized jointly by the Society for Imaging Science and Technology (IS&T) and the International Society of Optical Engineering (SPIE). Check the website: www.stereoscopic.org/2007 to see what you missed. The Stereoscopic Displays & Applications conference is the largest and longest running technical stereoscopic imaging conference worldwide and an excellent opportunity to meet with others working in this unique field. |
While some form of the Stereoscopic Display conference has been around for over two dozen years, I have only been attending bits and pieces for the past ten. In the past I have always tried to get there for at least the display demonstration session (which is usually free,) [A fee to attend this session applies from 2008] the stereoscopic video 3D theater session presentation and the keynote address if possible. This was the first year that I could take advantage of the invitation to cover the entire event for Stereo World. Past conferences have been covered by Steve Berezin (Stereo World V29 #4) and Ray Zone (Stereo World V31 #5)
Press credentials certainly beat the several hundred dollar entrance fee, but who can put a price on a glimpse into the future? This is where there is the greatest concentration of information about stereoscopic displays and their future. The conference once was held in conjunction with the Photonics West show, but the crowd grew too large and now the display conference is being held the week following Photonics West, which features an interesting trade floor of its own.
The day prior to the conference, there was an educational short course held that requires an additional fee. This year the course was Stereoscopic Display Application Issues. The conference itself is nicely divided into a dozen sessions with several presentations under each session and the time moves by quickly. Monday morning saw session 1 "Stereoscopic Display Applications" and session 2 "Medical Applications of Stereoscopy." After lunch session 3 was "Stereoscopic Image Processing and Intermediate View Reconstruction," session 4 examined "Stereoscopic Human Factors." Another break and it was time for the 3-D Theater. Unfortunately there was a slight problem with the sound during most of the presentations. But this misfortune turned out to have a silver lining, since many of the 3-D videos were replayed during the breaks of the remainder of the conference.

Following the theater session, the majority of attendees walked to the nearby BoTown Chinese Restaurant for an annual tradition - the SD&A dinner, a no-host informal affair which gives you a chance to make new friends and discuss the day's events.
The 3D Consortium showcased stereoscopic products from member companies. David Mark from Mark Resources demonstrated a 22 inch LCD autostereoscopic display monitor with a diagonal parallax barrier creating seven views for 3-D viewing, and a 60 inch diagonal full-color 3-D back-lit transparency print with 30kx40k resolution showing a collection of fluorescent minerals. For3D showed three stereoscopic monitors from Pavonine of South Korea. Stereo by Lawrence Kaufman (wall-eye stereopair)
It was back to Wheatstone for Imprint Interactive Technology of Seattle,with their digital stereoscope system based on two LCD panels and mirrors with a VR demonstration application. Stereo by Lawrence Kaufman (wall-eye stereopair)
Day two and day three began with plenary presentations which were open to the entire Electronic Imaging symposium. In fact the "technical program" for the symposium is a thick 216 pages - larger than many small town phone books. The plenary presentations were naturally held in a very crowded large ballroom. On day two Brian A. Wandell from Stanford University discussed "Development and Plasticity in Visual Cortex."
Even more interesting were the two presentations on day three, first Francois Blais, National Research Council of Canada presented "More than a Poplar Plank: The Shape and Subtle Colors of the Masterpiece 'Mona Lisa' by Leonardo." This was an in-depth look at a scientific examination of the Mona Lisa, including a 3-D digitization (3D imaging) of the painting. The Second session was "Space Exploration, Imaging Technology, and the Development of a Virtual Presence in Space" by Eric M. De Jong, Principle Investigator, Solar System Visualization (SSV) Project. This was a very interesting up to the minute presentation on the history of Space Exploration and included the current stereo visualization. I had heard De Jong on at least two previous occasions once at a Society of Motion Picture and Television Engineers (SMPTE) meeting and at NASA's Jet Propulsion Laboratory (JPL). At the two previous talks, the presentation had included stereo imaging, so as interesting as this was, it seemed a little flat. De Jong was a co-author of "NASA's STEREO Mission" (Stereo World V32 #1) It was nice also to later see De Jong sitting in the day 3 sessions.
More Stereo Display Sessions
Day two included session 5 "Stereoscopy on Mobile Devices," session 6 "Multiview Content," Session 7 "Autostereoscopic Displays," and session 8 "Stereoscopic Developments," before moving into the SD&A Demonstration Session. The Demo session, as I stated earlier, is one of my favorite parts of the conference. Over the years I have seen many amazing items. Some are now currently available, some are still being developed, others have come and gone and others have never been heard of again. The Demos have become so popular that they now include the entire EI conference symposium and the papers are also posted in the room. A partial list of presenters can be found later in this article and at www.stereoscopic.org/2007.
Day three included session 9 "Crosstalk in Stereoscopic and Autosteroscopic Displays," a panel discussion on "3D in the Home: How Close are We?," session 10 "Stereoscopic Video," Session 11 was the Keynote Presentation. The day and the conference ended with session 12 "Integral 3D Displays." Session 13 "Virtual Environments: Implementation" (which included "Three-dimensional cameras on the International Space Station") and session 14 "Virtual Environments: The Experience."

Live microstereoscopic video was displayed on a Planar StereoMirror stereoscopic display. Stereo by Lawrence Kaufman (wall-eye stereopair)
The discussion forum "3D in the Home: How Close are We?" moderated by Lenny Lipton, CTO, Real D was a fun and lively discussion. The panel included Brett Bryars, United States Display Consortium; Art Berman, Analyst, Insight Media; Mark Fihn, Publisher, Veritas et Visus/3rd Dimension Newsletter and Steven L. Smith, CEO, VRex Inc. The panel shared their thoughts and then opened it up to questions from the audience, finishing with their predictions for when we would have 3-D in the home. Mark Fihn had opened by saying that even though he has television devices in his home, he and his wife do not watch regular TV. His prediction was 2010 for "his" home. Lipton's optimistic prediction "this year" was based on the fact that he is an avid reader of Popular Science and anything they discuss is doomed. But since they have not discussed 3-D TV, he feels very confident that it will roll out soon.
The Keynote Presentation was "A Look at the Past and Future of Stereoscopic Displays Through a (Liquid) Crystal Ball" by James Ferguson of Ferguson Patent Properties was more of a look back at the beginning of liquid crystal displays than the future. But James Ferguson was the single most important individual to lead this discussion. He holds 130 U.S. patents and his inventions form the foundation of the multi-billion dollar liquid crystal display industry.
Andrew Woods discussed the project he lead testing a wide range of consumer DLP projectors to determine their level of compatibility with stereoscopic display using liquid crystal shutter (LCS) 3-D glasses. At the end of the project they had tested 44 consumer grade Single-chip DLP projectors. They found fifteen that work well at up to 85Hz stereo in VGA mode. See his website for details: www.3dmovielist.com/projectors.html.

Jason Goodman, CEO 21st Century 3D announced their new stereoscopic camera and solid state recording systems. The 3DVX3.5 adds new features, refines ergonomics and redefines the state of the art as the world's smallest and lightest high definition 3-D camera-recorder. The 3DVX-H is a modular hyperstereoscopic camera system that allows for stunning photography of distant subjects while maintaining a strong stereoscopic 3-D effect. With ordinary camera separation, discernible stereoscopy diminishes as the camera's distance from the subject increases. The 3DVX-H compensates for this by allowing users to increase the intraocular distance to as much as three feet or more as highlighted in Stereo World Vol. 32 No.5, page 28. Jason demonstrated the 3DVX3.5 High-Definition stereoscopic video camera and showed some sample footage from the camera using a Sharp AL3D autostereoscopic laptop. For more information, see www.21stcentury3d.com.
ColorLink, a leading supplier of polarization and color management optics for the consumer electronics industry, announced the release of ALPSTM (Achromatic Linear Polarization Switch), a solid state switchable polarizer for stereoscopic 3-D projection systems. The product was launched at the 2007 Stereoscopic Displays and Applications Conference and was used as a key component of one of the conference's stereoscopic projection systems using ALPS to showcase the conference's 3-D content. ColorLink's CTO, Gary Sharp, presented a technical paper on ALPS. ColorLink has been doing some amazing and new things in 3-D, so it was no surprise that they were purchased by Real D shortly after the conference.
