Speaker: Emily Cooper, Post-Doctoral Researcher, Stanford University
Title: Is Stereo Vision Optimized for our Natural Environment?
Abstract: Many aspects of visual perception are based on regularities in the natural environment. A long-standing but untested theory has proposed that an aspect of binocular vision -- where so-called corresponding points are in the two retinas -- is adapted to the natural environment. This presentation describes a set of experiments that examined this theory. First, we measured whether binocular vision is best near the ground plane. We found, contrary to previous claims, that binocular vision is poorly adapted to the ground plane. In particular, we found that the region of best depth-perception from stereopsis is curved rather than flat. Next we asked if there are patterns in the 3D visual environment for which the curvature is adaptive. To answer this question, we constructed a unique mobile device that simultaneously measures binocular fixations and the 3D-scene layout. Subjects performed normal everyday activities, such as preparing a meal or walking through a park, while we measured where they were looking (including how far away they were looking) and the 3D-scene around them. The resulting data suggests that the region of best binocular vision is indeed well-adapted to the complex patterns of visual input experienced by humans engaged in everyday activities. The presentation includes several 3D demos of data from the mobile tracking device; analglyph (red/cyan) glasses will be provided to the attendees for viewing the demos.

Speaker: Francis MacDougall, Senior Director, Gesture Technology, Qualcomm
Title: Touchless Gestures Go Mainstream
Abstract: Touch-free gestures are moving from the world of Xbox 360 Kinect games into mainstream devices including mobile phones, tablets, laptops, digital cameras and TVs. This talk reviews recently released products that incorporate gesture control and contrasts the various implementations of gesture control in each product. These initial products are starting to define a "gesture vocabulary" that could allow touch-free gestures to be ubiquitous across a wide range of devices. However, there is a danger of having conflicting gesture implementations on different devices that could cause consumer confusion and constrain the potential market. The talk also discusses the various technologies for detecting gestures as well as the leading use-cases, power-consumption issues, and complementary technologies that typify the next-generation user-interfaces enabled by gestures.
Speaker Biography: Francis MacDougall founded GestureTek in 1986 and was its CTO until its technologies, patents and engineering team were acquired by Qualcomm in June of 2011. Francis is now Senior Director, Gesture Technology at Qualcomm and leads the effort to release gesture technologies on Qualcomm platforms including the Snapdragon chip targeting smartphones, tablets and TVs. Francis holds several fundamental patents using both 2D and 3D sensors and tracking techniques in the gesture space and has licensed these patents to Sony and Microsoft for their use in game console platforms. His team's software runs on tens of millions of devices worldwide.

Title: What You Missed In Boston: SID Display Week 2012 Reported by a Professional Journalist & Technologist
Abstract: If you weren't able to make the cross-country trip to Boston for SID Display Week 2012 last month, here's your opportunity to catch up on much of what you missed. SID Senior Member and Information Display Contributing Editor Alfred Poor will provide a guided tour of Display Week 2012, covering many of the highlights from the Exhibit Hall to the Symposium. Alfred's talk will include a discussion of some of the Display of the Year and Best of Show award winners. Among the winners was a 55-inch 4K LCD TV from AU Optronics, an e-reader using Qualcomm's Mirasol MEMS technology, the Quantum-Dot Enhancement Film (QDEF) from Nanosys that promises to lower the cost and improve the performance of LED backlights for LCD panels, the impressive 55-inch OLED televisions from LG and Samsung (which have several substantial design differences), and eye-tracking technologies for large-format stereoscopic 3D displays and active-matrix OLED microdisplays. You'll even hear about some of the intriguing new technologies that were on display at Display Week's new and wildly popular "Innovation Zone" (the I-Zone). The talk will also cover important trends, such as the move from aSi and LTPS backplanes to the use of metal oxides such as IGZO. The newer technology offers electron mobility between the two other solutions, with the advantage that it may scale better than p-Si for very large screens, although some challenges remain. Come hear about other advances, ranging from touch-screen technology to thin-substrate glass that can support roll-to-roll continuous processing. SID Display Week 2012 was filled with energy and information, and so will be this seminar. Don't miss it!

Speaker: Gary Mandle, Senior Product Manager, Sony Electronics
Title: Display Technologies Used for Film and Video Production
Abstract: Since the inception of television entertainment, only one primary display technology has been used in media-production applications: the cathode-ray tube. For almost 75 years, CRT technology has been the only acceptable means of viewing and mastering images for theatrical feature-film and television broadcasting. However, CRT devices are rapidly becoming unproduceable due to economic and environmental issues. While new technologies are now being used to display content in these applications, not all of the new technologies have been able to match the performance of CRTs. Even today, many production companies are still using CRT displays, and film creators are just now starting to feel comfortable with electronic acquisition and display.
This presentation will describe the applications and requirements for displays used for entertainment-media production. Using the latest Sony professional monitors as an example, the advantages and weaknesses of using OLEDs in these applications will be covered, along with OLED operation, performance, and construction. Other (future) display technologies currently under development will also be described. The presentation will conclude with a demonstration and side-by-side comparison between reference displays using CRT, LCD and OLED technologies.
Speaker Biography: Gary Mandle has worked in the Sony Gary Mandle PhotoProfessional Solutions Group for more than 27 years doing development and marketing of new display products. The technologies on which he has worked include CRT, SXRD (LCoS), LCD, and now OLED. His current focus is on Sony's OLED products intended for video & film production and post-production applications. Gary has written several journal articles and papers, including an article on monitor calibration that appeared in the April 2012 SMPTE Motion Imaging Journal. Gary's other work areas include the design of camera image-stabilization systems, including the invention of the semiconductor-based stabilizer system called "Steady Shot" that is used in most Sony-branded cameras, and CCD-sensor development where he holds multiple patents on processes for increasing imager dynamic range.

Title: Technology Transfer from Displays to Lighting
Abstract: The pace of technology development in the lighting industry has accelerated ten-fold. Over 90% of the products on view at leading lighting fairs are based on LED lights. But most of the products that have emerged so far are more energy efficient replacements of traditional technology with similar form and function. The opportunities to change the way lighting is used include:
- Large area lighting sources - thin, flexible, transparent
- Smart lighting - wireless digital controls
- Color control - multiple primaries with separate drive circuits
- Broadband communications
- Evolving lifestyles
Similar issues have been addressed in the display industry and there are clear opportunities for technology transfer. For example, the battle between LED-LCDs and OLEDs in large TVs may be replayed in lighting. In reverse, the rapid gains in the efficiency of LED and OLED sources for lighting applications may result in lower power consumption and longer battery life for displays.
