The SIGGRAPH Emerging Technologies program is home to the latest developments in technology, including haptics, displays, robotics, and artificial intelligence. This year will feature 23 of the latest innovations selected by a jury of industry experts from more than 100 submissions. Topics range from displays and input devices to collaborative environments. SIGGRAPH 2011 takes place 7-11 August at the Vancouver Convention Centre.

“The SIGGRAPH Emerging Technologies program is unique in its interactive approach that allows people to experience the most cutting-edge developments first-hand,” said Cole Krumbholz, SIGGRAPH 2011 Emerging Technologies Chair and co-founder of Koduco Games. “This year, conference attendees will experience the latest achievements from industry and university research labs.”

Volumetric Display Based on Vibrating Mylar Beam Splitter and LED Backlit LCD

This new volumetric display produces full-color, high-spatial-resolution aerial images in front of the apparatus. It is based on a new optical element: the large, tunable-resonance, edge-driven, varifocal beam splitter.

This new display technology uses a circular Mylar beam splitter and adds a tension-adjusting metal hoop pressed against its surface. The beam splitter is adjusted, with high Q, to a specific resonance frequency. Three rim-mounted impulse drivers apply low-amplitude sinusoldal drive. Due to the high Q, the diaphram’s sympathetic vibration is large. The beam splitter folds the optical path, and the system includes a fixed-curvature concave mirror to create real images that appear out in front of the apparatus.

It produces high-quality 3D images that occupy a one-third-meter cube 1/3 meter out in front of the apparatus. The image is viewable over a 30-degree viewing angle.

Potential Future Use: Advancements in 3D displays will impact many fields from medical research to gaming.

True 3D Display

This research team was the first to use laser-plasma technology for a true-3D display device that allows users to draw 3D images in midair. Now the team has developed a much more compact and precise display, called SRV (Super Real Vision)-5000, based on advanced laser technology. One remarkable feature of the new device is its enhanced resolution: from 300 points per second to 50,000 points per second. It displays 3D objects more faithfully in real time and increases the range of possible applications.

Memorial Day weekend is the unofficial start of summer — picnics at the park, swimming at the beach and the latest 3D blockbuster movies coming soon to a theater near you.

There has been confusion about the affect of eye health from 3D viewing, which is not harmful. The Kentucky Optometric Association offers tips on how to minimize eye strain while watching movies and things to look for when viewing 3D that might signal an eye problem.

First, since 3D viewing is based on the eyes converging in front of or beyond the screen, viewing those images can potentially create eyestrain and headaches. Consumers can reduce the conflict by sitting at a greater distance from the screen.

Second, a viewer lacking binocular vision simply won’t see 3D. Although this doesn’t pose any problem viewing the screen, it serves as a vision screening that something is abnormal with the viewer’s binocular vision.

“That means 3D actually has a benefit,” said Dr. Joe Ellis, a doctor of optometry in Benton, Ky., and president of the American Optometric Association. “It can alert people to undetected vision disorders and eye diseases that, if caught early, are fully treatable.”

The KOA recommends seeing a doctor of optometry for further evaluation if consumers answer yes to any of the following questions:
• Is the 3D viewing experience not as vivid as it is for others watching the same picture?
• Do you experience eyestrain or headaches during or after viewing?
• Do you feel nauseous or dizzy during or after viewing?
• Are you more comfortable viewing 2D TV or movies instead of 3D TV or movies?
• Is it difficult for your eyes to adjust back to normal after watching 3D TV or movies?

About the Kentucky Optometric Association:
Doctors of optometry are located in 106 counties in Kentucky. They are highly qualified, trained doctors on the frontline of eye and vision care who examine, diagnose, treat and manage diseases and disorders of the eye. In addition to providing eye and vision care, optometrists play a major role in a patient’s overall health and well-being by detecting systemic diseases such as diabetes and hypertension.

Prior to optometry school, optometrists typically complete four years of undergraduate study, culminating in a bachelor’s degree. Required undergraduate coursework for pre-optometry students is extensive and covers a wide variety of advanced health, science and mathematics. Optometry school consists of four years of post-graduate, doctoral study concentrating on both the eye and systemic health. In addition to their formal training, doctors of optometry must undergo annual continuing education to stay current on the latest standards of care.
