(Philip Lelyveld comment: two 3D exhibits described below)
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.”
A preview video of the SIGGRAPH 2011 Emerging Technologies program is available.

Volumetric Display Based on Vibrating Mylar Beam Splitter and LED Backlit LCD
Lanny Smoot, Quinn Smithwick, and Daniel Reetz; Disney Research
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
Hidei Kimura and Akira Asano, Burton Inc.; Issei Fujishiro and Ayaka Nakatani; Keio University
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.
