A research team led by Susumu Tachi from the University of Tokyo has developed a rotating panoramic display that immerses viewers in a 3D video environment. The Telexistence Wide-angle Immersive STEReoscope, or TWISTER, is the worlds first full-color 360-degree 3D display that does not require viewers to wear special glasses, says professor Tachi, who has spent over 10 years researching and developing the device.
Inside the 1.2 meter (4 ft) tall, 2 meter (6.5 ft) wide cylindrical display are 50,000 LEDs arranged in columns. As the display rotates around the observers head at a speed of 1.6 revolutions per second, these specially arranged LED columns show a slightly different image to each of the observers eyes, thus creating the illusion of a 3D image. In other words, TWISTER tricks the eye by exploiting what is known as binocular parallax the apparent difference in position of an object as seen separately by the left eye and the right eye.
