Glasses-Free 3D Display Re-adjusts via Six-Axis

Toshiba Mobile Display was reportedly showing a prototype self-adjusting 12.1-inch display at 3D Expo 2010 that provides a 3D image without the need for special, nerdy glasses. Using a six-axis accelerometer, the on-screen 3D object was mostly viewable at any angle-- viewers could look around the object by merely tilting the display.

As Toshiba pointed out at the show, naked-eye 3D displays have started to become widespread, however one of the current issues is that their viewing range can be a bit narrow. "So here, we assume that when a handheld 3D display is tilted, the viewer's head is always perpendicular to it," a Toshiba representative told DigInfo TV at the show. "By continually turning the normal viewing range of the display towards the user's head, we increase the viewing range virtually, by a factor of three. In other words, we've developed technology that increases the viewing angle from about 30 degrees to about 90 degrees."

According to Toshiba, the position of the viewer's head (and thus the viewing position) is determined by the tilt data provided by the display's six-axis acceleration sensor. Built-in software processes the data and renders the image with the corresponding viewing angle, falling within an acceptable viewing range and broadening the field of view.

"We think this display could be used in education and shopping," Toshiba explained. "For example, when shopping online, people could look at goods from various angles before buying. Technology for increasing the viewing range has a very wide variety of applications. So we'd like to keep researching not only Hands On 3D, but also various other methods for increasing the 3D viewing range."

To see the display in action, check out the video below. Unlike a good deal of videos that fail to capture 3D technology in use, the clip seen below actually shows the user tilting the prototype to see various sides of a shoe.
