There has been an addition to the list of upcoming autostereoscopic (glasses-free 3D) devices. The latest addition is of the portable variety. Supernova X1 is a 3D-capable tablet prototype that does not rely on 3D glasses for its mojo. Engadget's Chinese site was the first to get a glimpse of this tablet prototype from China's Rockchip.
However, not a lot is known about the Supernova X1 at this point in time apart from the fact that the glasses-free 3D effect can be adjusted (or even disabled) in much the same way as the Nintendo 3DS. Rockchip will unveil this tablet at the upcoming IFA 2010 event in Germany.
