Handheld controllers such as the Wii Remote make it more fun to play games. Unfortunately, that does not have a display. MagicWand is a cylindrical handheld controller with a display, allowing users to use physical gestures to interact with virtual 3D objects displayed on the wand. It has 2 flexible OLED displays wrapped around it. By rotating the wand, you can look around 3D objects.
MagicWand can be used to see a game character from all sides and interact with virtual items. Human Media Lab has more info on this technology.
