The two-wheeled toy has been embedded with electronics that can record and playback motion. As one plays with the toy, it remembers its change in position and can replay its movement forward or backward with all the intricacies of the original gesture. Every pause, and even the shaking in the user's hand, is recorded. The trails will give participants a chance to play not only with composing a movement or a dance, but also with creating graphical patterns out of simple gestures. Ensphered Vision Hiroo Iwata, University of Tsukuba Ensphered Vision, an immersive environment for one, is an image display system for wide-angle spherical screen.
Visual immersion plays an important roll in virtual environments.
However, the field of view of an HMD is limited because of its optical system. The sphere is an ideal shape for a screen that covers the human visual field. The distance between eyes and screen should be constant as the viewer's head is rotated. A single projector and a convex mirror are used to display a seamless image. The spherical convex mirror diverges the light from the projector in the spherical screen.
