Sphere is mainly a kind of multiple-user and the multiple-touch sensitive type of surface computing application. Infact the display is on the outer surface of the sphere rather than on the flat screen. It mainly uses the infrared cameras for the touch sensing purposes and the projectors are mainly used for the purpose of displaying the images. Both the projectors and the infrared cameras always shares the same optical axes. The display on the spherical surface can be in the form of images, videos, etc. Its plus point is that it provides the 360-degree of display. In this paper there is also the discussion about the various hardware and the software along with explanation of the working of various devices used in hardware.
