Microsoft's Sphere

After introducing the surface computer in a casino in Vegas and some selected Sheraton Hotels Microsoft introduced a new type of surface computer

At Microsoft's Faculty Summit, researchers showed off a spherical computer prototype with an internal projection and vision system. Microsoft believes surfaces will become computer displays and “Sphere” is cousin to the Microsoft Surface tabletop computer, now being used in retail and hospitality settings.

With Sphere, users can touch the surface to control the computer, to manipulate photos, play games or watch 360-degree videos. The underlying hardware for Sphere is sold commercially by Global Imagination but Microsoft researchers made enhancements and developed special software.

Curved surfaces present unique challenges as computer displays and that makes this spherical novelty of interest to digital signage installers where technological novelty can be part of the attraction.
