An inflatable hemispherical multi-touch display

In this paper, we introduce a multi-touch display surface that can be dynamically deformed from a flat circular display to a convex or concave hemispherical display. A rubber latex material is used for the display surface allowing it to inflate or deflate as air is pumped into or out of an airtight container. The elasticity of the display surface also allows users to deform the surface by varying the pressure exerted on it. This deformation may be detected by the device and provides a z-axis input in addition to the typical x,y-axis inputs of flat-screen displays.
