Abstract

Abstract Soft control material usable as an interactive device with a user, or as a medium of communication between users on the tactile and least complex level. The material is self organizing; it uses distributed, self referent, and majority control of regions of the material, which allows greatly reduced amounts of information to be transmitted between units for communication therebetween. In its simplest form the change in total surface area of two adjacent bladders filled with Freon is detected as the individual bladder temperatures of the Freon increase or decrease to the boiling or condensing points.
