  • “Super Cilia Skin is a multi-modal interactive interface, conceived as a computationally enhanced membrane coupling tactile-kinesthetic input with tactile and visual output. An array of individual actuators (cilia) use changes in orientation to display images or physical gestures as physical or tactile information”:


Using pneumatic pistons and springs:

“Behind the façade’s surface, many pneumatic pistons attach to metal plates that form the wall surface. Springs are then attached to both the pistons and the static structural frame, helping to control the location of each piston by providing it with a failsafe means of returning to a known starting point or resting state. By understanding the typical way pneumatic pistons are controlled we can also understand how the wall is actuated by distributing air pressure between two different pneumatic chambers (within the body of a piston) in different combinations to allow the piston to extend, to contract, or alternatively jitter in a mode that enables it to extend and contract very rapidly. A computer was then programmed to fire each piston sequentially in order to produce a series of patterns that responded to environmental stimuli—sound being the particular stimuli used.” Sterk, Tristan d’Estrée

These are based either on near-field ultrasound tracking, as in mimio , or on extremely skewed video acquisition. I had in mind the latter, thinking that it might be possible to use video acquisition, with the touchable surface, say, separated from a coated translucent hard sheet of acrylic or something, so that pressure upon the material causes certain regions of the sheep to appear darker (or lighter) than others. Or, in any case, arranging things such that a pattern of light and dark is what would result from pressure upon the surface.
