Digital Clay is a new generation of 3D computer input and output device for surface shape. Its three control levels are introduced in this paper. The device consists of arrays of fluidically actuated cells under the control of valves, that are connected to two pressure reservoirs in a manner ultimately suitable to an implementation in MEMS technology. Preliminary research on control related behaviour is described including testing of a single cell under a proposed control scheme. Based on these tests, control methods are presented and discussed that achieve elastic, plastic and elastic-plastic material behaviours.
