Abstract
Abstract An animated mannequin head for simulating human facial expressions. A rigid substrate in the form of a head is partially covered with elongated, pressurized fluid filled tubes. The tubes, termed tube motor elements, are either covered by or are embedded in a deformable layer/stratum, the outer surface of which is textured and tinted to simulate facial skin, the layer/stratum positioned on the head to simulate a face. Upon variation of the fluid pressure within various groups of the tube motor elements, various facial expressions may be simulated. In a first embodiment, helical coil springs are used instead of pressurized tubes, passage of direct current through the coils causing them to contract, the coils being embedded in a deformable layer/stratum. In a second embodiment, a grid of parallel wires is embedded in the simulated skin, passage of direct current through selected segments of selected pairs of wires causes them to move together, at right angles to their length, thus distorting the skin.
