Abstract
The disclosed tactile interface device conveys a diversity of information to its operator through the operator's tactile sense without requiring the operators visual confirmation. The tactile interface device comprises a substructure on which magnets are arranged so that the positive and negative magnets are alternately placed, a frame that is movable on the substructure and on which coils are installed, and a pushbutton switch fixed to the frame. The operating element drive control means drives the switch in the two-dimensional direction by allowing current to flow through the coils in a predetermined direction, so that a motion pattern appropriate for the information to be conveyed to the operator is generated. Information is imparted to the operator from the switch through the operator's tactile sense.
