Definitions

  • the invention relates to a playing piece for use in a board game, and comprising an input for receiving an input signal from an outside control unit and means for changing an appearance of the playing piece based on the input signal.
  • the invention further relates to a system for playing board games.
  • a game board comprises a horizontal display surface to support the pawn.
  • the bottom surface of the pawn comprises an image detector for detecting a control image on the display surface, underneath the bottom surface.
  • the pawn further comprises control means, coupled to the image detector for controlling an appearance or position of the pawn in dependence of the control image.
  • Light emitting diodes (LEDs) or a small LCD display screen are used for changing the pawn's appearance.
  • One or more wheels are used for moving the pawn relative to the game board.
  • the playing piece according to the invention differs from the known playing piece in that the input signal represents a particular shape and/or size of the playing piece, and in that the playing piece comprises at least one shapeable segment and shaping means for coupling the input to the at least one shapeable segment to deform the shapeable segment in dependence of the input signal for obtaining the particular shape of the playing piece.
  • the shaping means instruct the shapeable segment to deform in dependence of the input signal.
  • the shaping means may simply pass on the input signal to the shapeable segment, may redirect the input signal to different shapeable segments or may analyze the input signal and create instructions for changing the shape and/or size of the shapeable segment, based on said input signal.
  • By coordinately altering the shape of individual segments or small groups of segments a large variety of forms can be obtained. Relatively small local shape changes of the segments may result in a complete metamorphose of the playing piece.
  • the shapeable playing piece as provided by the invention can fulfill different functions during a game, or can adapt its shape depending on the game that is being played or on its function in a game.
  • This does not only allow for having a limited set of ‘electronically augmented’ playing pieces for use with a plurality of games, but also enhances the gaming experience by providing playing pieces with a look and feel that matches its function or the actual playing state. It is an advantage of the playing piece according to the invention that the players no longer have to sort the playing pieces and put them on their starting location on the game board.
  • the playing pieces can be placed on any starting location on the game board, where after each piece is shaped to the shape corresponding with the starting location.
  • the playing piece further comprises an output for sending playing piece information to the outside control unit, the playing piece information comprising at least one out of the group: identification for indicating the playing piece, location for indicating a position of the playing piece and, sensor output for indicating information sensed by the playing piece.
  • the outside control unit may reshape the playing piece in dependence of the playing piece information and/or game rules.
  • the sensor output may, for example, originate from a touch sensor, sound sensor, temperature sensor, or light sensor.

  • the stretchable material shrinks and expands together with the skeleton and gives the playing piece a more smooth and natural look and feel.
  • the skeleton encloses a cavity.
  • Polyhedrons can be assembled to form a shell. Since the polyhedrons are structurally stable, they can be assembled in a single thickness, leaving a cavity inside the object.
  • the cavity may comprise the shaping means, power elements, a light, a speaker, sensor elements or any other element needed for performing and supporting the tasks of the playing piece.
