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.
  • FR-A-2 848 871 discloses a playing piece comprising an input, one shapeable segment and shaping means as in the preamble of claim 1.
  • the playing piece according to the invention differs from the known playing piece in that the shaping means is constructed for sequentially transforming neighboring groups of shapeable segments of the playing piece for moving the playing piece. Such a playing piece may move in a worm-like manner.
  • 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 shape of the playing piece may, for example, be influenced by touching the playing piece or talking to the playing piece.
  • the providing of playing piece information to the outside control unit makes it possible to adapt a playing piece's shape to external or player induced triggers during a game.
  • the shapeable segment comprises a skeleton of nodes and edges, each node joining at least two edges, at least part of the edges being a controlled actuator edge, and wherein the shaping means is constructed for adjusting a length of the controllable actuator edge.
  • the skeleton may be a collection of stacked polyhedrons, such as prisms or tetrahedrons.
  • the playing piece further comprises a stretchable material for covering the outer faces of the skeleton.
  • the stretchable material e.g. rubber, smoothens the surface of the playing piece.
  • the uneven skeleton comprises a lot of edges and nodes and does therefore not look or feel like a traditional playing piece.
  • 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.
  • the shapeable segment comprises at least one channel, walls of at least part of the channel comprising a pair of electrodes, the shaping means comprising a voltage source for applying a voltage difference between the electrodes of at least one pair of electrodes for contraction or stretching of the corresponding channel.
  • the walls comprise elastic material for recovering the corresponding channel to its original shape after removal of the applied voltage difference.
  • the walls comprise electrically isolating material for preventing electrical contact between the electrodes of the at least one pair.
  • equal voltages may be applied to both electrodes of the pair. In that event, an electrostatic force will result in expansion of the channel. Without the isolating material, the electrodes would make an electrical contact when the channel is contracted and applying different voltages to both electrodes would not be possible.
  • the shapeable segment comprises a plurality of the channels, walls of each channel of the plurality of channels comprising a corresponding pair of electrodes and wherein the shaping means is constructed for applying the voltage difference between the electrodes of each pair of electrodes independently.

  • the game board 16 may also be a traditional cardboard board. In that event, the control unit 17 may be comprised in a separate unit. The separate unit may, for example, be a PC.
  • An example of an interactive board game which comprises a cardboard board with a control unit 17 is the "King Arthur" game of Ravensburger (http://www.kingarthur.de/).

  • the playing piece 10 comprises a plurality of shapeable segments 11, of which not only the size, but also the shape is adjustable. If, furthermore, each shapeable segment 11 can be reshaped individually, then a large variety of shapes may be taken by the playing piece 10.
  • the playing piece 10 comprises sensing elements 15 for sensing touch, sound, acceleration, position, temperature, light or any other measurable quantity relevant to the game system.
  • Signals from the sensing elements 15 are also processed by the processor 13 and may influence the shape of the playing piece 10.
  • Signals from the sensing elements 15, may also be communicated to the control unit 17 via the output 14 of the playing piece 10 and the input 19 of the control unit 17. In this event, signals from the sensing elements 15 may influence the course of the game.
  • the shapeable segments 11 may be made of inflatable or deflatable units, the filling or emptying of which from gas or liquid in a micro fluidic or otherwise controlled manner determines the relative size and shape.

  • At least one, but preferably all edges 31 can be contracted and expanded.
  • Preferably the nodes 32 are flexible for allowing the angles between the edges 31 to vary. By changing the length of some of the edges 31, the shape of the prism is changed.
  • Figure 4 shows a controllable actuator edge 40 which may be used as an edge 31 of the prism 21 of figure 3 .
  • the controllable actuator edge 40 comprises three sections 41, 42, 43.
