Abstract

A video game apparatus and method in which two-axis output signals are produced when a surface activated with X-Y excitation signals is touched by the human finger. The control surface has a configuration corresponding to the play area on the video display. The device has the ability to sense the presence or absence of the user'"'"'s finger, as well as intensity of touch or pressure, thus adding further dimensions of control since the presence of the user'"'"'s finger on the control surface can be used to activate the video display and present the user'"'"'s playing implement, if that be the case, on the screen wherever it is touched to introduce a further element of surprise and excitement into the playing of video games.

Claims

1. In a video game system having an electronic display, electronic game generator means for generating control signals for said visual display according to the game being played, at least one player controlled signal generator, said electronic game generator means having at least one player controlled signal input means for receiving control signals from said player controlled signal generator, the improvement comprising;

at least one player touchable surface,

electric means for exciting said surface from pairs of orthogonally oriented edges thereof so as to produce a position signal field which varies linearly in a given parameter as a function of distance from one of said edges so that a player'"'"'s finger on said at least one player touchable surface generates a position signal therefrom,

means for detecting said position signal generated by the player'"'"'s finger and applying same to said at least one player controlled signal input means of said electronic game generator.

2. The invention defined in claim 1 wherein, said touchable surface includes means for changing the replica of the playing area of said game of said player touchable surface to correspond to the electronic game being played and the position of the player'"'"'s finger on said player touchable surface produces control signals for causing dynamic positioning of the player'"'"'s game element in said visual display at the corresponding position in said replica.

3. The invention defined in claim 1 wherein said player touchable surface is a resistive surface, said system including a conductive surface adjacent said resistive surface for receiving at least a portion of the signal coupled to the player'"'"'s finger and supplying same to input means.

4. The invention defined by claim 3 wherein one of said surfaces surrounds the other of said surfaces.

5. The invention defined in claim 1 including means combined with said player touchable surface for changing the visual appearance of said surface to correspond with the video game being played.

6. In an electronic game method having a video screen on which a primary playing area simulation is electronically produced with related player controlled game elements pictorially shown on said video screen, and player controlled means coupled to electrical circuits for producing coordinates of position for said player controlled game elements, the improvement comprising:

providing a secondary playing area simulation in the form of a player finger touchable impedance surface, said player finger touchable impedance surface having at least one reference edge and producing an electrical signal upon being touched which signal is proportional to the distance of the position touched from said reference edge of said secondary playing area simulation, and

controlling the position of said game element in accordance with the coordinates of position of the player'"'"'s finger on said secondary playing area simulation.

7. The electronic game method defined in claim 6 wherein said secondary playing area simulation is orthogonally excited by signals whose phase varies linearly with distance from the respective reference edges to delineate X-Y coordinates of position on said secondary playing area simulation, and

said position of said player'"'"'s game element is controlled as a function of the X-Y coordinates of position of the player'"'"'s finger where it touches the surface of said secondary playing area simulation.

8. The electronic game method defined in claim 6 including the step of sensing the pressure of the player'"'"'s finger on said secondary playing area and producing a control signal for said video game.

9. In a video game system having an electronic display, electronic game generating means for generating control signals for said visual display according to the game being played including at least one player controlled game element, at least one player controlled signal generator, said electronic game generating means having input means for receiving control signals from said player controlled signal generator and controlling the position of said game element in said visual display, the improvement in said player controlled signal generator comprising:

at least one player touchable electrically conductive surface, said at least one player touchable electrically conductive surface being a replica of the playing area of said game and adapted to be touched by one or more player'"'"'s finger,

means for electrically sensing the position of said player'"'"'s finger on said electrically conductive player touchable surface and producing a position signal corresponding thereto which position signal is applied to said at least one player control signal input means of said electronic game generator so as to control the position of the player'"'"'s game element in said visual display.

10. In an electronic game method utilizing an electronic game apparatus having a display screen on which a primary playing area is electronically produced and player operated remote control units produce electrical signals corresponding to hand motions of the player improvement in said method comprising eliminating the requirement for grasping and causing relative mechanical manipulation between structural elements and allowing more natural and convenient two axis motions without mental translation by the player,

providing at least one player touchable electrically conductive surface,

said player touchable electrically conductive surface being adapted to be touched by a player,

sensing the position touched by the player on said electrically conductive player touchable surface to produce a position signal voltage corresponding thereto which position signal voltage is utilized in said electronic game apparatus for providing the player'"'"'s input to the game in the absence of relative mechanical motion between structural elements.

11. The electronic game method defined in claim 10 wherein the position touched by said player is translated to a pair of analog voltages corresponding to the X and Y coordinates of position of the player'"'"'s finger where it touches the control surface relative to the edges of said control surface.
