Abstract
In accordance with one preferred embodiment, a miniatures playing surface is provided which includes an isometric grid ruling for positioning miniatures.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/509,218, filed on Sep. 18, 2003, the entire disclosure of which is hereby incorporated by reference herein.
- 1) Field of Invention
- This invention relates to miniatures games
- 2) Discussion of Related Art
- Two types of miniatures playing surfaces have been employed in the past. Each of these technologies has certain disadvantages.
- A common miniatures playing surface is a large piece of graph paper. It is ruled with a standard grid of vertical and horizontal lines. Disadvantageously, the three-dimensions of the real world are not well-represented using a two-dimensional map.
- It is an objective of the present invention to overcome some or all of the above limitations. In accordance with one preferred embodiment, a miniatures playing surface is provided which includes an isometric grid ruling for positioning miniatures.
- Having thus summarized the general nature of the invention and its essential features and advantages, certain preferred embodiments and modifications thereof will become apparent to those skilled in the art from the detailed description herein having reference to the figures that follow, of which:
-
FIG. 1 is a plan view of the preferred embodiment of the invention withminiature 1 andcolored piece 5 shown in isometric view for purposes of illustrating the function of the invention. -
FIG. 2 is a plan view of the preferred embodiment of the invention. -
FIG. 3 is an isometric view ofcolored ring 4 -
FIG. 4 is an isometric view ofcolored ring 4 attached tominiature 1. -
FIG. 5 is an isometric diagram view of another embodiment of the invention -
FIG. 6 is a flow chart of the control circuit controlling the motor in the embodiment shown inFIG. 5 -
FIG. 7 is a series of graphs showing how power to the motor of the embodiment inFIG. 5 is supplied to cancel out friction and detent effects. -
FIG. 1 of the accompanying drawings illustrates an isometric miniatures playing surface.Miniature 1 is comprised offigurine 2 attached tobase 3. Coloredring 4 attaches tobase 3.Colored piece 5 matches coloredring 4 in color, indicated by their matching cross-hatch shading inFIG. 1 . Bothminiature 1 andcolored piece 5 rest physically on playingsurface 12, which is a poster-like sheet with a printed surface. Terrainrepresentation 9 is printed on playingsurface 12, giving the players the sense of three-dimensional terrain even though the playing surface is two-dimensional. Playingsurface 12 is ruled with apattern 6 which is comprised of x-lines 7 a and y-lines 8 a. x-lines 7 a and y-lines 8 a each make angle 11 with the horizontal of 30 degrees. -
Colored piece 5 serves an important purpose. It marks the location of the vertical projection of the miniature to the ‘ground’. For example,miniature 1, sitting onisometric square 14, could either be on a square behind theterrain representation 9, or on top ofterrain representation 9. It is unclear which case is correct because three-dimensions are being represented on a two-dimensional surface, creating a loss of information. However, if it is assumed that any isometric square is on the ‘ground’ if it has no terrain representation around it, then we can usecolored piece 5 to give us a reference to the ground surface. Ifcolored piece 5 is always considered on the ground surface and also directly underneathminiature 1, then whenminiature 1 andcolored piece 5 don't rest on the same isometric square, it can be reasoned thatminiature 1 is on a higher plane than the ground surface, and that the number of squares fromcolored piece 5 tominiature 1 indicate the height ofminiature 1 from the ground. InFIG. 1 ,miniature 1 is on the 3rd square fromcolored piece 5, indicating thatminiature 1 is 3 units of height above the ground. Thecolored piece 5 introduces additional information about the location ofminiature 1 in space—it is now clear thatminiature 1 is on top ofterrain representation 9, not behind it on the ground. Ifcolored piece 5 andminiature 1 both rested onisometric square 14, it would indicate thatminiature 1 was behindterrain representation - The
base assembly 13 ofminiature 1 as it appears in a true plan view is illustrated inFIG. 2 .Base assembly 13 is approximately 25 mm in diameter. Edges 8 c and 7 b ofisometric square 14 are each approximately 30 mm in length. Numbering 15 a and lettering 15 b along the edge ofplaying surface 12 allow the identification of specific isometric squares. For example,miniature 1 is on h8. -
FIG. 3 shows an isometric view ofcolored ring 4. Coloredring 4 in the preferred embodiment hasgrabber fingers 102 andbottom surface 104 to aid in attachingcolored ring 4 tominiature 1. Slit 106 allowscolored ring 4 to expand to encompass thebase 3 ofminiature 1.Colored ring 4 is preferrably made out of a flexible plastic like polypropylene. In the preferred embodiment,colored sticker 108 is applied to the outside ofcolored ring 4. - In
FIG. 4 ,colored ring 4 is shown attached tominiature 1. It can be seen thatgrabber finger 102 andbottom surface 104 support the top and bottom surfaces ofbase 3 ofminiature 1. - In the preferred embodiment,
terrain representation 9 ofFIG. 1 is printed with an ink that is invisible initially. When a revealing marker is scribbled across the surface of playingsurface 12, the invisible ink becomes visible. This allows players to game master themselves. A player can begin at one end of the map withminiature 1, scribble a revealing marker across playingsurface 12 where theminiature 1 approximately begins, and then advance the character across the map, according to the rules of the game, scribbling a revealing marker to show more and more of the map. Advantageously, the map is kept secret from the player, so that there are opportunities to surprise the player as he or she works through the map. It involves a method of: -
- 1) setting out playing
surface 12 with a terrain representation printed in invisible ink on a surface - 2) setting
miniature 1 at a prescribed location on the map based on the story and rules of the game - 3) scribbling with a revealing marker according to the story and rules of the game, generally near miniature I's location.
- 4) playing the game and reading the story further
- 5) deciding on a course of action, then consulting the game material to determine a specific area on the
playing surface 12 to reveal - 6) scribbling with a revealing marker in accordance with the directions
- 7) repeating the process of reading game material, following directions, and scribbling to reveal more map as directed.
- 1) setting out playing
- Changes could be made to the above embodiment. For example, x-lines 7 a and y-lines 8 a could use a different value for angle 11 instead of 30 degrees. The angle x-line 7 a makes to the horizontal could differ from the angle y-line 8 a makes to the horizontal. The grid could be in perspective, so that each line of the series 8 a or 7 a have slightly different angles to the horizontal.
Miniature 1 could be a single-piece miniature consisting only offigurine 2 andbase 3. Playingsurface 14 could be made out of vinyl instead of paper, andterrain representation 9 could be drawn on the vinyl with an erasable ink. - Another embodiment of the invention is shown in
FIG. 5 .Motor 1002 drives universal joint 1004 (shown in schematic form for easier understanding) which in turn drives cable-wrappeddrum 1006. Cable-wrappeddrum 1006 is wrapped withcable 1008, with multiple turns. Each end ofcable 1008 attaches tolarge drum 1010 which is rigidly attached toarm 1012.Large drum 1010 rotates aboutaxis 1024 which passes throughbearing 1022.Bearing 1022 is attached to right-angle frame 1018. Right-angle frame 1018 hasbearings 1020 a and 1020 b, which axis 1030 passes through. Axis 1030 passes directly through the axes ofrotation angle frame 1018 can rotate about axis 1030 to the extent allowed by universal joint 1004 without binding (typically about 45 degrees in either direction for about 90 degrees total travel). -
Motor 1002 is driven bycontrol circuit 1014, which is controls power frompower source 1016.Motor 1002 in the preferred embodiment is a common appliance-style motor which includes electromagnets for generating the magnetic field that the coils use to push against, instead of a permanent magnet style motor. The electromagnets can be switched on and off by the control circuit.FIG. 6 shows part of the logic of the control circuit. If zero-force is required, meaning that movement ofarm 1012 should not be impeded by magnetic detents inmotor 1002 caused by the aligning of steel inmotor 1002 with permanent magnets, or in this case the energized electromagnets, the electromagnets are switched off, thereby eliminating the field that the steel inmotor 1002 is seeking to align with. -
FIG. 7 shows a more complex method of preventing magnetic detents as well as friction effects frommotor 1002. (in the embodiment ofFIG. 5 , the method used in the previous paragraph is preferred). Graph (a) shows the torque (T) as a function of the angle of the motor shaft ofmotor 1002. Graph (b) is the countering torque applied bycontrol circuit 1014 based on the known angle of motorshaft angle sensor 1032 ofFIG. 5 . When the effects represented by graph (a) and graph (b) are added together, the result is graph (c)—the original effects of graph (a) have been cancelled out by the superpositioning of the effects of graph (b). -
FIG. 8 shows another embodiment of the invention.Flexible tube 2000 has a plurality of cables (1 is shown for clarity) running through it.Cable 2002 slides inside offlexible tube 2000.Cable 2002 attaches to force-sensing element 2004, which is comprised in the preferred embodiment ofelastic member 2006 and position sensor 2008 (shown schematically for clarity).Cable 2002 actuates grabber finger 2010 through force-sensing element 2004.Position sensor 2008 sends a signal along signal carrier 2012 to control circuit 2014, which controlsmotor 2016.Motor 2016 drivescable 2002 throughcable transmission 2018, which pushes and pulls oncable 2002.Rack 2020 moves back and forth along direction 2026 by the rotation of drum 2022 bymotor 2016, which in turn pulls on either end of pretensioned cable 2024 (which is wrapped around drum 2022). Force control of grabber finger 2010 is established by control circuit 2014 as follows: desiredforce input 2028 is read in from a source (typically a master force-feedback device controlled by a user), which is compared against the reading of force-sensing element 2004 through signal carrier 2012.Motor 2016 is powered to exert oncable 2002 by control circuit 2014 to match the actual force to the desired force. Control circuit 2014 also feeds backfeedback signal 2030 to the source to allow the source to know what the force atforce sensing element 2004 currently is. This embodiment has the advantage that since the force sensing is done after all of the friction, stiction, and other negatives offlexible tube 2000, force control is much more accurate and controllable.
