Abstract:
Portable, self-contained, hand-held or golf cart-mounted instrumentalities which use single-entry or recordkeeping to track a golfer&#39;s play of the game. Data can be entered by displaying a layout of a hole and pointing to locations on the layout which correspond to actual positions on the hole being played. The golfer interacts with the instrumentality via an interface composed of a view, an iconbar, and dialogs. Strokes are recorded for each hole by employing: hole selection, teebox dialog, ball position settings, club and flight dialog, and putting dialog.

       TECHNICAL FIELD OF THE INVENTION  
         [0002]    The present invention relates to novel, improved methods and apparatus for making information on one or more golfer&#39;s play available to a golfer playing a round of golf or after the round has been completed.  
         BACKGROUND OF THE INVENTION  
         [0003]    Golf is, to a significant extent, a game of numbers and other information. A golfer needs, or finds it advantageous, to know how far it is from the tee (or lie of the ball) to the pin (or at least the center of the green for each hole he plays) as well as the layout of the hole, the distance to and nature of hazards and boundaries, and other information on the hole being played. In most cases, the golfer will also want to record his score—and the scores of his golfing companions—and to compare his current with his past performances on the same and for other courses. The accumulation of data on side games such as skins, medal play, Stableford, etc., may also be desired as may a detailed breakdown of a player&#39;s round. The following is a typical list of items for which a golfer might wish to accumulate data in the course of a round for subsequent review:  
           [0004]    Greens in regulation  
           [0005]    Fairways hit  
           [0006]    Sand saves  
           [0007]    Greenside bunkers  
           [0008]    Penalty strokes  
           [0009]    Eagles  
           [0010]    Birdies  
           [0011]    Pars  
           [0012]    Bogeys  
           [0013]    Double Bogeys  
           [0014]    Triple Bogeys or more  
           [0015]    Zero putts (chip-ins)  
           [0016]    One putts  
           [0017]    Two putts  
           [0018]    Three putts or more  
           [0019]    Varied approaches to the supply of the foregoing and other information have been devised over the years.  
           [0020]    Many course operators provide maps, usually as part of a score card, which illustrate the layout of the course and which indicate the distance from the tee to the flag for each hole. Additionally, courses usually include distance markers at locations along each fairway.  
           [0021]    A variety of devices for measuring the distance between the golfer and the flag (or other feature of a hole) have also been proposed. Some of these devices utilize methods to perform distance measurement which require visual sighting of the flag, while others use the flag to support a signal receiver or transmitter. Other prior art systems rely on a coordinate system of the golf course and use linear accelerometers to track a golfer&#39;s movement along the course. Yet other systems use tracking sensors installed below the fairway turf.  
           [0022]    Still other systems, rapidly proliferating in numbers, utilize the Global Positioning System (“GPS”) for locating a player on a golf course and then calculating the distance from that location to, typically, the pin of the hole the golfer is playing.  
           [0023]    There are a number of drawbacks to the above-discussed arrangements for providing information to a player while he is on the course. The score cards on which course maps are printed only accommodate a map three by five inches in size. With all 18 holes being displayed in an area this size, details of interest to the golfer are omitted. These maps generally fail to identify hazards such as water and sand traps. Even when a course map depicts hazards, it virtually never provides distances to those hazards, nor does it typically provide other important distances, such as to the front of the green or to the back of the green. Maps are often not up-to-date. As a golf season progresses, courses can become worn from over-use. Consequently, course operators periodically relocate the tees and the flags. As a result, the distance information provided by the maps is often inaccurate.  
           [0024]    Another significant drawback of golf location systems that utilize a score card and accompanying map is that it is difficult for a golfer to track his round-by-round play at a particular course or overall. Accordingly, unless a golfer takes notes and saves old score cards, it is virtually impossible for the golfer to evaluate his performance over time.  
           [0025]    Yardage books have been said to be an improvement over posted signs and scorecard maps. However, yardage books do not provide the distance to the actual pin location. These books are cumbersome and, as the information in the book is complex in an attempt to be complete, the relevant information is often not readily available, particularly to a tyro golfer. Finally, yardage books typically do not provide distances from locations within 100 yards of a green.  
           [0026]    Relocation of tees and pins also makes distance markers inaccurate. A further disadvantage of distance markers is that they are sometimes difficult to locate. Often, hard to distinguish shrubs are used as distance markers. At other golf courses, small stakes are located along the edge of the fairway. At still other courses, small metal or cement plates are placed in the ground. These distance markers are usually of little value to those who may need them the most. Furthermore, distance markers, like yardage books, do not provide distances from locations within 100 yards of a green.  
           [0027]    More automated systems also have their drawbacks. A not always available line of sight view of the flag may be required; and this problem is compounded if golfers playing ahead forget to replace the flag after playing a hole. Those systems requiring the installation of sensors and other devices are invariably expensive to install and to service. Systems such as those employing LORAN, for example, are susceptible to electronic noise, especially that in the radio frequency range. Even electric golf carts can generate electronic noise that will adversely affect, to a significant degree, the accuracy of a LORAN system.  
           [0028]    LORAN, GPS, and other electronic ranging devices also slow play, in part due to signal loss. This is frustrating to players and can have significant economic affects on the revenue realized by a course.  
           [0029]    Another disadvantage of electronic ranging systems is that their use is prohibited by the U.S. Golf Association. This severely limits the use of such systems.  
         SUMMARY OF THE INVENTION  
         [0030]    The above-discussed and other disadvantages and failings of previously proposed devices and systems for providing information to a golfer are surmounted by the present invention. That invention constitutes a programmed device which can be used by a golfer, while on a golf course, to track the golfer&#39;s play by using a single-entry recordkeeping system. For the sake of convenience, this device is hereinafter most often referred to as a GolfWits device.  
           [0031]    The GolfWits device can be hand-held or mounted to a golf cart or golf bag.  
           [0032]    Each play of the ball is recorded by pointing on a touch screen to a graphic display of a course fairway to position the ball on the course, then entering information about how the ball was played. GolfWits displays the yardage between two points, the right club to use, the flight of the ball, the number of fairways hit, and the number of putts. Also, reference to the golfer&#39;s personal history of games played in the past, statistical data, etc., is available. The golfer may upload this data to a personal computer (“PC”) and display the information in a large-scale format or manipulate the data and print out information of interest.  
           [0033]    In the interest of providing a golfer with the simplest possible data entry format, the GolfWits device uses graphic images of the course; and the golfer simply points to ball positions on the course. Three kinds of graphics images are available:  
           [0034]    1. A generic course fairway. This image is displayed for golf courses that are currently not in a course resources database.  
           [0035]    2. A customizable golf course. This image is modifiable by the golfer—for example, choosing water, sand, fairway, and other hazards and positioning them on the screen in the configuration that best matches the hole being played.  
           [0036]    3. A reproduced course layout made for a specific golf course.  
           [0037]    GolfWits has a very simple interface for tracking the way the golfer plays the ball around the course. The interface is made up of three elements: Viewer, IconBar, and Dialogs. The golfer interacts with these three elements to record his/her play.  
           [0038]    Viewer  
           [0039]    The viewer displays generic, customizable, and specific course layouts, individual holes, scorecard information, charts, and statistical reports. It also interacts with the user by displaying popups with specific information as the user moves the pointing device around the viewer.  
           [0040]    IconBar  
           [0041]    The icons found on the IconBar launch dialogs and screen layouts.  
           [0042]    Dialogs  
           [0043]    Dialogs display both auto-acquired and requested data. Dialog boxes are used to get and confirm information from Tee, Ball, Positioning, Putting, and About boxes.  
           [0044]    GolfWits provides details akin to those available from a conventional golf scorecard including: score, handicap, yardage grid, local rules, course specifics, and graphic hole layouts. Golf Course Standard Data can be downloaded from a central computer or an Internet site containing Golf Course maps compatible with the software. The software can calculate distances and the time of play for each hole, provide course information, and club selections, and calculate statistical data based on user selection, all without employing GPS, radio, or any other communication with a second device. The GolfWits software can also display course comments by golf professionals. The software further provides a routine for storing user data, for historical statistics, and for uploading data to a central computer or server.  
           [0045]    GolfWits is, in short, a portable computer system for recording and analyzing stroke data and providing a means to calculate distances from and to any point on the hole layout. It is capable of:  
           [0046]    A. Displaying a course scorecard and hole layouts activated by the user from which a user&#39;s current score and location on a hole layout can be determined and displayed without the need for GPS, radio, or any other communication link to a second device;  
           [0047]    B. Providing course scorecard information which includes a scoring grid with yards, par, and handicaps for each hole along with space to record personal scores, accuracy, strokes in regulation and/or in fairways, putts, and strokes over par;  
           [0048]    C. Providing course layouts which include hole layouts and surrounding course features for an unlimited number of courses;  
           [0049]    D. Providing the user&#39;s current location based on user selection of hole layout, calculating distances from tees or previous points to a user&#39;s selected point and from the user&#39;s selected point to the pin or any other point of the user&#39;s choosing;  
           [0050]    E. Providing the location of the ball in the fairway, on the green, in the rough, in the water, in a bunker, in an adjoining fairway, or out-of-bounds;  
           [0051]    F. Recording club usage and the flight path of the ball;  
           [0052]    G. Automatically incrementing the number of strokes based on ball settings;  
           [0053]    H. Providing the ability to preplay, replay, or view any hole layout while on or off the course;  
           [0054]    I. Providing the ability to view the statistics of a round of golf or multiple rounds of golf in charts and tables; and  
           [0055]    J. Providing the ability to view the hole layouts with each recorded stroke on each hole.  
           [0056]    The objects, advantages, and features of the present invention will be apparent to the reader from the foregoing and the appended claims and as the ensuing detailed description proceeds in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0094]    GolfWits software is loaded onto a PDA (Personal Digital Assistant) or other small, portable, programmable, typically hand-holdable or golf cart-mountable computer to provide what is herein referred to as a GolfWits device. GolfWits software can be written to run on a Windows CE/NT/9X, Palm, or other operating system.  
         [0095]    [0095]FIG. 1 depicts one of many devices with a touch screen  79  which may embody the principles of the invention. This device is identified by reference character  80 . FIG. 1 is not intended to depict a dedicated piece of hardware.  
         [0096]    How the GolfWits device  80  is employed for its intended purpose is described below.  
         [0097]    The user connects GolfWits device  80  to a PC (personal computer)(not shown) by way of the computer&#39;s serial port. He then connects to an Internet site and downloads the maps for the courses the user is going to play. The user then copies the course map the user wishes to play from the PC to GolfWits device  80 .  
         [0098]    At the golf course and with the device in the user&#39;s hand (FIG. 1), the user selects OPEN choice  82  from the File Menu  84  shown in FIG. 2, bringing up the OPEN COURSES menu  86  of FIG. 3. From the OPEN COURSES menu, the user selects the course  88  he is going to play and presses OK button  90 , causing the steps shown in FIG. 4 to be taken to bring up the expanded menu  92  of FIG. 5. Alternatively, if the golfer changes his mind, he can press button  94  to cancel his choice.  
         [0099]    In a representative scenario, the user selects SCORECARD option  110  from the FIG. 5 menu  92 . This puts GolfWits device  80  in the scorecard view mode  112  (FIG. 6). The scorecard headings are as follows:  113  is the hole number;  115  (Tee) shows the yards from a tee to the center of the green for a hole (by default the yards from the furthest tees are displayed):  116  is the handicap for the hole;  118  is par for the hole;  120  is the golfer&#39;s score;  122  is a drive found in a fairway;  124  is a green hit in regulation;  126  is the number of putts; and  128  is the number of strokes over par. Reference characters  130  and  132  identify scroll buttons that can be selected to scroll the rows of the FIG. 6 scorecard up and down respectively. Reference character  134  indicates the row containing data for hole number 1. Row  136  (out) contains the totals for holes 1 through 9. Reference character  138  identifies a ply tab which is blank until the golfer enters his/her name or multiple golfer names in which case more ply tabs are added.  
         [0100]    From menu  92 , the user chooses Profile (see reference character  140 , FIG. 5).  
         [0101]    A Golfer Profile dialog  142  then appears (FIG. 7). The user enters or selects a golfer name in the Name box  143 . He then fills in the Swing entry  144  and enters the player&#39;s sex in box  146 . The user then enters the player&#39;s handicap  148  and, in box  150 , the number of the club with which the player hits a ball  150  yards. He then enters the tees he wishes to play from by using the plus and minus buttons  152  and  154  to make selections from list  156 . The user can also select the plus sign  153  to bring up a blank profile in order to make entries for a second golfer (up to 4 golfers can be accommodated).  
         [0102]    [0102]FIGS. 8 and 9 show GOLFER PROFILE dialog boxes  158  and  160  with exemplary entries.  
         [0103]    The result of completing the FIG. 8 and FIG. 9 dialog boxes  158  and  160  (and two others which are not shown) is a scorecard  162  with golfer ply tabs  164 ,  166 ,  168  and  170  populated for four golfers Kent, Hal, Roger and Suzanne (FIG. 10) and a group ply tab  172 .  
         [0104]    [0104]FIG. 11 shows a flow diagram of the GolfWits device  80  operations from the point in time in which the GolfWits device is waiting for the golfer to make a selection box ( 216 ).  
         [0105]    Continuing with FIG. 11, if the golfer selects a point on GolfWits device screen  79  with scorecard  162  displayed other than a menu item, the GolfWits software determines what selection has been made. For example, if the selection  218  is a Row header, the GolfWits software determines which row  220  was selected and checks (at  228 ) to see if that row represents a hole number. If the row does represent a hole number, GolfWits device  80 , as shown by reference character  242 , displays the hole layout for that number.  
         [0106]    For example, if the user selects Row  1  (any row can be selected in any order), the layout  224  for hole one appears (FIG. 12). The golfer&#39;s name appears in the top left corner of the layout at  226 . This helps to identify which golfer&#39;s display is being used. Each of the four golfers may keep his/her score using a hole layout which will record their score and the way they played the hole.  
         [0107]    In FIG. 12, reference character  228  identifies the green. Reference character  230  indicates the hole number, and reference character  232  is the location of the tee for the golfer. This can be adjusted by selecting the ball and moving it to the appropriate position.  
         [0108]    Reference character  234  identifies an exemplary sand trap, and  236  is an example of a green side bunker. Reference character  238  identifies additional details surrounding the current hole, like other nearby fairways. Reference character  240  identifies the status bar for the hole layout. The status bar shows a variety of data; viz., the par  242  and the total distance  244  from tee to flag. The handicap for the hole is  246 , and  248  shows the current score for the golfer on the hole.  
         [0109]    At this point the golfer selects TEE option  250  from Menu  92  (FIG. 5); and Tee Adjustment dialog box  252  appears (FIG. 13). In this figure, reference character  252  shows the default distance from the tee selected. The plus and minus buttons  254  and  256  allow the golfer to increment or decrement the yards from the default tee to provide the number of yards from the actual tee location to the flag in box  258 . The golfer then selects OK button  260  to continue. The tee-to-green for this hole is stored in memory  262  (FIG. 15).  
         [0110]    The golfer  264  tees up his/her ball and makes a shot (FIG. 14). The golfer now walks out to the ball and selects a point on the screen  79  that best represents the position  266  of the ball on the hole layout  224  (FIG. 16). If the selected point is new and the point was not locked by a second click, the GolfWits software calculates the distance  267  from the previous position  268  to ball position  266  and the distance  269  from the ball position  266  to pin  270 . Then, the ball location is displayed as a dotted rectangle  272  containing the distance from the ball to the pin  270 . Status bar  240  now displays at  274  the club used to hit the ball that distance  267  and, at  276 , the suggested club for the second shot.  
         [0111]    Golfer  264  next selects BALL option  278  from Menu  92  (FIG. 5), and Ball Position dialog  280  appears (FIG. 17). The ball position  282  is determined automatically by the GolfWits software. The user can change this selected location if he/she wishes by pointing to another option in box  284 ; and the golfer can point to screen  79  to enter the club used for the first shot at  286  and/or identify the flight of the ball by pointing to one of the flight paths such as  288 .  
         [0112]    [0112]FIG. 18 shows the selections made by the golfer. Now the golfer selects OK button  289  to continue.  
         [0113]    Pushing the OK button brings up on screen  79  an updated layout  290  (FIG. 19). The ball position rectangle  16  has been updated to a ball  292 , and the flight path  294  of the ball has been drawn. The golfer&#39;s score is updated on status bar  240 .  
         [0114]    The golfer now selects the ball position again to determine how much further he has to go to the flag. Club selection and distance rectangle  296  appear (FIG. 20) on the hole one layout  298 . The status bar  240  displays information on the previous shot at  300  and the new distance  302  from the current ball position to the hole one flag.  
         [0115]    If the golfer selects the same point  282  a second time, the position is locked—see  304 ,  306 ,  308 , and  310  (FIG. 15). This causes a solid line box  312  to appear in the updated hole one layout of FIG. 21. The golfer can select any other point, for example point  314 , to appear on screen  79 . The GolfWits software calculates the distance between the locked-in point  282  and the new point  314 . The status bar  240  now displays the first shot club and distance data  300 , the suggested club for the new distance (reference character  316 ); and the suggested club for the distance from the last point to the hole one pin  320 .  
         [0116]    The golfer  264  makes his/her second shot (FIG. 22) based on the information given by the GolfWits device  80  (FIG. 1). The golfer walks up to the ball after the shot and makes a reasonable estimation as to where on the updated layout  325  of hole one his/her ball is (FIG. 23). The remaining distance to the pin is displayed in a dotted rectangle  322 . The distance from the previous position  266  and the club used for that shot are displayed in the status bar  240  at reference numeral  324 . The club selection for the next shot and the distance to the pin are displayed in the status bar at  326 .  
         [0117]    The golfer selects the BALL POSITION option  278  from the Menu  92  (FIG. 5). The golfer enters club and flight data for the second shot in the “Ball Position” dialog box  280  (FIG. 24).  
         [0118]    [0118]FIG. 25 shows the layout  328  for hole one as then updated by the GolfWits software.  
         [0119]    With his/her second shot, the golfer has reached the green  228  of hole one. The golfer therefore selects PUTTS option  330  from Menu  92  (FIG. 5). The “Putts” dialog box  332  is brought up (FIG. 26), and the golfer enters the number of putts taken on the green in box  334 . The strokes from tee to green are calculated by the GolfWits software and displayed in box  336 .  
         [0120]    When hole one has been completed, the user can view his/her score by selecting the SCORECARD option  110  from Menu  92 . What the golfer sees is an updated scorecard  340  (FIG. 27). With the updating having been done automatically by the GolfWits software, the golfer  264  can now also enter the scores of the other players (see FIG. 28). It is possible to record the same information for all the golfers at any time during play; it is not recommended that one golfer keep score this way, but it is possible if time permits.  
         [0121]    The golfer selects the ply tab  166  of the next golfer (Hal). The scorecards as updated and identified by reference character  340  in FIG. 29 will now display the data for golfer Hal.  
         [0122]    The golfer selects the cell  342  in column (Scr.  1 , FIG. 30) which accepts golfer Hal&#39;s score for hole one. Upon selecting this same cell a second time a numeric input pad  344  appears, and an edit window (not shown) is opened for cell  342 . The golfer can select any number on the pad, and it will appear in the selected cell  342 . The golfer can now select the cell  348  (Putt  1 ) that represents the number of putts taken by Hal on the first hole (see FIG. 31) and perform the same steps that were utilized in entering the total hole score to record the number of Hal&#39;s putts on hole one.  
         [0123]    These steps can be repeated for each golfer. Then, the golfer can select the ply tab “group”  172  to view a leader board  350  (FIG. 32) for the group. After five holes have been completed the leader board  350  might appear as shown in FIG. 33.  
         [0124]    The golfer can view the statistics of his play by selecting the STATISTICS option  352  from Menu  92  (FIG. 5). The representative “Statistics” display  354  of FIG. 34 will appear.  
         [0125]    If the golfer has elected to play a golf game by selecting the GAMES option  356  from Menu  92  (FIG. 5), the golfer can also view the status of the games that are being played on the Group Scoreboard as shown in FIG. 35 and identified by reference character  358 . Thus, reference character  360  depicts a skins carryover; and reference character  362  depicts a skin that is won by the circle. Reference character  364  depicts a game of Bingo-Bango-Bongo, where one golfer has won the Bingo and Bongo. Reference character  366  represents Bingo, reference character  368  represents Bango, and the reference character  370  represents Bongo. The definitions of these terms are as follows: Bingo—First on the green; Bango—Closest to the hole after the second shot; Bongo—First in the cup.  
         [0126]    The golfer can then view the statistics for his/her 18 hole game by scrolling to the bottom row  372  of the scorecard (FIG. 36).  
         [0127]    The golfer can view his/her handicap by counting the dots  374  on the scorecard (FIG. 37). If a golfer&#39;s handicap were 13, there would be 13 dots in the cells under the column heading Scr (Score). Each dot  374  represents a stroke given to the golfer and subtracted from his/her net total score to get a net score. (FIG. 36).  
         [0128]    The golfer can also set targets on a hole layout (FIG. 38). Those targets are used to show how accurate his/her strokes are. The targets for representative hole one are identified by reference characters  378  and  380 . Then the golfer plays each hole and selects the position that best represents the location where the golfer&#39;s ball landed. The GolfWits software then calculates whether or not the golfer hit his/her target based on the acceptable distance that was set by the GolfWits user. If the target is missed, one of four characterizations of the shot may appear: (1) short; (2) long; (3) right; or (4) left.  
         [0129]    As set forth in the summary of the invention, the GolfWits device is capable of displaying customizable course layouts, individual holes, scorecard information, charts, and statistical reports. Specifically, the GolfWits software allows a golfer to customize the statistical data input into and retrieved from the GolfWits device. Specifically, a formula parser inside the GolfWits device allows the golfer to write customizable formulas relating to the statistics of a golfer&#39;s play. It should be noted that the formula parser may be a stand-alone parser or may be incorporated into the GolfWits device or software.  
         [0130]    In use, the golfer may write a formula in a text file format. The formula may be written using the GolfWits device, other handheld device, or an external computer. The format that may be followed is a dual column format, in which each column is separated by commas and each column is enclosed in quotes. It is preferred that there be only two columns per row so that a formula may be written and easily viewed on the GolfWits device or other handheld device.  
         [0131]    To activate a customized formula previously entered by a golfer, the golfer may select the CUSTOM option from the Menu and select a particular customized formula he wishes computed. When the formula is selected, a formula parser activates and searches the GolfWits software for the existence of a “personal” formula file with the formula therein. If the “personal” file is found, the formula parser opens the file, reads a desired formula into memory, runs the appropriate programs so that a desired formula is calculated, and stores the calculated values until the results appear on the STATISTICS screen of the Golfwits device.  
         [0132]    For example, if a golfer desires to know the percentage of golf shots that the golfer sliced, the golfer may enter a statistical formula that calculates the percentage of golf shots the golfer sliced. The resulting formula might be “%Slice,”=PERCENT(TOTAL(BALLPATH(HOLES(1-18), NUM(0), 0)), SUB(TOTAL(SCORE(HOLES(1018))), TOTAL(PUTTS(HOLES(1-18),10))), 2)”. In another example, a golfer desiring to know the number of par 3 holes in an 18 hole golf course may enter a statistical formula that displays the number of par 3 holes on an 18 hole golf course. The resulting formula might be “Par 3s found in holes 1-18”, “=PAR(HOLES(1-18), 3)”,.  
         [0133]    After the round of golf is completed and the scores have been entered, the golfer may review the round by selecting the PLAYBACK option  382  from the Menu  92  (FIG. 5). Every stroke placed on each hole layout will be cleared and replayed. A simulated ball will follow the recorded flight path. The user can thereby get a unique feel for how well he/she played.  
         [0134]    While the invention is described and illustrated here with respect to a particular embodiment, the invention may be embodied in many forms without departing from the spirit or essential characteristics of the invention. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
