Inventor(s)Kelson; Steven M. (5412 Ranger Dr., Rockwall, TX 75087); Kelson; Robert E. (2409 Knights Bridge Dr., Grand Prairie, TX 75050)
AbstractThe system uses a microcomputer (81) to provide a practical and useable graphic representation of the fairways (12) and greens (11) for any golf course in order to record shot locations (14) and measure playing performance during an actual round of golf as contrasted to a simulation of a golf game. A player will interact with the diagrams produced by the system's software and illustrated on a display or monitor (80). The design of the system enables the player to accurately determine the locations of all shots and calculates and displays: (a) shot or club distances (FIG. 6 ); (b) shot or club accuracy (within 1-2 yards) to the center of the green from ball locations (14) ranging up to 200 yards from the center of the green; (c) shot or club accuracy (within 1-2 feet) to the pin (cup location) from ball locations (14) ranging up to 200 yards from the center of the green even though the pin location may be different each time the course is played; (d) statistical data, i.e., score, fairways hit (68), greens in regulation (69), a correctable swing analysis (71), and a complete short-game analysis (54) of putting (63, 64, 65, 66), sand saves (60, 61, 62), and chipping (55, 56, 57, 58, 59); and (e) playback of golf rounds (FIGS. 3 A, 35, 3C) so that improvement can be measured and selected courses played in the past can be reviewed and analyzed.

An appendix of 31 microfiche and 1000 pages is attached to this specification and is contained in the file wrapper of this patent.

BACKGROUND

1. Field of the Invention

The invention relates computer systems and methods for use in the game of golf, particularly to a computer method for creating a universal golf course to enable accurate and graphic display of shot accuracy and distance for each club used in an actual round of golf to help players improve performance.

BACKGROUND

2. Description of Prior Art

Golfers strive continually to improve their play, i.e., lower their scores. One major way they do this is to record data about actual play of a round of golf on a course and thereafter analyze the results at home.

In order to utilize the results of a round of golf to help improve performance, a golfer had been forced to keep handwritten documentation of all shots played. Then the golfer had been faced with the difficult and time-consuming task of manually organizing the data and breaking down the results achieved with each club.

College golf coaches also use various methods of recording statistical data for their student players in an attempt to improve individual and team performance. As this normally requires considerable time and effort on the part of the students to complete data sheets, many of them dislike the task. Generally, the student's data sheets are sent to a data processor and several days elapse before the results are known. The results come back in the form of printouts which generally include information such as average score per round, average number of putts per round, number of birdies (holes played in one stroke under par), etc. However, the results are delayed and normally not available for use during a current tournament. Also, nothing is provided regarding accuracy and distance accomplishments with each club used in play. It is generally acknowledged that knowing proper club selection, and knowing one's average distance with each club, can help to improve one's performance at all levels of playing proficiency.

Computer games have been offered which provide entertainment for computer players to test their computer skills against the hypothetical playing of famous golf courses around the world. In some of these games, each hole has been meticulously duplicated so the computer player can get a feel of the golf course.

U.S. Pat. No. 4,504,055 to Wells (1985) shows an electronic video game adapted for use to play a simulated game of golf. Wells's game is a competitive one where the players compete on a fixed course and play by selecting clubs, directions, and strengths of shots. This machine plots successive lays of the ball. However, this type of computer activity merely provides entertainment and does not aid in the improvement of one's golf playing ability.

U.S. Pat. No. 5,184,295 to Mann (1993) shows a computer program and system for teaching a student how to play a game, specifically golf, in a superior manner. It compares a video of the student performing with a model compiled from a plurality of elite performers in order to teach the student what to do to improve play and emulate the superior model. Consequently, this system is dependent upon the physical ability, coordination, and aptitude of the student to correctly emulate the model in order for the student to improve.

U.S. Pat. No. 4,343,469 to Kunita et al. (1982) shows a computerized putting simulator where the computer considers the velocity and hit angle of the ball on the topography of the green and plots a trajectory of the putted ball. This putting practicing machine is designed merely to help a golfer improve putting performance, not general golf play.

U.S. Pat. No. 4,815,020 to Cormier (1989) shows a hand-held computer attached to a hand-held cart holding a golfer's bag and clubs. The computer computes the club to be used on the next stroke based upon previous strokes and the distances achieved with such clubs. Also, the remaining distance to the green is computed based upon the distance traveled thus far, which is measured by a sensor attached to a wheel of the golf cart. In most competitive college golf tournaments the players are required to carry their bags and clubs, and if not required, it's a common practice in high school golf competitions. This fact, plus the increasing use and requirement of motorized riding carts on most golf courses, limits the practical application of the Cormier device. In addition, Rule 14-3 of The Rules of Golf (The U.S. Golf Association, Jan. 1, 1992) states: "Except as provided in the Rules, during a stipulated round the player shall not use any artificial device or unusual equipment: . . . b. For the purpose of gauging or measuring distance or conditions which might affect his play . . . ". Thus, Cormier's device may be illegal in USGA tournaments.

U.S. Pat. No. 5,056,791 to Poillon et al. (1991) shows a system for use indoors to simulate outdoor play. The player hits the ball into a frame which has a hole of the real golf course projected on a screen in the rear of the frame. The computer senses the characteristics of the hit ball, including trajectory, velocity, and spin, and computes the actual travel it could take on the real course in an unimpeded environment which may or may not simulate varying conditions such as wind, rain, and temperature under actual playing conditions. Pictures of holes of a plurality of real courses are stored in the computer on a CD-ROM.

U.S. Pat. No. 5,221,082 to Curchod (1993) shows a system very similar to Poillon's, but where the player's shots are enhanced by a predetermined factor in order that the player will be competitive with other players.

U.S. Pat. No. 4,086,630 to Speiser et al. (1978) shows a computer-type golf game which works in conjunction with a slide projector to present successive scenes of the course and hole in play, hole distances, and lays of the ball, and completion (yards to go) to the pin. Speiser describes an unrealistic simulation whereby an out-of-bounds drive occurs when a ball hits a side wall of the drive range with an insufficient impetus on the rebound to activate the net switches. This example clearly illustrates a difference between simulated golf play and real golf play. In actual play such a shot may or may not result in an out-of-bounds situation. Most golfers readily agree that hitting golf balls during actual play on a course, especially in competition, is different from hitting balls on a driving range, or taking practice swings at an imaginary or real target such as a dandelion, or taking golf swings in a simulated environment.

Further, distances representing hits measured by these simulators are not hits of golf balls during actual golf play subject to usual variances in temperature, wind, and other atmospheric conditions. Instead, they are simulations which are physically measured by various types of sensing devices including sound wave detectors, and sensors measuring velocity, trajectory, and spin of the ball.

Also, these systems require simulation of play on specific golf courses. Because each golf course throughout the world is different from other courses in layout, design, and distances for each hole, it is exceedingly difficult to duplicate each layout as an instructional aid in the teaching of golf. To meet the needs of all golfers across the country, a great deal of time and expense would be required to enable the system to simulate the varied and numerous courses. The cost of these devices practically prohibit the average, individual golfer from owning and using or practicing with such devices. In addition to the relative high cost of such devices for individual golfers, most golfers prefer actual play rather than simulations of play.

U.S. Pat. No. 3,665,494 to Baumoel (1972) shows a handicap computer which takes into account the previous scores of the player and the courses where these scores were posted. This computer uses a punch card for input, which by today's standards, is impractical or obsolete. Handicaps are used to equalize competition, generally among members of golf clubs. For example, a scratch (zero) handicap player will give a seven handicap player seven strokes to equalize play in a round of golf. Other than indicating relative playing proficiency compared to other golfers, this device does nothing to improve a golfer's playing ability.

Sports Performance Research of Loveland, Colo. provides a computer statistical quality control system (1992) for golfers which presents a method of recording the distance of a golf shot, prior to making the shot, based on a player's estimate of the distance from the ball location to a target. In many cases, especially on a golf course with which a player is unfamiliar, such an estimate could be inadequate. This statement is verified by the user's manual which states: "If you can't make a good estimate of the distance, it is better to leave this column blank than to enter a poor guess."

Another instruction states: "Make an entry in the Yards to Target column whenever you can make a reasonable estimate of the distance from your ball to the pin." In view of the fact that pin locations are regularly moved daily, unless a player is informed of the exact location of each pin on each green, accurate estimates are further impaired.

In addition, the calculation of distances is further complicated by the requirement: "If you are making a shot from behind the green, enter a minus sign in front of the distance you enter. This notation tells GolfSQC [the associated program] your previous shot was hit too far."

This system uses a data gathering procedure requiring the use of specific, detailed Stroke Logging Charts and uses charts and graphs to display results of individual golf play. The system creates a profile of a golfer's game so the golfer can compare performance with a profile of professional golfers and others; however, the user's manual warns: "if less than 50% of your holes don't fit the templates or the round estimates are a lot different than your typical scores, GolfSQC probably isn't for you."

Studying charts and graphs offer little appeal or interest for most athletes or golfers, especially young people. This is an important consideration in the design of a golf improvement system. Many leading golf teachers feel, that in order to reach top levels of performance in golf, students must develop interest and be encouraged at a relatively early age.

AV Systems, Inc. of Santa Barbara, Calif. provides a computer game (1992) which can simulate several courses with several players.

Focus/2000 and Golfmaster/2000 of Shawnee, Kan. (1990,1992) provide a computer program for calculating and retaining scores for a day or a season. It can record hole and stroke play, golfer statistics, etc.

However, both of the latter two games suffer from most of the disadvantages of the devices of the above-described patents.

OBJECTS AND ADVANTAGES

Accordingly several objects and advantages of the present system are:

(a) to provide an appealing, relatively low cost, time efficient, and easy-to-use system, which provides the capability for analysis of a current day's play with a complete performance analysis of individual and team players for a round of golf played on any eighteen-hole course in the world;

(b) to provide a universal golf hole which facilitates the foregoing object and which can be used to simulate any golf hole in the world;

(c) to provide a playback capability, i.e., a record which can be reviewed upon demand and provide a graphical picture of each shot location in a round to aid a player's memory recall and visualization of each shot;

(d) to provide, as a result of the foregoing object, the means to enable any golfer, including professional golfers, to recall how they played the same course a previous year;

(e) to provide reports and graphical pictures of shot accuracy, e.g., approach shots to the green from distances ranging from 1 to 200 yards;

(f) to provide accurate information to help a golfer learn the average and maximum distances the golfer can hit each club under playing conditions, and

(g) to provide a system that will operate on standard microcomputers widely available and easily accessible at relatively low cost to help golfers of all handicaps improve performance.

Several additional objects and advantages are:

(h) to provide reports on demand to enable golfers to evaluate progress or improvement; and

SUMMARY

In accordance with the present invention, we provide a golf play analysis system which is operated on a hand-held, laptop, or a standard desktop microcomputer with a screen and data entry keys. The screen of the computer provides a diagram of a universal golf course which can portray any golf hole, regardless of shape or size. The computer's keys are used to enter data about the game, including the measurements of the course, clubs used, and shots made on each hole, etc. The system records and displays the recorded data so that a player can analyze and improve current play and also past games to improved future play.

DESCRIPTION--FIG. 1--SCORECARD

The present system is used to record data about and analyze a golfer's game and then improve the golfer's game. During actual play, specific information is recorded during or after the play of each hole and therafter the data is entered into the system and it provides selective outputs which help the golfer analyze and improve performance.

FIG. 1 illustrates a sample paper or cardboard scorecard, similar to a standard scorecard (not shown), which shows specific items recorded. Proficient golfers develop an ability to remember most of the shots and details from a round of golf and may not necessarily require written notation of all items shown in FIG. 1. However, the scorecard of FIG. 1 is organized in the order of data entry required by the system. Therefore, use of written data on a scorecard similar to that illustrated in FIG. 1 will facilitate and, in most cases, lessen the time required for data entry into the computer system. The scorecard has been partially completed with data of a player's performance on hole #1 of a course and will now be reviewed.

Row 01 (Strokes to Gr) illustrates that three strokes were taken on hole #1 to reach the green.

Row 02 (Probs? Y/N) illustrates that yes (Y), the player had a problem with or considered shot #1 to be less than satisfactory and thus noted the problem with the identification Y1 (Y=yes; 1=shot #1).

Row 03 illustrates an optional note made by the player that the problem on Row 02 with the shot was caused by a "pull."

Row 04 (Hit F/G Y/N) illustrates that yes (Y) the player's tee shot landed in the fairway.

Row 05 (Club Used) illustrates that a 1-Iron (1) was used for shot #1, a 2-Iron (2) was used for shot #2, and a Pitching Wedge (W) was used for shot#3.

Row 06 (Dist 1) illustrates that the distance remaining to the center of the green after shot #1 was 228 yards. The player obtained this distance as explained below.

Row 07 (Dist 2) illustrates that the distance remaining to the center of the green after shot #2 was estimated by the player to be 106 yards.

Row 08 (Putt 1) illustrates that the distance of the first putt was 30 feet.

Row 09 (Number Putts) illustrates that the player took one putt to complete play of the hole.

During play the golfer refers to existing yardage markers which are provided on most courses to measure the distance remaining to the center of the green. This measurement clarifies a key concept in using the system, which on each shot until the player reaches the green is: "How far is my ball from the center of the green?" (This concept is modified slightly on par 5 holes over 475 yards. Where necessary on par 5 holes, the player or player's caddy will pace (measure) the distance of the drive and note the distance on the scorecard with an identifying "T", i.e. 237T, to indicate the shot was measured 237 yards from the tee. When the data is entered into the computer system, on holes over 475 yards, the system will provide a graphic reference line of 200 yards from the tee for the player to use in placing the location of the tee shot.)

Normally on most holes, the golfer will note the location of each shot relative to the nearest yardage marker by either stepping off or estimating the variance from the marker. This is a common practice by most proficient golfers anyway, and thus does not alter a golfer's traditional habits and concentration which is so important and vital to good performance in competitive golf.

The scorecard of FIG. 1 is specially printed for use with the present system; however, this scorecard is not a requirement of the system. A standard scorecard (not shown), available at any golf course, can easily be modified or adapted for recording the data illustrated in FIG. 1.

DESCRIPTION--FIG. 2--COMPUTER

Normally, at a convenient time following the actual round of golf, the data on the sample scorecard is entered into a computer system which has been programmed to perform the functions discussed below.

A computer 81 (FIG. 2) having a keyboard 82 and a display monitor 80 is programmed with thirty-one mutually interrelated programs and units which perform all of the functions described and are included in the appendix of this application in the form of microfiche. The complete object codes of these programs appear in the microfiche appendix. These programs and units are written in the Pascal programming language, compiled on the Borland Pascal Compiler, version 7.0, including the Borland Graphics Interface, and may be run on a personal computer with hard disk storage, having an MS-DOS operating system, version 3.2 or greater, with a mouse or trackball and VGA display capabilities.

To initiate or start the system, at the "C:.backslash." prompt of the MS-DOS operating system, a player types: "cd.backslash.GOLF." This instruction means: "Change the directory on disk drive "C" (The hard drive) to GOLF." This instruction changes the prompt to "C:.backslash.GOLF>."

The player again types "GOLF" which will bring up the main menu on Screen 80. Main menu 80 illustrates the functions of the master program which controls all of the programs and units in the system and allows the player to selectively choose operations.

When an operation is completed the system automatically returns to The main menu to allow the player to continue with other selections or exit to the DOS operating system (line 83 of menu ) .

The system is programmed in two versions to accommodate a color or a black-and-white display.

When the main menu appears on the display a highlight bar is superimposed over the first or top item on the menu. The highlight bar, indicating desired selection, may be moved to other selection items by either moving the mouse or using arrow keys (not shown on keyboard 82)

Item 25 ("INSTRUCTIONS") provides a menu (not shown) of instructions as to how to proceed and operate the system.

A player will initially proceed by selecting menu item 20 ("INFORMATION ON GOLF COURSES PLAYED"). This item is selected by moving the highlighting bar over this menu selection; and, when the mouse button is pressed or the ENTER key (not shown) is pressed, the computer will display another menu which includes the item ("ENTER DATA FOR A NEW COURSE NOT IN DATA BASE"). Selection of this item provides specific instructions regarding the information that must be entered about each golf course played. Information about a specific course being played, such as name of the course plus distance and par for each hole, is normally printed on a standard scorecard (not shown) for the course. Taking the information from this standard scorecard, the player enters into the system through keyboard 82 the name of the course, plus the distance and par score for each of the eighteen holes. Normally, this information is entered only once for each set of tee boxes for each golf course. Then it is retained by the system and is available for future use. However, the distance for each hole can optionally be entered after each round to allow for normal, minor changes of tee box markers. The system can accommodate course measurements from several tee boxes, as is common to most golf courses, i.e., Championship Tees, Regular Men's Tees, Ladies' Tees, etc. For each round the player enters an identification number, date, comments, and course name.

The player next selects item 21 ("ENTER DATA FOR A ROUND OF GOLF") from the main menu. The system then guides the player sequentially, hole by hole, through an eighteen-hole round of golf. To facilitate data entry, the system asks the player on each hole to respond to the following requests presented sequentially in the same order, as illustrated in the sample scorecard (FIG. 1):

1. ENTER NUMBER OF STROKES (incl. PENALTY STROKES) TO REACH GREEN #1. For example, Row 01 (FIG. 1) illustrates that "3" should be entered through keyboard 82 (FIG. 2).

2. IF YOU HAD A PROBLEM ON THIS HOLE--SAND, BAD LIE, OBSTRUCTION, HAZARD, PENALTY, OR POOR SWING, SELECT YES or NO.

If YES is selected, the system brings-up a screen in which the player must identify the number(s) of the stroke(s) with a problem, i.e., 1st Stroke, 2nd Stroke, etc.

Then the system brings up a screen which asks the player to select the most applicable description for each problem shot from the following selection menu: Correctable swing, Sand/bunker shot, Behind tree/obstruction, Hit tree/obstruction, Bad lie or heavy grass/rough, Out-of-bounds or lost ball, Lateral or water hazard, Uneven lie, Penalty stroke.

For example, Row 02 (FIG. 1) indicates a problem with the first shot and that a selection should be made. Optional selection of "Correctable swing" will bring up a screen which asks the player to select the most applicable description of the shot pattern: Fade, Draw, Push, Pull, Slice, Hook, Push Slice, Pull Hook, Fat, Thin, Stub, Top.

Row 03 (FIG. 1) illustrates that Pull should be selected. (This information is used for analysis purposes.)

After the foregoing information is entered, or if NO is selected, the system moves on to the next request.

3. DID TEE SHOT HIT FAIRWAY OR GREEN--SELECT YES or NO. For example, Row 04 (FIG. 1) illustrates that YES (Y) should be selected.

4. ENTER, IN SEQUENCE, THE CLUB USED FOR EACH STROKE (NOT incl. PUTTS) ON THIS HOLE. A penalty stroke is identified on this screen and is treated the same as a club selection. A menu of club selections is presented to the player. Row 05 (FIG. 1) illustrates that the 1-Iron (1)should be selected first followed by selections of the 2-Iron (2) and the Pitching Wedge (W).

5. ENTER NUMBER OF PUTTS FOR HOLE. Row 09 (FIG. 1) illustrates that "1" should be entered.

OPERATION--FIG. 3A--SCREEN A--UNIVERSAL HOLE

After entry of the above information for each hole, the system will automatically display the screen illustrated in FIG 3A, which represents a first view of a universal golf hole. Hole number 18 and yardage of hole 19 are automatically displayed. Because the length of each hole was previously entered, Screen A will allow for the length of any golf hole from the center of a green 11 up to 700 yards measured to the back of a tee box 13. Fairway 12 represents a fairway width 16 of 100 yards; this is sufficiently large to simulate the width of any fairway.

A player using the system will quickly realize the important factor of accurate representations and calculations of distances, especially in accomplishing the object of determining club distance achievements. No attempts are made to depict bad lies from contour of the land, or exact locations of trees and sand traps, etc. Such variances are provided for under the menu selections previously illustrated. In other words, if a tee shot lands in a sand trap (not shown in the fairway), the player selects Sand/Bunker Shot from the menu for the next shot (the shot used for getting out of the bunker) to identify the problem. Also, if the player is in a rough which is only 25 yards from the center of the fairway and the player had a problem with the shot, the problem can be identified as Bad Lie or Heavy grass/rough similar to the Sand/Bunker Shot described in the previous sentence. Regardless of where the shot is illustrated on the screen, the system is designed to accommodate the many variances common to the game of golf.

Most golf courses have 250-, 200-, 150-, and 100-yard markers 10 on each fairway indicating the distance from the marker to the center of the green. As also indicated, during actual play, the player records, by either stepping off or estimating the distance from the nearest marker after each shot, on the data card of FIG. 1, the remaining distance in yards to the center of the green for each shot until the green is reached. In accordance with the current rules of golf which, for handicap purposes, limit the player to a maximum of eleven strokes per hole, the system allows a maximum of seven shots to reach the green and a maximum of four putts.

As illustrated in FIG. 3A, a green 11 is always located near the top of the screen. A fairway 12, between the green and tee box 13, will adjust its length, measured in yards, from the center of the green to the back of tee
