Definitions
- the present invention is directed to a portable electronic device designed for improving an individual's performance with respect to playing golf by providing visual support for course strategy, club selection, shot approach, and analysis of an individual's playing characteristics.
- the present invention is also directed to a small electronic device which provides a detailed analysis of an individual's playing characteristics through the generation of individual long term golf records and statistics.
- the electronic scorecard is programmed with yardage and par values for each hole of the golf course. Once play has begun, the scorecard is changed to the play mode wherein the golfer inputs stroke values for each hole of the golf course individually for each player. After these values have been inputted, the electronic scorecard enables the player to selectively display accumulated par and stroke values for each individual golfer or preselected holes.
- Martz et al. discloses an electronic device which functions as a golf scorecard, this device does not adequately provide enough information to the golfer so that the golfer can substantially improve the golfer's game. The device merely provides the golfer with the yardage of each hole being played and keeps a running total or individual scores for the previously played holes. Thus, the device disclosed in Martz et al. cannot adequately aid the golfer in improving performance.
- the golf yardage indicator automatically selects the proper club for the golfer's next shot wherein the selection is based upon a standard performance for each individual golf club. In other words, the indicator may choose a five-iron every time the distance is approximately 150 yards, notwithstanding the actual individual characteristics of the individual playing golf.
- the yardage indicator of Jones et al. would fail to recognize this characteristic of the individual golfer and thus suggest the wrong club to the golfer which in turn will detrimentally effect the individual's performance.
- Remedio et al. discloses a computer attached to a golf cart which graphically displays a layout of the hole being played by the golfer. Remedio et al. further discloses that utilization of the cursor allows the golfer to input the ball's location on the graphic display such that the computer can accurately calculate the distance between the ball and the pin. This device also informs the individual of the actual distance from the ball to the pin but relies upon the individual to make the actual selection of the next selected club based on the memory of the individual. Remedio et al. also discloses the utilization of a graphical display to inform the individual of the various features, obstacles, and hazards on the golf course. This further information can be utilized by the individual in determining the actual club selection.
- a disadvantage in utilizing this device is that the device requires the utilization of a golf cart when playing golf.
- this golfer's aid device is very limited in its utilization because a majority of golfers do not use a cart when playing.
- this device requires the golfer to remember the golfer's own characteristics for each club. This can be a difficult task for a person only playing occasional golf.
- Kro er discloses an apparatus for determining various parameters of the game of golf. More specifically, this device determines the remaining distance to the green and selection of the appropriate golf club for use by the golfer. Kromer discloses that this device stores the distance achieved in the past with the selected club to yield a statistical value useful in selecting clubs. By measuring directly the distance achieved by previously used clubs such that performance information is continually-—updated, the device of Kromer provides a current performance evaluation upon which club selection can be based.
- the distance which the golf ball was advanced on the previous stroke is measured by the utilization of sensor devices connected to the wheels of a golf cart or a pull cart.
- Kromer further discloses that the angle that the ball has travelled must also be inputted to determine the distance information.
- Kromer provides various forms of information to the individual playing golf
- this device has many drawbacks in not providing accurate information such that the individual can substantially improve play performance. More specifically, the device does not graphically display individual golf holes so that the golfer is aware of the various obstacles, features, or hazards along the golf course.
- the system utilized by Kromer to input the distance of the ball has a disadvantage.
- Kromer discloses that the location of the ball or the distance that the ball travelled is determined by sensors connected to the wheel of a pull cart or golf cart. Thus, Kromer determines the distance of the ball according to the distance travelled by the golf cart or pull cart. The utilization of such a system has problems in accurately determining the distance travelled by the ball.
- a common characteristic of the game of golf is a temporarily lost ball in the rough along the fairway. It is very common for golfers to travel up and down an area of rough to locate a ball which is nestled deeply in the rough.
- the device disclosed by Kromer to calculate the distance of the flight of ball, the distance between the position of the ball and the pin on the green based upon the distance travelled by the pull cart or golf cart can be easily miscalculated when a golfer is searching for a temporarily lost ball along the rough.
- the device of Kromer can easily convey incorrect distance information to the individual golfer.

- the electronic device 1 also includes an ON/OFF switch 8 and a data interface terminal 7.
- Information is input into the electronic device 1 in various ways.
- Information regarding the golf stroke history of the individual player or the graphical information relating to the specific golf course being played can be inputted via the memory card slot 6 illustrated in Figure 1 wherein the information is stored on portable memory cards.
- this information with respect to the course layout of the specific golf course being played or golf stroke history can be inputted through an input/output interface terminal 7 which allows a host computer to down load information into the electronic device and subsequently unload information from the electronic device. This information also can be loaded via any combination of the above terminals.
- Information regarding club selection, hole selection, and other golf parameters can be inputted through a keyboard 3.
- the cursor 5 displayed on the display device 3 can be moved in various directions in response to a cursor controller 4.
- FIG. 2 illustrates the block diagram of possible internal components for the electronic device which function in conjunction with each other to perform the various functions of the present invention.
- the electronic device 1 includes a central processor unit 10 which controls the graphical display on the display device 2 as well as the other functions of the electronic device 1.
- the electronic device 1 is powered by a power source which may be rechargeable batteries, batteries, or be supplied through a direct connection at a power terminal.
- Information is input to the central processor device 10 through an input/output (I/O) interface 12.
- the input/output interface receives information from the computer input terminal 7.
- the input/output device 12 controls the inputting of information to the central processor unit 10.
- a memory card 6 may also be used to input data.
- the central processor unit also receives information from the keyboard 3 which provides command signals to the central processor unit from the individual golfer.
- the electronic device 1 includes a memory 11 which stores all data required by the electronic device including the graphical layout of the specific golf course being played and the club performance history of the individual player utilizing electronic device 1.
- the club performance history may be stored in the memory as parameters for an ellipsoid wherein values for a center point (with respect to distance) , a major axis, a minor axis, and an angle are actually stored. With respect to these values, the performance history is created based on a statistical analysis of past performance.
- Each shot previously played is assigned a club value, a distance value, and a deviation value.
- the club value is a value corresponding to a club being hit.
- the distance value is a value corresponding to a distance travelled, and the deviation value is an angle of deviation formed by the line through a ball's previous location and the ball's present location and the line through a ball's previous location and a desired ball's location.
- a two-dimensional graph can be generated wherein the end location of the ball is (x',y') and the starting location is (0,0).
- the distance value is the distance between (x' , y') and (0, 0)
- the deviation angle is the angle created by the line between (x', y') and (0, 0) and the y-axis.
- the plotting of the various points will define a statistical area that can be defined, for example, geometrically by the parameters of an ellipsoid.
- a statistical representation can be stored using only four values; a center point, a major axis, a minor axis, and an angle.
- the center point can be the
- (x, y) coordinate representing the center of the ellipsoid with the origin being the starting location of the ball.
- the major axis and minor axis of the ellipsoid would define the statistical area of the shot's landing area, and the angle would be the variance of the center point from the y-axis with the origin as the apex.
- This statistical area can be created using any conventional technique.
- the present invention can include an option to allow the user to vary the sample, thereby providing another tool for analysis. For example, if the player has recently taken lessons, the operator can limit one sample to shots after the lessons and another sample to shots before the lessons to determine from the two statistical areas if there has been improvement in performance. For an ellipsoid, improvement would be reflected as a decreased in the angle, a smaller major axis or a smaller minor axis.
- the central processor can utilize these values to formulate the projected target area of the next shot wherein the center point represents the center of the target area and the major axis and the minor axis define the outer boundaries of the target area.
- This information can be stored for a variety of probabilities for each club.
- This memory 11 can be loaded with the golf club history as well as the graphical golf course layout through the input/output device 12. While the golf course is being played, the club usage history can be updated and can be downloaded, upon completion, to an external storage device, such as a personal computer through the input/output terminal 12.
- Figure 3 illustrates a small part of a flow chart of some of the various functions carried out by the present invention. More specifically. Figure 3 illustrates some of the utilization of the electronic device 1 during the course of playing a game of golf. Upon start up, the individual playing golf inputs the hole number which the individual is presently playing. For example, if the individual is initially starting to play eighteen holes, the individual would input hole number one as being the hole now presently being played at step 51.
- the electronic device Upon inputting the hole number, the electronic device, at step 52, displays on the display device 2 the hole layout, graphically. Next, the electronic device, at step 53, determines which function has been inputted by the individual golfer. Depending upon which function is inputted by the individual golfer, the electronic device 1, through the central processor unit 10 will carry out one of various sub-routines.
- the process proceeds to step 60.
- the central processor unit 10 determines whether the contour function is set to have the elevation with respect to the elevation of the pin. More specifically, the individual golfer can choose whether to have the contour lines associated with the location of the ball as being zero feet or the contour lines being associated with the pin with the pin being at zero feet.
- the central processor unit 10 calculates the contour lines with respect to the pin.
- the central processor unit 10 determines that the pin is not to be utilized as the reference elevation, the central processor unit 10 calculates the contour lines with respect to the ball being the reference elevation at step 62.
- the display screen 2 displays the contour lines superimposed on the graphical hole layout.
- the contour lines may be labelled either as plus (+) elevation or negative (-) elevation with respect to the reference elevation.
- the location on the ball on the graphical hole layout will be associated with a contour line labelled negative two (-2) .
- step 64 the process returns to step 53.
- the central processor unit 10 proceeds to step 70.
- the central processor unit 10 receives an input corresponding to a club selection and an input corresponding to the probability desired at step 71. From these inputs, the central processor unit 10, at step 72, determines the target for the selected club with respect to the inputted probability. It is noted that in one preferred embodiment of the present invention, the individual golfer can input a number of probabilities such that the central processor unit 10 at step 72 determines a number of targets with respect to each probability.
- the display device 2 Upon the execution of step 72, the display device 2, at step 73, displays on the graphical hole layout the target or targets with the proper labelled probability. These targets may either be arcs or ellipsoids. For example, if a number of probabilities are entered at step 71, the display device at step 73 will display a number of concentric arcs or ellipsoids which represent the various probability areas. Each one of these arcs or ellipsoids can be formed or shaded differently to correspond to the different probability areas. Upon completion of this probability function, the central processor unit 10 returns to step 53.
- step 53 the central processor unit 10 proceeds to step 80.
- the desired increment of the yardage arcs and the reference point are inputted at step 81.
- the central processor unit 10 determines the actual yardage arcs with respect to the defined increment and reference point. The central processor unit then controls the display device 2 to display the yardage arcs superimposed upon the graphical hole layout at step 83, thereafter returning to step 53.
- step 53 the individual golfer inputs the play function
- the central processor unit 10 proceeds to step 90.
- the individual golfer Upon selection of the play function, the individual golfer, at step 91, inputs the club used in advancing the ball and the central processor unit 10 tallies a stroke against the score of the individual golfer. After inputting the club used, the individual golfer utilizes the cursor control 4 to move the cursor to the exact location of the ball with respect to the graphical hole layout at step 92.
- the central processor unit 10 Upon inputting the club used and the location of the ball, the central processor unit 10, at step 93, calculates the distance travelled by the ball and the distance to the pin from the ball. The central processor unit 10 then stores the distance travelled with the club used at step 94 so as to maintain a complete golf club stroke history for future reference and analysis.
- the central processor unit 10 determines the next club utilizing the distance to go and the stored golf club history. Upon making this determination, the central processor unit 10, at step 96, displays the suggested club to be used for the next shot. After this information is displayed, the central processor unit returns to step 53.
- the central processor unit 10 may also use stored intrinsic characteristic information to evaluate which club is to be selected. The generation of this intrinsic characteristic information will be discussed in more detail below.
- Figure 4(A) illustrates information 21 on the display screen 2. More specifically, upon selecting the function to display the scores of all the players playing the round, the electronic device 1 displays, for each player, on the display screen 2 the number of strokes for each hole as well as the score for the front nine and the score for the back nine and the total score for all eighteen holes as illustrated by 21 of Figure 4(A).
- the electronic device 1 displays the individual strokes for the player utilizing the electronic device 1 as illustrated by item 22. More specifically, Figure 4(B) illustrates the electronic device 1 displaying the clubs utilized by the individual player for each hole as well as the score for each hole, the score for the front nine, the score for the back nine, and the total score for eighteen holes.
- the displaying of club usage can be chronological.
- Figure 5 illustrates the electronic device 1 displaying a possible menu for the present invention.
- This menu as illustrated on the display screen 2 by item 23, informs the user as to the functions associated with the manipulation of certain keys on the keyboard 3.
- the keyboard 3 may have certain keys dedicated to predetermined functions, thus, reducing the use of a menu.
- Figure 6 illustrates the electronic device 1 in the yardage marker function mode. More specifically, upon the input or selection of the marker function and the input of the increment between yardage arcs and reference point, the electronic device 1 will display the hole being played with yardage arcs superimposed thereon. As illustrated in Figure 6, for example, the yardage arcs represent fifty yard increments with the pin as the reference point. The yardage arcs are represented by item 23 of Figure 6.
- Figure 7 illustrates the information displayed when the electronic device 1 is in the probability function mode. More specifically, when the individual golfer selects the probability function mode and further inputs the club to be selected and the probability or probabilities desired, the electronic device 1 will display the probability target superimposed upon the graphical hole layout.
- the target is ellipsoidal shape.
- the outer ring 24 of the probability target area represents the outer boundaries of the ninety percent target area.
- the next inner concentric ring of the target area as illustrated in Figure 7 may represent the eighty percent area whereas the next inner concentric ellipsoid may represent, for example, the seventy percent probability area.
- Figure 8 illustrates the electronic device 1 in the contour function mode.
- the electronic device 1 displays the graphic hole layout with contour lines 25 superimposed thereon.
- contour lines 25 may be labelled with the approximate elevation of that area with respect to either the pin as a reference point or the location of the ball as a reference point.
- the present invention is an electronic device 1 with a keyboard or keypad 3 and a pictorial display 2.
- the electronic device 1 is loaded before playing a golf course with data and individual player's handicap as well as an individual's golf club stroke history.
- the present invention displays the course and player's data while recording detailed player information.
- a player's score can be downloaded to the club's handicap system wherein an individual scorecard can be printed.
- Individual golf course information is loaded before playing a course to have the pictorial information and data for each hole on the course.
- the course layout can be easily updated to show tournament placements, temporary hazards, repair areas, tee area changes, and pin placements, etc.
- This data can be downloaded from a computer at the golf course's pro-shop or from a data disk which can be loaded individually into the electronic device 1.
- the generation of this course data can be realized by any conventional electronic mapping method which is capable of electronically mapping terrain characteristics of a selected area so that the terrain can be graphically displayed.
- individual handicap data Prior to starting a round of golf, individual handicap data may be entered as well as data relating to the type of game being played; i.e., "Best Ball”, “Scramble”, “Wolf”, or “Skins”, etc.
- the players individual handicap and home course slope rating is entered to accurately assign a handicap per hole.
- team pairing and other handicapping adjustments can be entered.
- One feature of the present invention is the accurate presentation of the situation for any hole with respect to the next shot and giving the exact distance to the pin. This feature enables the speeding up of play by eliminating the need for walking off distance to markers and allowing the golfer to carefully analyze the individual holes prior to play.
- the individual golfer Upon starting any given hole, the individual golfer inputs the hole number and a map of that hole is graphically displayed on the electronic device 1. After each shot, when the golfer gets to the ball's location, the golfer records the club just played and moves the cursor on the display to the ball's new location. The golfer pin-points the location of the ball on the display by referencing the various prominent course features displayed on the screen. Upon inputting the new location of the ball, the present invention stores this information and displays the remaining distance to the green and the strokes used so far. If the exact location of the pin is not downloaded prior to play from the pro-shop, as soon as the green can be readily seen by the player, the pin placement on the green can be entered through the utilization of cursor control.
- the present invention After input of the location of the ball into the electronic device, the present invention utilizes the distance remaining to the pin and analyzes the golfer's golf club history stored in the memory to determine which club the golfer should utilize in making the next shot.
