Definitions

  • the present invention relates to electronic and data processing apparatus for simulating a game of golf. More particularly, the apparatus senses golf club movement just before it hits a simulated golf ball in order to predict where on an actual image of a preselected hole terrain it would land with tolerable accuracy. More particularly still, the simulated golf ball, when hit, rotates around a substantially vertical axis, whereupon its speed of rotation may be sensed to aid in the prediction of where an actual ball would land. Furthermore, the present invention relates to a method of representing an actual preselected golf course by photographic or the like means for later display to the user of the apparatus. More particularly, the selected golf terrain is partitioned in segments, each segment is photographed, the photographs are digitized and stored on laser video disc for retrieval and display as a game is played.
  • the attitude of the club head at impact is determined by two sensors spaced along the club face in front of the simulated golf ball to permit evaluation of swing in terms of "square", “open” or “closed” attitude.
  • the club attitude and swing direction are used for deriving an assessment of the flight characteristics of the ball.
  • the swing direction and club attitude are also indicated to the player.
  • the rate of swing of the club between predetermined points is timed by a clock that operates at variable pulse rates.
  • the clock rate is automatically selected in accordance with the computed flight characteristic computed for the same swing.
  • the clock rates are selected such that the resulting digital output is an appropriate measure of the distance in yards.
  • United States Patent 3,769,894 issued November 6, 1973 to Robert M. Konklin entitled Golf Game teaches the steps of building a model of a golf hole on a reduced scale, the model having a flat playing surface, and photographing the playing surface from differing points on the model. Scenes illustrating portions of the gold hole are displayed to the golfer on a screen on which a spot of light is projected on the displayed scene where computations predicted the ball's trajectory.
  • United States Patent 4,429,880 issued February 7, 1984 to Richard M. Chen et al discloses a Golf Game Simulator Device which permits the golf player to view a specific golf course or portion thereof on a television monitor and is provided with additional information relating to the lie of ball and its position in relation to the hole.
  • the golfer then hits the ball in the normal manner, which ball is fixedly retained on a joystick apparatus, whereby in striking the ball the joystick transmits signals to a computer which generates graphic data relative to a golf course and converts the signal input to graphic display information relative to the new position or lie of the ball in relation to the hole on the golf course.
  • the golf ball is mounted so that when struck, first and second signals for each of four degrees of movement are transmitted to the computer and correlated with the golf course data input.

  • Player 90 receives input from computer 213 and selectively display video information, such as a video image of an actual golf course 230 on screen 221.
  • Disc 91 and cassette 280 are of course coordinated so that generated images are of the same subject matter.
  • the specific tee location or lie of the ball will have a corresponding view or pre-recorded scene on video disc 91.
  • the computer may first generate graphic information relative to the lie of the ball and then instruct the video player to freeze frame the disc 91 to demonstrate the actual vantage point of the golfer as if the golfer were actually positioned on the course at that ball location.
  • Pre-recorded images on the disc 91 may be at various point locations on the golf course spaced on a grid layout of several meters apart.

  • the magnet 32 is embedded in the cylinder above the shaft 27 at the same level as the magnet 30.
  • the upper part of the cylinder 33 in addition to housing the magnets 31 and 32 embedded therein, also serves as a braking surface against which a brake pad 35 is pressed by means of lever 36 which is actuated by solenoid 37 in order to stop rotation of the cylinder (and the ball 26) around the shaft 28 once the ball 26 has been hit by a golf club swinging player (not shown).

  • the centers on each horizontal line are fifteen yards apart, so that every rectangle is fifty-by fifteen yards.
  • the apparatus would display a photograph taken from the respective center in the direction of the hole 103. Therefore, in photographing the fairway 101, a photograph is taken from a center such as 109 looking at the hole 103.
  • the putting green 104 and surroundings are partitioned into three concentric areas: an outer circle 111 of fifty yards diameter, a circle 112 of 35 yards diameter, and a smaller circle 113 of 15 yards diameter.
  • a photograph looking at the hole 103 is taken from points on the circles 111 to 113 at 45° intervals.

Accordingly, there are twenty-five photographs around the hole 103, while in the example of Figure 10 the fairway 101 yields twenty-eight photographs, for a total of fifty four photographs including the one from above, typically, per golf hole.
  • the fairway 101 is video taped and the single video frames are each assigned an address. The full golf course, if so desired, is mastered on tape and then remastered on video disc. Video taping and mastering is available from CTI Communications of Saskatoon, Saskatchewan, Canada. Transfer on video disc is available from the 3M Company, U.S.A. The stored frames are later retrieved for display by means of their address on the video disc.
  • a particular frame is retrieved for display as computations reveal that the hit by a golf club of the simulated ball 26 would have landed a hypothetical ball within the confines of rectangle 115 centered around the center 109.
  • a further randomising computation would yield a random position of the lay of the hypothetical ball 117 in the vicinity of the tree 116.
  • the apparatus would display the appropriate frame while the graphics and overlay generator 53 would display a splash 119 in the water trap 118.
  • the player is prompted by a screen message to stand on the right hand side of the top surface 21 in order to obtain a reference reading of the players weight by means of the strain bridge 74 located underneath. Changes in weight relative to the reference reading, which are registered by the strain bridge 74 during swing action, are recorded and provide swing analysis information to the player later on if requested.
  • the player is prompted by a screen message to indicate a choice between right handed and left handed swing by touching the appropriate area on the display screen 24. This will determine which of the two printed circuit boards 43 and 44 will be the primary operative board and the software is configured accordingly.
  • the interaction between the player and the machine continues via screen prompting and messages to which the player reacts by making a choice. For example, since the player is using actual golf clubs to hit the ball 26, an array of standard golf clubs is displayed to the player where a choice is indicated by touching the screen to select a club identical to the one that the player will actually use.
  • the BALL HIT signal starts the ball timer 73, while the shadow crossing of the shaft 27 of SF4 for left-handed swings and SF18 for right-handed swings stops the ball timer 73. Otherwise, if no ball hit is indicated, a false swing is indicated after approximately sixty-five mS, for example when the player is merely addressing the ball.
  • the default aim point is the hole 103.
  • the player may do so by requesting the overall view of the fairway 101 to be displayed and by touching the screen at the chosen aiming point.
  • the change in aiming direction is then accomplished by the system with simple coordinate transformation through an appropriate software routine.
  • Each of the phototransistors SF0 to SF22 in the front row 39 corresponds to one bit in the three-byte word transferred, where a ONE indicates that the corresponding phototransistor is under the golf club's shadow. Because the PC boards 43 and 44 are identical, as mentioned earlier, data for the right hand swing is transferred with the phototransistor SF22 nearest the player; while data for a left hand swing is transferred with the phototransistor SF0 nearest the player.
  • the bit number 23 in the three-byte word does not correspond to any phototransistor, but toggles between ZERO and ONE once every sampling. The toggle bit serves as an error checking bit in the programming to ensure that the information is being transferred correctly.
  • DMA transfers continue every nine clock cycles until the ball is hit with the bytes stored in consecutive memory locations in a 60K DMA memory buffer, the pointer of which, once the buffer is full, is automatically reset to the top of the buffer. This "wrap-around" continues until the ball 26 is hit as indicated by the photosensor 47.
  • a DMA buffer size of 60K bytes, it is possible to measure club swings as slow as approximately .5 miles per hour.
  • the DMA buffer memory will contain several thousand successive frames or "snapshots" of the profile of the club's shadow as it passed over the front row 39.
  • club parameters such as club velocity, horizontal approach angle, impact positions, face angle, and vertical approach angle. The computation of this parameters will now be discussed with particular reference to the flow chart shown in Figure 11.
  • the club shadow is analyzed to give a snapshot of the leading edge of the club as it crosses the front row 39 in the form of an array giving the time of crossing for each sensor relative to the time of crossing of the first sensor crossed. From the leading edge array the position of the club as it crosses the front row 39 can be calculated as well as the club face angle.
  • the horizontal approach angle Haa is computed as follows:
  • the club face angle Cfa is computed as follows:
  • the vertical approach angle Vaa is computed as follows:
  • the eyeview calculation which yields the address of the picture to be retrieved from video disc player 54 is explained with particular reference to Figure 14.
  • the calculation of the eyeview for a given location on the golf course is determined from three arrays.
  • the first of these defines the areas on the course for which a particular eyeview will be displayed. It is a two dimensional array which defines a sequence of up to 12 contiguous intervals (i.e. rectangles such as 115 in Figure 10) for each screen row 105 to 108. It is of the form Xmin[Row,i] where 0 ⁇ Row ⁇ 191 and 1 ⁇ i ⁇ 12.
  • the entries in this array are the left hand endpoints of the intervals.
  • the second array defines the eyeview number for each of the areas defined by the Xmin array.
