Handheld golf course distance computer for automatically computing distances to sequentially selected points
First Claim
1. A self-contained handheld golf course distance computer for use by a player while playing a round of golf on a particular golf course, the computer comprising:
- keyboard input means for enabling the player to enter one or more commands into the computer;
memory means for storing routines and subroutines of instructions to be performed by the computer in executing commands entered by the player and for storing alphanumeric and graphical information regarding each hole of said golf course;
computing means, coupled to said keyboard input means and memory means, for selectively executing the routines and subroutines of instructions to be performed in executing commands entered by the player; and
liquid crystal display means for displaying the stored alphanumeric and graphical information regarding a selected hole of said golf course, said display means including a displayed cursor for enabling the player to designate a particular position on a graphical display of a selected hole;
said computing means being responsive to entry of a hole command entered by the player for causing said display means to selectively display said alphanumeric and graphical information regarding the selected hole, said computing means being responsive to entry of one or more cursor commands from said keyboard input means, during display of said graphical information regarding the selected hole for positioning said displayed cursor at an initial cursor position corresponding to the player'"'"'s present position on the selected hole, said computing means thereafter being responsive to entry of a distance command from said keyboard input means for computing a distance from said initial cursor position to a predetermined point on said selected hole and for causing said computed distance to be displayed on said display means, and said computing means thereafter being responsive to sequential repositioning of said displayed cursor at any number of new cursor positions for automatically computing and displaying, each time said cursor is repositioned it a new cursor position a distance from said initial cursor position to the new cursor position.

Abstract
A handheld golf course distance computer includes a graphics display and keyboard and is preprogrammed, using an external personal computer and optical data link, with alphanumeric and graphical information regarding each hole of a particular golf course. The alphanumeric information includes an identification of the course and a selected hole, information relating to hazards and/or the best method of play of the selected hole, the distance of play from various tees, the number of strokes required to par the hole, and typical playing time for the course. The actual or elapsed playing time from the beginning of play is also displayed. The graphical information, including details of the course terrain, is obtained from an aerial photograph of the course and converted to pixel information using commercially available personal computer software. The alphanumeric and graphical information associated with the selected hole may be selectively displayed. The distance between the player'"'"'s location on the hole, as represented by the position of a cursor in the display, and the center of the green is computed and displayed. The distance between two locations on the hole, as represented by original and subsequent cursor positions, may also be computed and displayed.

9. A process for enabling a player to compute the distance between any two locations on a hole of a golf course, the process comprising the steps of:
-
storing a graphical scaled map of the hole in a computer memory; displaying said graphical scaled map to the player; positioning a displayed cursor to an initial cursor position on the displayed graphical scaled map that corresponds to a current location of the player on the hole; computing, in response to a distance command, a distance between the initial cursor position and a predetermined location on the hole; automatically displaying the computed distance; subsequently sequentially positioning said displayed cursor at any number of new cursor positions on the displayed graphical scaled map; computing a distance, each time the cursor is positioned at a new cursor position, between said initial cursor position and the new cursor position; and automatically displaying the computed distance between said initial cursor position and the new cursor position.
