Definitions

  • the present disclosure relates to motion detection systems, and more particularly to a method and portable electronic device for golf swing detection for scoring assistance.
  • a golfer can easily and often lose track of how many strokes a player has made at a given hole.
  • Conventional golf stroke counters use indexing wheels which are advanced through a range of index positions by depressing a corresponding button which engages the wheel and which rotates it from its current index position to the next index position.
  • a first indexing wheel is provided for counting holes (the "hole wheel”) and a second indexing wheel is provided for counting strokes (the "stroke wheel”).
  • conventional golf swing counters require user interaction at each swing (by depressing the button) and the resetting of the device at the start of each new hole.
  • resetting the hole wheel or stroke wheel may require the player to depress the button until the corresponding indexing wheel has made a full rotation and returns to its starting (e.g., 1 or 0 stroke) position.
  • the hole and stroke wheels each have nine or ten index positions with are marked or others indicated as values 1 to 9 or 0 to 9, depending on the number of index positions.
  • the maximum number of golf strokes counted by the golf stroke counter may be greater than or smaller than that being used by the players. For example, if a maximum stroke count of 6 or 7 is being used, the player may have to depress the button 3 or 4 times to reset the stroke wheel. This sometimes results in "over-pressing" in which the player accidental advances the stroke wheel beyond the starting index position. If no maximum stroke count is being used by the players or a maximum stroke count of 10 or more is being used, a player with ten or more strokes may have to keep mental track of this fact since the stroke wheel typically only provides one place holder, resulting in a maximum stroke count of 9 on the device.
