Technical Examples
A training aid for practicing a golf swing. Two laser pointers are mounted at opposite ends of a bar that is affixed to a hat. The laser pointers are horizontally and vertically adjustable and are adjusted such that the laser beams from the two laser pointers cross at a desired point in front of the user. While maintaining the proper stance for a golf swing, the beams are adjusted to intersect each other a short distance above the golf ball. Any movement of the head will cause the beams to shift. This provides immediate feedback to the user and is useful in training the user to execute a golf swing while keeping the head in a certain position and motionless.
