<p>The present invention provides a portable device that can be used anywhere and that enables a golfer to improve putting performance, for training or entertainment purposes. The device has an electronic analyzing system comprising, in one embodiment of the invention, only three passive infrared sensors to accurately detect all the crucial movements of a putter head (or any other golf club) (e.g., squareness at impact, speed, distance) throughout the crucial portion of a swing at the virtual point of impact (or actual point of impact if a golf ball is used). The device further uses these sensors to capture information in tandem with preset and/or selectable features and options (e.g., stimp, slope, statistics, games) to supply a holistic approach to putting practice. The device may also be equipped with an accelerometer/inclinometer to instantly inform the user of the slope and drop of the ground on which the device is placed.</p> |
