A system for providing a virtual caddy includes a caddy module, the caddy module configured to and executing code to receive a current ball location and a desired ball ending location. The caddy module further configured to access a database of swings with a plurality of clubs and resultant ball trajectories captured by a launch monitor. The caddy module further configured to analyze the database of swings and ball trajectories to determine a suggested club.

A method for measuring spin of a golf ball includes obtaining at least two images of the golf ball after a golf club contacts the golf ball. The method also includes identifying the time span between the obtained at least two images to create a numerical time difference, defining an outline of the golf ball while the golf ball is in flight, finding at least one marking on the golf ball in each golf ball image, finding the rotations of the golf ball by aligning the at least one marking on the golf ball in each golf ball image, and converting the rotations of the golf ball into spin values by combining the rotations and the numerical time differences, wherein the spin values comprise at least a spin axis and a rotation angle. The spin values may then be displayed to a user.

In one embodiment, a method for training a golfer and providing a Swingscore includes, tabulating a plurality of model player data sets for a plurality of clubs to create a tabulated plurality of model player sets. The method further including capturing a user player data set for a plurality of clubs. The method further including comparing the user player data set of the plurality of model player data sets. The method further including determining a Swingscore based on the comparison. In one configuration, the Swingscore is determined by comparing two positions of a set of ten positions of the user player data set to corresponding two positions of the tabulated plurality of model player data sets.

As system for determining the trajectory of a sport object propelled via an implement includes a sensing module executing code and configured to determine launch characteristics of a sport object upon being launched. The system further includes a trajectory module executing code and configured to calculate a D-plane for an implement that struck the sport object based on the launch characteristics; and determine a trajectory for the sport object based on the launch characteristics and the D-plane.

Systems and methods are provided for predicting the club path, the face to path and the face to target of a golf club during a golf swing. Preferred embodiments include a sensing module executing code and configured to determine launch characteristics of a sport object upon being launched by the golf club. Preferred embodiments also include a trajectory module executing code and configured to record a plurality of golf swings, comprising at least a known club path, face to path and face to target value. The club path, the face to path and the face to target of the golf swing can then be predicted based on the launch characteristics and the recorded plurality of golf swings.

A system for determining the trajectory of a sport object propelled via an implement using a single mobile device includes a single mobile device and a sensor in the single mobile device. The system further includes a swing radius module, the swing radius module calculating a swing radius of an implement swung by a user. The system further includes a notification module, the notification module providing a notification to the user that the swing radius is outside of a viewing frame of the sensor.
