Training devices for trajectory-based sports

A trajectory detection and analysis method, comprising:

• capturing, with a camera, images of a ball launched by a participant of a sports activity along a trajectory during a shot of the ball toward a goal within the sports activity, wherein the ball travels along the trajectory and reaches the goal from a launch point for the shot;
• analyzing the images with at least one computer;
• determining, with the at least one computer, a plurality of locations of the ball along the trajectory based on the analyzing;
• predicting, with the at least one computer, a portion of the trajectory of the ball based on the determined locations before the ball reaches the goal for the shot;
• predicting, with the at least one computer, an outcome of the shot at the goal based on the predicted portion of the trajectory before the ball reaches the goal for the shot, wherein the outcome is one of a made shot or a missed shot;
• and
• outputting, with a feedback interface, information indicative of the predicted outcome before the ball reaches the goal for the shot.
