This system helps shooters develop the muscle memory to consistently shoot the ball straight at a 45 degree angle and 11 inches deep, and ultimately make more shots and win more games. The Noahlytics Data Service provides detailed feedback on every shot taken and the unique grading system helps shooters understand which areas to focus on during a workout. Left-Right, Depth in the basket and entry angle are important measurements to help shooters understand why a shot was a miss or a make.

The Angle attribute is the angle between the plane at the rim and the tangent to the ball’s flight path at the rim. Then a straight line is drawn as a tangent to the ball’s flight path as it would cross through the plane of the rim. First the flight of the shot is recorded as the center of the ball is tracked during the flight of the shot forming a parabola. The front of the rim is still defined as the point on the rim closest to the shooter.Īngle is the entry angle of the shot into the hoop. The sensor measures the point where the ball flight parabola would cross the plane of the rim, with the front of the rim being 0 inches and the back of the rim being 18 inches. The curved portion of all objects is mathematically called an arc.If two points are chosen on a circle, they divide the circle into one major arc and one minor arc or two semi-circles. A straight shot would yield a reading of zero, verses a shot which lands centered exactly on the leftmost part of the hoop has a Left-Right value of negative nine inches, and a shot which lands exactly on the rightmost part of the hoop has a Left-Right value of plus nine inches.ĭepth is the point where the shot enters into the hoop in relation to the front of the rim. Arc Length Formula: A continuous part of a curve or a circle’s circumference is called an arc.Arc length is defined as the distance along the circumference of any circle or any curve or arc. The convenient user interface enables the easy measurement of lengths, angles and surfaces directly from the image. IC Measure provides powerful tools for the manual measurement of circles, lines, polygons and angles. The measurements are taken based off of the hoop’s nine-inch radius. Added new Measure-Tools: 3-Point-Circle, 3-Point-Arc, Line-Point-Distance, Rectangle Download: Octo2.0.0.133. This is measured dynamically with each shot by drawing an imaginary line from the shooter through the center of the hoop. The left-right measurement is the deviation of the shot either to the left or the right of dead center. Noah- 3 Measurements from Noah Basketball on Vimeo. For shots that contact the rim, the measurement is collected where the center of the ball would have intersected with the plane of the rim. The measurement is collected when the center of the ball intersects with the plane of the rim. These attributes are measured from the perspective of the shooter, so the point on the hoop closest to the shooter is always defined as the front of the hoop. In addition to tracking where the shot was taken and if the shot was a make or a miss, the three attributes of the shot that are measured are left-right, depth in the basket and entry angle. A sensor positioned 13 feet above the basket captures the position of the ball 30 times per second. The Noah Shooting System tracks shots taken anywhere on the court and collects data about how and where the shot enters the hoop.
