Slam Force Net Makes Its Debut
The Slam Dunk competition at the NBA All Star game (Feb. 25 at 8pm Eastern on TNT) will feature the Object-Based Media Group's Slam Force basketball net, which measures the energy of a dunk.
A basketball net incorporates segments of conductive fiber whose resistance changes with degree of stretch. By measuring this resistance over time, hardware associated with this net can calculate force and speed of a basketball traveling through the net. Applications include training, toys that indicate the force and speed on a display, “dunk competitions,” and augmented reality effects on television broadcasts. This net is far less expensive and more robust than other approaches to measuring data about the ball (e.g., photosensors or ultrasonic sensors) and doesn’t require a physical change to the hoop or backboard other than providing electrical connections to the net. Another application of the material is a flat net that can measure velocity of a ball hit or pitched into it (as in baseball or tennis), and can measure position as well (e.g., for determining whether a practice baseball pitch would have been a strike).
