Game-changing wireless basketball shot tracker helps elevate player's game towards pro standard, and it’s affordable too

Feb 20, 2015
Oslo, Norway - 2015/02/20 - Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that U.S. startup, ShotTracker, is employing in its basketball shot tracker of the same name the multiple award-winning Nordic nRF51822 Systems-on-Chip (SoCs) with embedded ARM Cortex M0 microprocessors and 256kB of Flash memory to provide the Bluetooth® Smart (formerly known as Bluetooth low energy) wireless connectivity and part of the state-of-the-art motion-recognition processing.
In operation, ShotTracker can be used with any regular basketball and net and comprises three pieces: a water-resistant net sensor (with embedded nRF51822), a wrist-worn sensor or sleeve wearable (with embedded nRF51822), and a free partner app running on any Bluetooth Smart Ready smartphone or tablet.
These all synchronize to create a personal shooting profile for up to four separate users and help enable players and coaches to automatically track and analyze shooting skills (including shot attempts, makes and misses) in real time. All data is then pushed to the cloud and shareable on social media.
The intelligence of ShotTracker derives from a sophisticated, patent-pending software algorithm that analyzes data from a 3-axis accelerometer embedded into the net sensor (measuring movement of net and frame to detect makes and rim bounces and running standalone on the nRF51822’s ARM Cortex M0 microprocessor and 256kB Flash memory) and a 6-axis accelerometer embedded into the wrist wearable or sleeve (measuring roll, pitch, yaw, X-Y-Z motion plus G-forces and harmonic waves and running on the nRF51822 plus an external ARM Cortex M4-based microprocessor).
Using the collected data, the ShotTracker software algorithm is able to recognize up to four individual player’s shooting profiles – including jump shots – while eliminating any spurious ‘noise’ generated from non-shot-related movement such as dribbling, passing, catching, shot blocks, and pump fakes.
“The core philosophy underlying this product is: ‘you can’t improve what you can’t measure’,” comments Davyeon Ross, Co-Founder and COO of ShotTracker and former U.S. college basketball player who recalls routinely shooting up to 1,000 shots a day during his college training days.
Ross continues: “Our near-future product roadmap includes being able to have players situated in different countries challenge each-other in real-time, as well as the ability to simultaneously track up to 15-20 players, including their location on court when they shoot, from a single smartphone or tablet. Our ultimate mission is to run the basketball score board with immediate who shot, when, where, and how data.”
“We selected Nordic Semiconductor after looking at several different Bluetooth Smart chips and vendors,” continues Ross. “We felt that not only was the Nordic chip architecture and product maturity superior, but that its firmware development software gave us pretty much the plug and play simplicity we needed to focus on developing our application without worrying about the intricacies of the Bluetooth Smart wireless protocol.
“The ultra low power operating characteristics of the Nordic nRF51822 also enabled us to achieve a 3-month battery lifetime from the net sensor and 8-hours (continuous use) for the wrist and sleeve sensor from small, on-board 110V rechargeable batteries.”
