Smart grip system helps cricketers improve their technique
June 5th, 2019—
When batting in cricket, applying the proper amount of force with both hands is critical; however, as a coach, it’s difficult to judge just how much is actually used. To assist with player improvement, researchers at the University of Auckland’s Augmented Human Lab have come up with a bat that senses the force exerted by each hand gripping the handle.
The augmented handle is covered with an array of force sensitive resistors, which push data to an Arduino Mega and then to a PC over Bluetooth. Direct vibrotactile feedback is implemented in a pair of smart wristbands, leading to better accuracy and confidence in swing technique.
CricketCoach is a smart system that creates awareness of the hand-grip force for cricket players. A custom Force-Sensitive Resistor (FSR) matrix was developed and attached to the bat’s handle to sense the gripping. Two wristbands, incorporating vibration motors, provide feedback that helps non-expert users to understand the relative forces exerted by each hand while performing a stroke. A preliminary user study was conducted to collect first insights. The results show that both, binary vibration, as well as vibration patterns, improved the execution of batting strikes significantly.
