Motivation What really happens when sport objects are
thrown/hit/caught? What control attributes affect accuracy,
distance? How can object data be repeatedly captured,
analyzed, and turned into useful feedback to players?
MEMS will provide the answer New accelerometers and gyroscopes are small and
tough enough to embed into sports equipment and measure event characteristics
Coupled with the right processor, software, and communication hardware, an unprecedented platform for data analysis emerges
Competitive Analysis
Very new area, only niche products RevFire Baseball/Softball
Measures RPM and pitch speed RF communication with handheld display unit Expensive, single-use battery, cannot withstand shock
Flying Tach Frisbee Measures RPM and flight time On-board display
No agnostic platform capable of multi-axis capture and analysis
Requirements
Multi-axis data capture Small, low-power design
Fit in almost any sport object Last for majority of period/quarter/inning/half
High Shock Tolerance Simple UI Reliable data capture, logging, and communication Wireless power and communication are highly desired
Hardware!
Processor Arduino Pro Mini 328
MEMS Sensors Invensense IDG-500 Dual-Axis Gyro Analog Devices ADXL-345 Tri-Axis Accelerometer
Memory MicroSD for up to 2GB storage Easy transfer to personal computer for offline analysis
Battery LiPoly for small size, high power density Inductive charging?
Future Directions
Profile sports to determine minimum data required -> less/cheaper parts, code efficiency, introduce real-time analysis & feedback
Create our own custom integrated PCB Smaller size, lower weight Lower cost, sports-specific solutions?
Truly wireless operation “Dock” with inductive charging and short-range RF
communication for data transfer Enables seamless embedding into sports objects
