The iTrainer samples thousands of sensor readings a second and uses the information to construct a spatial image of the golf swing in 3D as well as the dynamics of the swing.
The iTrainer samples the following sensors 1000 times per second (or higher):
The sensor data is filtered and used in various combinations to determine the following:
- Club Lie angle – the front-to-back angle between the club shaft and the ground when the club is stationary
- Club face direction – the direction in which the clubface is aiming with respect to magnetic North
- Hand press – the side-to-side angle between the club shaft and ground
- Attack angle – the club shaft angle at the time impact is detected
- Shaft orientation – the instantaneous orientation of the club shaft in 3D space
- Swing Tempo – the relationship between the backswing time and downswing time, represented in Tour Tempo or CoreTempo format
- Club head speed – the estimated club-head speed at any instant in time.
- Launch angles – the calculated horizontal and vertical angle at which the ball leaves the face of the club
- Ball speed – the estimated ball speed in miles per hour based
- Spin rates – the estimated ball backspin and side spin rates at launch
- Ball Flight – the calculated vertical and horizontal ball trajectory including estimated carry, bounce and roll distance under typical conditions
