You need a SPINSIGHT ball with dots to use the spin measurement.
The "SPINSIGHT beta" App on android is a development prototype and we recommend users to use our iOS-App on the iPhone.
To get started with the SPINSIGHT beta App under Android do:
- Install the App
- Only available to a limited audience.
- Requires registration.
- The App will ask you to read and accept our privacy agreement and for permissions to use the camera.
- On most smartphones you need to "Run Tests" to adjust the camera settings before you can start the measurement.
- The app needs good light for high speed video measurement.
- >300 Lux for low speed
- >600 Lux for high speed
- Check the light level at your table with "Measure Light Level"
- Use SPINSIGHT balls.
- Select "SPINSIGHT ball" for the ball type.
- Select "150 rps" for the measurement range.
- Place the phone in a phone stand next to the table.
- Recommended is about 130-170 cm height above the floor and 20-100 cm distance from the table.
- Place a SPINSIGHT ball behind the centerline of the table about 10cm from the net.
- Start the measurement in the app.
- The App will try to detect the ball and adjust the ISO value.
- For better results check and adjust the ISO value and focus.
- Play some long serves over the center of the table through the measurement area.
