This is an app that records eye movements during dizziness attacks. The movements of the smartphone placed in front of you are synthesized into the recorded video as an animation.
It checks the movement of your smartphone (pitch, roll, yaw) and notifies you with a beep or vibration when there is movement that exceeds the setting.
Gyro data information from your smartphone can be distributed via WIFI for the Windows CapNYS nystagmus recording software.
