Optodrum
This tool is intended to be used in order to check and train the optokinetic reflex.
ATTENTION: If you have epilepsy don't use this tool as it can pose a risk to you
Usage
You can increase the speed by tapping on the right half of the screen, and decrease it by tapping on the left side.
There are many ways of using this tool, so feel free to experiment with it. One way of using it is by holding your device up to your eyes, so that most of you view is obstructed by the optodrum. Then you can do for example balance exercises, or film your eyes whilst looking at the screen to assess your OKN.
