The instructions for it start in Russian I think, but half way down the page it’s in English. Read trough carefully because you have to copy a file from the eye x software to the folder that you are downloading witch contains an executable file that will open a small program. At first you select the device or eye tracker that you are using. In this case the eye x. Click on the tile and a window to the right of the screen will appear. There you will select if you want to double click, right or left click, scroll, it even has a keyboard. You will need windows 8.1 but I think older versions of the software work with windows 7. If you have any questions please ask.
