result = PsychOpenEyes(cmd, handle [, arg1, arg2, …]);

PsychOpenEyes controls Psychtoolboxs built-in computer vision based eye
tracker, based on the free-software open-source “OpenEyes” toolkit.

Syntax: result = PsychOpenEyes(command, handle, optional arguments…);

‘command’ is a subcommand, similar to the subcommands in Screen() and
other PTB functions.

‘handle’ A numeric handle to the tracker connection. Currently you should
just pass zero (0) as handle.

‘arg1, arg2, …’ Optional arguments for different subcommands.
