Fab, thanks! Do you know if these are backwards compatible with older versions of the API? If not, we should either make them optional orrrrr implement a version check. (The latter would have my preference.) |

I don't know whether it is backwards compatible, and I actually also don't know in which exact API version they introduced this function. I thought it was API 3.0, but I just found out I have version 2.8 (according to the get_api function call) and it works for me. From what I could find online, the blink tracking got introduced in version 2.1, and the more accurate pupil size in mm got introduced somewhere between versions 2.3 and 2.7. Documentation online is a bit sparse and scattered. |
