Hi, I am hoping to use the Pupil Labs (https://pupil-labs.com) eye tracking software with a usb connection to MonkeyLogic as a cheap alternative to the existing eye tracker. It seems like I can subscribe to the data stream and send it out in python msgpack (https://msgpack.org/) format. I was wondering how to interface this transfer with MonkeyLogic and whether the messages will need to be converted to a MatLab format before they are sent or whether that could happen within the MonkeyLogic framework.

The USB is for the connection between their camera and software, not for the distribution of data. They use the ZeroMQ library (https://docs.pupil-labs.com/#network-plugins), so you need to build a ZeroMQ client (msgpack is just a way to pack the data you ship on the network protocol). Enabling communication between two processes is not a new problem. I think the summary on the ZeroMQ website may help you understand what you need to do (http://zguide.zeromq.org/php:chapter1#toc12). If you want your code to be incorporated in NIMH ML, you need to provide it as a C/C++ library.
