Hi @hyeongsukryu, The MATLAB Bindings for the Tobii Pro SDK are part of the Tobii Pro business department.
This forum is intended for support with the Tobii EyeX and C4 Eye Tracker and associated SDK’s.
Please get in touch with Tobii Pro Support department directly @ http://www.tobiipro.com/contact/contact-support/ for an
answer to your query.
That being said, from the nature of the error message, it may be that you are using a Tobii 4C or EyeX tracker which require the purchase of special licence to work together with the Pro SDK.. if this is the case please get in touch with [email protected] for a quote.
Many thanks,
