Abstract
Myex is a Matlab interface for the Tobii EyeX eye-tracker. It allows Matlab users to receive incoming data from the eye-tracker, by providing a data buffer that can receive data from the EyeX, and be queried by the user on demand. Myex enables Matlab users to take advantage of low-cost, portable eye-tracking technology, ideal for use in gaze-contingent psychophysical paradigms, or for users looking to develop assistive devices for individuals with impaired mobility.
Highlights
Myex is a Matlab interface for the Tobii EyeX eye-tracker
Note that the code does not in any way modify or affect the data returned by the Tobii EyeX Engine, and Myex introduces negligible additional processing overheads and/or lag. (NB: the latency of any gaze estimate is determined primarily by any smoothing applied within the Tobii EyeX engine itself, and by the transmission speed of the USB connection:
