Abstract
We present SMITE, a toolbox for the measurement of eye movements using eye trackers manufactured by SMI GmbH. The toolbox provides a wrapper around the iViewX SDK provided by SMI, allowing simple integration of SMI eye trackers into Psychophysics Toolbox and PsychoPy programs. The toolbox provides a graphical interface for participant setup and calibration that is implemented natively in Psychophysics Toolbox and PsychoPy drawing commands, as well as providing several convenience features for, inter alia, creating gaze-contingent experiments and working with two-computer setups. Given that SMI GmbH and its support department have closed down, it is expected that this toolbox will provide owners of SMI eye trackers with an important new way to continue to create experiments with their systems. The eye trackers supported by this toolbox are the SMI HiSpeed 1250, SMI RED systems, SMI RED-m, SMI RED250mobile, and SMI REDn.
