Integration of SMI Eye Tracking systems

The SMI iView X™ Software Development Kit (SMI iView X™SDK) allows integration of the SMI remote and specialized eye tracking systems with popular stimulus presentation software (e.g. MATLAB,  including Psychophysics Toolbox, PST E-Prime®, Python, NBS Presentation®) and custom applications written e.g. in C/C++ and .NET.

The SMI iView X™ SDK enables these applications to easily remote control the eye tracker and receive real-time data from the eye tracker by using a network-based communication interface.

High and low level functions with sample code

The SMI iView X™ SDK contains an Application Programming Interface (API) consisting of  high-level (e.g. “calibration” and “tracking visualization”) and low-level functions (e.g. “get data”).

The extensive user manual provides a detailed description of more than 30 functions and ready-to-go sample code for a constantly increasing number of stimulus software products and programming languages.

Remote control and synchronization

The SMI iView X™ SDK allows a stimulus software or custom application to remote control and to synchronize with an SMI Eye Tracking system:

  • Calibrate/validate the eye tracking system including visualization of the results
  • Start/stop the experiment, and store the recorded eye data and separate trials
  • Synchronize with the stimulus software through real-time messages

Access to real-time data and visualizations

The SMI iView X™ SDK provides access to real-time eye data and online tracking status information, thus supporting the implementation of gaze-controlled applications and gaze-contingent paradigms:

  • Real-time binocular gaze data, pupil diameter, online fixation events
  • Low latency of eye data transfer
  • Online tracking monitor and live view of the eye image (for selected devices)
