Combining multiple sensors and software tools extends the set of methods in a variety of research fields. Eye tracking adds unique value by providing objective, real-time information of a user’s visual focus and behavior. Objectives and scenarios for combining modalities are diverse.
Neuroscientists combine SMI Eye Tracking with biometric data for research on brain functions or neural disorders. Computer engineers implement SMI gaze control in brain computer interfaces. Psychologists add eye tracking to cognition experiments in external stimulus software. Virtual reality specialists incorporate real-time gaze interaction in 3D environments. Experts in neuromarketing/neurousability study shopper and user engagement.
SMI provides a wide range of tested and proven integrations.
SMI Eye tracking solutions are versatile to be connected with leading partner solutions in labs, virtual reality and in real world settings through –
- Plug&play data integration modules and dedicated partner export templates for SMI software
- SMI SDK for real-time access of eye movement and pupil size data with ready-to-go sample code
- Dedicated plugins for LSL and leading partner solutions (Biopac, Brain Products, g.tec, Qualisys, WorldViz…)
- SMI interfacing tools such as TTL trigger and messages, StimTracker for SMI)
SMI plug&play modules
With SMI plug&play modules for SMI Experiment Suite software, Emotiv EPOC EEG data and the Index of Cognitive Activity (ICA) by Eye Tracking, Inc. are automatically synchronized with SMI Eye Tracking for easy analysis in SMI BeGaze software.
TTL trigger and messages from SMI software
SMI solutions support the sending, receiving and logging of up to eight TTL trigger and of flexible software messages in parallel. This allows for online and offline synchronization of SMI Eye Tracking with other data streams in external software, e.g. in the EYE-EEG plug-in for EEGLAB.
SMI Software Development Kit
All SMI Eye Tracking systems come with a Software Development Kit (SDK) for real-time access of eye movement and pupil size data. The SMI SDK contains an API consisting of several high-level and low-level functions as well as ready-to-go sample code (e.g. for C/C++, C#, Matlab, Python, Unity).
StimTracker for SMI hardware
Timing in the submillisecond precision range can be achieved with the StimTracker for SMI by Cedrus Corporation. The device sets common time stamps for connected physiological devices which makes it an excellent multichannel synchronization tool.
Lab Streaming Layer plug-ins for SMI
The Lab Streaming Layer (LSL) offers plug-ins for many biometric, motion tracking and human interface devices. With the tested LSL plug-ins for SMI, researchers can integrate SMI Eye Tracking data in challenging multimodal experiments and brain computer interfaces.
SMI VRPN interface
A special module allows to combine SMI Eye Tracking Glasses with leading head and motion tracking solutions via the Virtual Reality Peripheral Network (VRPN) standard.
To facilitate the use of SMI Eye Tracking with partner solutions, SMI worked with partners to implement plug-ins in partner software (Biopac, Brain Products, g.tec, Qualisys, WorldViz…)
