Hardware Specifications

The SMI REDn scientific is a reliable screen-based eye tracker that enables researchers to conduct fixation based studies with a sampling rate of 30 or 60Hz. Unfortunately, this is no longer manufactured. Please see the Smart Eye Aurora as an equivalent substitute.

The SMI REDn Scientific eye tracker is compatible with the iMotions Screen-based Eye Tracking Module.

The iMotions Eye Tracking – Screen-based Module

Main features

With the iMotions Screen-based Eye Tracking Module, you can collect and analyze data in controlled lab environments using world leading, research grade trackers from hardware providers such as Tobii, EyeTech, Smart Eye, SMI, and Gazepoint. The Module allows for advanced analysis using tools such as heatmaps, gaze replays, and areas of interest (AOI) output metrics like time to first fixation & time spent. iMotions also provides automated gaze-mapping technology, in which gaze from dynamic environments is converted to static scenes for simpler aggregation and analysis.
