Eye Trackers

Eye trackers are used at OPL to help distinguish ergonomic issues in the design process.  We use eye tracking systems from IScan, SmartEye, Polhemus, and SMI.  IScan and Polhemus are used for near eye displays.  These displays are worn on the head by the operator.  The IScan system is used to track the position of the pupil, and corneal reflections.  Polhemus must also be used with near eye tracking because it records the movement of the head.  Both the IScan and Polhemus systems have been engineered to fit in an orange box, which allows us to use the system in different enviornments. 

At OPL we also use optical tracking systems.  These systems consist of infrared cameras that are placed in various locations where they can record the subject.  The optical eye trackers require a large amount of image processing to determine the head position, orientation, and also the eye vectors.  We are currently using the SmartEye system for our optical tracking system.

To the left are a few examples of our Near Eye Displays.  At the bottom there is also the orange box that has been engineered to make the IScan and Polhemus portable.
