Tiny, tiny... rodents – some soft and grey, some brown with black stripes, in paintings, posters, wallcharts, thumb-tacked magazine clippings and poorly executed crayon drawings, hurling themselves fatally in their thousands over the cliff of their island home; or crudely taxidermied and mounted, eyes glazed and little paws frozen stiff – on every available surface.
Using an externally mounted eye tracking system, our study assessed saccades, fixations, overall time spent per radiograph, and the subjects' chosen bunion rating.
VR has also been defined as a simulated world, which comprises of some computer-generated images conceived via head mounted eye goggles and wired clothing – thereby enabling the end users to interact in a realistic three-dimensional situation (Yoh 2001).
The head mounted eye tracker, presented in Fig. 3, was mounted and manually calibrated with a 16 point grid.
Eye movement data were recorded with an SMI HiSpeed 240 tower mounted eye tracker (SensoMotoric Instruments, Teltow, Germany) (Fig. 2).
We used the Eyelink I head-mounted eye-tracking system (SR research) to record the gaze of the participants.
Eye movements were recorded from the right eye with an EyeLink 1000 desktop mounted eye-tracker (SR Research Ltd) with a sampling rate of 250 Hz.
Wearing a head mounted eye tracker system may restrict eye movements and head movements which may be confused with imposed restrictions by older subjects.
Two drivers with Parkinson's disease (PD) and six control drivers drove a fixed route in a driving simulator while wearing a head mounted eye tracker.
The subjects wore a head mounted eye tracker, Arrington ViewPoint Systems (35) shown in Fig. 3, while driving a fixed route in a PC-based STISIM fixed base driving simulator (36).
For whole mounts, eyes were fixed as above and washed with PBS directly after cSLO imaging.
