(a) A participant, wearing the mobile eye-tracking head unit; (b) First camera recording the road scene during the drive; (c) Second camera recording the driver during the drive; (d) Calibration points; (e) Scene marker used for calibration.
<p>The subject has given written informed consent, as outlined in the PLOS consent form, to publication of their photograph.</p
Value range for (a) the average number of correctly collected items over all runs, (b) the average time needed to complete the supermarket search task over all runs, and (c) the average time (over all runs) per correctly collected item.
<p>The participant subgroups are marked by GCp/GPp (glaucoma controls/patients who passed), GPf (glaucoma patients who failed).</p
Comparison of the horizontal gaze distribution (HGD) towards the central 20° area of the visual field between patients who passed (Pf) and patients who failed (Pf); glaucoma patients who passed (GPp) and glaucoma patients who failed (GPf); and between patients with right-sided HVFDs who passed (HRp), with left-sided HVFDs who passed (HLp), and patients with HVFDs who failed (HPf).

Driving parameters with significant differences between glaucoma control subjects who passed (GCp), glaucoma patients who passed (GPp) and glaucoma patients who failed (GPf) the driving assessment.

The proportion of glances in percent (PGP) of patients with homonymous visual field defects towards the VFD during the on-road assessment.
<p>For each of the eight road scenes (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087470#pone-0087470-t001" target="_blank">Table 1</a>), the upper panel shows the PGP of each participant. The lower panel shows the corresponding VFD tested by binocular semi-automated 90° kinetic perimetry. The red line and the shallow red area represent the border and the extent of the HVFD, respectively.</p

The drug store corridor with all marked special-offer products (orange signs) on two racks (each containing six shelves).
<p>Two cameras (marked by blue circles) at the beginning and the end of the corridor were used to record navigation of the subjects during the task.</p
