Eye Movements and Eye Tracking
2019-10-24 Warsaw, Poland 2
- In front of a scene, a person's eyes move between points that capture their attention,
especially objects in movement, with which they manage to recreate a "cerebral image
- f the scene".
- Eye tracking is a tool to analyse the movement and behaviour of the eyes in the
presence of stimulus.
- Eye tracking allows to know the eye behaviours:
- It can give a possibility to analyse the fixation point of the gaze, the movement of the eyes in
relation to the head, and other types of eye movements.
- It can give us information about human behaviour in any environment to analyse preferences of
users.
- The standard model in eye-tracking studies is constituted by two concepts:
- Fixation: the moment in which the eyes remain fixed on an object and it is possible to appreciate
it in detail
- Saccades (or saccades movements): the rapid eye movements between two fixations.
Eye Tracking as a road safety research toolce
- Eye-tracking device for road safety research
- Well-established since 1970s.
- Stationary and mobile devices
- Recorded are:
- Gaze
- Fixation
- Fixation duration
- Saccade
- The systems of capture of eye movements are becoming
very relevant today:
- They allow us to extract objective data when a person looks
at a stimulus, in a specific situation
- They allow us to know where the person is specifically looking

Previous research work
- Two perspectives: driver and pedestrian
- Pedestrians:
- Zito et al. (2015) – old/ young pedestrains on unsignalized crossing, virtual reality
- Jiang et al. (2018) – young pedestrains on signalized crossing, outdoor
- Kurvers (2018) – young pedestrains on unsignalized crossing, simulator
- Biassoni et al. (2018) – children/ adults on unsignalized crossing, pictures
- Drivers:
- Chapman and Underwood (1998), Underwood et al. (2002), Konstantopoulos et al. (2010) –
drivers’ perception in different conditions, film video and virtual routes
- Ābele et al. (2018) – young drivers’ perception of adult and child on unsignalized crossings,
simulator
- Chen et al. (2019) – drivers’ recognition of pedestrian road-crossing intentions on unsignalized
crossings, video-based simulation
- Lack of outdoor

Case study plan
- Aim:
- General: to understand deeper drivers’ eye movements ahead of pedestrian crossings (and
to assess drivers’ behaviours towards different situations as well as relations “drivers vs.
- ther road-users”)
- Concrete: how do drivers scan pedestrian crossings?
- Technical background:
- Eye-tracking glasses: to analyze attention and focus of drivers
- Test field:
- Route in Olomouc (around 15 minutes driving time when taffic is free)
- Objects - pedestrian crossings
- Time and conditions of driving tests: October 2019, early in the morning (peak-hours)
- Sample of drivers: 9 drivers, 22-32 ages
- Work in progress

Field test - Route
2019-10-24 Warsaw, Poland 6
- General characteristics
- 38 pedestrian crossings
(from drivers’ point of view):
- 28 on mid-block section
(20 without traffic lights)
- 6 after turning right/ left
(4 without traffci lights)
- 4 on the roundabout
- Pilot study:
- C3, C4, C5
