Understanding how people engage with systems

Measuring human intuition, interaction, and improvements in design is key to understanding the human element when using and developing systems. Eye tracking helps us to see how humans are engaging with each system, machine and process.

Why use eye tracking?

Eye tracking is a scientific research methodology used to understand human cognitive abilities and behavior as humans are interacting with systems, devices, vehicles, and objects or events in the surrounding environment. Eye tracking methodology is also used for research purposes to understand, for example, the behavior of engineers, programmers, or physicians while analyzing technical systems and during problem solving.

What you can measure with eye tracking

Our solutions capture and analyze human-system interactions to deliver objective measurements and behavioral insights for use in design and ergonomics, for example, as well as developing usability, efficiency, and safety features. Eye tracking data can be extrapolated into:

  • Visual attention

  • Attentional allocation

  • Cognitive load and engagement

  • Judgement

  • Decision making

Unannounced Evacuation Experiment in a High-Rise Hotel Building with Evacuation Elevators: A Study of Evacuation Behaviour Using Eye-Tracking

Mossberg and colleagues (2021) used Tobii Pro Glasses to study evacuation behavior in a high-rise hotel building. The glasses were combined with Tobii Pro Lab to collect data on where participants are looking at to gain information before and during the evacuation. The study results showed that people fixate their gaze on the evacuation signage more often and longer when it is reinforced with a green flashing light.

Correlation Between Physiological and Performance-Based Metrics to Estimate Pilots' Cognitive Workload

Hebbar and colleagues (2021) combined Tobii Pro Glasses 2 and EEG recording to develop a non-invasive technique to estimate pilots’ cognitive workload. The researchers measured pupil size variation and gaze metrics as a proxy of mental workload during different levels of task difficulty and lighting conditions.

Analysis of Drivers’ Eye Movements on Roundabouts: A Driving Simulator Study

Azimian and colleagues (2021) combined Tobii Pro Glasses 2 and Tobi Pro Lab software to record drivers’ eye movements on roundabouts under distracted and non-distracted conditions. The study results showed that cell phone-induced distraction leads to less caution when approaching roundabouts, as indicated by drivers’ fixation duration decrease on the road, and an increase of the pupil size.
