Mobile eye tracking in the real world: Best practices

Area of Science:

• Cognitive Science
• Human Behavior Research
• Experimental Psychology

Background:

• Research on human behavior, particularly spatial navigation, is moving towards naturalistic settings.
• Virtual reality (VR) offers some benefits but doesn't fully replicate real-world environmental richness.
• There's a need for best practices in conducting experiments in complex, real-world environments.

Purpose of the Study:

• To demonstrate the feasibility of mobile eye-tracking in large-scale, outdoor urban environments.
• To collect high-quality data on natural behavior, including eye-tracking, head orientation, and GPS, with minimal constraints.
• To establish best practices for naturalistic research in complex urban settings, especially for spatial navigation.

Main Methods:

• Conducted a mobile eye-tracking study in an outdoor urban environment (Limassol, Cyprus).
• Enabled unconstrained, long-duration free exploration and outside-pointing tasks.
• Collected mobile eye-tracking, head orientation, and GPS data "in the wild".

Main Results:

• Demonstrated the feasibility of collecting high-quality behavioral data in a real-world urban setting.
• Captured a wide range of natural human behavior with minimal experimental limitations.
• Identified logistical and methodological challenges specific to complex, outdoor environments.

Conclusions:

• Mobile eye-tracking is a viable method for studying naturalistic human behavior in urban environments.
• Best practices derived from this study can guide future research in real-world settings.
• Establishing methodological standards will encourage more research on human behavior outside traditional laboratory settings.
