Key Findings

01Daylight and plants are the most frequently studied biophilic elements using eye-tracking.
02Eye-tracking metrics like pupil size can indicate visual discomfort with daylight.
03Attention Restoration Theory is often applied to plant studies, with fixation duration as a key metric.
04Significant variations exist in eye-tracking devices, metrics, and experimental tasks across studies.
05Virtual reality is more prevalent in studies of plants than daylight.

Application

Design takeaway

How to apply

When designing spaces intended to incorporate natural elements, consider conducting or referencing eye-tracking studies to understand how users actually perceive and interact with these features, rather than relying solely on assumptions.

Project actions

01When exploring biophilic design, consider how you might measure user response objectively.
02If possible, investigate existing eye-tracking studies related to the specific natural elements you are incorporating into your design project.

Method & Evidence

AimTo systematically review and synthesize the application and efficacy of eye-tracking technology in evaluating biophilic design elements within built environments.

MethodSystematic Literature Review

ProcedureA structured search of academic databases (Scopus, Web of Science) was conducted using keywords related to eye-tracking and biophilic design. Identified publications were analyzed to collate information on biophilic elements studied, research designs, and theoretical frameworks. Findings were synthesized, and insights from related eye-tracking research were incorporated.

Strengths & Limitations

Strengths

+Provides objective, quantifiable data on user responses.
+Can reveal subconscious reactions and attention patterns.
+Applicable to a wide range of biophilic elements and environments.

Limitations

The cost and complexity of eye-tracking equipment can be a barrier. Interpreting eye-tracking data requires expertise, and results can be influenced by the experimental setup and participant factors.

Reliability & validity

Reliability can be enhanced through standardized experimental protocols and calibration of eye-tracking equipment. Validity is supported by the convergence of eye-tracking data with established psychological theories (e.g., Attention Restoration Theory) and subjective user reports.

Think critically

Given the variability in methodologies, how can designers ensure that eye-tracking data from different studies is reliably comparable when informing their design decisions?

Design Principles

"Quantify user engagement with natural elements using objective measures like eye-tracking to validate and refine biophilic design strategies."

Understanding user responses to biophilic design elements through objective metrics like eye-tracking can lead to more effective and user-centric design strategies. This data can inform the placement, type, and intensity of natural elements to maximize their positive psychological and physiological impact.

What This Means for Your Design

This research shows that using special cameras to watch where people look (eye-tracking) can help designers understand if people like or dislike natural things in buildings, like sunlight or plants, and how much attention they pay to them.
