What is eye tracking used for? Exploring real world use cases

Eye tracking 101 series - #9

Eye tracking has come a long way from its early days in psychology labs. Today, it’s a practical, powerful tool used across industries to understand human behavior in ways that traditional methods simply can’t.

Whether the goal is improving patient safety, designing more intuitive products, or understanding how shoppers make decisions, eye tracking provides the missing layer of insight: What people actually pay attention to. 

We explore some of the most common problems eye tracking helps solve across different industries and how organizations use Tobii’s screen‑based and wearable solutions to get there. 

Healthcare & medical research

Understanding attention in complex environments 

Healthcare environments are busy, dynamic, and often unpredictable. With so many visual elements competing for attention, even the best‑trained professionals can miss critical details. 

Eye tracking helps improve areas such as:

• Identifying the causes of diagnostic errors 

• Improving the design and layout of operating rooms 

• Assessing how clinicians manage information overload 

• Training students in clinical decision-making 

Screen-based eye trackers like Tobii Pro Fusion are commonly used for medical image interpretation studies, helping researchers understand how radiologists navigate X-rays and CT scans. 

For real‑world clinical research, Tobii Glasses X captures natural gaze behavior during simulations, emergency situations, and routine procedures, without interfering with the workflow. 

Outcome: Healthcare teams gain deeper insight into how experts actually see and process information, leading to better training, safer procedures, and improved patient outcomes. 

Automotive & transportation 

Making movement safer 

In transportation, attention is everything. Whether it’s a commercial driver, pilot, or commuter behind the wheel, even brief lapses can have serious consequences. Driver and flight simulators offer a controlled way to study attention and behavior, helping ensure training builds skills that transfer effectively to real‑world driving and aviation.

Eye tracking addresses challenges such as: 

• Understanding driver distraction and cognitive load 

• Evaluating new dashboard interfaces and ADAS alerts 

• Improving training for aviation, rail, and maritime operators 

• Studying behavior in autonomous and semi-autonomous vehicles 

Wearable eye tracking is especially valuable in this industry because driving and piloting tasks can’t be simulated effectively from a chair. Tobii Glasses X allow researchers to record gaze behavior during real driving, while Tobii’s automotive‑grade eye tracking technology, Tobii Autosense, is used by OEMs to develop in‑vehicle monitoring systems. 

Outcome: Manufacturers and regulators gain objective evidence to design safer interfaces, policies, and in‑vehicle technologies. 

Consumer research & retail

Seeing products through the shopper’s eyes 

Even the most experienced marketers can't always predict what shoppers will notice, ignore, or explore. Eye tracking offers a clear window into the decision‑making process, revealing what actually influences a purchase. 

Eye tracking helps retailers and brands understand: 

• Which products shoppers see and which they overlook 

• How shelf placement affects attention 

• Which package designs are easier to find 

• How people navigate physical and digital stores 

• What elements improve or hinder the path to purchase 

In controlled settings, screen-based eye trackers like Tobii Pro Spark provides high‑precision gaze data for detailed packaging tests. For in‑store research, wearable eye trackers help teams monitor natural shopping behavior without interrupting it. 

Outcome: Brands reduce guesswork and optimize packaging, store layouts, and marketing materials based on real, unbiased attention data. 

UX & human‑computer interaction 

Designing intuitive digital experiences 

Digital experiences succeed or fail depending on how easily users can find what they need. Eye tracking supports UX teams by revealing where interaction friction occurs, often before users are even aware of the issue themselves. 

Eye tracking brings clarity to:

• Identifying confusing navigation paths 

• Highlighting distracting or overlooked UI elements 

• Comparing competing design concepts 

• Measuring visual load in complex dashboards or software 

• Validating accessibility and readability 

Screen‑based eye trackers like Tobii Pro Fusion paired with Tobii Pro Lab are widely used by UX researchers because they integrate smoothly into think‑aloud testing, concept evaluation, and A/B design workflows. For unmoderated and large‑scale studies, Tobii Sticky complements this by enabling UX teams to test designs remotely and understand visual attention across broader user samples.

Outcome: UX teams build cleaner, more intuitive interfaces based on objective evidence rather than assumptions. 

Education & training 

Improving learning and skill acquisition 

From early childhood education to advanced technical training, understanding how learners absorb information is essential for building effective teaching strategies. 

Eye tracking helps address questions like: 

• How do students visually process complex information? 

• What differentiates expert from novice performance? 

• Which elements of a lesson or simulation need redesigning? 

• Can instructors detect where learners struggle in real time? 

Wearable eye tracking reveals how individuals perform hands‑on tasks, while screen-based systems help researchers study reading behavior, problem‑solving patterns, and attention distribution in learning materials. 

Screen‑based eye trackers such as Tobii Pro Fusion are well suited for
education and learning research, where studies often take place in schools, training centers, or other institutions. Their portable setup makes it easy to bring eye tracking into classrooms and labs, enabling precise analysis of reading behavior, problem‑solving strategies, and attention distribution across digital learning materials.re instructional design can be improved.

Outcome: Teachers and trainers receive actionable insights to improve content, instruction, and feedback.

Sports performance 

Refining the skills that separate elite athletes 

Elite athletes often “see the game” differently than amateurs, literally. Eye tracking helps coaches and sports scientists decode these differences. 

Eye tracking supports: 

• Understanding visual strategies in fast-paced sports 

• Training athletes to recognize key cues 

• Improving anticipation and decision-making 

• Designing better practice environments 

In sports research, wearable eye trackers are essential. Tobii Glasses X allows athletes to train naturally while researchers analyze gaze behavior frame‑by‑frame using Tobii Pro Lab. 

Outcome: Teams optimize performance using insights that can’t be captured through video review alone.

Manufacturing & industrial workflows 

Reducing errors and improving efficiency 

In manufacturing or assembly environments, small errors can create big production bottlenecks. Eye tracking highlights where workflows break down or where attention is misplaced. 

Typical challenges eye tracking helps solve: 

• Identifying steps where operators hesitate or miss critical cues 

• Improving the design of tools, displays, and instructions 

• Enhancing safety protocols 

• Supporting onboarding and training for new staff 

With Tobii Glasses X combined with Glasses Explore software, researchers can record tasks on the factory floor and evaluate gaze behavior without interfering with operations. 

Outcome: Manufacturers improve processes, reduce risk, and boost productivity across teams. 

Turning attention into actionable insight 

Across every industry, organizations turn to eye tracking for the same core reason:  
It provides objective, unbiased insight into human attention and behavior. Whether you're designing safer cars, more intuitive software, or more effective learning environments, the ability to observe what people actually see — not what they say they see — is transformative. 

From high‑precision screen‑based systems to naturalistic wearable trackers, eye tracking equips you with the clarity and confidence to turn human attention into actionable insight.
