What Equipment Do You Need for an Eye-Tracking Study?
Eye-tracking technology has become a powerful tool for researchers, marketers, UX designers, and educators. By analyzing eye movements, businesses and researchers can gain insights into human behavior, decision-making, and visual engagement. However, if you’re new to the field, you might wonder what equipment is necessary to conduct a successful eye-tracking study. In this article, we’ll break down the essential gear needed and introduce how Gazepoint’s products can help you get started.
1. Eye-Tracking Device
The core piece of equipment for any eye-tracking study is, of course, the eye-tracker itself. This device records eye movements, providing data on where, when, and how long participants focus on specific elements.
Gazepoint offers a range of affordable and high-quality eye-tracking systems that are ideal for different types of research, including:
- Gazepoint GP3 Eye Tracker: A versatile, entry-level option that provides robust tracking capabilities for general research and UX studies.
- Gazepoint GP3 HD Eye Tracker: Ideal for studies that require larger freedom of head movement and higher data rates, such as those in neuroscience and psychology.
- Gazepoint GP3 Mobile: A powerful solution for recording eye-gaze data on mobile devices such as smartphones and tablets.
These devices are designed to be easy to set up and use, making them accessible for both novice and experienced researchers.
2. Computer System
To run the eye-tracking software and store the collected data, you’ll need a computer system with a modern processor and sufficient memory. This system should have:
- Operating System: Windows (10 or later versions recommended)
- Processor: Intel i5 or higher (i7 for advanced studies with real-time analysis)
- Memory: 8 GB of RAM (16 GB or more for high-resolution video and data-heavy applications)
- USB Ports: At least two free USB port to connect the eye-tracking device
Most modern computers can handle these requirements, and Gazepoint’s software is optimized to work efficiently even on mid-range hardware.
3. Eye-Tracking Software
Eye-tracking data is only useful if you have the right tools to visualize and analyze it. Gazepoint provides Gazepoint Analysis, which is compatible with all Gazepoint hardware. This software includes features such as:
- Real-time gaze tracking and visualization
- Heatmaps and gaze plots for visual analysis
- Data export options to CSV for in-depth analysis in other tools
- Support for various stimuli formats, including images, videos, and websites
The software’s intuitive interface makes it easy to set up experiments, record sessions, and analyze the results without a steep learning curve.
4. Stimulus Presentation Tools
Depending on the nature of your study, you might need additional software to present visual stimuli to participants. Gazepoint devices integrate seamlessly with specialized tools such as:
- Psychopy (Python): An open-source option for building and running experiments
- MATLAB: For custom experiment designs and data analysis
- Lab-Streaming Layer (LSL): Open-source system for streaming, synchronizing, and recording various data streams acquired from diverse hardware.
These tools, along with Gazepoint’s own software suite, provide flexibility in designing and conducting various types of eye-tracking experiments.
5. Participant Setup and Environment Control
Creating a comfortable and controlled environment for your participants is essential for obtaining reliable eye-tracking data. To ensure optimal results:
- Lighting: Keep consistent, moderate ambient lighting with minimal sunlight that could interfere with eye detection.
- Positioning: Participants should sit at a comfortable distance (typically 60-75 cm) from the eye-tracker, with a recommended adjustable height chair for optimizing their position.
6. Accessories and Optional Equipment
To further enhance your study setup, you might consider the following accessories:
- Laptop / VESA Mounting: The Gazepoint GP3 and GP3HD can be mounted directly to the back of a display to reduce clutter on the table top. A laptop base is also available that spreads the device weight across the keyboard of a laptop to prevent accidently key presses.
- Recording Tools: If your study involves in-person interviews or qualitative analysis, a camera and microphone can be useful for recording participant reactions.
- Biometrics Tools: Additional biometric signals can be tracked with the Gazepoint Biometrics systems (heart rate and skin conductivity).
