Custom Eye-Tracking Sensors: How 3D Printing Enables Research

When researchers need specialized equipment, off-the-shelf solutions often fall short. That's where the MakerLab comes in. We recently collaborated with Jennifer Themanson, a faculty member whose research required a custom mounting solution for eye-tracking sensors.

The Challenge

Eye-tracking technology is crucial for research in psychology, human-computer interaction, and cognitive science. However, integrating these sensors into specific experimental setups often requires custom hardware. Commercial mounts are designed for general use and rarely fit the precise requirements of specialized research protocols.

Design and Iteration

This project showcased the full capabilities of our lab. Working from reference images and specifications provided by the researcher, our student designers created a custom mount from scratch. The iterative design process involved:

• Analyzing the sensor dimensions and mounting requirements
• Creating initial 3D models in CAD software
• Printing prototypes to test fit and function
• Refining the design based on feedback

The collaboration between our design team—including gurus Aidan and Arundhati—and the researcher ensured the final product met all specifications.

Why Custom Fabrication Matters

This project illustrates a broader trend: 3D printing is democratizing research equipment fabrication. Instead of expensive custom machining or compromising with ill-fitting commercial products, researchers can now work with makerspaces like ours to create exactly what they need at a fraction of the cost.
