On-site research without hardware

Local webcam eye tracking enables researchers to conduct eye tracking studies on‑site using standard computers and webcams. It offers a software‑only approach for controlled research environments, fully integrated within Tobii Pro Lab. 

On-site research without hardware

Accessible eye tracking for researchers

Local on-site webcam eye tracking enables researchers and educators to run screen-based AOI-level studies without dedicated eye tracking hardware. It runs entirely within Tobii Pro Lab, giving you full control over experiment design, data collection, and analysis.

Accessible eye tracking for researchers

Flexible for on-site research  

Conduct structured eye tracking studies in controlled environments without relying on dedicated hardware. Local webcam eye tracking gives researchers a flexible and accessible way to design, manage, and scale studies while maintaining full control within the Tobii Pro Lab workflow. 

  • Runs on standard computers with webcams.  

  • Supports full experiment design and analysis in Tobii Pro Lab.  

  • Scales easily across multiple workstations.  

  • Suitable for teaching, training, pilot studies, and applied research  

  • Supports research into attention, perception, and behavior.  

  • Delivers a consistent Tobii workflow and analysis experience.
