Tobii Pro VR Integration
A retrofitted version of the HTC Vive headset with a seamless and complete eye tracking integration from Tobii Pro. This unique combination transforms the way studies are conducted and opens up new research possibilities.
Eye tracking studies in VR
The Tobii Pro VR Integration allows researchers to run eye tracking studies in fully-controlled virtual environments, easily repeat research scenarios and switch stimuli, all while keeping track of the participants’ gaze. Without compromising the VR experience, this research tool provides high-quality eye tracking data and tracks a vast majority of the world population.
Eye tracking in immersive VR is transforming how studies can be conducted, and it opens up entirely new research possibilities for professionals in fields such as psychology, shopper research, training, and performance assessment.
Powerful eye tracking solution
The eye tracking platform integrated into the VR headset is designed and tested to deliver robust, high-performance eye tracking at 120Hz for a majority of the world’s population, including tracking through most prescription glasses. The advanced slippage compensation handles movements of the headset and maintains the accuracy and calibration, allowing the user to move naturally during the experience without losing performance in eye tracking.
Seamless hardware integration
The Pro VR Integration is a retrofitted version of the HTC Vive headset. The eye tracking platform is incorporated directly into the headset, which ensures no interference with the user experience of VR. The proprietary Tobii EyeChip™ handles the data processing and puts a minimum load on the host CPU. No external cables are needed, because eye tracking data is transmitted via the standard HTC Vive cables.
Knowledge and skills transfer
In almost all high-skill tasks, it is very difficult for the expert to articulate exactly what separates his or her technique from that of a beginner. Using eye tracking to get visual outputs like gazeplots and heatmaps, you can quickly and easily compare the performance of a novice worker with a more skilled one. This will help you discover what is behind the best practices of the more experienced people on your team. You can turn their individual skills into the company’s knowledge so it can be transferred to new employees.
For multinational companies working overseas, eye tracking helps to bridge language barriers and transfer knowledge and skills in the most universally understood way – visually.
Powerful SDK to access eye tracking data
Eye tracking data can be accessed both live and for post analysis using Tobii Pro SDK and example code for Unity VR engine compatibility. The Pro SDK supports millisecond synchronization and allows researchers to build their own customized analysis applications.
