Wearable eye trackers

How do you analyze data captured with the glasses?

You can use Glasses Explore, our cloud-based software, to analyze the data from the glasses recordings. With this user-friendly interface, you’ll learn to find patterns, interpret gaze data, and share insights efficiently. Perfect for human performance analysis and consumer and UX research.

For more advance or academic research, you can analyze data from the glasses with our platform Tobii Pro Lab  Analyzer. Here, you can replay the videos, see where participants looked, and analyze the data in detail. There are several ways to analyze your data, such as using "Areas of interest", "Time of Interest", and by marking certain events. It is also possible to compare results across recordings and export this data for further analysis, either using statistics (quantitative) or exploring patterns (qualitative) in other software.

To generate heat maps from a Tobii Pro Glasses' recording, you first need to map the gaze data from the recording to a snapshot taken of the part of the recording that you wish to map. Then you will generate a dynamic heat map on this static image using "Assisted Mapping". 

It depends on the length of the video to be mapped. If you use our supportive function "Assisted Mapping" then it usually takes one minute to map 1 minute of recording. The mapping also requires a high-quality snapshot on which to map the data. 

It depends whether you are running a qualitative or a quantitative study. We recommend a sample of 6-10 participants for a qualitative study and a sample of 20-30 participants for a quantitative study. If the purpose is to publish the results, a sample size calculation is required to make sure the design and sample size has a chance to provide significant results. 

 In our Tobii Getting Started Program you will get personal (online) training tailored for your specific use case, which will guide you to an efficient and cost-effective study set-up. 

The ideal sampling frequency depends on your research question. For studies focusing on fixations (where participants look for a certain duration), 50Hz can be sufficient. However, if you want to capture faster eye movements (like saccades or smooth pursuit), a sampling rate of 100Hz is recommended. 

With a full battery you can make recordings of up to 90 minutes. There are three batteries in the set. If you need to make recordings longer than 90 minutes, please consider using an additional power bank. 

No, your participants cannot use their own glasses underneath the Tobii Pro Glasses 3. Instead, we offer a range of corrective lenses , which can be attached to the Tobii Pro Glasses 3.

Yes, you can do it before you start recording using the Tobii Pro Glasses 3 Controller Software. Note that once the audio has been turned off, the audio for the recording cannot be recovered later.
