What eye tracker should I choose for my research?

Tobii Eye Tracker 5 and 4C are eye trackers for designed for gaming and are not compatible with the research analytics platform Tobii Pro Lab uses to analyze eye tracking data. If you need eye tracking to understand gaze data about human behavior (e.g., with access to eye tracking metrics and visualizations like heat maps) then you’ll need a research graded eye tracker like [Tobii Pro Spark](/en/main/products/eye-trackers/screen-based/tobii-pro-spark), [Tobii Pro Fusion](/en/main/products/eye-trackers/screen-based/tobii-pro-fusion), or [Tobii Pro Spectrum](/en/main/products/eye-trackers/screen-based/tobii-pro-spectrum).

Why can’t  I use my Tobii Eye Tracker 5 or 4C for my research? 

You can analyze data from our screen-based eye trackers with our software [Tobii Pro Lab](/en/main/products/software/behavior-research-software/tobii-pro-lab/).  

Tobii Pro Lab is used to design experiments and collect eye tracking data. It offers visualizations of your eye tracking data in the form of heat maps and gaze plots. Tobii Pro Lab also allows you to specify which kind of data you would like to export for further quantitative or qualitative analysis. 

How do you analyze data from the eye trackers? 

There is no one-size-fits-all answer to the ideal sample size of an eye tracking study. It depends on your goals and the type of study you are running. We recommend a sample of 6-10 participants for a qualitative study and a sample of 20-30 participants for a quantitative study. If you plan to publish your results, a sample size calculation is required to make sure the design and sample size has a chance to provide significant results. 

In our training [Tobii Getting Started Program](/en/main/products/consulting-services/training-and-education) 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.

What is the appropriate sample size for my project / use case? 

The sampling frequency required for your project depends on the type of eye tracking data you are looking to collect. If your experiment only considers fixations, then 60 Hz will be adequate. If you are looking to accurately capture saccades as well, a 120 Hz eye tracker is recommended at the lower range. If you are an academic customer who requires high specificity of your data, then you might want to consider at least a 600 Hz sampling rate. 

What sampling rate is suitable for my research?  

Our modern and high-end eye trackers can capture gaze data from participants regardless of their glasses. There are, however, some limitations to this. It is not recommended that participants wear glasses with more than one power, i.e., bifocals, trifocals, or any kind of progressive glasses. The design of the lenses in these glasses makes it hard for the infra-red light of the eye trackers to correctly hit the center of the pupil. 

Some of my participants will need to wear their glasses during the study, can they still participate? 

It depends on the stimuli you use for your study. If you use the website feature, then all participants' recordings are being aggregated automatically, and hence you will have access to the heat map right after a participant finishes a study. If you are using a screen recording function, then the time to map the gaze data will depend 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 one minute of eye tracking recording. 

When purchasing our [Tobii Getting Started Program](/en/main/products/consulting-services/training-and-education) you will get personal (online) training tailored for your specific use case, it will guide you to an efficient way of setting up your study to save time and cost.
