Eye-tracking study - offline vs. online

Imagine that you have to conduct a quantitative (N=80) eye-tracking experiment containing 20 stimuli with additional questionnaires presented after the test. There are two ways to achieve it:

The offline way

You're probably familiar with a Tobii, GP3, or any other hardware eye-tracker, so you know what to do: go to your laboratory (assuming there's no lockdown at the moment), set up the study, and invite the participants. Here's the tricky part: before getting to the actual data, you have to spend hours collecting the data, asking the participants to visit you offline, and repeating the same routine for all of them. After some time (let's suppose you can handle 8-10 participants/day, so after two weeks) - you have the beautiful sets of data to work with, and the exciting part, the analysis, can finally begin.

The online/remote way

You set up the study in a web-browser. Use RealEye or one of many online panels to invite participants by sharing the study link. The very next day, you have the beautiful sets of data to work with, and the exciting part, the analysis, can begin.

One thing is sure:

Eye-Tracking research, just like many other industries is moving online, and it's happening right now.

What's different? What's the same?

You can expect lots of similarities using an online approach: the metrics from an online study are very much the same for the hardware option. In RealEye, you get:

  • heatmaps (gaze- and fixation-based), per participant and, aggregated,
  • clicks and mouse movements,
  • AOI tool with all the standard eye-tracking metrics (Dwell, Fixations, TTFF, Total Time, Ratio, and more)
  • participants' gaze recordings,
  • CSV files with raw data or calculated metrics,
  • answers from additional questions,
  • results' quality statistic and data quality grades,

There are also several differences:

Offline
Participants environment
  • Laboratory
  • Their home
Requirements
  • offline laboratory
  • hardware devices
  • software license for data analysis
  • ability to invite participants to the lab
  • software license
  • online panel, can be a RealEye panel (read more)
Experiment duration factors
  • inviting and interviewing participants offline
  • collect results from dozens participants at the same time
  • collaboration using an on-line dashboard
Technical differences
  • "letter-size" accuracy
  • 60-240Hz
Costs
depends on chosen devices and the number of them, usually a couple of thousands USD Starting from $189 (learn more)

Frequently Asked Questions

RealEye studies are proven to be around 110 px accurate. This allows analyzing users interaction on a website with precision reaching the size of a single button.
We predict the gaze point with frequency up to 60 Hz.

For in-depth analysis of webcam eye-tracking accuracy check the following articles:

Either your own participants or RealEye testers. You can invite your users or panel and share the study with them using a participation link. All they need to have is a laptop/PC with a webcam.

We also have a network of panelists from all around the world - mainly from the UK and the US. Randomly picked users can be assigned to your task. They are called RealEye testers. We will not show them your stimuli before the test starts, so their interaction will be natural.

Note: RealEye participants can't take part in a 'Live Website' studies and studies longer than 10 minutes. Read more about the limitations here

There are only monthly payments, so there’s no possibility to pay per study. But keep in mind, that you can cancel your license any time (even in the same month) - you’ll keep the account access until the end of the billing period.
You can easily integrate the RealEye tool with external tools (eg. surveys), but also compare the results obtained from other tools using our CSV file (i.e. by the timestamp).
