Webcam Eye Tracking

Webcam Eye Tracking is a software created by The BMS Lab. Researchers and Students at the University of Twente can create an explorative experiment in order to track the eyes of their participant through a webcam. Within the Webcam Eye Tracking experiment, the Researcher or Student can create several trials and analyze the results of all participants through a gaze plot and heat map plot.

Webcam Eye Tracking for Education #

At the moment, Webcam Eye Tracking is unsuitable for research because the data is not valid and reliable enough for data collection. So, it can only be used for educational purposes (i.e., explorative experiment). For example, researchers and students can exploratively try to see if there is a trend and understand the research methodologies behind Webcam Eye Tracking.

Best Practices #

To reduce potential issues and challenges, keep the following points in mind before using Webcam Eye Tracking as a explorative experment:

Planning Your Explorative Experiment Design #

  1. 1. Think about what you would like to measure? When? What will it deliver afterwards? And how does Webcam Eye Tracking fit within your explorative experiment. This helps you realize what you need to build, when and how much time it will likely take.
  2. 2. Take practical aspects into account: is there an easier way to do it? Uncertain? Ask the BMS Lab.
  3. 3. Consider the limitations of the software to your study. Keep in mind that Webcam Eye Tracking is only for educational purposes and is in continuous development which means that bugs might be introduced as a result.

Developing Your Explorative Experiment #

  1. 1. Ensure that you have approximately 2 – 3 weeks to build your test. You might need to adapt your methodology based on Webcam Eye Tracking’s functionalities (see “Further Support” section).
  2. 2. Your introduction screen should adequately inform your participants.
  3. 3. Any time you make new additions, make sure to regularly test your explorative experiment from the participant’s perspective.
  4. 4. Duplicate your explorative experiment to have a clean back-up version.
  5. 5. Test your final version as a participant.
  6. 6. Download your data metrics to ensure that the data output fits with your explorative experiment.
