Eye tracking technology offers valuable insights into how developers and users interact with software artifacts, tools, and interfaces. However, conducting empirical eye tracking research comes with a number of challenges. To assist researchers and students new to the field, this article provides a concise summary of the background as well as the key considerations. As an additional resource, we present a detailed checklist along with its application. Note that both the outline and the checklist are specifically tailored to, but not limited to, the context of software engineering research.
