The aim of this article is to present the possibilities of application of eye-tracking methodology in the research of interlanguage translation. The development of non-invasive methods for measuring eye motion and computer technologies allows researchers to record and analyze a huge volume of data that eye movement generates. Thus, eye-tracking research expands intensively. The fi rst part of the article presents selected types of interlanguage translation and the possibilities of their testing with a video eye-tracker. The second part of the article focuses on participants in video eye-tracking research
