In modern society where time is of essence and almost everything is accessible with a click of a button, it is important that the information we take in is relevant, which is why automatized text summaries must contain necessary information and is understandable for the reader. This study aims to investigate if extracted and highlighted automatic text summaries are as comprehensive as the original text and the differences between extracted summary and highlight summary. The research will study the eyes movement during reading different types of texts, mainly focusing on fixation and saccades. The study found that readers tend to fixate more when reading summaries than an original text, which in turn lead to a longer time to read the text. For comprehensiveness there was no greater difference found between the summaries and the original text.
