Abstract
The techniques and systems described herein track gaze movement of a user while eyes of the user read a document on a computing device. The techniques may then analyze or evaluate the gaze movement to determine if a reading interruption occurs (e.g., a reading pause or irregularity in a regular reading rate for the user). The reading interruption may occur when the user, while reading, encounters or notices a problem in the text. The reading interruption may also occur when the user encounters or notices text that the user has a strong interest in. When the reading interruption occurs, the techniques may evaluate a gaze direction and associate the reading interruption with a text that is currently displayed (e.g., word, sentence, paragraph, page, etc.). Moreover, the techniques may map the displayed text to a location in the document (e.g., a page or other identifiable section), and report the location to a centralized entity where statistical analysis can be performed to determine if there is a problem in the document.
