Eye event detection |
摘要 |
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. |

1. A method comprising:
receiving, at a computing device, a user selection of a document; displaying, on the computing device, displayed text of the document, the displayed text being displayed based at least in part on a first formatted version of the document; capturing, using one or more front-facing cameras of the computing device, a plurality of images of at least a portion of eyes of a user as the user reads the displayed text of the document; tracking, based at least in part on an analysis of individual ones of the plurality of captured images, a rate at which a gaze of the eyes moves as the user reads the displayed text of the document; determining that the rate at which the gaze moves is less than a reading rate of the user; determining a display screen location that contains a portion of the displayed text based on the determining that the rate at which the gaze moves is less than the reading rate of the user; associating the display screen location that contains the portion of the displayed text with an identifiable section within a second formatted version of the document that is different than the first formatted version of the document, wherein the identifiable section comprises a page; and sending, to one or more network-accessible devices, an indication that a reading interruption has occurred at the identifiable section within the second formatted version of the document. |
