The reason is that abnormalities in oculomotor movements are usually symptoms of injuries in the nervous system. This paper presents a novel regulated solution named OSCANN. OSCANN aims at providing an innovative tool for the control, management and visualization of oculomotor neurological examinations. This solution utilizes an eye-tracker sensor based on video electro-oculography (VOG) technology to capture eye movements and store them in video files. Such a sensor can store images at a rate of 100 frames per second. A characterization study was performed using twenty-two volunteers (13 male, 9 female, ages 22\u201345 years, mean 29.3 years, SD = 6.7) to assess the accuracy and precision specifications of OSCANN during oculomotor movement analysis. The accuracy was evaluated based on the offset, whereas precision was estimated with Root Means Square (RMS). Such a study reported values lower than 0.4     \u2218     and 0.03     \u2218     of accuracy and precision, respectively. These results suggest that OSCANN can be considered as a powerful tool to measure oculomotor movement alterations involved in some neurological disease progression.<\/jats:p>","DOI":"10.3390\/s18020522","type":"journal-article","created":{"date-parts":[[2018,2,9]],"date-time":"2018-02-09T12:46:27Z","timestamp":1518180387000},"page":"522","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["OSCANN: Technical Characterization of a Novel Gaze Tracking Analyzer"],"prefix":"10.3390","volume":"18","author":[{"given":"Erik","family":"Hern\u00e1ndez","sequence":"first","affiliation":[{"name":"Aura Innovative Robotics, 28045 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santiago","family":"Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Aura Innovative Robotics, 28045 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Molina","sequence":"additional","affiliation":[{"name":"Aura Innovative Robotics, 28045 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Acebr\u00f3n","sequence":"additional","affiliation":[{"name":"Aura Innovative Robotics, 28045 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1067-0564","authenticated-orcid":false,"given":"Cecilia","family":"Garc\u00eda Cena","sequence":"additional","affiliation":[{"name":"Centre for Robotics and Automation, UPM-CSIC, Jos\u00e9 Guti\u00e9rrez Abascal Street, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1097\/WCO.0000000000000274","article-title":"Eye movements in neurodegenerative diseases","volume":"29","author":"MacAskill","year":"2016","journal-title":"Curr.
