A Psychotechnological Review on Eye Tracking Systems: Towards User Experience

By Mele, Marie Laura; Federici, Stefano; Disability and Rehabilitation: Assistive Technology, Volume 7, Number 4, pages 261-281
Publication Date: 2012

Study undertook a critical review of the international literature to investigate the state of the art of eye tracking systems. Focus was on the psychotechnological aspects involved during the application of eye tracking methodologies in the assessment and rehabilitation process. Psychotechnologies are defined as technologies that can emulate, extend, amplify, or modify sensorimotor, psychological, or cognitive functions of the mind. The review was conducted through the main psychology, engineering, and computer sciences databases by following specific inclusion and exclusion criteria. A total of 46 matches from 1998 to 2010 were selected for content analysis. Four main thematic areas were identified and explored: (1) human-computer interaction: eye tracking methods and techniques, (2) cognitive processes involved in visual information processing, (3) use of eye tracking with children and adolescents, and (4) assistive technology use of eye tracking systems as input device. The study found that despite a growing attention to end users, most of the studies reviewed were far from being considered as adopting holistic human-computer interaction models that include both individual differences and needs of users. The user is often considered only as a measurement object of the functioning of the technological system and not as a real alter ego of the intrasystemic interaction. Based on review results, the authors recommend that a user centered approach be adopted for the development or improvement of new eye tracking devices and software in order to provide psychotechnologies working with, and not only for, these users.
