Abstract:
(text automatically translated from Italian) The Ocular Pointers “***eye tracking” allow to a person who concentrates the look on one screen “to choose”, with the single movement of the eyes, a key, one letter, one phrase: they are, becoming simpler, of the “ocular mice” that once it calibrates to you on the single person allow, to who is in a position to only shuttling the eyes, to communicate with the world. These assistive devices are therefore of greatest importance for all the persons hit from serious neurovegetative pathologies like the ALS (Amyothrophic lateral sclerosis), from traumatic syndromes ***post for high cervical lesions that involve a complete tetraparesis (***cioe' the ***impossibilita' of budging all the limbs) etc These persons, also maintaining to the cognitive abilities and the advanced cerebral functions unchanged, they endure a strict alteration of the expressive ability is report that written and forgiveness the faculty of communication and relation, risking to living in the total isolation. The movement of the eyes remains the only possible movement that he is but sufficient, thanks to these extraordinary instruments, for ***esplicare some essential needs of independence: to communicate, to work, to amuse themselves, to pass the free time and to control just the environment of life. ***Eye Tracking analyzes, through one digital television camera, the movement of the eye and in particular the position of the ***pupilla. Generally the eye comes “illuminated” from an emitter of infrared light that defines the contour of the ***pupilla and creates an luminous glare that comes captured ***dalla the television camera to highest resolution. These glares come then drawn up from a special software in order to calculate the position of the look respect to an object or one position on the display of the computer. Currently 8 products of Ocular Pointers of which 5 distributed on the Italian market (***Quick Glance exist, ***Erica, ***EyeGaze, ***My Tobii P10, ***TM3).
