ABSTRACT
The choice of the appropriate assistive technology is conditioned by the visual skills of the subject. Visual perception is a complex process in which various subprocesses participate and in which various anatomic structures are involved. It is therefore necessary that the assessment protocol used permits having a clear picture of all of the visual abilities and skills of the patient as well as his/her limits. A detailed analysis of the visual skills permits the assistive technology assessment (ATA) team to plan specific test settings to be used with the patient without having to make random attempts, which usually prove themselves not only to be useless, but also to be frustrating for the patient and the family.
