Assistive systems for subjects with low vision

Abstract

Low vision is an acute form of impaired visual function due to multiple causes and changes in the patient's functional behavior. At the moment there is on the market of assistive technology products a wide range of such systems that can support patients with different degrees of visual impairment and at the same time can adapt to different activity requirements of these patients. However, the need has been identified to use more efficient and reliable devices in terms of manoeuvrability and to offer "freedom" of movement to patients using such systems. This paper presents some aspects related to the implementation of assistive technologies in the prevention and rehabilitation procedures carried out by the optometrist, in order to improve the activity of patients with multiple sensory and / or locomotor disabilities. The first part of the paper analyzes the prevalence of multiple sensory and motor disabilities in order to identify and develop dedicated and personalized assistive technologies in order to support these patients. In the second part of the paper are proposed two such variants of care systems that offer patients with low vision and blindness the opportunity to move safely to and from the points of interest of its activity. The final part of the paper presents the results and conclusions of the use of these assistive systems and the identification of their future improvement points so that patients become more and more secure in mobility, communication and information transmission / reception.
