Reading Support: development of a prototype for aiding people with low vision – preliminary tests

Abstract

Low vision is an intermediate condition between normal vision and blindness, secondary to an irreversible impairment of the visual system, causing losses in performance and achievement of certain activities. To minimize these problems, it is recommended the use of Assistive Technology resources. The objective of this paper was to report the development of a Reading Support (RS) prototype and describe the results of the preliminary tests. For the methodological aspect, a survey of different assistive devices available for individuals with low vision was conducted and it was decided to build a Reading Support prototype that considers the ergonomic needs of the user, with low cost, easy access and within the concept of universal design. The results were: reading support comprised of a support base, a reclining top facilitating the portability and rails to drive the lens holder. It was concluded that the equipment developed has positive aspects such as better maintenance of posture, good usability, considerable portability and good ergonomic viability, but it will be essential to continue the equipment testing with the target population to ensure the actual usability and applicability of the device.
