Overview of assistive technologies for the blind: Navigation and shopping

One of the major driving forces behind technology development is the establishment of equality among everyone. It is intended that the strategic use of technology complements competencies or diminished capacities, improving self confidence and autonomy. Blind and partially sighted people often deal with this inequality in the performance of tasks or daily activities. The presented work reviews some of the proposed technologies to assist visually impaired people in common activities, specifically navigation and going shopping.
