abstract

• The cognitive perception of scenes or objects of large or very small size, such as the architecture of a building or the anatomy of a cell, is based mainly on the visual appreciation of the scene or object through photographs, computer images, or the physical presence. However, in the case of visually impaired people, visual appreciation cannot be used, so the cognitive process is based on auditory and tactile appreciation. Nevertheless, tactile appreciation is practically impossible when dealing with very small or extremely large objects or scenes. In this work, the use of the tactile appreciation by computer, also known as digital touch or virtual touch, is proposed as an educational communication strategy for people with visual disabilities. Digital tactile appreciation is achieved with haptic systems, which add the sense of touch to the human-computer interaction, allowing the user to touch or feel virtual scenes or objects. The results obtained show that participants with visual disabilities can learn to identify objects using digital touch by computer. © 2022 Fundacion para la Investigacion Social Avanzada.
