Since 1996, Dr. Jaime Sánchez and a team of researchers develop a line of research, development, and practice on Computer-Based Audio and Cognition in Blind Children. We study the role sound and voice can have in shaping the cognition of blind children. We design diverse audio-based virtual environments, cognitive tasks, and usability methods to develop and practice cognitive processes such as tempo-spatial relationships, memory, problem solving, mobility, orientation, spatial abstraction, haptic perception and cognitive integration. We also explore the use of audio to assist blind learners to understand the basic of mathematics school curriculum. All of these is guided by the premise that computer-based audio may have a meaningful role in the cognitive development of the blind child.
