Spatial understanding and cognitive mapping are challenging tasks for people with visual impairments. The goal of this work is to leverage computer vision and spatial understanding techniques along with audio-haptic proprioceptive interaction paradigms for assisting people with visual impairments in spatial comprehension and memorization. Abstract space exploration in the field of assistive didactics is tackled through tactile exploration and audio feedback resulting in two solutions. The first one focuses on math learning in primary education while the second one focuses on function graph tactile exploration and sonification. In the field of spatial comprehension during way-finding for people with visual impairments, computer vision and spatial reasoning techniques are used for detecting visual cues such as zebra pedestrian crossings and for safely guiding the user with respect to the detected elements. Suitable interaction paradigms based on sonification and haptic feedback are designed to assist the user efficiently and quickly during the navigation.
