This study aims to investigate how visual impairment affects neurophysiological and biomechanical responses during real-world navigation and daily activities, with a focus on the rehabilitative feasibility and impact of assistive technologies. These technologies include applications and wearable devices designed to support various aspects of daily living for individuals with visual impairment. The VIS4ION platform (Visually Impaired Smart Service System for Spatial Intelligence \& On-board Navigation), a wearable system providing tactile and auditory feedback, is one component of this broader study. VIS4ION is designed to enhance environmental awareness and reduce cognitive load during mobility tasks for the visually impaired.
