Cross-Modal Transfer

Cross-modal transfer refers to the ability to recognize or process information received through one sensory modality (such as touch or hearing) based on experience gained through a different modality (such as vision). In accessibility and assistive technology, cross-modal transfer is the principle underlying sensory substitution devices that convert visual information into auditory or tactile signals for blind users. For example, a person can recognize the shape of a key whether they see it or feel it in their pocket. Understanding cross-modal transfer capabilities is essential for designing effective non-visual interfaces that convey spatial, environmental, or visual information through alternative senses.
