Assessing the impact of multisensory attributes of Textile-based Assistive Devices (TADs) on the experiences of end-users

Researchers have defined and measured functional attributes of assistive devices, yet there are multiple dimensions of a device worn temporarily or for life that remain unexamined. The purpose of this study was to explore how the sensory attributes of assistive devices impact consumers in order to build a foundation for a holistic approach to product development. Two online surveys targeting wearers of textile-based assistive devices (TADs) (n=29) and caregivers (n=8) were used for data collection. Survey questions related to sensory experiences (visual, tactile, auditory, olfactory) and describe how device usage and purchasing was impacted. Results suggest that multisensory experiences of users and caregivers involve more complexity than functionality alone. Multisensory effects were diverse in both groups. Some expressed a desire for their device to be more visible and expressive, while others chose not to use, expressing fear of judgment based on visibility. Insight into multisensory aesthetics and how design can be used to conceal, reveal, or provide opportunities for self-expression, as well as avoid embarrassment for the wearer, will help designers understand how assistive devices can be improved and developed to meet the needs of individuals with disabilities. Findings suggest that existing measures of success should include questions about sensory attributes.
