Application of a user-centered design approach to the development of XoSoft – A lower body soft exoskeleton

The objective of this research was to apply a user-centered design approach to the development of a soft exoskeleton for lower limb assistance. There has been a clear shift from hard to soft robotic exoskeletons in recent years. Soft exoskeleton technologies typically comprise sensors and actuators embedded in fabric/technical textiles. This approach to physical assistance offers benefits in usability for wearers, but also presents challenges e.g. how the concepts are put on/off and worn for long durations considering the personal needs of the wearer. Presented is a structured three-cycle development approach which considers user-centered design principles, but also a participatory user-driven design-test-redesign methodology. Target users for the concept (older adults, individuals post-stroke or incomplete spinal cord injury) were involved in concurrent design evaluation and development throughout the design process.
