Following stroke, a significant portion of individuals suffer from upper limb impairments and struggle with activities of daily living. Dedicated assistive technology (AT), such as robotic hand orthoses (RHO), can help facilitate upper limb usage and allow users to regain independence in their daily lives. Often, users' needs and requirements are neglected in AT design, thereby contributing to poor technology acceptance. In this work, we propose and apply a mixed-method focus group combining qualitative and quantitative components to gather user expectations in view of a user-centred redesign of a RHO. Three main themes emerged from a thematic analysis of two focus groups (n=5): Experience after stroke, desired design features, and reflections and realisations. Participants listed device features they would look for in AT and ranked them relative to what they deem important and necessary for a satisfactory device. Participants primarily looked for AT that is effective, intuitive and easy to use. These insights complement traditional technical design requirements for RHO by considering user desires, aspects unfortunately often neglected in the early design process. This work provides guidelines allowing for the optimization of AT design to better match the needs of persons after stroke and improve technology acceptance.
