Abstract
This thesis aims to explore the feasibility of a proof-of-concept parametric software that empowers occupational therapists (OTs) in fabricating customized adaptations of assistive technologies (ATs) to effectively address the distinctive requirements of individuals with hand impairments. The platform enables OTs to modify pre-designed models of utensil grips, serving as examples of ATs, based on individuals' hand assessments and anthropometric data. We conducted observations and interviews to gain insights into the AT adaptation processes by OTs for individuals with hand impairments. Subsequently, using an iterative design process, we created an interface prototype that allows for customized adaptations of ATs and invited an OT to participate in the preliminary testing of the prototype. Furthermore, a usability test was carried out with OTs to achieve a comprehensive appraisal of the parametric design tool's practical application and to obtain insights to the physical ATs for the hand that were generated. Lastly, we provide an outline of the design requirements for parametric modeling tools that support OTs and other clinicians to design customized ATs for individuals with limited hand dexterity.
