User-centered design of an adaptively morphing human-machine interface

Abstract: Adaptively morphing (shape changing) human hand-machine interfaces aim at increasing usability for various users, especially older walking-aid users with impaired hands. This paper introduces such an interface design for a five-finger hand-handle contact consisting of machined and additive manufactured components. Functionality is achieved via a granulate-filled flexible shell and pneumatic-actuated jamming. The interface is tested in a realistic use context experiment. The results contain positive subjective comfort evaluation and a digital workflow for design parameter analysis. Further design iterations considering these parameters are proposed.
