Adjustable Graphical Notation and Accessible Hardware to Accommodate the Force Feedback Design Process: Redesign of Feelix based on Preliminary Evaluations of Design Tools and Methods.

Feelix is a haptic authoring tool developed to support the design of force feedback and motion in user interfaces. The design of the tool has been informed by guidelines derived from prior research on the haptic interaction design process and haptic authoring tools. This paper presents studies that have been conducted to evaluate the design method and tools presented in Feelix through workshops and longitudinal evaluations with researchers and students from two different universities. The insights from the preliminary evaluation are translated into implications for the design of tools and toolkits for the development of haptic user interfaces. To conclude, we describe how the insights from the study, and the subsequent derived implications, have informed the redesign of Feelix.
