Haptic interaction is a critical focus in natural human-computer interaction, with haptic interaction interfaces demonstrating significant potential for enhancing emotional communication between users or between users and computers. The work aims to develop a systematic, accessible, cost-effective, and experiential haptic interface prototyping tool, to address the challenges faced by designers in haptic interface development, such as the lack of foundational knowledge in haptic physiology and interaction principles, insufficient design process guidance, and limited technical development support, thereby enabling more effective user experiments and advanced design work. Firstly, the participatory design methods were employed to identify the primary challenges and core requirements of interaction designers in haptic interaction interface design. Secondly, based on this, the guidance for haptic interaction design processes and the essential elements for encoding emotional haptic signals were built. Moreover, hardware tools supporting the iterative development of emotionally-enhanced haptic interaction prototypes were developed and the systematic design of the prototyping tool was completed. Finally, the preliminary affective interaction effects of the pneumatic feedback interface were validated through scenario-based testing in user experiments, and a foundational affective-haptic mapping reference effect library was established. In this study, a haptic interface prototyping tool has been developed, which through a systematic design process and user-friendly operation, facilitates more flexible and convenient design research and practice for haptic interaction designers. The tool enhances the efficiency of haptic interface design and offers extensive possibilities for creating emotionally rich haptic interaction experiences.
