Silicone-Based Haptic Interfaces: Enhancing Multimodal Interactions through Pneumatic Tactile Feedback

This paper explores the potential of pneumatic haptic interfaces in enhancing human-computer interaction. We present two projects: one augmenting movie experiences with emotion-synchronized haptic feedback, and another integrating pneumatic interfaces into steering wheels for improved driver takeover in autonomous vehicles. The movie experience project demonstrated enhanced emotional engagement, while the automotive application showed improved safety and user trust. These applications highlight the versatility of pneumatic haptic technology across entertainment and safety contexts. We discuss the advantages of the Baromorph technique and outline future research directions, including comparative studies with vibrotactile feedback and machine learning approaches. This work contributes to the development of more insightful and emotionally intelligent interactive systems.
