Designing for the sense of touch is essential in creating convincing and realistic experiences in Virtual Reality (VR). Currently, a variety of methods exist for simulating touch experiences. However, developing effective and convincing haptic feedback still remains challenging. In this work, we study how real-world touch experiences can inform haptic design processes for VR. Firstly, we investigate the reproduction of haptic features by capturing and fabricating surface microgeometry. We show that haptic reproduction is able to create a wide range of feel aesthetics. Furthermore, we build upon procedural design by generating and fabricating haptically-varying surface structures. We show that digital design processes are able to generate flexible and universal structures that directly influence tactile dimensions, such as roughness and hardness. Lastly, we investigate correspondences between different sensory modalities to enhance the design of tactile experiences. We show that vocal expressions can translate a designer’s intent into effective haptic feedback, while providing a rapid in-situ design process. This thesis advances the fields of VR, haptic design, and fabrication by contributing knowledge to the question of how effective tactile experiences can be designed.
