This course teaches how to use data for increased realism in haptic modeling and devices. The learning outcomes include understanding haptography, haptic recording devices, texture recording procedures, sound modeling, synthesizing sound outputs, and preference-driven tuning. Students will learn about haptic models, friction, texture generative models, and data-driven social touch. The teaching method involves a combination of theoretical concepts and practical demonstrations. The course is intended for individuals interested in haptic technology, data-driven modeling, and enhancing realism in virtual environments.
