Many hapticians have designed and implemented haptic effects to various user interactions. For several decades, hapticians have proved that the haptic feedback can improve multiple facets of user experience including task performance, analyzing and utilizing user perception, and substituting other sensory modalities. Among them, this talk introduces two representative rendering methods to provide vibrotactile effects to users: 2D phantom sensation that makes a user perceive illusive tactile perception by using multiple real vibrotactile actuators and vibrotactile dimensional reduction that reduces 3D acceleration data from real interactions to 1D vibrations for maximizing its realism and similarity.
Biography: Gunhyuk Park, Ph.D, is an assistant professor at the School of Electrical Engineering and Computer Science at Gwangju Institute of Science and Technology (GIST) in Korea from 2019. He received the BS and Ph.D in Computer Science and Engineering from Pohang University of Science and Technology in 2007 and 2017, respectively. He worked as a postdoctoral researcher in the Haptic Intelligence department at the Max Planck Institute for Intelligent Systems from 2017 to 2019. His main research area is haptics, which is a study about the sense of touch, and its applications with in-depth perception study for better user performance and experiences. His research has been applied to mobile devices, automobiles, motion-based remote controllers, surgical robots, and assistive interfaces for the hearing impaired.
