DobbyEar: Inducing Body Illusion of Ear Deformation with Haptic Retargeting
Abstract: We applied haptic retargeting to induce body illusions by redirecting users’ hand movements, altering their perception of the shape of body parts when touched. Our technique allows for the realization of more precise and complex deformations. We implemented the mapping of the ear’s contour, thereby creating illusions of different ear shapes, such as elf ears and dog ears. Our research conducted three user studies to explore the impact of haptic retargeting on body ownership of virtual avatars.
Abstract: Previous research has explored various methods to provide feedback for interface interactions, but most approaches require specialized haptic devices. We introduced haptic retargeting to enable users to control multiple virtual screens in VR using a simple flat pad, which serves as a single physical proxy to support seamless interaction across multiple virtual screens. We conducted user studies to explore the appropriate virtual screen size and positioning under our retargeting method and then compared various drag-and-drop methods for cross-screen interaction.
