Outline of Final Research Achievements

In this study, we realized a visuo-haptic augmented reality (AR) system which delivers pinching and pulling interactions with AR objects. The system employs a cross-modal effect at the point where fingers feel an equivalent contacting sensation when pinching an object. It controls bathyesthesia sensation with visuo-haptic interaction based on a rendering algorithm that evokes haptic sensations without using haptic devices.Through a psychophysical experiments, we confirmed that this method enabled us to present as if they were touching a virtual object as same size as they were watching when the diameter of the virtual object is 25 mm or less.
