Abstract:The Cutaneous Rabbit Effect (CRE) is a haptic illusion, where it feels like taps going down the arm, even though there are only two points of haptic stimulus. This research aims to discover how an Augmented Reality (AR) visual can influence the CRE. A vibrotactile sleeve is used, with a pattern that consists of four bursts. The duration between these bursts are called Inter-Burst Intervals (IBI). To visualise the CRE, a model of a crow is used. The results show that the CRE can be influenced by adding an AR visual. A sequence with an IBI of 52ms seems to create the illusion of the CRE the best when there are only haptics. When visuals get added, the IBI of 98ms gets the most influenced. Findings suggest that the visuals can be slowed down with a maximum IBI of 100ms before the illusion fades. These findings can be affected by the difference in haptic and visual experience of people, human errors, limitations in documenting options or displacement of the sleeve. For future research, it is recommended to improve body tracking, explore the effect of a sliding haptic pattern and slow down the sequence more.
