This paper presents findings on the unimodal and multimodal feedback design for the interaction with a virtual knob. Since the physical knob provides haptic feedback while being rotated, we also integrated haptic feedback in the virtual knob. The real and virtual knob consist of a main body and a handle on top. For fine and coarse adjustments, the knob can be grabbed and rotated with a ’Grasp’ or a ’Pinch’ gesture. In a user study with 30 participants, we evaluated our system using objective measures and subjective metrics. The results show that participants reported a preference for having a haptic feedback and perceived it as more natural.
