  • Fig. 1 Uncanny valley of haptics.

    (A) The theoretical uncanny valley of haptics as defined by studies from the classic humanoid robotic uncanny valley (1). (B) The empirical data from our experiments. The subjective experience corresponds to the Presence Questionnaire score. Error bars represent SEM. (C) A diagram showing the stimulation paradigm for producing the illusion of spatialized haptic feedback via funneling. In generic haptics stimulations, the same amplitude of vibrations was delivered for all trials to both controllers. No funneling occurs in such conditions. However, under the spatialized and visual + spatialized conditions, a funneling effect was achieved by varying the vibrotactile amplitude delivered at each controller, producing a change in the perceived haptic location. (D) Inside the VR headset, the participant sees a (virtual) wooden dowel that bridges their hands (as sensed by the position and orientation of the controllers). In the passive and causal experiments, the participant held the dowel in a specific “activation area” to receive the haptic stimuli (represented by a “cloud” that looked like a smoky cylinder). During the visual + spatialized stimulation, participants saw a white marble cue that visually reinforced the location of the haptic feedback.
