<p>How
does haptic feedback during human-virtual character interaction affect
participant physiological responses in virtual reality? In this
between-subjects study, haptic feedback and non-haptic feedback conditions in
which virtual characters bump into the participant who is immersed in a virtual
environment are compared. A questionnaire was developed to determine the influence
of haptic feedback on presence, embodiment, positive and negative affect, interaction
with virtual characters, and haptic feedback realism, among other more
exploratory concepts. These exploratory variables include engagement, flow,
comfort with virtual characters, comfort with virtual characters’ appearance,
realism of virtual character interaction, realism of haptic feedback, and
virtual reality sickness. Physiological data was collected using galvanic skin response
(GSR) to investigate the influence of haptic feedback on physiological arousal during
human-virtual character interaction. Five conditions were developed (no haptic
feedback, full and half intensity, incorrect position, and delayed timing).
Significant differences were found in embodiment, realism of virtual character
interaction, haptic feedback realism, and GSR amplitude after the first
interaction with the virtual character. These results may inform future virtual
reality studies that investigate haptic feedback during human-virtual character
interaction and/or arousal via GSR data, as well as advise studies that seek to
correlate self-report responses with physiological data. </p>
