Can't Touch this? Why Vibrotactile Feedback Matters in Educational VR
Fabian Froehlich, Jan L. Plass · 2024
This study investigates the relationship between vibrotactile feedback and sense of presence in VR. The inquiry focuses on corrective and reenforcing feedback in STEM learning outcomes using a VR environment called Looking Inside Cells. In a randomized within-subject design experiment (N=68) participants got assigned to a vibrotactile and non-vibrotactile condition. Our hypotheses: Participants in the vibrotactile-condition report higher sense of presence ratings compared to the non-haptic condition. Results indicate that vibrotactile feedback increases the sense of presence and impacts metacognition. Participants who received corrective feedback as a vibrotactile stimuli are more likely to underestimate their actual test performance.
