To create highly immersive experiences in virtual reality (VR) it isimportant to not only include the visual sense but also to involve multimodal sensoryinput. To achieve optimal results, the temporal and spatial synchronization of thesemultimodal inputs is critical. It is therefore necessary to find methods to objectivelyevaluate the synchronization of VR experiences with a continuous tracking of theuser. In this study a passive touch experience was incorporated in a visual–tactileVR setup using VR glasses and tactile sensations in mid–air. Inconsistencies ofmultimodal perception were intentionally integrated into a discrimination task. Theparticipants’ electroencephalogram (EEG) was recorded to obtain neural correlates ofvisual-tactile mismatch situations. The results showed significant differences in theevent-related potentials (ERP) between match and mismatch situations. A biphasicERP configuration consisting of a positivity at 120 ms and a later negativity at 370 mswas observed following a visual–tactile mismatch. This late negativity could be relatedto the N400 that is associated with semantic incongruency. These results provide apromising approach towards the objective evaluation of visual–tactile synchronizationin virtual experiences.
