Realistic simulation and perceived “immersion” within a multimodal display for telecommunication and entertainment can be enhanced, or completely mitigated, as a function of inter-modal timing asynchronies between the multimodal rendering systems (system-system asynchrony). Tolerable asynchronies are have been extensively examined for auditory-visual stimuli but less so for auditory-haptic cues. Realistic simulation and perceived “immersion” can be enhanced, or completely mitigated, as a function of inter-modal timing asynchronies between the multimodal rendering systems. Data are presented from two experiments where auditory stimuli are varied in time of arrival (lead-lag) relative to a tactile pulse. Results indicate variability between participants in terms of overall sensitivity. Generally, sensitivity is greater for auditory stimuli leading haptic stimuli, compared to the opposite condition.
