“…This conclusion is based on subtraction of the lag caused by the technical implementation from the mean RT of T condition and supported by earlier findings showing about 30-40 ms shorter RTs to tactile than visual stimuli (e.g., [3,5,21]). Following this, tactile instructions would seem to have the potential to enable even faster knee lift reactions than conventionally used visual instruction provided that the onset of the tactile stimulus could be reliably situated to the initial phase of the instructor's leg movement.…”

“…As compared to auditory RTs, tactile RTs have been found to be less affected by distractions such as a concurrent secondary task (e.g., [4]). This is probably because, in contrast to visual and auditory events, tactile events are in direct physical contact with the organism and thus evoke more readily the interest of an organism [5]. Mechanisms to react to tactile stimulation are among the first ones to develop as evidenced by the palmar grasp reflex 2 Advances in Human-Computer Interaction of fetuses [6].…”

The present aim was to investigate functionality of vibrotactile stimulation in mimicry-based behavioral regulation during physical exercise. Vibrotactile stimuli communicated instructions from an instructor to an exerciser to perform lower extremity movements. A wireless prototype was tested first in controlled laboratory conditions (Study 1) and was followed by a user study (Study 2) that was conducted in a group exercise situation for elderly participants with a new version of the system with improved construction and extended functionality. The results of Study 1 showed that vibrotactile instructions were successful in both supplementing and substituting visual knee lift instructions. Vibrotactile stimuli were accurately recognized, and exercise with the device received affirmative ratings. Interestingly, tactile stimulation appeared to stabilize acceleration magnitude of the knee lifts in comparison to visual instructions. In Study 2 it was found that user experience of the system was mainly positive by both the exercisers and their instructors. For example, exercise with vibrotactile instructions was experienced as more motivating than conventional exercise session. Together the results indicate that tactile instructions could increase possibilities for people having difficulties in following visual and auditory instructions to take part in mimicry-based group training. Both studies also revealed development areas that were primarily related to a slight delay in triggering the vibrotactile stimulation.

“…However, attention to tactile stimuli under the involuntary and voluntary movement conditions may become intense compared with the no movement condition. In this respect, Hanson et al [21] demonstrated that temporal tactile perception was fixed despite attentional load. Hence, it seems difficult to attribute our results to the effect of attention.…”

SUMMARYThe present study aims to investigate the effect of voluntary movements on human temporal perception in multisensory integration. We therefore performed temporal order judgment (TOJ) tasks in audio-tactile integration under three conditions: no movement, involuntary movement, and voluntary movement. It is known that the point of subjective simultaneity (PSS) under the no movement condition, that is, normal TOJ tasks, appears when a tactile stimulus is presented before an auditory stimulus. Our experiment showed that involuntary and voluntary movements shift the PSS to a value that reduces the interval between the presentations of auditory and tactile stimuli. Here, the shift of the PSS under the voluntary movement condition was greater than that under the involuntary movement condition. Remarkably, the PSS under the voluntary movement condition appears when an auditory stimulus slightly precedes a tactile stimulus. In addition, a just noticeable difference (JND) under the voluntary movement condition was smaller than those under the other two conditions. These results reveal that voluntary movements alternate the temporal integration of audio-tactile stimuli. In particular, our results suggest that voluntary movements reverse the temporal perception order of auditory and tactile stimuli and improve the temporal resolution of temporal perception. We discuss the functional mechanism of shifting the PSS under the no movement condition with voluntary movements in audio-tactile integration.

“…In our study, although we asked participants to pay attention to tactile stimulus to eliminate the effect of attention, it was seemed that the attention on tactile stimuli in Voluntary and Involuntary conditions might become strong compared to No-movement condition. However, Hanson et al, [16] demonstrated that temporal tactile perception was fixed despite any attentional load. Therefore it is difficult to account for the present results by the effect of attention.…”

We investigated the effect of voluntary movement on temporal multimodal integration using a psychological experiment. The present study used auditory-tactile Temporal Order Judgment (TOJ) task to measure the differences in Point of Subjective Simultaneity (PSS) and Just Noticeable Difference (JND). To distinguish the effect of voluntary movement and proprioceptive feedback, we prepared three conditions: Voluntary condition, Involuntary condition, and No-movement condition. Voluntary movement and Involuntary movement shifted PSS to the point where an auditory stimulus presented prior to a tactile stimulus compared to No-movement condition. Furthermore, the shift of PSS in Voluntary condition was larger than that in Involuntary condition. JND of Voluntary condition was smaller than those of the other two conditions. These results revealed that voluntary movement improved temporal resolution between auditory and tactile stimuli.Moreover, it was demonstrated that voluntary movement also alternates audio-tactile temporal integration.
