“…Previously, sensorimotor synchronisation research with visual stimuli has focussed on simple cues such as flashing lights or bouncing spheres, which, while having significant effects on certain aspects of gait such as step timing and stride length [30], have limited scope for altering motion, given the amount of information they can convey. Existing research suggests spatio-temporal visual stimuli can result in improved synchronisation and coordination over temporal only stimuli as long as the spatial information is compatible [16] , [17] , [18]. In this study, participants failed to fully entrain to the spatio- Participants showed high deviation in terms of target tempo when attempting to match to fast cues, which resulted in the lack of synchrony.…”

MTE) ¶ These authors contributed equally to this work. & These authors also contributed equally to this work.The effectiveness of simple sensory cues for retraining gait have been demonstrated, yet the feasibility of humanoid avatars for entrainment have yet to be investigated. Here, we describe the development of a novel method of visually cued training, in the form of a virtual partner, and investigate its ability to provide movement guidance in the form of stepping.Real stepping movements were mapped onto an avatar using motion capture data. The trajectory of one of the avatar step cycles was then accelerated or decelerated by 15% to create a perturbation.Healthy participants were motion captured while instructed to step in time to the avatar's movements, as viewed through a virtual reality headset.Step onset times were used to measure the timing errors (asynchronies) between them. Participants completed either a visual-only condition, or auditoryvisual with footstep sounds included.Participants' asynchronies exhibited slow drift in the Visual-Only condition, but became stable in the Auditory-Visual condition. Moreover, we observed a clear corrective response to the phase perturbation in both auditory-visual conditions. We conclude that an avatar's movements can be used to influence a person's own gait, but should include relevant auditory cues congruent with the movement to ensure a suitable accuracy is achieved.

“…As such, this allowed us to investigate the potential impact of visual motor coordination difficulties in everyday life of obese individuals. To do so, this study utilised a pendulum based paradigm as it has been extensively used in motor control research over the past 20 years to ensure reproducibility [37, 38]. This allowed us to compare performance output between studies assessing normal participants and participants with motor difficulties such as schizophrenia and autism [19, 20].…”

Objective. To investigate whether obesity alters the sensory motor integration process and movement outcome during a visual rhythmic coordination task. Methods. 88 participants (44 obese and 44 matched control) sat on a chair equipped with a wrist pendulum oscillating in the sagittal plane. The task was to swing the pendulum in synchrony with a moving visual stimulus displayed on a screen. Results. Obese participants demonstrated significantly (p < 0.01) higher values for continuous relative phase (CRP) indicating poorer level of coordination, increased movement variability (p < 0.05), and a larger amplitude (p < 0.05) than their healthy weight counterparts. Conclusion. These results highlight the existence of visual sensory integration deficiencies for obese participants. The obese group have greater difficulty in synchronizing their movement with a visual stimulus. Considering that visual motor coordination is an essential component of many activities of daily living, any impairment could significantly affect quality of life.

“…Hence, discrete auditory stimuli provide a more reliable, salient cue compared to a discrete rhythmic visual cue ( Repp and Penel, 2004 ). However, more recent studies found that synchronizing movement to continuous visual cues, i.e., those exhibiting temporal and spatial information, yielded strong SMS that was comparable to studies using auditory cues ( Hove et al, 2012 ; Varlet et al, 2012 ; Armstrong et al, 2013 ). Moreover, visual trajectories representing biologically compatible movements further facilitates rhythm perception ( Su, 2014a ) and movement synchronization ( Su, 2014c ).…”

“…Indeed, it makes sense to have discrete points of reference for synchronization. On the one hand it has been shown that synchronization to continuous temporal-spatial visual cues is much easier and results in enhanced synchrony performance ( Varlet et al, 2012 ; Armstrong et al, 2013 ; Armstrong and Issartel, 2014 ) compared to the task of timing movements to discrete visual cues ( Repp and Penel, 2004 ; Elliott et al, 2010 ; Wright and Elliott, 2014 ). However, while the dynamic spatial element of visual information is clearly important for anticipatory timing, it would be inefficient to continuously align and correct movements at arbitrary points in the cue trajectory, just because there is the sensory information available.…”

Early, but not late visual distractors affect movement synchronization to a temporal-spatial visual cue

The ease of synchronizing movements to a rhythmic cue is dependent on the modality of the cue presentation: timing accuracy is much higher when synchronizing with discrete auditory rhythms than an equivalent visual stimulus presented through flashes. However, timing accuracy is improved if the visual cue presents spatial as well as temporal information (e.g., a dot following an oscillatory trajectory). Similarly, when synchronizing with an auditory target metronome in the presence of a second visual distracting metronome, the distraction is stronger when the visual cue contains spatial-temporal information rather than temporal only. The present study investigates individuals’ ability to synchronize movements to a temporal-spatial visual cue in the presence of same-modality temporal-spatial distractors. Moreover, we investigated how increasing the number of distractor stimuli impacted on maintaining synchrony with the target cue. Participants made oscillatory vertical arm movements in time with a vertically oscillating white target dot centered on a large projection screen. The target dot was surrounded by 2, 8, or 14 distractor dots, which had an identical trajectory to the target but at a phase lead or lag of 0, 100, or 200 ms. We found participants’ timing performance was only affected in the phase-lead conditions and when there were large numbers of distractors present (8 and 14). This asymmetry suggests participants still rely on salient events in the stimulus trajectory to synchronize movements. Subsequently, distractions occurring in the window of attention surrounding those events have the maximum impact on timing performance.
