This paper presents the creation of an assembly simulation environment with multisensory feedback (auditory and visual), and the evaluation of the effects of auditory and visual feedback on the task performance in the context of assembly simulation in a virtual environment (VE). This VE experimental system platform brings together complex technologies such as constraint-based assembly simulation, optical motion tracking technology, and real time 3D sound generation technology around a virtual reality workbench and a common software platform. A peg-in-a-hole and a Sener electronic box assembly task have been used as the task cases to conduct the human factor experiment, using sixteen participants. Both objective performance data (i.e., task completion time, TCT; and human performance error rate, HPER) and subjective opinions (i.e., questionnaires) on the utilization of auditory and visual feedback in a virtual assembly environment (VAE) have been gathered from the experiment. Results showed that the introduction of auditory and/or visual feedback into VAE did improve the assembly task performance. They also indicated that integrated feedback (auditory plus visual) offered better assembly task performance than either feedback used in isolation. Most participants preferred integrated feedback to either individual feedback (auditory or visual) or no feedback. The participants' comments demonstrated that nonrealistic or inappropriate feedback had a negative effect on the task performance, and easily made them frustrated.

Musicians anticipate the effects of their actions during performance. Online musical imagery, or the consciously accessible anticipation of desired effects, may enable expressive performance when auditory feedback is disrupted and help guide performance when it is present. This study tested the hypotheses that imagery 1) can occur concurrently with normal performance, 2) is strongest when auditory feedback is absent but motor feedback is present, and 3) improves with increasing musical expertise. Auditory and motor feedback conditions were manipulated as pianists performed melodies expressively from notation. Dynamic and articulation markings were introduced into the score during performance and pianists indicated verbally whether the markings matched their expressive intentions while continuing to play their own interpretation. Expression was similar under auditory-motor (i.e., normal feedback) and motor-only (i.e., no auditory feedback) performance conditions, and verbal task performance suggested that imagery was stronger when auditory feedback was absent. Verbal task performance also improved with increasing expertise, suggesting a strengthening of online imagery.

Purpose Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and without PD. Method Individuals with PD and neurologically healthy controls performed speech tasks (reading and extemporaneous speech tasks) and an oscillatory manual task (a counterclockwise circle-drawing task) in isolation (single-task condition) and concurrently (dual-task condition). Results Relative to speech task performance, no changes in speech acoustics were observed for either group when the low-demand motor task was performed with the concurrent reading tasks. Speakers with PD exhibited a significant decrease in pause duration between the single-task (speech only) and dual-task conditions for the extemporaneous speech task, whereas control participants did not exhibit changes in any speech production variable between the single- and dual-task conditions. Conclusions Overall, there were little to no changes in speech production when a low-demand oscillatory motor task was performed with concurrent reading. For the extemporaneous task, however, individuals with PD exhibited significant changes when the speech and manual tasks were performed concurrently, a pattern that was not observed for control speakers.
