Using auditory menus on a mobile device has been studied in depth with standard flicking, as well as wheeling and tapping interactions. Here, we introduce and evaluate a new type of interaction with auditory menus, intended to speed up movement through a list. This multimodal “sliding index” was compared to use of the standard flicking interaction on a phone, while the user was also engaged in a driving task. The sliding index was found to require less mental workload than flicking. What’s more, the way participants used the sliding index technique modulated their preferences, including their reactions to the presence of audio cues. Follow-on work should study how sliding index use evolves with practice.

Virtual reality (VR) is commonplace for training, yet simulated physical activities in VR do not require trainees to engage and contract the muscle groups normally engaged in physical lifting. This paper presents a muscle activity-driven interface to elicit the sensation of forceful, physical exertions when lifting virtual objects. Users contracted and attained predefined muscle activity levels that were calibrated to user-specific muscle activity when lifting the physical counterpart. The overarching goal is to engage the appropriate muscles, and thereby encourage and elicit behaviors normally seen in the physical environment. Activities of 12 key muscles were monitored using electromyography (EMG) sensors while they performed a three-part patient lifting task in a Cave Automatic Virtual Environment. Participants reported higher task mental loads and less physical loads for the virtual lift than the physical lift. Findings suggest the potential to elicit sensation of forceful exertion via EMG feedback but needed fine-tuning to offset perceived workload.

AbstractObjectivesIn 2018, the ACGME (Accreditation Council for Graduate Medical Education) made a change to the maximum permissible number of consecutive nights a resident trainee can be on “night float,” from six to seven nights. To our knowledge, although investigators have studied overall discrepancy rates and discrepancy rates as a function of shift length or perceived workload of a particular shift, no study has been performed to evaluate resident-faculty discrepancy rates as a quality/performance proxy, to see whether resident performance declines as a function of the number of consecutive nights. Our hypothesis is that we would observe a progressive increase in significant overnight resident – attending discrepancies over the 7 days’ time.MethodsA total of 8,488 reports were extracted between 4/26/2019 to 8/22/2019 retrospectively. Data was obtained from the voice dictation system report server. Exported query was saved as a .csv file format and analyzed using Python packages. A “discrepancy checker” was created to search all finalized reports for the departmental standard heading of “Final Attending Report,” used to specify any significant changes from the preliminary interpretation.ResultsModel estimates varied on different days however there were no trends or patterns to indicate a deterioration in resident performance throughout the week. There were comparable probabilities throughout the week, with 2.17% on Monday, 2.35% on Thursday and 2.05% on Friday.ConclusionsOur results reveal no convincing trend in terms of overnight report discrepancies between the preliminary report generated by the night float resident and the final report issued by a faculty the following morning. These results are in support of the ACGME’s recent change in the permissible number of consecutive nights on night float. We did not prove our hypothesis that resident performance on-call in the domain of report accuracy would diminish over seven consecutive nights while on the night float rotation. Our results found that performance remained fairly uniform over the course of the week.
