This project studies experiencing longer waits along the lines of ”no activity” (progress bar), ”passive waiting” (reading) and ”active waiting” (doing something). For the latter, a novel method is introduced: users swipe an image and content underneath unveils, as if it were a scratch card. A between-subjects experiment (n=410) was conducted using a mobile website in 3 conditions to gauge the effects on estimated waiting time and enjoyment. The “no activity” and “active waiting” conditions were estimated faster than the “passive waiting” condition. The “passive” and “active” waiting condition were more enjoyable than the “no activity” condition. When combining waiting time estimation (short is preferable) and enjoyment (higher is preferable) the “active waiting” condition yielded better results.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

The pre-incision time-out in particular aims to facilitate shared mental models prior to incision. Objective, unbiased measures to confirm its effectiveness are lacking. We hypothesized that providers' mental workload would reveal team psychophysiological mirroring during a formal, well-executed pre-incision time-out. Heart rate variability was collected during cardiac surgery cases from the surgeon, anesthesiologist, and perfusionist. Data were analyzed for six cases from patient arrival until sternal closure. Annotation of surgical phases was completed according to previously developed standardized process models of aortic valve replacement and coronary artery bypass graft procedures, producing thirteen total surgical phases. Statistical analysis revealed significant main effects. Tukey HSD post hoc tests revealed significant differences across provider roles within various phases, including Anesthesia Induction, Heparinization, Initiation of Bypass, Aortic Clamp and Cardioplegia, Anastomoses or Aortotomy, Separation from Bypass, and Sternal Closure. Despite these observed differences between providers over various surgical phases, the Pre-incision Time-out phase revealed almost negligible differences across roles. This preliminary work supports the utility of the pre-incision safety checklist to focus the attention of surgical team members and promote shared team mental models, measured via psychophysiological mirroring, using an objective mental workload measure. Future studies should investigate the relationship between psychophysiological mirroring among surgical team members and the effectiveness of the pre-incision time-out checklist.</p>","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

However, such representations might introduce several possible challenges for the human visual perception system, for example in perceiving brightness levels. Sonification, adding sound to the visual representation, might be used to overcome these challenges. As sonification provides additional information, sonification could be useful in supporting interpretations of a visual perception. In the present study, usefulness in terms of accuracy of sonification was investigated with an interactive sonification test. In the experiment, participants were asked to identify the highest brightness level in a monochrome visual representation. The task was performed in four conditions, one with no sonification and three with different sonification settings. The results show that sonification is useful, as measured by higher task accuracy.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

This paper investigates the maximum current limit of an IPMSM considering a large transient current at a symmetrical 3 phase short circuit fault. Finite Element Analysis (FEA) is used for the computation of 3 phase short circuit peak current while varying operating conditions including; input current vector and rotating speed. This computed 3 phase short circuit current is converted into dq-frame and then applied to check the irreversible demagnetization possibility of the IPMSM. During this process, the worst current angle is also investigated for considering partial demagnetization of permanent magnet.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

Our previous research, based on performance measures, showed that lightweight fonts have negative effects on text legibility and cognitive load when performing word search tasks. However, objective data and subjective perceptions of legibility and aesthetic appeal of fonts do not always correspond. In this paper we present the results of a subjective evaluation study of four variations of the Helvetica Neue typeface (ultralight, light, normal and bold) presented with high vs. low contrast and positive vs. negative polarity. 63 subjects volunteered in a pairwise comparison survey aimed at evaluating the preferences of respondents with regard to perceived legibility and aesthetic pleasingness of sixteen combinations of font weight, contrast and polarity. The results suggest that users of different ages evaluate the legibility of ultralight font as being very low, but younger users may perceive ultralight fonts as more aesthetically appealing than do older users. Based on our study, we provide recommendations on the use of lightweight fonts in user interface design.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

However, design teams face the challenges of synthetizing large amounts of information, often in a limited time, and with minimal common ground. We investigate these challenges through in-the-wild observations of six design meetings in three different projects, with professional design teams that follow a user-centered design methodology. We found that all the observed design meetings had a similar structure consisting of particular phases, in which design activities were organized around artefacts. These artefacts were used as input to disseminate and gather feedback of previous design outcomes, or as output to collect and process a variety of perspectives. From these findings, we synthetize practical guidelines to optimize artefact-based interactions during design meetings.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...

This quote is just one example of many negative respondents' reactions gathered during a large-scale user experience (UX) study. Unfortunately, the survey was no joke, rather a well-constructed and validated standardized UX scale. This paper critically reflects on the use and relevance of standardized UX scales for the evaluation of UX in business contexts. We report on a real-world use case where the meCUE questionnaire has been used to assess employees' experience (N=263) with their organization's intranet. Strong users' reactions to the survey's items and statistical analyses both suggest that the scale is unsuitable for the evaluation of business-oriented systems. Drawing on the description of this inadequacy, we discuss the quality of academic UX tools, calling into question the relevance for practice of academic methods.","PeriodicalId":93284,"journal":{"name":"ECCE ... : proceedings of the ...
