Drivers’ gaze behaviours are of particular interest as proper information processing by the driver is a key element to safe manual control resumption. In this study, 22 research articles were selected and reviewed to extract main gaze behaviours tendencies during takeover transitions. Despite a great variety in protocols and gaze metrics, categories of factors and gaze parameters have been established. The resulting data shows that at the onset of the takeover request gaze tend to be quickly reoriented towards the road ahead. Despite this, an increase in gaze dispersion on the road environment was found in automated driving. In addition, clear evidence for detrimental effects of visually engaging non-driving related activities on visual exploration strategies emerge (e.g., delay in reorienting the gaze towards the road ahead). Altogether, gaze data reveal the complexity of information processing during takeovers. A synthetical view of gaze parameters evolution during the takeover process has been established and associated with visual information gathering and processing. Finally, a broader view underlying the importance of combining technological approaches with human centred ones is proposed.

To assess the sensitivity, one parameter of the body part was changed while other parameters were left unchanged to understand its effect on the output score. Combinations of postures in which no change was observed and corresponding ranges were noted. Posture ratings with sudden jumps were also noted. Ordinal regression analysis was performed to identify the body variable with the greatest impact and its weight in estimating the OWAS action category.

The article proposes a broad methodological approach to examine such effects. A particular focus is placed on performance after-effects (e.g. unscheduled probe tasks), extra-role behaviour, and task management behaviour because of conventional performance measures (i.e. scheduled tasks) often being unimpaired by social stressors. The role of the ‘performance protection mode’ as an important concept is discussed. A distinction is made between three facets of after-effects: performance-related, behavioural, and emotional. Unscheduled probe tasks and voluntary tasks are proposed to measure performance-related and behavioural after-effects. Propositions for specific experimental scenarios are made, allowing for sufficiently realistic simulations of social stress at work. The availability of such lab-based simulations of work environments offers good opportunities for this line of experimental research, which is expected to gain in importance since highly automated systems may modify the impact of human-induced social stress or may even represent a social stressor themselves. Finally, the considerations presented in this article are not only of relevance to the domain of social stress but to experimental stress research in general.","PeriodicalId":22852,"journal":{"name":"Theoretical Issues in Ergonomics Science","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42224879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article proposes a Video Image-based Posture Assessment (VIPA) method as a highly capable one for assessing an activity requiring dynamic postures of workers. This article explains the various steps of VIPA and its application for (i) the extraction and classification of postures into different categories based on the instructed posture classes from 10 videos of soil loosening activity having 48,715 postures and (ii) the use of OWAS to evaluate the postures. VIPA relies on traditional posture evaluation methods. The results indicate that VIPA could identify precarious postures 30% of the activity duration; these results were found to be accurate and reliable because there is no sampling method involved. The capability of VIPA method is proven through the activity studied.","PeriodicalId":22852,"journal":{"name":"Theoretical Issues in Ergonomics Science","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45895419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was aimed to use Shannon’s entropy – PROMEHTEE hybrid model for weighing and prioritizing noise control solutions in an oil refinery. At first, the sound pressure levels were measured based on the recommended standard of ISO 9612. Next, criteria and noise control strategies were determined using the Delphi technique. In the third stage, the weights of the criteria were computed using Shannon’s entropy method and in the last stage, the solutions were prioritized by the PROMEHTEE method. Based on the results of Shannon’s entropy method, criteria in the order of priority included executive cost (0.2710), noise reduction efficiency (0.2531), feasibility (0.2435), safety (0.1120), possible interference with other processes (0.1107) and up-to-datedness of the methods (0.091). Also, based on the results of the PROMEHTEE method, the best solutions were construction of acoustic enclosures for people exposed to noise with a weight of 0.5476, and Modification or change of the work process with a weight of −0.6905, respectively.

Many quantitative studies have addressed the effects of music on drivers, but there has been a conspicuous dearth of qualitative research to provide a more nuanced understanding of music-related phenomena. Data collection took place over three simulated driving studies, each with different tasks/participants (Study 1 – n = 34, Study 2 – n = 46, and Study 3 – n = 27). The inductive content analysis was conducted by two members of the research team and a peer debriefing was conducted by a third. Findings show that music can have a range of affective, behavioural and cognitive effects (both positive and negative), that are moderated by the driving environment (i.e. urban vs. highway) and aspects of the musical stimulus (i.e. inclusion/non-inclusion of lyrics, loudness and tempo). Participants were mindful of the implications of in-vehicle music vis-à-vis the safety–performance–pleasure trade-off. The analysis suggested a perceived beneficial effect of music and consequent contribution to driving style/safety-related performance. Younger drivers’ apparent reliance on music as a means by which to regulate their emotion highlights an education need in terms of optimising selections.

NASA-TLX assesses mental workload across six load dimensions. When the dimensions are not assumed to be approximately equally important, they are weighted by conducting a pairwise comparison for every dimension pair, followed by the normalisation of weights reflecting the importance of the dimensions. This original NASA-TLX weighting method creates some challenges that are difficult to identify when the weights are being assigned. First, the original NASA-TLX weighting does not allow directly expressing two or more dimensions as equally important. Second, if pairwise comparisons are conducted consistently, there exists only one possible importance order for the dimensions. Third, with consistently conducted pairwise comparisons, a weight of 0.33 is artificially forced on the most important dimension. Swing and Analytic Hierarchy Process weighting methods for eliciting the weights of the dimensions are proposed as a solution to these challenges. The advantages of applying these methods in NASA-TLX are introduced theoretically and demonstrated empirically using data from virtual air combat simulations. The objective of this paper is to help scholars and practitioners to use NASA-TLX in mental workload assessments such that the discussed weighting issues are avoided.","PeriodicalId":22852,"journal":{"name":"Theoretical Issues in Ergonomics Science","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45243188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
