These studies have increased in number and sophistication, also due to the availability of software tools for PDA to support the observers. A key methodological issue for these studies is the assessment of Inter-Observer Reliability (IOR). IOR is crucial for ensuring reliability of data collection in which multiple observers are involved. In workflow time studies the multivariate, time-stamped and ordered nature of the data limits the applicability of traditional inter-rater reliability measures, and makes this assessment challenging. Measures such as Cohen's Kappa, in fact, are only applicable to one variable at the time, so that high K scores for one aspect can be achieved even if two observers disagree substantially on other variables which are the object of their observation. Secondly, computing these measures first requires either matching pairs of datapoints from different observers viewing the same entity, a problem that cannot be done with perfect certainty, or restructuring the data into fixed-length time window sequences. No single method can address all the different aspects on which observers in time and motion studies can disagree, so one should adopt a composite method. We developed a set of functions and a Shiny app to assist this process for data collected with the Work Observation Method By Activity Timing (WOMBAT) method. The app allows the loading of data from pairs/groups of observers and computes a wide set of agreement measures on both matched data and on time window data. These measures are presented in a dashboard along with interactive visualizations of the observers’ data, and can be saved and plotted over time in a different section.","PeriodicalId":334884,"journal":{"name":"Proceedings of the 32nd European Conference on Cognitive Ergonomics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115831760","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}

Over the past two decades, several digital tools have been tried and tested to augment or even replace the physical affinity diagramming process. Even so, the analog process usually prevails. We developed an online collaboration tool specifically tailored toward affinity diagramming to explore the challenges and opportunities of such a system in the particular case where the distributed teams do not have access to co-located settings. Here, we present a user experience study of five groups (dyads) of students based on a one-hour diagramming task under remote observation, followed by semi-structured interviews. Our study contributes three distinct insights to inform future work, namely that digital affinity diagrams 1) reduce the awareness of co-participants’ actions, 2) provide fewer cues about ownership and use than physical diagrams, and 3) save time, improve manipulation, and overview. We end with a discussion of the challenges and opportunities for the design of digital tools for distributed teams involved in sense-making tasks.","PeriodicalId":334884,"journal":{"name":"Proceedings of the 32nd European Conference on Cognitive Ergonomics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115674402","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}

However, automated systems are expected to rely on human control and cooperation for a consequent amount of time. Thus, it is essential to (1) design carefully the interaction between the automated system and the driver and, (2) ensure proper trust and acceptance of the system. One way to do that is by providing drivers with longer time margins to prepare to intervene in driving in response to a takeover request. Extended sensing and prediction enabled by vehicle-to-infrastructure (V2I) connectivity might help to reach this goal. The experiment presented here aimed at investigating potential benefits of V2I on the interaction between the driver and the automated vehicle. In this study, carried out on a driving simulator, participants experienced two driving scenarios; one with an automated vehicle connected by V2I and one with a basic non-connected automated vehicle. Each scenario encompassed a takeover request caused by a roadwork zone. The vehicle connected with V2I allowed an anticipated takeover request. Those scenarios aimed at comparing (1) the safety of the driver intervention (2) driver's experience and mental workload during manual takeover and, (3) subjective evaluation of the system, with the connected and the basic automated vehicle. Results revealed a positive effect of V2I on the quality of driver's safety intervention in response to a takeover request and on the drivers’ subjective evaluation of the system and experience during the manual intervention.","PeriodicalId":334884,"journal":{"name":"Proceedings of the 32nd European Conference on Cognitive Ergonomics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126423232","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}
