A novel instrument, the Hand Vibration Threshold Mapper, was used in this study. 13 participants took part on this experiment. Significant differences were found between VPT scores obtained using the two methods. No significant differences were found between VPT scores obtained on the five fingers, when grouped by method. Significant differences were found between VPT scores obtained on the 3 frequencies, grouped by method. Design guideline recommendations aimed at haptic feedback developers were elaborated based on these results.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134373494","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}

{"title":"Didactic Strategy with Mobile Devices: An Approach for the correct use of English Verb Tenses","authors":"Evelyn Moore, Juan Murillo-Morera, Janio Jadán-Guerrero","doi":"10.54941/ahfe1002177","DOIUrl":"https://doi.org/10.54941/ahfe1002177","url":null,"abstract":"In the teaching-learning process, didactic strategies have become a valuable methodological tool, which allows learning a difficult subject in a structured way. In English, the correct conjugation of verb tenses: simple and progressive in the elementary level, requires a structured and innovative methodology to motivate their learning. The main problem of this research consists of the increasing difficulty of the fifth-grade students from an institution located in the district 04 of Costa Rica, in correctly assimilating the conjugation of the simple and progressive verb tenses of the English language. For its solution, the design, implementation and validation of a didactic strategy was proposed as a way to support the teaching-learning process of the correct conjugation of the simple and progressive verb tenses, through the use of mobile devices. The methodology followed presented a mixed study (qualitative-quantitative) through the application of surveys, expert judgment and a case of execution, as sources to collect and validate the proposed didactic strategy, within the context of philosophy and methodology of action research. The results obtained from both, teachers and students, have been representative. The teachers have identified a great interest of the students in learning the subject, making use of the proposed strategy, causing this, motivation and openness. In fact, the students who used the strategy as a supportive tool for their evaluations, obtained better academic performance on average: 5C (74.28%) compared to those who did not use it as a supportive tool: 5A (44.76%) and 5B (64%).","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130079243","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}

Few years after this event, in the coast of the Mediterranean Sea, on January 13th, 2012, a cruise vessel named Costa Concordia struck a rock formation on the sea floor, listing and capsizing the vessel, leaving 32 fatalities and dozens of wounded. Two accidents apart in time and space, in different domains - aviation and maritime - but which have more similarities than differences. In this study, a systematic analysis of these two accidents with the FRAM (Functional Resonance Analysis Method) is presented, based on the two official reports issued by the responsible authorities, as well as relevant scientific publications about these events. Applying a Human Factors approach, where work systems are analysed from worker’s perspective, understanding the interactions between organizational, technological, environmental, and individual elements, it was possible to comprehend and identify how the organizational decisions, taken in the executive offices, and company’s culture, resonate till the cockpit/bridge decisions. Particularly in these events, it was perceived that this resonance contributed to the accidents, evidencing the real complexity of the workplaces in the aeronautical and maritime industries, where actions, decisions and relationships reverberate (complexly) throughout the system. In this aspect, it was also noted that the levels of complexity of these two distinct domains, despite being structurally different, require the same adaptive and regenerative responses from work systems and, consequently, from workers, generating the organizational culture of work environments.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130035126","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}

Due to confinement, children and adolescents carry out many activities on the computer or mobile devices, including socialization, learning, entertainment. This activity, in some cases, has also led to negative behaviors, including cyberbullying among them, this being one of the main problems that affects their physical and mental health, generating episodes of anxiety and suffering. In this context, the article presents a methodology for the implementation and deployment of learning capsules with the purpose of preventing bullying and cyberbullying of children and adolescents. The study began with a systematic review of literature on Microlearning as well as existing practices and technologies on the market. The systematic review protocol considered the choice of four digital libraries for the search. The search method and selection of technological solutions was based on finding Apps and websites for parental control and early detection of cyberbullying. An evaluation of 16 technological solutions was carried out and some strategies were identified that will be useful to develop the learning capsules.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133930994","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}

These disorders are manifested gradually and, over time, symptoms become more persistent. The workers of the healthcare sector are one occupational group facing the severe consequences of WRMSD. Ergonomic risk assessments play a crucial role in monitoring and preventing the occurrence of such disorders. Recent technological advances have enabled direct and reliable exposure measurements with wearable devices. Ergo4workers (E4W) is a system consisting of wearable sensors and a smartphone app whose purpose is to aggregate relevant data from such sensors. It aims to provide an ergonomic assessment of work activities, namely regarding the posture adopted; in the current research applied to healthcare professionals’ work. E4W was developed adopting a User-Centered Design (UCD) approach, in which after an initial phase devoted to the understanding and specifying the context of use, the three following phases are carried out iteratively: specifying user and design requirements; solution design and implementation; and evaluation. This paper describes the usability evaluation of E4W app’s first prototype. Usability tests were performed in a laboratory environment involving seven participants. The Cognitive Walkthrough method was applied, and the participants performed tasks in three different scenarios. Data regarding performance metrics of task success, the time required to perform each task, the number of errors, and actions performed were collected for each scenario. At the end of the test, participants were asked to comment on their interaction with the interface. The performance metrics obtained for each usability test were closely analysed. These results were consistent with the verbal feedback obtained, and improvement opportunities for the prototype were identified. These modifications will be implemented in a second prototype. Overall, the prototype was positively evaluated, as participants mentioned its intuitive functionalities and appealing features, as well as the app’s usefulness.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123526392","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}

Indeed, 12% of all aviation accidents were due to human factors/ergonomics (HFE) issues during maintenance activity (Hobbs, 2000). However, regarding the aviation history, Human performance has been studied from the very beginning in the aviation field, especially regarding fixed wing accidents (Maurino et al., 1993; Wiener & Nagel, 1988). Initially, the reliability of machines was the primary concern, and many attempts were made to improve the technology of the devices (Maurino et al., 1993; Wiener & Nagel, 1988). During the following decades, HFE raised as a discipline to design the flight deck and to investigate the interaction between human (pilot) and machine, particularly, during the training phase of the pilot in a simulator (Wiener & Nagel, 1988; Horeman et al., 2015). Safety and comfort in the cockpit and the passenger cabin were also improved by considering HFE principles during the subsequent decades (Spenser, 2008). The consideration of Human Factors in maintenance is more recent. Integrating HFE in maintainability increases the quality of maintenance activities and reduces the rate of mistakes/errors (Gruber et al., 2015). The design engineers in the maintainability department interact and collaborate with other engineering departments (e.g., aerodynamic, hydraulic and electric integration, and architecture) and support disciplines including aircraft maintenance manual to consider maintenance & HF criteria during design phases. This interaction could raise HFE culture between them could effectively affect the future maintenance activity. However, aviation accidents are not the only problem that demonstrates the need to improve HFE for maintenance activities. The health and safety of maintenance operators is also a key contributor to maintenance errors (Hobbs, 2000). Various studies have already highlighted the fact that maintenance activities can cause health problems (musculoskeletal disorders, stress, and high mental workload) and workplace accidents (AFIM, 2004; European Agency for Safety and Health at Work, 2010). In a survey of 2,500 maintenance operators from various industries (automotive, train, and aeronautics), AFIM showed that 62% of respondents considered their occupation to be dangerous. Another study performed in Europe showed that 15%–20% of accidents at work occurred in the field of maintenance, suggesting that maintenance tasks are the most dangerous activities in an industry (European Agency for Safety and Health at Work, 2010).In order to reduce the risk of error, and also improve the work condition of maintenance operator, one of the solution is to better understand the current feedback of customer’s daily activity.

In this frame, the most sensitive maintenance tasks on existing helicopters have been studied to impact the design, procedure, mainten","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"111 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132330420","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}

New devices, which communicate with other devices via digital protocols, have emerged. Digital creations, including programs, applications, websites, and bots have also become widespread. These can be considered tools, but are simultaneously immaterial. As a raft of Internet of Things (IoT) products enter the market, a new stage of development can be seen on the horizon: IoT will be superseded by the Internet of Everything, which enables communication between material objects and data, programs, processes, and people. In this new world, technology will become active in new ways and gain new types of agency. Newly created technologies enter into a specific type of relationship with their users and exercise significant impacts upon them.This article presents the results of a qualitative study (28 individual in-depth interviews) conducted on users of different types of digital device, including wearable technologies, smart-home devices, digital applications, and voice assistants. It shows by example the various psychological and social consequences that users of these technologies experience and how those users view the technologies. IoT products can be treated as tools that empower their users. The notion of technology as an extension of the human body and mind was introduced by Marshall McLuhan and developed further by Andy Clark. They highlighted that technological solutions have assisted humanity by “moving” cognitive processes and agency beyond humans themselves. Clark offers examples of such derivation: paper, arithmetic, and writing are external extensions of the human mind. The emergence of the IoT trend introduces a new dynamic to this process: digital devices that have the ability to complement and extend human capabilities. This article proposes that these enhancements be categorised into two distinct groups: extensions (the strengthening of existing properties) and augmentations (the equipping of properties that humans did not previously possess). Through technology, users have access to the equivalent of new senses, such as instant remote knowledge of who is inside their homes, which doors are locked, and the exact location of the bus they intend to catch. These might also incorporate new skills—such as the ability to solve mathematical equations with a single click, or to cook a previously unknown dish—or character traits, such as perseverance or self-motivation. This article also intends to demonstrate that such dependencies can be two-sided. As well as the natural senses, users feel the need to employ technologically generated ones—for example, some users feel the need to “check” the condition of their empty homes, the status of their household appliances, or how much electricity their solar panels have produced. The wide selection of extensions and augmentations that cause users to function in a relational space of human and nonhuman actors have enabled new tech","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121886336","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}
