EMA uses a modular system for describing human work activities based on a pre-defined library of “complex operations”, which allows the generation and simulation of human movements with highly-automated algorithms. Moreover, EMA includes standard tools for the assessment of ergonomic strains (EAWS – “Ergonomic Assessment Worksheet”) and production time (MTM – “Methods Time Measurement”). After introducing some basic analysis functions of EMA and their typical use cases, this paper presents an evaluation study that examines the validity of EMA ergonomic evaluations in comparison to paper-pencil-assessments with EAWS. Moreover, this paper shows several use cases of the EMA software application in automotive and aviation industry. These applications illustrate that EMA considerably reduces the effort for preparing human simulations and enables the user to analyze ergonomic conditions (body posture, action forces, manual load handling) and productivity (e.g., walk ways) very thoroughly.","PeriodicalId":259265,"journal":{"name":"AHFE International","volume":"437 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":"133555860","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}

Even though some in-car interaction already takes place with mid-air gestures, the utilization of this type of feedback is still uncommon. In this study we evaluated how environmental vibration affects the recognition of ultrasound haptic feedback exposed to the driver’s hand. Four skin stimulation shapes of two durations were projected onto the driver’s palm while driving a simulator within a laboratory setting and in a test vehicle on a closed track. Results show that road vibration had a very little effect on driver’s ability to recognize the shape of the stimulation, but, some shapes may require additional training to be recognized consistently. Our findings also suggest that ultrasound haptic output can remain an efficient feedback source even in noisy vibration environments, (i.e., on the road) as compared to conventional vibrotactile feedback, thus drivers can focus their attention more towards the primary task and yet still interact with the onboard IVIS.","PeriodicalId":259265,"journal":{"name":"AHFE International","volume":"7 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":"133695270","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}

Such critical software systems should provide highly secure services for establishing if user access should be granted or not. As it will be highlighted in this paper, there is an intrinsic conflict between creating user authentication services that are secure, yet easy to use by the end-users. Our main goal is to adopt a human-centric approach which consists to study the intimate relationship between usability and security before the user authentication service has been implemented and deployed. We propose a framework that models the usability and security symmetry meaning the security consequences of usability issues. It suggests a novel usable security protocol through an inspection method named Usable Security Symmetry for dealing with usable security of user authentication methods that in turns will guide the development of truly secure and usable user authentication systems. The framework uses NGOMSL (Natural Goals, Methods, and Selection Language) to understand the user cognitive processes involved in user authentication while helping to identify and model the diverse situations of conflict between usability and security attributes.","PeriodicalId":259265,"journal":{"name":"AHFE International","volume":"295 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":"133270629","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}

Semi-structured interviews with 12 semi-literate learners, the teacher and two native language speakers were conducted. The dataset was collected from a private service provider, and it includes a digital footprint of training. The training was a 20 weeks pilot experiment, and it was implemented in early 2020. The design was based on the user's previous experience. The perceived major crucial success factors are empathic and equal interaction, encouragement, ease, trust, security, multilingual and technological support, and competencies of the parts of training. The empathy-based, carefully planned interactive digital design may be effective, attractive and easy for semi-literate learners.

The outlet system is built with six vertical ducts located in the central area above the head level. The design was developed inside an experimental chamber with dimensions of 4.50×2.55×2.50 m3 and was built with an inlet and an outlet systems using ducts with 0.15 m diameter. The vertical ducts are made with consecutive nozzles in both sides of the horizontal main duct. The vertical, longitudinal and transversal airflow fields are evaluated.

The latest pose estimation technologies in computer vision could help provide real-time analysis on exercising motion using on-device cameras. However, to identify whether an individual is performing an exercise correctly, postural deviations or anomalies from the correct patterns must be identified. In this study, a versatile solution is formulated to detect and analyze a specific resistance training exercise – bicep curl using BlazePose and binary tree algorithms in machine learning based on specific pose features. Ten decision tree models are developed to identify ten target pose anomalies including deviated trunk angles and misplaced elbows and wrists. The model sensitivity ranges from 73.7% (external rotated shoulders) to 97.4% (over-flexed trunk). These predicted results would be very useful in giving specific postural advises to learners of fitness exercises. Our research outputs could be extended to other exercises, and be implemented in mobile applications for various purposes such as exergames and sports analysis.","PeriodicalId":259265,"journal":{"name":"AHFE International","volume":"15 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":"127461108","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}

The model outlines how compassion can be injected in the nature of the companion to fulfill its role within a compassionate game.
