Complex Information System (CIS) interactions include both informational and operational interaction behaviors, and Information interaction is regarded as a critical aspect in defining the quality and efficacy of system functionality. TIn order to assess Cognitive Friction (CF) and inform ensuing interface design improvement, this paper integrates numerous CL assessment aspects. First, a conceptual framework for the method is built by examining measuring metric differences and integrating them through literature research, which is then combined with the user research process in design. Second, using this framework as a reference, a comparative experiment on user CF measurement was carried out by fusing eye tracking with the cause and assessment factors of CL. Ultimately, the user was provided with the CF index under the multidimensional dimension using the Fuzzy Comprehensive Evaluation (FCE). The findings demonstrate that the Multidimensional User Cognitive Friction Measuring (MUCFM) approach may more accurately capture the degree of CF in the information interaction of CIS interfaces. The viability of the comparative integration method is confirmed by eye tracking tests.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"66 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":"133765409","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 aim of the research is to establish methodological strategies with virtual assistants, for elementary school students through innovative and interactive classes, to develop the macro skills of the English language. The methodological design of this study is based on a mixed qualitative-quantitative approach, with the participation of an expert on \"Virtual assistants in the English language\", five teachers from the English area and 57 elementary school students from a private school in Ecuador. The data collected from the teachers made it possible to identify the main problems that students have when it comes to developing macro skills in the English language. With the support of the education expert, a strategy was designed using virtual assistants. The personal assistant Alexa, with great programming flexibility, was selected, applying a strategy focused on four macro skills: listening, reading, speaking, and writing. Each activity was aimed to reinforcing each skill according to students’ level at school. For example, for speech skills, students had to engage in a dialogue with Alexa through a game of questions and answers. For listening skills, Alexa would tell a story to determine the level of comprehension. For reading skills, the students were given a reading from which they were asked questions that Alexa could answer and through this the students developed writing skills according to the questions they answered. After the intervention, a post test was applied and it was shown that there was an improvement in the development of skills. It was concluded that the interactive classes motivated the participation of all students. For future work, we intend to carry out a longitudinal study with the use of virtual assistants and a comparison between other devices.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"31 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":"132112272","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}

We are concerned here with monitoring a moving quay crane spreader so as to make sure that safe clearance distances are maintained from the locations of dock workers in a port container cargo handling environment. The paper describes the application of computer vision techniques to develop a model-based, monocular spreader tracker. By tracking in three dimensions the position and orientation of the spreader during loading and unloading operations, a threat volume enclosing it can be defined. Constantly monitoring the distance of dock workers from this threat volume can improve the operator’s situational awareness and increase safety in the work environment.

After a stroke, deficits in perceptual and cognitive functions may arise, with particular emphasis to impairments caused to visuomotor skills. In this way, its stimulation, within a therapeutic rehabilitation context, is truly relevant for the recovery of lost functions. RehabVisual, presented in earlier works, is a digital platform that allows for an objective and standardized assessment of visuomotor skills and specific clinical interventions for each patient. In the current work, new features are added to the platform, to make it more optimized and suitable for use in clinical practice, with adults who suffered a stroke. Herein the platform is also thoroughly validated with healthy subjects.Objective: This work’s goals are twofold: to assess the accuracy of the eye tracking system developed, which is integrated in the platform; and to test and validate the digital platform itself, with a population of healthy subjects.Methodology: 50 healthy subjects tested the RehabVisual digital platform in a laboratory context. In addition to testing the overall visuomotor rehabilitation functions, dynamic stimuli following was collected from both the platform’s own camera and a Tobii Pro Nano Eye Tracker, which is considered as gold standard to assess direction of gaze. The results of both systems were compared.Results: The platform’s own eye tracking apparatus revealed a good performance, in par with the gold standard, following the evolution of visual stimuli with sufficient accuracy, which ensures the suitability of its use in the context of gaze detection during rehabilitation. Conclusions: The validated gaze tracking ability, together with fact that both stimulus delivery and eye tracking is performed with the same device guarantees synchrony between both streams of data. Recorded videos of those signals allows for the design of new and personalized clinical evaluation and intervention strategies, to be applied throughout the rehabilitation program. Those may be used to complement physiotherapist’s evaluation of patients and allow for the identification of possible changes in their visuomotor skills.As an added feature, a new usability questionnaire was filled by a group of occupational therapists, which reinforced the potential use of the new version of RehabVisual, when applied to visuomotor rehabilitation of stroke patients.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"101 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":"129346383","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}

For example, a wide range of sensors were integrated in applications to develop a smart home, a mobile emergency response system and a fall detection system. Sensor technologies were also employed in clinical settings for monitoring an early sign or onset of Alzheimer’s diseases, dementia, abnormal sleep disorder, and heart rate problems. However, there has been a lack of attention paid to comprehensive reviews, valuable especially for young, early-career scholars who just developed research interests in this area. This paper reviewed the existing sensor technologies by considering various contexts such as sensor features, data of interests, locations of sensors, and the number of sensors. For instance, sensor technologies provided various features that enabled people to monitor biomechanics of human movement (e.g., walking speed), use of household goods (e.g., switch on/off of home appliances), sounds (e.g., sounds in a particular room), and surrounding environments (e.g., temperature and humidity). Sensor technologies were widely used to examine various data, such as biomarkers for health, dietary habits, leisure activities, and hygiene status. Sensors were installed in various locations to cover wide-open area (e.g., ceilings, wall, and hallway), specific area (e.g., a bedroom and a dining room), and specific objects (e.g., mattresses and windows). Different sets of sensors were employed to keep track of activities of daily living, which ranged from a single sensor to multiple sensors to cover throughout the home. This comprehensive reviews for sensor technology implementations are anticipated to help many researchers and professionals to design, develop, and use sensor technology applications adequately in the target user’s contexts by promoting safety, usability, and accessibility.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"2012 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":"128070395","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}

Nonetheless, AMRs still often face challenges when situations occur, which result in a failure of the navigation system. In this paper, we present an analysis and an implementation of a remote-control mechanism using 5G networks to enable an operator to control an AMR, in our example within a hospital, to support an AMR in situations, where an autonomous navigation faced challenges, that cannot be solved autonomously. In detail, four major challenges are faced when implementing a remote control for failure situations – the data connection itself, the sensor data acquisition and compression, the delivery of the current robot state for a user and the controllability of the robot. For autonomous driving, the AMR is equipped with a 128-layered 3D-Lidar sensor. An RGB-D camera facilitates video feedback for the operator to navigate the AMR manually. Additionally, the point cloud of the 3D-lidar provides a detailed in-depth view of the environment, which recognizes present persons or also allows the operator to drive backwards. To establish a connection between an AMR and a remote operator, a stable and low latency data connection is required. Since the Wi-Fi requirements of hospitals usually do not fit the requirements of remote-controlled robots regarding data security, network coverage, connection latency and bandwidth, the usage of the Wi-Fi network of hospitals is not appropriate. These challenges can be overcome using 5G cellular network to guarantee a low latency, high bandwidth connection which is independent from the regulations and limitations of the local Wi-Fi network. Nonetheless, by selecting the cellular 5G network as the remote operation network, further challenges arise – e.g. coverage of the 5G network or the stable and secure accessibility of the robot. Since hospital building structures are complex and usually are constructed using reinforced concrete, 5G radio waves are reflected or absorbed. In addition, the bandwidth is limited, since a public cellular connection is used. Due to these limitations, data compression is required for transmitting large chunks of sensor data, such as RGB camera streams or point clouds. The RGB video compression is implemented using the H.264 codec, which again can be accelerated using hardware. The point cloud is compressed through an octree implementation. As a result, the sensor data is transmitted with low latency and less lag. Despite using data compression algorithms, which are not lossless, the quality of the sensor data, received by the operator, is still sufficient for remote control operations. For a safe and controlled remote control of an AMR using the above explained technology stack, a data connection with less to no data transfer loss is required.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"13 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":"130527212","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, it has been identified the difficulty that students have when they need to solve addition and subtraction math problems with numbers of up to three digits, which is why it is necessary to find new ways to teach students to reason. This article proposes the design of a board game to strengthen logical reasoning. The methodology used in the research began with a diagnosis of 37 fourth grade students from a private school in Ecuador through a pre-test, later an interaction with the board game and finally a post-test. Two math teachers and two designers participated in the board game design. The information obtained from the experts helped with the design of the game, the data collected from teachers made it easier to identify the main problems that students present in terms of understanding mathematical problems. The design of the game was based on the narrative of superheroes such as: Spidermas, Superesta, Dividivertido, Centella, Sumager, among others, as well as in the most representative places at the Downtown of Quito. The game is designed for three or four students; the game’s mechanics consist in that the participants must solve math problems proposed in the board and if they can solve them properly, they advance in the game. Among the main results and conclusions of this research is that the students feel motivated to learn using the game; in addition, collaborative work is evidenced, and soft skills are enhanced such as teamwork, problem solving, analytical thinking and autonomy. For future work, the board game can be used in other topics where students face difficulties, such as: fractions, multiplication and division.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"34 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":"132550855","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}
