Most of the group activities associated with this are conducted remotely, whichinvolves technological change affecting people, especially blind people. These videoconferencing platforms are hosted on the web, causing visually impaired users to enter a new era of communication with all its accessibility barriers and usability issues. For this reason, a systematic literature review (SLR) was conducted which allowed us to determine the level of web accessibility that these platforms have, the studies and all the implementations that are being conducted to mitigate this problem. In addition, the web accessibility of the three most widely-used videoconferencing platforms for both work and education was evaluated. Automated tools were used, individual tests were performed, accessibility guidelines (WCAG 3.0) were applied to determine the level of web accessibility, and usability tests were performed on a group of visually impaired individuals. The methods used were: Think Aloud (TA), the System Usability Scale Test (SUS) and Nielsen’s 10 Heuristic Usability Principles. The results of these tests and methods indicate that the selected videoconferencing platforms do not meet the minimum requirements for web accessibility, and that the level of usability is low. Therefore, changes need to be made and new implementations need to be developed with regard to these tools, so that visually impaired users can navigate the platforms smoothly and without any problems.","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"30 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":"114213447","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}

According to the current state of the art, the wide range of operating scenarios and changing operating characteristics can be covered only suboptimally by static control elements on the operating armrest. An optimized solution with intuitive operation, high usability and the avoidance of operating errors requires an HMI that can adapt optimally to the changing scenarios. Based on the previous research project aISA, the current project aISA 2.0 (adaptive interface systems in agricultural tractors) focuses on the development of an adaptive operating system in order to provide an optimal interface for the various and changing operating scenarios in tractors. Based on a methodical categorization, a design recommendation for the interface system is developed, among others considering availability, positioning, actuation type and interface technology of the functions examined. For this purpose, expert knowledge and a method for analyzing functionalities and operating is used. The existing method [1] will be further developed and applied to agricultural implements.METHODThe methodological approach can be divided into the following three aspects:1.Expert interviews2.Function and operation analysis, short: FOA3.Development of design recommendations for an optimized adaptive control system in agricultural tractors.In this contribution, the structure and results of the expert interviews are presented in detail. The expert interviews were conducted with developers from six different implement manufacturers regarding eleven different implements for a duration of 1.5 - 2 hours each. The objective was to gather every relevant control function and having each function evaluated by the expert in terms of different aspects. General settings, menu navigation and indicators not related to active controls were excluded. The next step involves analyzing the HMI by applying the established FOA based on the data collected. The individual functions are examined using operating scenarios. This includes comparing the control action performed by the user with the execution of the command by the machine. The analysis results in various compatibilities for each scenario that are necessary for intuitive operation. Based on the compatibilities, the current FOA is expanded including further specifications for the design recommendation of the control functions. This involves using 15 different control types that are available via the software interface (Isobus) commonly used in agricultural engineering. These define the framework for the type of operation on the software side that later can be performed by the adaptive control elements.RESULTSThe requirements for an adaptive operating armrest in agricultural tractors are achieved by the detailed analysis of the operating scenarios, the op","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"18 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":"125885981","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}

Faria, Célia Pinto, Emanuel Sousa","doi":"10.54941/ahfe1001702","DOIUrl":"https://doi.org/10.54941/ahfe1001702","url":null,"abstract":"The ubiquity of mobile phones and the advancement of their computational capabilities is making Augmented Reality more accessible to the general public. Being actively used in diverse domains (retail, mapping and navigation, education, maintenance and industry, entertainment, social media, etc.) Mobile Augmented Reality (MAR) can bring value to companies and provide enhanced user experience, when compared with traditional interfaces. Consequently, designers have been exploring the potential of this technology to assist people with their daily life activities and create meaningful experiences.When it comes to designing MAR experiences, what concepts should be considered? What are the best practices? What skills need to be mastered? In order to answer these questions a literature review on user studies that measure the User Experience of MAR applications was conducted. User studies were purposefully targeted because a user centered design approach has consistently shown that understanding peoples’ needs and expectations can improve existing products or assist the development of new ones. The aim of this study is to report a set of well rounded recommendations to help future researchers and practitioners to design better MAR solutions, present research gaps, and provide further avenues for research.Taking the objectives of the study into account, various search strings were constructed with key search terms (e.g. “augmented reality” AND “evaluation” AND “interface design” AND “mobile”). Based on the title and abstract, the search was conducted in September 2021 in Scopus, Web of Science and IEEE Xplore databases for peer review papers from journals between 2011 and 2021. Publications in small formats, literature reviews and technology-centric performance evaluations of algorithms were excluded. The initial research retrieved 62 papers — the abstract of each paper was analyzed. After removing duplicates, and applying the inclusion and exclusion criteria, 38 documents were excluded. Hence, 24 papers were eligible for analysis.After being assembled, the articles were read in full and reviewed in terms of their scope, research methods, procedures and outcomes. 29% of the publications dedicate a considerable amount of the document to report issues related to how the applications were built from a technological standpoint, and in some cases (37.5%) the sections that focus on the user studies lack detail. Therefore, it was not possible to draw elaborate conclusions from these papers in terms of the design process and evaluation. In contrast, few papers present highly detailed descriptions regarding methodological procedures. This information resulted in a list to support measuring MAR experiences. The role of emotions in MAR has captured the interest of researchers. Moreover, topics such as audio-augmented reality, affordances, storytelling and design principles are beginning to emerge in the literature.

The lack of interaction and communication in the experience design of online learning platforms has resulted in the forced weakening of the teacher's role, and the problem of lower student engagement and learning results has become increasingly evident which brings new requirements and obstacles to the design of online learning experiences.Since social presence has a direct impact on the effectiveness of online learning, which has been confirmed in the Col framework, this article will investigate user experience design in the context of online learning with the aim of enhancing users' social presence.User research methods, such as user interviews and questionnaires, are combined with theories associated with online learning to analyze the interaction experience design factors in the process of online learning, which are summed up as initial perception experience, learning process experience, and effect value experience. Second, the literature research technique is used to determine the formation mechanism and influencing factors of social presence: the formation of social presence depends on the triangle structure of \"sociability-social presence-social space,\" and the mapping relationship of \"social space orientation, perception of others, perception of self, evaluation of others and self, shared presence, perceived social presence\" can be summed and promotes the formation of social space and social interaction in turn.The influencing factors, including control, sensory, distraction and realism, are what finally build the link between experience and design. This research constructs an experience design model for online learning from the perspective of social presence based on the aforementioned research methods, and utilizes it as a basis to guide the design process, which is verified by applying the social presence evaluation scale.Based on social presence theory, this study suggests a model for experience design for online learning to direct design procedures that can satisfy users' needs for online learning, promote social interaction in online learning, optimize the online learning experience, and enhance learners' engagement and learning motivation. It offers fresh perspectives and a framework for experience design in this situation.","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"106 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":"122635767","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 is a continuation of the previous phase of the research and will design a prototype of a handheld device pertinent to a telecare system. The purpose of this study aims to investigate the user experience of telecare systems with handheld devices.In the previous phase of the study, most participants thought that the telecare system should have a clear information framework and function list to reduce the visual interference on the page and improve search efficiency. In particular, the functions in the \"System Functions, Find Consultant, Hot Consultants\" section should be clearly delineated. Therefore, the research design and experimental variables will primarily focus on the users' needs for remote care functions and the interactive menu interface design of the system. That is, the study will investigate the users' requirements for menu functions and the usability of the interactive interface of the system. The primary research method is a two-factor mixed experiment with a purposeful sampling method. Participants will be invited to take part in a usability test of the menu interface and will fill out a questionnaire after performing all typical tasks. Semi-structured interviews will be conducted with a representative sample of participants.After the experiment was completed, a two-way analysis of variance (ANOVA) will be conducted to investigate the main effects and interaction effect of the variables on the interactive user interface usability and users' subjective evaluations, such as psychological load, preference, and satisfaction. Through this study, it is hoped that the internal feelings of users when operating and interacting with the system can be understood via this study. The research results can be used as a good reference for future interface design of telecare system for handheld devices.","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"138 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":"123273449","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}

Recent reviews of evaluation practices found that while reports of evaluations are rising, algorithmic performance outweighs user performance as the dominant metric. This study sought to address this gap by engaging multiple categories of users informally evaluating the efficacy of a scientific visualization. Efficacy was evaluated for understanding, usability, and aesthetic value. Results indicate that aesthetics play a critical, but complex role in enhancing user understanding, particularly for non-expert viewers.Method Our center offers visualization services to scientists analyzing large volumes of complex data. This work motivated our need to evaluate scientific visualization from our users’ many perspectives. Our users need visualization for both: Collaborating with other specialists in their fields; Communicating results to non-specialist sponsors or public We designed a 2-phased study to include both audiences to evaluate a visualization of a research problem. In phase 1, participants evaluated a visualization produced collaboratively with the principal investigator (PI) of the research and our center. In Phase 2, participants evaluated the original visualization produced by the PI with no collaboration with our center. Visualization DescriptionThe U.S. Army is studying fuel atomization as it relates to heavy fuel engines relying on direct injection fuel delivery systems. The engines must significantly advance current fuel conversion efficiencies. The PI for the research created a visualization of the fuel atomization spray. The ERDC DAAC team designed a second visualization of the spray working iteratively with the researcher. Participants were shown an animation of that visualization. Participants were recruited from faculty, staff, and students across multiple disciplines at a university. Over the two phases of the study, 62 engineers, and 54 non-engineers participated. Participants were asked to watch videos of the visualization, answer questions about its content, and evaluate its aesthetic quality.The two-phase study directly compared the original to the enhanced visualization to determine the contribution of aesthetics to a viewer’s understanding of the research for engineers versus non-engineers. ResultsResults indicate that non-engineers viewed the original visualization as having poorer aesthetics and that enhancements to the visualization led to improved perception of aesthetics. These results suggest that improvements to aesthetics of a visualization may have a greater effect on non-engineers than engineers. For engineers, understanding of the research was not significantly improved when viewing the enhanced visualization. However, non-engineer performance matched engineer performance for the enhanced visualization. On the original visualization, non-engineers have a poorer understanding of the research than engineers.
