After the epidemic, the meaning of the word \"takeaway\" was extended from catering to food delivery, medicine delivery, and all kinds of necessities, and the takeaway delivery gradually accompanied the new retail consumption habits developed by users during the epidemic. In the whole service system of take-out delivery, with the increasing number of take-out delivery personnel, the take-out delivery e-bikes used are still ordinary travel e-bikes, lacking consideration and design of user behavior and usage scenarios. In the context of the new national standard \"electric bicycle safety technical specifications\" policy, there are still many takeaway delivery using electric bicycles do not meet the specifications, due to the delivery of limited time to arrive, a one-time delivery of overloaded goods and other cases of traffic accidents caused by frequent. This study introduces the KANO model and hierarchical analysis and TRIZ theory to study the real needs of users, and seeks to conduct innovative design research on take-away delivery electric bicycles.In the preliminary stage of the study, the secondary data research method was used to conduct preliminary summary research on a variety of businesses extending from the take-out industry, and the delivery process of riders in the take-out industry service system after receiving orders was derived through observation, interview, focus group discussion, and questionnaire research methods. Based on the KANO model framework to classify and prioritize user requirements, the non-linear relationship between product features and user satisfaction is identified based on the analysis of the impact of user requirements on user satisfaction. Recognize product and service requirements from the user's perspective, design and publish a valid questionnaire, summarize and classify the survey results, and build a quality model. Further research and analysis of the quality model to identify the sensitivity of specific measurement indicators. Combined with the hierarchical analysis method, the elements within the same level are compared in two-by-two analysis to determine their respective weights for the previous level, and finally give the importance ranking of all factors relative to the total goal, and finally tap into the real user needs. The TRIZ theory is then used to provide systematic theoretical and methodological tools for problem transformation, analysis and solution of needs creatively using innovative thinking methods and problem analysis methods, following the laws of technological system evolution. The KANO model and hierarchical analysis method are effectively combined with TRIZ theory to gradually quantify the qualitative analysis, which can generate more objective research data conclusions and provide innovative ideas ","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"19 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":"126747698","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}

Merchants have also begun to expand multi-scenario and flexible real-time delivery services to meet different scenarios and consumer needs in a cost-effective manner. The rise of the \"lazy economy\" of the Z generation has also made instant delivery the \"sweet pastry\" in the Internet industry. In the past ten years, the agent driving market has flourished under the impetus of Chinese Internet companies, and with the changes in user needs, it has also extended to travel agent driving, business agent driving and other agent driving scenarios. However, with the normalization of the epidemic and the continuous changes in user needs, the agent driving industry is also facing considerable challenges. The specific problems are as follows: (1) In recent years, contemporary young people have changed their night lifestyles, the culture of workplace wine bureaus have become indifferent, and national control under the epidemic has caused KTV, bars and other entertainment venues to shut down one after another. The decline in the total market for drinking and drinking has forced the agency driving industry, which is dominated by the business of drunk driving, to find a second growth curve. (2) The driving products of various platforms are gradually becoming the same to a certain extent, and it is difficult to experience product differentiation. (3) With the substantial growth of the luxury car and new energy car market, the consumption level of head users of car-on-demand services has risen, and the existing car service market is showing a disconnection of the service link, which is in urgent need of digital transformation. Head users also put forward multi-scenario service requirements for on-demand driving. Therefore, broadening the service scenarios of the agent driving business, reversing the minds of users about driving on behalf of the drunk, and meeting the needs of users on behalf of the scene is the current research focus of scholars. Enterprise D is a global outstanding mobile travel platform, and its agent driving business is a branch of its business. The company’s current agent driving business is gradually being squeezed by a crowd of competing products due to its high service quality and high cost. The user's mind on the brand is still stuck in drunk driving, which makes it difficult to achieve breakthrough growth in GMV . This research takes D enterprise’s agent driving products as the research object, and conducts product expansion planning and research on its agent driving business through QFD theoretical methods. First of all, conduct scenario analysis and hierarchical decomposition of D enterprise’s customer needs. According to the principle of user demand analysis method KANO , analyze the current consumption needs and characteristics of D enterprise’s customers and potential customers, and determine the importance of user needs.

The intermediate values of the positions of each type of element in the book cover in the sample were obtained, and then the initial positions of each type of element in the experimental elements were assigned according to the recognition results. And then this paper proposes an automatic displacement algorithm by generating random class objects with random seeds and then generating random numbers with the help of this object so that the objects can be displaced irregularly on the page to produce a large number of combinations with high aesthetic values. In order to verify the effectiveness of the automatic layout method given in this paper, the book cover layout is generated on the basis of the random given element size and the higher interface aesthetics values are calculated.","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"39 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":"132396131","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}

To more accurately understand the relatively real user experience of BEV, this paper uses text mining and natural language processing based on the big data text of BEV user experience and proposes a method for collecting, drawing, and analyzing these user experiences. In this way, the user experience of the real scene can be restored to a certain extent. The content includes are following. Firstly, obtain user comments on the typical BEV Model 3 on the online review website through crawler software, and use natural language processing technology to pre-process the data. Secondly, based on the constructed stop word database, the texts in the text stop words are eliminated. Then, the number of common occurrences between two adjacent words is counted, and a co-occurrence matrix is generated. Finally, word frequency statistics, improved TFIDF keyword extraction is performed; and keyword word cloud, centrality analysis, multi-scale keyword analysis are visualized. Compared with the traditional research focusing on individual user experience, this research explores the possibility of a research method of user experience evaluation in the context of big data. This will provide a certain theoretical reference for the research of the user experience evaluation system, and help the product user experience team of related BEV to get closer to the truth to understand the user's experience scenarios, behaviors, and real feelings.","PeriodicalId":409565,"journal":{"name":"Usability and User Experience","volume":"14 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":"133447572","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}

Aligning Applied Human Factors Engineering (AHFE) with visual rhetoric can provide the field of UX with a deeper understanding of how a design can impact the effective performance and usability of products. According to Foss, visual objects are not inherently rhetorical, but when they are organized to express symbolic action, allow for human intervention, and target a specific audience, these visual systems gain rhetorical significance (Foss, 2004). All the various user interfaces (UI) that humans interact with day to day include attempts by a user experience (UX) designer to \"guide\" the user to the proven, most effective, lowest-risk means of accomplishing a specific goal. Aligning user experience (UX) with the principles of rhetorical theory establishes an important facet through which the designer can understand why a UI design fails or succeeds. Aristotle taught that the speaker accomplishes persuasion accomplished by appealing to the three pillars of rhetoric: logos (appealing to logic), pathos (appealing to emotions), and ethos (appealing from authority).Similarly, Don Norman stated (2013), \"Cognition provides understanding, and emotion provides value judgement.\" Norman also discussed (2003) that trust in the UI is damaged when UI doesn't meet these cognitive and emotional expectations. Consider an experience many Americans have in common, staying overnight in a hotel. Every hotel works similarly, understood through the hotel business's well-established practices and expectations built on previous experiences. But imagine what transpires when the experience breaks convention and the unexpected happens. Incorporating rhetorical principles in design considers how users identify and communicate to others in their user group. Appealing to the users through logos, pathos, and ethos helps the designer communicate more effectively, meeting the user's needs. When these pillars work together to communicate with the user more accurately, it improves a user’s discoverability of product features, and system affordances become a pleasant, straightforward experience to enhance the usability of products. High-usability products correlate to reduced cognitive load, task time reduction, and reduced fatigue time. Foss et., Helmers, Marguerite H., and Charles A. Hill. Defining Visual Rhetorics.

The methodology includes a meta-analysis of current literature and content analysis of social media content on the subject matter. The meta-analysis revealed that positive attitudes about facial recognition technology used in schools only reflect a portion of the total surveyed. A sentiment analysis of tweets about facial recognition technology used in schools and universities revealed that concerns skyrocketed in 2020, probably caused by the pandemic forcing courses and academic activity online, thereby heightening awareness about facial recognition technology and its implications. Tweets expressed concern about privacy, ethics, and data management. Negative emotion spiked in discussions about unrest and conflicts, possibly due to news about facial recognition used in crowd control. Concerns about power differentials spiked in conversations about how facial recognition would affect academics and education. The trends in attitudes directly pertain to current and projected problems and negative implications of facial recognition on vulnerable populations, including children, seniors, ethnic minorities, and transgender populations. The heterogeneity of the U.S. market requires sensitivity to issues of diversity, equity, and inclusion. Recommendations include operationalizing lessons learned from user experience research.
