   2. User-Centered Detection of Fake News and Misinformation - Design and Prototypical Implementation in the System Contexter

      Kurt Englmeier

      Abstract

      Misinformation or fake news may threaten our democracies, societies, and economies, even individual health and well-being. Humans are usually careful about the things they are being told. They check news or tweets against their knowledge or beliefs and estimate to what extent propositions contain information that is bogus. People have abstract representations of facts in mind. That help them to validate propositions and to search for information suitable for their validation. This paper presents design and prototypical implementation of the Contexter system that enables users to define and manage blueprints of facts or fake news. Contexter takes these blueprints as a schema to detect facts or fake news. It also starts to find variants of these blueprints to detect pieces of text that come semantically close to the propositions addressed by the original blueprint.

      Alberto Vergnano, Andrea Piras, Francesco Leali

      Abstract

      Car driver and occupants monitoring is important for safety and comfort. The systems using vision sensors for monitoring the line of sight can be integrated with pressure sensors embedded in the seats to identify critical Out of Position conditions. A new modular car seat is here proposed to monitor the pressure distribution on different significant regions. The solution improves the limitations of existing technologies embedded in seats. The proportional and fast measurement enables online complex evaluations, while the layout reduces the risk of errors. The experiments proved the effectiveness of the prototype.

   4. Technical Challenges to Adopting Large Scale Additive Manufacturing for the Production of Yacht Hulls

      Eric Peterson

      Abstract

      Recent developments in additive manufacturing technology may initially appear as an emerging opportunity for multiple manufacturing sectors, but there are several serious challenges to the potential application of additive manufacturing with Fiber Reinforced Plastic (FRP) to the yacht design and manufacturing industry. While several boat hulls have been produced using additive manufacturing technologies such as the 3Dirigo demonstration project built at the University of Maine [1], vessels of this type remain experimental prototypes that will require additional testing before the technology proves commercially viable as a construction method. The example of Thermwood’s Large Scale Additive Manufacturing (LSAM) system to successfully produce a small yacht hull plug mold is a promising application for 3d printing in yacht manufacturing [2]. Other applications of additive manufacturing technology to yacht components have proven viable, especially for small-scale replacement parts and retrofit components [3]. These initial steps into additive manufacturing are promising advances for the yacht design and manufacturing sector, but serious technical challenges remain before FRP hulls can be produced using additive manufacturing technology.

   5. Human-Machine Interactions for on the Fly Free Text Input Processing

      Sergius Dyck, Almuth Hoffmann

      Abstract

      Information in machine-readable form has to be entered by users of information systems in various situations. In the input process, forms with a number of individual fields are commonly used. For the creator, this input can be cumbersome and potentially counterintuitive. For this reason, free text components are becoming increasingly important. Information in the form of free text is not machine-readable as such, and extracting information is complex. The accuracy of existing approaches used to extract information from free text components depends directly on the quality of the used internal model. These models have to be created by experts or trained in advance using the appropriate machine learning methods. The main objective presented in this paper is extracting information as well as enhancing the underlying model on the fly. This implies that the information extraction algorithms apply directly to the user’s input and that the user is enabled to correct possible deficiencies in the model as they arise.

   6. Cork as a Relevant Material in Fashion: A Study of Socio-Cultural Trends and a Semiotic Reading of the Cork-a-Tex Yarn

      Theresa Lobo, William Afonso Cantú, Nelson Pinheiro Gomes

      Abstract

      The main objective of this research is to understand the symbolic and cultural readings that the Cork-a-Tex yarn can have as a new fashion design textile. The methodology is divided into two parts: literary review and analysis. The literary review contextualizes the main themes of this paper and the analysis approaches both semiotic and trend methods, framing the case study as a ‘cool signal’ of socio-cultural trends. Both analyses contribute to a cultural reading of meanings behind the case study and promote a better perception of contexts and mindsets. Through this combination of methods, we understand the framework of meanings imprinted on the object. Understanding its cool nature and association with trends reinforces the need for developments of new materials from cork and stimulates research on socio-cultural trends.

   7. Psychological Interpretation of Human Social Behaviors in the Atypical Architectural Shape

      Young Lim Lee, Yun Gil Lee

      Abstract

      This study is the continuation of our previous study and concerns the development of a system that simulates human behavior for use in the design process for an atypical space. This paper aims to identify the psychological causes of human social behavior in atypical architectural geometry, which are essential for the development of a human behavior simulation system. Users interact both individually with a building’s shape and socially with others within an atypical building, and it is necessary to grasp both the form of social action taking place in an atypical space and identify the cause of that form in order to lay the foundation for computerization. In order to analyze the causes of social behaviors of users in an atypical space, we first looked at the actual social behaviors. A representative case was drawn from the results of a survey. Then, a psychological interpretation was attempted based on the literature review. This paper’s primary concern is with the psychological interpretation, and the second half presents a proposal for applying the psychological interpretation to a social behavior simulation system. The results of this study can be used as a foundation for technology that can be integrated into the previously developed ActoViz system to realize a more appropriate simulation for user behavior.

   8. Automatic Summarization Method for First-Person-View Video Based on Object Gaze Time

      Keita Hamaoka, Yasuyuki Kono

      Abstract

      Several first-person lifelog videos are lengthy in duration, and often include scenes that are not useful. This can be problematic for users as it requires a considerable amount of time to watch such a video. Therefore, in this study, we propose an automatic video summarization system for first-person-view videos by employing gaze tracking and object detection, based on human gaze time on an object. Because gaze is useful for capturing a user’s intention and interest, our approach summarily captures their interest and conscious focal points while watching videos. As a result of the experiment, the evaluation value of the summary video generated by the proposed system exceeded that of the summary video in which important scenes are randomly extracted. From these results, it can be said that our system is useful for rapidly watching videos, and summarizing them to reflect user interest. Our system is applicable in many fields, including behavior recognition, visual diary creation, and support for patients having memory impairment.

   9. Modelling the Adoption of the Version Control System: An Empirical Study

      Tihomir Orehovački, Darko Etinger, Snježana Babić

      Abstract

      Version control system is a repository of a source code that provides support in all stages of a software development lifecycle. Success of a version control system is affected by its acceptance by end-users. This paper deals with the adoption of the distributed version control system. With an aim to determine antecedents of satisfaction with as well as behavioral intention related to the reuse of the version control system, we proposed a research model composed of constructs that originate from several theories and models including technology acceptance model, theory of reasoned action, and expectation-confirmation theory. An empirical study was then carried out and was composed of two parts. First, study participants had to complete scenario-based interaction with GitHub as a representative sample of distributed version control systems. As a follow up, study respondents had to fill out the post-use questionnaire. Students from two higher education institutions were included in the study as a representative sample of users. The psychometric features of the research model were examined by means of the partial least squares structural equation modelling method. Study findings uncovered implications for both researchers and practitioners.

   11. Task-Technology Fit and Continuance of Use of Web-Based Programming Tool: A Pilot Study

       Igor Škorić, Tihomir Orehovački, Marina Ivašić-Kos

       Abstract

       Web-based coding tools are widely accepted in computer science education. The use of these tools allows us to improve learning, but the requirement is to understand the factors that affect their acceptance. Carefully selecting technology that best suits the needs of the task will allow the optimal use of these tools in education. The purpose of this study is to develop a model that incorporates constructs of the Task-technology fit (TTF) model and the Expectation-confirmation model of IT continuance (ECM) to better understand the impact of the tool’s suitability on the user’s behavioral intention. The analysis was performed using the partial least squares approach to structural equation modeling. The results show a significant impact of task-technology fit factor on student satisfaction and their continuance intention. Consequently, this demonstrates that the proposed model is appropriate for understanding the acceptance of web-based programming tools in an educational context.

       Lilia Raycheva, Neli Velinova, Nadezhda Miteva, Mariyan Tomov

       Abstract

       The COVID’19 pandemic has led to drastic changes in people’s lifestyle around the world, incl. those related to the natural way in which individuals interact and communicate. In order to examine some of the effects of virtual communication during the social isolation, an academic research team from the Faculty of Journalism and Mass Communication at The St. Kliment Ohridsky Sofia University of Bulgaria undertook a study in the declared two-month’s period (13.03.–13.05.2020) of the state of emergency in the country. The researchers conducted a three-folded study: on the sociological polls and the media coverage during the pandemics; on the impacts of virtual communication during the social isolation, using mixed methodology: quantitative and qualitative survey with three groups of respondents: media users, media professionals and media experts; and on the activities of the telecommunication industry. The results of the effects of virtual communication in social isolation were indicative.

   13. Managing Strategic Participation Through Design Principles: A Model for Value Co-Creation in Service-Based Organizations

       Rocío Salvatierra

       Abstract

       Even though it is well-known that co-creation generates opportunities and benefits for organizations, there is still a void in literature concerning participation management practice. This generates mistrust and blurred understandings about it’s strategic relevance. This paper presents three models to manage participation through design principles to close the gap between participation as a mindset and participation as a practice of value co-creation. Participation is a scale and each level refers to the depth in which actors are involved in a certain process, initiative or project and, therefore, the level of engagement they reach. It must be strategically managed through time and with the full spectrum of actors that build a service-ecosystem so as to achieve collaboration and multidimensional value.

       Dehua Yu

       Abstract

       The aim of this interaction exhibition of mortise and tenon structure of Chinese traditional furniture is to display the exact and exquisite structure of mortise and tenon and increase the interaction between visitors and the exhibits. All the visitors have chances to participate in the fixing and unfixing process of real mortise and tenon directed by virtual installation instruction. The first plan is to project the installation instruction animation on the wall with the aid of sensor technology. However, the interaction animation can only be displayed on the wall. The second plan is mix real mortise and tenon structure and virtual installation instruction together, while participants would immerse in the real and virtual surroundings with the aid of MR glasses. The experience process is easy and interesting without pressure, although some mortise and tenon is complicated to a certain extent.

   15. Exploring Annotations and Hand Tracking in Augmented Reality for Remote Collaboration

       Tiago Madeira, Bernardo Marques, João Alves, Paulo Dias, Beatriz Sousa Santos

       Abstract

       Collaboration among remotely distributed professionals is often required in a maintenance context. Professionals need mechanisms with adaptive capabilities to enable knowledge transfer, since the necessary experience and expertise are usually spread among different professionals. To provide a shared understanding, Augmented Reality (AR) has been explored. In this paper, which is part of ongoing research using a human-centered design approach with partners from the industry sector, we describe a framework using annotations to improve the shared perceived realities of different professionals. The framework allows manually freezing the on-site professional context and sharing it with a remote expert to create annotations. Then, the on-site professional can visualize instructions through aligned and anchored annotations, using a see-through Head Mounted Display (HMD). In addition, annotations based on real-time video stream from a remote expert are also available. Hand tracking is used to manipulate the annotations, enabling the adjustment of their position and scale in the real-world according to the context, thus enriching the on-site professional experience and improving visualization of information while conducting maintenance procedures suggested by a remote expert.

However, young people do not have complete cooking skills because of poor experience. This paper focuses on their cooking problems and applies user research approach to concluding the pain points of cooking behavior for this cohort of young-adult users. The purpose is to provide users with easy, intuitive, and interesting cooking instructions. Based on the interactive projection technology, we developed a cooking interactive projection system named “Homenu”, which has a lightweight and natural interaction.

   17. Process Design for Evoking Emotional Response Focusing on Empathy

       Akane Matsumae, Mitsuki Miyahara

       Abstract

       This study attempts to improve video viewing experiences by elucidating the mechanisms of evoking emotional responses focusing not on the video itself, but on the cognitive state of the viewers. The authors focused on empathy, which is considered to be the most important factor in evoking emotional responses, affected by the amount of both knowledge and engagement. The comparative experiment was conducted between two groups: one group was asked just to watch the video; the other group was asked the same but after experiencing a workshop where they were given an opportunity to acquire knowledge of and engage with the video subject matter. As a result, the participants with greater knowledge and engagement before viewing the video displayed a significantly higher level of emotional response on average. The knowledge obtained from this study will contribute to the improvement of the design process to evoke an emotional response in video viewing.

   18. Humanoid Robotics: Guidelines for Usability Testing

       Niccolò Casiddu, Francesco Burlando, Claudia Porfirione, Annapaola Vacanti

       Abstract

       In the macrofield of human–computer interaction, human–robot interaction (HRI) is a relatively new and unexplored field of study. As several efforts have been made in robotics to expand the range of functionalities of hardware and software, perhaps the hardest challenge is to ensure good usability and fluid interaction for users. With regard to remote operated robots, these aspects are unrelated and the interaction features may be taken into account at an advanced design stage. Nevertheless, when it comes to humanoid robots, interaction features are the keypoint, therefore the design of the latter should be driven by UX and UCD practices. The actual fact is that too little attention is paid to these issues or, at best, the latter are approached by IT’s point of view, who are in charge of the software development. In conjunction, a team of engineers take care of the mechanical parts and, in the most highly developed project, the appearance is curated by industrial designers. Given the importance of the interaction features, the design process should be rearranged in favour of the last-mentioned phase. However, the team in charge of this task should be composed of industrial designers, that we can consider as UI designers, along with UX expert. This study applies UX practices to the design process of a humanoid robot, providing practical guidance and guidelines to put in place usability testing during the various stages of development. Regarding testing, only user satisfaction is often investigated. Instead, the present approach includes an adaptation of typical elements of the web design area, such as learnability, efficiency, memorability and errors.

   19. Long-Distance Relationships: Use of Technology Advances in Communication, Idealization and Satisfaction

       Pamela Acosta-Rodas, Hugo Arias-Flores, Carlos Ramos-Galarza

       Abstract

       Long distance romantic relationships are becoming more and more common nowadays. There can be various concrete reasons that are the causes for this occurrence, among the most common, the pursuit of career opportunities, educational goals, military service, and migratory issues. The aim of this study is answering the question: how is possible to maintain this kind of relationship? This is explained from two variables: the first one refers to the technology advances which help the communication and the second one studied from the psychological periscope, the romantic idealization. It is approach the perception of this new type of relationships in the general population. Understanding technology influences in human life could help to develop more technological advances to the people to feel closer and to keep healthy relationships with themselves and the others, as well, it could bring lights to counseling and psychological therapy.

   20. Design of a Human Machine Interface for Programming and Testing Adjustable Frequency Drives for Constant Pressure Pumping Applications

       Byron Remache-Vinueza, Jefferson Castro-Ramírez, Mireya Zapata

       Abstract

       In this project, a human machine interface (HMI) was developed for programming adjustable frequency drives (AFDs). Frequency drives have a wide range of industrial applications such as pumping systems, conveyor belts, ventilation and air conditioning systems, and, in general, applications that require motors with high torque. Constant pressure pumping systems with AFDs, for instance, allow working with a proportional integral derivative (PID) control, providing the system with precise response between the desired value and the process feedback. In this project, an HMI has been designed to effectively configure, test and calibrate AFDs for constant pressure pumping applications. Various alternatives of HMI screens were analyzed using the prioritization matrix method to determine the most suitable screen. The HMI interface was developed in the DOPsoft 4 software of DELTA Electronics, following the guidelines set forth by ANSI/ISA-101.01-2015, to generate a clear and easy to understand HMI.

   21. Analysis, Evaluation, and Upgrading of a Data Analytics Methodology Through a Qualitative Evaluation Technique and a User-Centered Design Process

       Boris Astudillo, Katherine Cajilema, Marco Santórum, Jose Aguilar

       Abstract

       A data analytics (DA) methodology allows a proper treatment to obtain the best benefit from the data with the aim of allowing supported business decisions to be made. However, a DA methodology needs to be continually reviewed and updated to incorporate standpoint from researchers, in order to become the most efficient version. Our paper carried out an analysis and evaluation of the first phase of a selected DA methodology called MIDANO applying qualitative techniques to reach an improved version. The analysis and evaluation process were applied through a focus group discussion from the results obtained during the implementation of a case study. The upgraded DA methodology, as a result of the qualitative analysis, was related to the nine attributes extracted, classified, and validated from a user-centered design process previously studied, and based on ISO 9241:2010 standard, in order to obtain a DA methodology participatory, adaptable, efficient, collaborative, and easy-to-apply.

   22. A Revisit of Objective Measurement and Subjective Measurement: Basic Concept and Application

       Mengya Cai, Zhu Gao, Wenjun Zhang

       Abstract

       Measurement is foundational to learn, research, and design an artificial system. Precisely measuring human factors especially human mind in systems is a common and important problem. Basically, the measurement methods are categorized as either objective or subjective measurement. Recently, tendency is emerging that objective measurement is preferred widely but subjective measurement is despised. To judge the tendency, this paper revisited the basic concept of measurement first, and re-declared the definition of objective and subjective measurement. Tools of measurement were also discussed generally. Second, four criterions were proposed to judge a measurement, and a review of the debate between the two measurements shows that subjective measurement is the counterparts of objective measurement. Choice of one from the two depends on specific applications. This paper further discussed the application of subjective measurement. Three challenges were proposed which are still open to address. In conclusion, further researches on subjective measurement is indispensable.

       Ernesto Hernandez, Estrellita Calle, Miguel Hernandez, Ralph Rivera, Zury Sócola

       Abstract

       The virtual university education required by the global pandemic has promoted the use of virtual platforms such as moodle, which allows for permanent interaction with the student. The influence of the independent variable called “Emotional motivation” was measured, which has as a stimulus the application of a reading about all the biblical verses that mention wine, considering as a dependent variable “Empowerment of learning about wine technology” as well as in the levels of the variable: “Cognitive” and “Previous knowledge”. The objective was to determine if a relationship existed between both variables. In the results of the dependent variable, there was a decrease in the low and middle levels; and an increase in the high level. Applying results of the pre-test and post-test, the chi-square test determined that in the dependent variable, if there is significant difference so the alternative hypothesis is accepted and the null hypothesis is rejected.

   24. Design Narrative and City Information Modeling

       Gonçalo Falcão, José Beirão

       Abstract

       This paper connects researchers from two different areas of expertise – Architecture/CIM (City Information Modeling) software and Design – by using the concept of the Trojan Horse to develop a common project. The concept is used experimentally to get a different insight on these two knowledge areas and as a method to research the impact of scientific knowledge on the two specific academic communities by intersecting very specific digital features from both knowledge areas. Computer analysis can help to stop or at least mitigate human failures as methods and analysis can be speeded up immensely. This research stems from a conversation between CIM and Design to improve the city analysis and modeling tools by looking into design thinking and design methods as a means for searching for better interfaces and human systems integration.

   25. Designing Synthetic Emotions of a Robotic System

       Niccolò Casiddu, Francesco Burlando, Claudia Porfirione, Annapaola Vacanti

       Abstract

       As massive changes in our lifestyle and society structure are coming, due to the contemporary pandemic situation, we face more than ever the challenge of employing non-human and teleassistance devices in many areas, especially those that require assisting and caring for weak users. Humanoid robots are proven to be a valuable asset in these situations but require to be carefully designed in their interaction features, in order to be accepted and valuably used by their users. In particular, this study is focused on robots that have a certain degree of human-likeness that allows to define them “humanoids”; for this kind of robots we can say that the area devoted to replicate human facial features is the most important interface for human–robot interaction. Actually, more than 60% of human–human interaction is conducted non-verbally, by using facial expressions and gestures. For a robot to be able to engage in this kind of interaction with a human and provide understandable feedbacks is a massive step towards acceptance and development of an affectional relationship by users. Being meant to reproduce human emotions, visual feedbacks are mostly developed referring to eminent researches in the psychological field: as Paul Ekman already observed in 1998, human faces have a universal coding for six basic expressions that represent as many basic emotions: fear, anger, disgust, happiness, sadness and surprise. Our research focuses on the design of an expression system to be implemented in a European-funded project for an assistive robot that will support weak users at home or in assistance facilities and their caregivers. Our main concern regarding this project are to design a dynamic, human-friendly system that is scalable and visually recalls real facial expressions without being too much human-like, in order to avoid the well-known uncanny effect described by Masairo Mori.

   26. Relationship Between Gestalt and Usability Heuristics in Mobile Device Interfaces

       Daniel Ripalda, César Guevara, Alejandra Garrido

       Abstract

       While usability heuristics are universal concepts, visual references for using them in an application are limited, contradictory, and sometimes confusing, especially for novice developers. The present work has linked Nielsen’s heuristics with Gestalt principles, which are the foundation of human perception, developed from psychology, and which have been used in art, design, and architecture, to understand how different visual stimulus can be interpreted by the human being. The heuristics, Match between system and the real world, Recognition rather than recall and Aesthetic and minimalistic design, have been linked with the Gestalt principles of Similarity, Proximity, Common direction, and Simplicity. This link is possible because Gestalt principles have certain conceptual similarities with usability heuristics, in addition to the fact that these fundamentals were identified in some mobile interfaces and are related to specific interactions. This work provides theoretical guidelines, visual references and practical examples on the use of some graphic components that are regularly used in mobile interfaces, such as buttons, menus, and sections; Besides, information is provided regarding how these visual components affect certain usability interactions such as learnability, efficiency, memorability, and usefulness.

       Guillermina Dinora Suárez-Gómez, Alejandra Robles-Barba, Montserrat Avelar-Enciso, Carlos Raymundo Garnier-Ortiz, Fabiola Cortes-Chávez

       Abstract

       The objective of this study is to demonstrate the innovation and design process of a birthing bed, designed specifically for young first mothers [1]. This problem was chosen due to the social and cultural conditions nowadays in Mexico, which, according to data from the INEGI, National Institute of Geography and Statistics, around 32 million women over 12 years old pursue their motherhood [2]. Not only are the numbers alarming, but it must be addressed the fact that a poorly attended delivery can be truly traumatic. The data collected by primary sources is a series of surveys sent to mothers, doctors and nurses, in which they are questioned about their experience before, during and after delivery. They were also questioned about recommendations regarding actual delivery beds. Data collection via internet focused mainly in complementing the formation obtained in the surveys. The data in this investigation includes the complete process of a delivery, the actual birthing beds and the role of each user within a delivery.

       Mariana Diaz-Pinal, Julieta Ramirez-Reynoso, Mariana Ascencio-Murillo, Grecia Alejandra Chavira-Hernández, Fabiola Cortés-Chávez, Carlos Garnier-Ortiz

       Abstract

       The objective of this document is to show the development of the design of a portable birthing stretcher that facilitates the process of birthing in the indigenous communities of Mexico, to both the midwives and the mothers since the current conditions of birthing in the aforementioned place is insufficient to make it a safe and a comfortable delivery, it is worth mentioning that the midwives travel distances to be able to assist the mothers. For the design, we sought to ensure that it would not complicate the midwife’s transportation, but that it would also be a tool to transport all the necessary utensils for safe and hygienic delivery, as well as a device that would help with the mother’s posture so that she would be more comfortable during the delivery and would also help with the midwife to make it safer [1, 2].

   29. Birthing Bed with Ergonomic Design of Adjustable Sections by Touch Technology that Facilitates Its Understanding and Use

       Teresita Bátiz-Flores, Andrea Perez, María Fernanda Martínez-López, Fabiola Cortes-Chavez, Carlos Raymundo Garnier-Ortiz

       Abstract

       Labor is a complex process in which one of the main factors within the hospital’s context is the medical equipment that helps to carry out the work, such as the birthing bed. Is around it that the activities that allow an efficient labor are carry out. There are two main approaches when it comes to medical design, known as EBD (Evidence-Based Design) and UCD (User-Centered Design). Each one seeks to meet different expectations and functions with the design each supports. This article presents a comparative analysis on the design of a birthing bed using both approaches, aiming to know if an user-centered design methodology helps increase the satisfaction of the users, by improving the bed’s ease of use and understanding.
