HUMAN-COMPUTER INTERACTION: ENHANCING USER EXPERIENCE IN INTERACTIVE SYSTEMS

In this research, we investigate how human-computer interaction (HCI) can be used to improve the user experience (UX) of interactive systems. Studies in cognitive psychology, information processing, and human factors are examined as they relate to the development of HCI. It highlights how HCI has shifted its focus from functionality to user-friendliness, teaching ability, efficiency, enjoyment, and emotion. To better understand the current state of HCI and UX research, practice, and theory, a systematic literature study is performed. Focusing on users' goals wants, and characteristics at every stage of the design process is central to user-centered design (UCD) ideas and approaches, which are discussed at length in this article. We investigate usability testing as a crucial technique for bettering HCI, focusing on its advantages in pinpointing usability problems, boosting system efficacy, and boosting user pleasure. Methods for creating tests, finding participants, collecting data, and analyzing results are discussed. The importance of prototype methods in HCI and user-centric design is also emphasized in the study. This article delves into the practice of creating prototypes to collect user feedback, iterate designs, and perfect interactive systems. Techniques covered include paper prototyping, interactive wireframes, and high-fidelity prototypes. We propose interaction design frameworks like the User-Centered Design Process (UCDP) and the Double Diamond model to help designers prioritize users when developing interactive systems. The study also delves into how technologies like augmented reality, virtual reality, natural language processing, machine learning, and gesture-based interfaces have revolutionized HCI in recent years. The paper defends user-centric design's place in HCI, pointing out how UX affects user happiness, participation, and output. Researchers and practitioners in HCI and software engineering can greatly benefit from this paper's findings

Software Development Life Cycles and Methodologies:Fixing the old and adopting the new

Information Systems as a discipline has generated thousands of research papers yet practice still suffers from poor-quality applications. This research evaluates the current state of application development, finding practice wanting in a number of areas. Changes recommended to fix historical shortcomings include improved management attention to risk management, testing, and detailed work practices. In addition, for industry\u27s move to services orientation, recommended changes include development of usable interfaces and a view of applications as embedded in the larger business services in which they function. These business services relate to both services provided to parent-organization customers as well as services provided by the information technology organization to its constituents. Because of this shift toward service orientation, more emphasis on usability, applications, testing, and improvement of underlying process quality are needed. The shift to services can be facilitated by adopting tenets of IT service management and user-centered design and by attending to service delivery during application development

Transdisciplinarity seen through Information, Communication, Computation, (Inter-)Action and Cognition

Similar to oil that acted as a basic raw material and key driving force of industrial society, information acts as a raw material and principal mover of knowledge society in the knowledge production, propagation and application. New developments in information processing and information communication technologies allow increasingly complex and accurate descriptions, representations and models, which are often multi-parameter, multi-perspective, multi-level and multidimensional. This leads to the necessity of collaborative work between different domains with corresponding specialist competences, sciences and research traditions. We present several major transdisciplinary unification projects for information and knowledge, which proceed on the descriptive, logical and the level of generative mechanisms. Parallel process of boundary crossing and transdisciplinary activity is going on in the applied domains. Technological artifacts are becoming increasingly complex and their design is strongly user-centered, which brings in not only the function and various technological qualities but also other aspects including esthetic, user experience, ethics and sustainability with social and environmental dimensions. When integrating knowledge from a variety of fields, with contributions from different groups of stakeholders, numerous challenges are met in establishing common view and common course of action. In this context, information is our environment, and informational ecology determines both epistemology and spaces for action. We present some insights into the current state of the art of transdisciplinary theory and practice of information studies and informatics. We depict different facets of transdisciplinarity as we see it from our different research fields that include information studies, computability, human-computer interaction, multi-operating-systems environments and philosophy.Comment: Chapter in a forthcoming book: Information Studies and the Quest for Transdisciplinarity - Forthcoming book in World Scientific.

Applying tools for end of use outlook in design for recirculation

Circular economy is widely embraced as one major path towards sustainability goals by contributing to resource efficiency and reaching climate targets. The research need at hand lies in how to implement changes. To achieve a circular system, design for recirculation is advised when introducing new products and production processes. However, in practical applications it is a challenge to foresee the complex nature of a real circular production system with many stakeholders in a system in transition. Product systems are embedded in a use context, where the user is a key stakeholder. Collection and systematization of experience and ideas from the field is here a key. This research draws on the experiences of assessing and improve circulation in industrial practice deploying the Recirculation Strategies Decision Tree and the Eco-design-strategy-wheel. Through two case studies, practitioners have been supported in action to evaluate their products and production processes in term of circularity. Cases showed a process from current status and recirculation challenges to a more circular future state in production and end of life was scrutinized. As a result, emphasis differed between the two tools. The Eco strategy wheel supported product design phase with an engineering perspective, The Recirculation Strategies Decision Tree on end-of-life phase with a market perspective. Common for both tools was the dependency on user or operator\u27s handling. Outcome from this study is to emphasise the importance on social dimension in CE/user role in a circular product system. The interactive, user centered research with manufacturing companies is suggested for development to effectively close product loops

Towards a kansei-based user modeling methodology for eco-design

We propose here to highlight the benefits of building a framework linking Kansei Design (KD), User Centered Design (UCD) and Eco-design, as the correlation between these fields is barely explored in research at the current time. Therefore, we believe Kansei Design could serve the goal of achieving more sustainable products by setting up an accurate understanding of the user in terms of ecological awareness, and consequently enhancing performance in the Eco-design process. In the same way, we will consider the means-end chain approach inspired from marketing research, as it is useful for identifying ecological values, mapping associated functions and defining suitable design solutions. Information gathered will serve as entry data for conducting scenario-based design, and supporting the development of an Eco-friendly User Centered Design methodology (EcoUCD).ANR-ECOUS

Living Innovation Laboratory Model Design and Implementation

Living Innovation Laboratory (LIL) is an open and recyclable way for multidisciplinary researchers to remote control resources and co-develop user centered projects. In the past few years, there were several papers about LIL published and trying to discuss and define the model and architecture of LIL. People all acknowledge about the three characteristics of LIL: user centered, co-creation, and context aware, which make it distinguished from test platform and other innovation approaches. Its existing model consists of five phases: initialization, preparation, formation, development, and evaluation. Goal Net is a goal-oriented methodology to formularize a progress. In this thesis, Goal Net is adopted to subtract a detailed and systemic methodology for LIL. LIL Goal Net Model breaks the five phases of LIL into more detailed steps. Big data, crowd sourcing, crowd funding and crowd testing take place in suitable steps to realize UUI, MCC and PCA throughout the innovation process in LIL 2.0. It would become a guideline for any company or organization to develop a project in the form of an LIL 2.0 project. To prove the feasibility of LIL Goal Net Model, it was applied to two real cases. One project is a Kinect game and the other one is an Internet product. They were both transformed to LIL 2.0 successfully, based on LIL goal net based methodology. The two projects were evaluated by phenomenography, which was a qualitative research method to study human experiences and their relations in hope of finding the better way to improve human experiences. Through phenomenographic study, the positive evaluation results showed that the new generation of LIL had more advantages in terms of effectiveness and efficiency.Comment: This is a book draf

STAR framework revisited: Curriculum for user-centered design summer schools

Annually, an interdisciplinary community of students, researchers and practitioners from computer engineering, social sciences, Human Computer Interaction, visual communication and other related disciplines, gather together for 2-to-5 weeks to participate in intensive summer school sessions. Although the overall theme and the participants vary each year, these programs remain focused on the teaching and practice of User-Centered Design (UCD) in the context of the local community where the academy is conducted. By listening to lectures, working in ateliers, living with target users and facing real-world design problems, participants experientially learn a mixture of IxD processes, ethnographic methods, prototyping techniques and teamwork skills, despite the program's short duration. Intensive design summer academies like this are essential, as they offer an environment for experimentation that is difficult to create in other educational settings. However, organizing and implementing these programs in ways that optimize the learning process is challenging. As past participants, atelier leaders and instructors for a variety of summer workshops, the authors made several poignant observations about the need for an educational framework to facilitate learning and to address the students' diverse cultural backgrounds, educational disciplines, learning techniques and cultural markers. Upon further examination of the educational literature, ethnographic observation during subsequent summer sessions and interviews of past students, atelier leaders, lecturers and organizers, the authors proposed the STAR Framework for design summer schools. [see Schadewitz, Adler, Moncur, Roberts, 2006] While this framework offers organizers clear direction on structuring IxD summer schools, it provides little guidance on the curriculum itself. It has become clear that special attention must also be paid to the content, order and delivery of the curriculum, particularly given the limited time frame of the session. Building upon the established framework, this paper proposes a curricular construct that will maximize knowledge transfer within the summer school context

Creating Technology-enhanced Practice: A University-Home Care-Corporate Alliance

Insuring full benefit of consumer health informatics innovations requires integrating the technology into nursing practice, yet many valuable innovations are developed in research projects and never reach full integration. To avoid this outcome, a team of researchers partnered with a home care agency’s staff and patients and their corporate parent’s Information Systems and Research group to create a Technology-Enhanced Practice (TEP) designed to enhance care of home bound patients and their family care givers. The technology core of TEP, the HeartCare2 web site, was built in a collaborative process and deployed within the existing patient portal of the clinical partner. This paper describes the innovation and the experience of bringing it into full operation

Agile Requirements Engineering: A systematic literature review

Nowadays, Agile Software Development (ASD) is used to cope with increasing complexity in system development. Hybrid development models, with the integration of User-Centered Design (UCD), are applied with the aim to deliver competitive products with a suitable User Experience (UX). Therefore, stakeholder and user involvement during Requirements Engineering (RE) are essential in order to establish a collaborative environment with constant feedback loops. The aim of this study is to capture the current state of the art of the literature related to Agile RE with focus on stakeholder and user involvement. In particular, we investigate what approaches exist to involve stakeholder in the process, which methodologies are commonly used to present the user perspective and how requirements management is been carried out. We conduct a Systematic Literature Review (SLR) with an extensive quality assessment of the included studies. We identified 27 relevant papers. After analyzing them in detail, we derive deep insights to the following aspects of Agile RE: stakeholder and user involvement, data gathering, user perspective, integrated methodologies, shared understanding, artifacts, documentation and Non-Functional Requirements (NFR). Agile RE is a complex research field with cross-functional influences. This study will contribute to the software development body of knowledge by assessing the involvement of stakeholder and user in Agile RE, providing methodologies that make ASD more human-centric and giving an overview of requirements management in ASD.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED
