A Design of Human-Computer Interaction Based on Head Tracker

Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

Human-computer interaction (HCI) design is the modern and advanced research area that is focused on human or user and system or device interactions. HCI is concerned with new and advanced approaches to a system that must be reliable and efficient to the user. HCI design required a longer and critical development process, methods or framework that passes through various evaluation phases. Due to an inadequacy of user-centered and value sensitive design for a system or device, numerous designs and artifacts do not draw attention to the user. On the other hand, user perception of advanced and new devices are not acceptable and perceived, if not reliable or facile to them. HCI comprises several methods, principles, and criteria which are followed during the development of interaction design. Even then, at times the evolved new and advanced interaction artifacts are unable to reach the user attraction. The HCI methodologies promote the researchers as well as designers to form and develop new and advanced innovations whereas, interaction design term plays a significant role in the design process. In this paper, the key concern is to analyze the conventional design method, Activity Theory (AT) and consider the principles of HCI and bring in a conceptual extended AT model to develop the appearance of Human-computer interaction design.

Computational thinking (CT) skills are increasingly important in education to prepare students for the challenges of the digital age. Augmented Reality (AR) and Virtual Reality (VR) have been introduced as immersive technologies that have the potential to enhance CT skills through more interactive learning experiences. However, there is still a gap in understanding the effectiveness of these technologies in supporting the development of CT, particularly in different levels of education and disciplines. Although several studies have highlighted the benefits of AR and VR in education, no systematic review integrates these findings to identify advantages, challenges, and opportunities for further implementation. Therefore, this study conducted a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by analyzing 25 empirical studies (AR=17, VR=8) obtained from the Scopus database (2008-2024). The analysis addresses four key research questions: (1) the current state of AR/VR in CT development, (2) their advantages, (3) implementation challenges, and (4) future research directions. The results show that AR is more widespread than VR at various levels of education, with dominance in higher education followed by secondary and primary schools. Computer science is the main field of application of AR and VR, while AR is also widely applied in mathematics to increase interest and problem-solving. A total of 11 studies reported significant impacts of these technologies on CT, with AR being superior in increasing student motivation and engagement, as well as aiding in problem-solving and debugging. In contrast, VR provides a more immersive learning experience by strengthening concept understanding, especially in programming and recursion. However, several obstacles in the application of AR and VR, such as hardware limitations, costs, and user skills, affect the effectiveness of these technologies in the learning environment. This study also identified potential future research, including the exploration of VR in primary and kindergarten education, the application of VR in non-computer science fields, and the efficient use of these technologies in supporting the CT process. This study provides more precise insights into the optimal ways of utilizing AR and VR in developing CT skills. It is a reference for educators, policymakers, and researchers in supporting CT learning.

Spatial sound is rapidly becoming an important part of augmented reality (AR) and virtual reality (VR) applications. Microphone calibration is essential for providing spatial sound capture and reproduction capabilities in AR/VR. This paper presents RAndom PerturbatIons for Diffuse-field (RAPID), a precise method for the diffuse field calibration of the magnitude responses of microphones. The performance of RAPID is compared against the ground truth obtained using a well-established method utilising a two-axis turntable. Notably, it is possible to perform calibration using RAPID in 30 seconds, whereas calibration using the turntable method can take up to 4 hours. RAPID achieves similar results to the ground truth with significantly less effort and setup requirements. A tool is also available as an open source MATLAB application for performing RAPID calibration with ±0.5 dB accuracy.

There is a growing interest for the broad use of Augmented Reality (AR) and Virtual Reality (VR) in the fields of bioinformatics and cheminformatics to visualize complex biological and chemical structures. AR and VR technologies allow for stunning and immersive experiences, offering untapped opportunities for both research and education purposes. However, preparing 3D models ready to use for AR and VR is time-consuming and requires a technical expertise that severely limits the development of new contents of potential interest for structural biologists, medicinal chemists, molecular modellers and teachers. Herein we present the RealityConvert software tool and associated website, which allow users to easily convert molecular objects to high quality 3D models directly compatible for AR and VR applications. For chemical structures, in addition to the 3D model generation, RealityConvert also generates image trackers, useful to universally call and anchor that particular 3D model when used in AR applications. The ultimate goal of RealityConvert is to facilitate and boost the development and accessibility of AR and VR contents for bioinformatics and cheminformatics applications. http://www.realityconvert.com. dfourch@ncsu.edu.

Digital devices and online services are increasingly embedded within our everyday lives. The growth in usage of these technologies has implications for environmental sustainability due to the energy demand from the underlying Internet infrastructure (e.g. communication networks, data centres). Energy efficiencies in the infrastructure are important, but they are made inconsequential by the sheer growth in the demand for data. We need to transition users’ Internet-connected practices and adapt HumanComputer Interaction (HCI) design in less demanding and more sustainable directions. Yet it’s not clear what the most data demanding devices and online activities are in users’ lives, and how this demand can be intervened with most effectively through HCI design. In this thesis, the issue of Internet demand is explored—uncovering how it is embedded into digital devices, online services and users’ everyday practices. Specifically, I conduct a series of experiments to understand Internet demand on mobile devices and in the home, involving: a large-scale quantitative analysis of 398 mobile devices; and a mixed-methods study involving month-long home router logging and interviews with 20 participants (nine households). Through these studies, I provide an in-depth understanding of how digital activities in users’ lives augment Internet demand (particularly through the practice of watching), and outline the roles for the HCI community and broader stakeholders (policy makers, businesses) in curtailing this demand. I then juxtapose these formative studies with design workshops involving 13 participants; these discover how we can reduce Internet demand in ways that users may accept or even want. From this, I provide specific design recommendations for the HCI community aiming to alleviate the issue of Internet growth for concerns of sustainability, as well as holistically mitigate the negative impacts that digital devices and online services can create in users’ lives.

The emphasis of human-computer interaction (HCI) design on the technology and computer action tends to obscure consideration of the contribution of the computer interface to the service interaction. This chapter suggests that since a majority of commercial information systems support or provide services, the nature and progression of the service encounter should be a key concern of human computer interface designers. The chapter proposes the concept of service-oriented HCI in which HCI design is derived from service design, dialog is driven by customer needs and perceptions, activities that have led up to the service encounter are considered, and the service interaction dialog is aligned with the computer dialog. As part of service-oriented HCI, the chapter illustrates the use of scripting to examine ex-post the role of a computer interaction in a service encounter. It demonstrates that the computer dialog can drive the service interaction in such a way that the quality of the interaction is reduced and customer satisfaction affected. It concludes that the role of the computer system in a service interaction is an area for further research. Furthermore, script analysis may enable the development of human-computer dialogs that meet some of the criteria of service-oriented HCI.

In this paper, a method-mix (cultural dimensions, intercultural variables, user interface characteristics and human computer interaction (HCI) dimensions) for intercultural user interface design (IUID) is presented. Based on a hybrid approach covering cultural contexts in human–computer interaction (HCI) design using a model of culturally influenced HCI, this IUID method-mix represents the main constituent of a reasonable toolbox for IUID. The IUID method-mix is exemplified by application examples to demonstrate and discuss its benefit and limitations. The examples elucidate why and how cultural aspects play a role in HCI design and usability/UX engineering. Cultural influence on HCI is described using cultural variables for user interface design. The IUID method-mix serves to inspire HCI engineers in the requirement analysis phase as well as HCI designers in the design phase. The readers are sensitized to the challenges of intercultural usability/UX engineering and intercultural HCI design and will be equipped with relevant methodological knowledge needed to actively derive design recommendations for user interface design for and in their desired cultural contexts. Practitioners can prognosticate the ensuing effort and the expenditure for considering cultural context in intercultural user interface design.

Advanced three-dimensional extended reality (XR) technologies are highly suitable for cultural heritage research and education. XR tools enable the creation of realistic virtual or augmented reality applications for curating and disseminating information about cultural artifacts and sites. Developing XR applications for cultural heritage requires interdisciplinary collaboration involving strong teamwork and soft skills to manage user requirements, system specifications, and design cycles. Given the diverse end-users, achieving high precision, accuracy, and efficiency in information management and user experience is crucial. Human–computer interaction (HCI) design and evaluation methods are essential for ensuring usability and return on investment. This article presents ten case studies of cultural heritage software projects, illustrating the interdisciplinary work between computer science and HCI design. Students from institutions such as the State University of New York (USA), Glasgow School of Art (UK), University of Granada (Spain), University of Málaga (Spain), Duy Tan University (Vietnam), Imperial College London (UK), Research University Institute of Communication & Computer Systems (Greece), Technical University of Košice (Slovakia), and Indiana University (USA) contributed to creating, assessing, and improving the usability of these diverse cultural heritage applications. The results include a structured typology of CH XR application scenarios, detailed insights into design and evaluation practices across ten international use cases, and a development framework that supports interdisciplinary collaboration and stakeholder integration in phygital cultural heritage projects.

This paper presents the development of a learning-teaching methodology, based on the application of virtual and augmented reality. Its aim is to develop a teaching system based on immersive technologies containing 3D virtual environments. Lack of specialized workspace can be partially conciliated with the use of simulators for different areas of knowledge. Technical contributions of researchers in engineering areas are considered. The quality of the methodological design is verified through virtual laboratory sessions in simulated environments. Benefits of having these spaces include greater ease of access to laboratories when student populations are numerous, relieve in conducting controlled experiments without fear of experiencing equipment failures. For the execution of this work, bibliographic search on immersive methodologies applied to learning has been done. Works that contribute to virtual education, enhanced by the application of augmented reality, were selected. The second step has been the construction of a proposal of the teaching methodology for virtualized learning.

The challenges of designing computer support for education have shifted considerably in recent years, with, e.g., the rapid growth of the Web, online learning and social networking. New human–computer interaction (HCI) design approaches, methods, tools and theories are now required to analyze and understand interactions and learning of online groups. This chapter first reviews a number of issues related to the new software and pedagogy challenges. It then presents the approach of the VMT research project to address these issues by combining support for integrated synchronous and asynchronous collaboration media. The VMT system integrates a lobby, small-group chat rooms, multiple shared work spaces and community wiki pages to foster learning at the individual, small-group and community levels. The use of this system for a college HCI course is reported. The VMT Project illustrates the application of design-based research to system development, the theory of group cognition as a conceptual framework and an adaptation of chat interaction analysis for HCI design.
