Sonification with musical characteristics can engage users, and this dynamic carries value as a mediator between data and human perception, analysis, and interpretation. A user engagement study has been designed to measure engagement levels from conditions within primarily melodic, rhythmic, and chordal contexts. This paper reports findings from the melodic portion of the study, and states the challenges of using musical characteristics in sonifications via the perspective of form and function – a long standing debate in Human-Computer Interaction. These results can guide the design of more complex sonifications of multivariable data suitable for real life use.

Purpose This study aims to propose a service-dominant logic (S-DL)-informed framework for teaching innovation in the context of human–computer interaction (HCI) education involving large industrial projects. Design/methodology/approach This study combines S-DL from the field of marketing with experiential and constructivist learning to enable value co-creation as the primary method of connecting diverse actors within the service ecology. The approach aligns with the current conceptualization of central university activities as a triad of research, education and innovation. Findings The teaching framework based on the S-DL enabled ongoing improvements to the course (a project-based, bachelor’s-level HCI course in the computer science department), easier management of stakeholders and learning experiences through students’ participation in real-life projects. The framework also helped to provide an understanding of how value co-creation works and brought a new dimension to HCI education. Practical implications The proposed framework and the authors’ experience described herein, along with examples of projects, can be helpful to educators designing and improving project-based HCI courses. It can also be useful for partner companies and organizations to realize the potential benefits of collaboration with universities. Decision-makers in industry and academia can benefit from these findings when discussing approaches to addressing sustainability issues. Originality/value While HCI has successfully contributed to innovation, HCI education has made only moderate efforts to include innovation as part of the curriculum. The proposed framework considers multiple service ecosystem actors and covers a broader set of co-created values for the involved partners and society than just learning benefits.

Computer Interaction

A critical determinant of message interactivity is the presence of contingency, that is, the messages we receive are contingent upon the messages we send, leading to a threaded loop of interdependent messages. While this “conversational ideal” is easily achieved in face-to-face and computer-mediated communications (CMC), imbuing contingency in human-computer interaction (HCI) is a challenge. We propose two interface features—interaction history and synchronous chat—for increasing perceptions of contingency, and therefore user engagement. We test it with a five-condition, between-participants experiment ( N = 110) on a movie search site. Data suggest that interaction history can indeed heighten perceptions of contingency and dialogue, but is perceived as less interactive than chatting. However, the chat function does not appreciably increase perceived contingency or user engagement, both of which are shown to mediate the effects of message interactivity on attitudes toward the site. Theoretical implications for interactivity research and practical implications for interaction design are discussed.

Computer Interaction

<p>Within human-computer interaction cognitive science is today the leading approach. Yet its position is threaded philosophically as well as from within the field. Most attempts to re-frame human-computer interaction from within the field are minor revisions to the traditional theoretical basis, still without much to say about real-life computer applications. In this paper I shall present and discuss an alternative approach based on activity theory.</p><p>The following summarizes the theoretical anchor points:</p><p>Activity is mediated. That artifacts mediate use means that we are normally not aware of them as such in use, they are transparent to us. Artifacts are seen as historical devices.</p><p>Although collective, each activity is conducted through actions of individuals.</p><p>Activities are not taking place in isolation but interwoven with other activities. Artifacts may be the instruments of a web of activities. The concepts of breakdowns and focus shifts are used in the further analysis of specific computer applications in use, and a mapping technique for such analysis is developed. Based on an example I take the first steps towards a more contex\-tualized analysis of human-computer interaction. The human activity framework has provided a vehicle for bringing together an overall analysis of work and use of computer technology with a detailed analysis of human-computer interaction. It provides a way of understanding the relations between the overall socio-political conditions of work and the specific use of the specific computer application in a specific situation. What actually goes on may be analysed from many different levels of activity, where the actual actors are different, and maybe even different from those who conduct the specific actions.</p>

Computer Interaction

With the continuous development and progress of virtual reality technology in recent years, the application of virtual reality technology in all aspects of real life is no longer limited to the military field, medical, or film production fields, but it gradually appears in front of the public, into the lives of ordinary people. The human-computer interaction method in virtual reality and the presentation effect of the virtual scene are the two most important aspects of the virtual reality experience. How to provide a good human-computer interaction method for virtual reality applications and how to improve the final presentation effect of the virtual reality scene is also becoming an important research direction. This paper takes the virtual fitness club experience system as the application background, analyzes the function and performance requirements of the virtual reality experience system in the virtual reality environment, and proposes the use of Kinect as a video acquisition device to extract the user’s somatosensory operation actions through in-depth information to achieve somatosensory control. This article adopts a real human-computer interaction solution, uses Unity 3D game engine to build a virtual reality scene, defines shaders to improve the rendering effect of the scene, and uses Oculus Rift DK2 to complete an immersive 3D scene demonstration. This process greatly reduces resource consumption; it not only enables users to experience unprecedented immersion as users but also helps people create unprecedented scenes and experiences through virtual imagination. The virtual fitness club experience system probably reduces resource consumption by nearly 70%.

Television drama is an important tool to present hypothetical scenarios and imagine various ways to deal with them, while testing the viability of ethical theories that could guide moral judgements and practical decisions made in real life. Buffy the Vampire Slayer (1997-2003) left an important legacy in Popular Culture captivating viewers worldwide and still being relevant 20 years later. The aim of this article is to revisit Buffy’s Season 4 and analyze it through a libertarian perspective. Over this season, a great number of relevant subjects are discussed, such as the form and function of the state, its relationship with society, the subversion of public authorities and the morality of law and punishment. It is expected that the successful adoption of libertarian ethics and principles to understand this TV show might bring out Libertarianism as a valuable philosophical alternative to be taken into account when looking for solutions to current issues.

The digital humanities (DH) has a long and successful history of creating, using, and maintaining DH centres, as evidenced by the vast centerNet network. Furthermore, some of the most successful centres are constantly evolving in form and function. In this paper, we propose that the next phase in the evolution of the DH centre may involve a related phenomenon from the design research community, called the ‘Living Lab.’ The European Network of Living Labs describes them as dedicated to open forms of design for social good: ‘Living Labs (LLs) are defined as user-centred, open innovation ecosystems based on a systematic user co-creation approach, integrating research and innovation processes in real-life communities and settings.’ Current member labs deal with topics ranging from health and well-being (52%) to mobility (14%), but there are few that focus on issues central to DH, such as open social scholarship. We argue that incorporating more DH into the Living Labs network, and more Living Labs into DH centres, would benefit everyone involved. Specifically, DH labs could benefit from Living Labs’ experience with complex problems, and Living Labs could benefit from DH centres’ experience producing research.

Cyber-attacks are continuing to rise globally. It is therefore vital for organisations to develop the necessary skills to secure their assets and to protect critical national infrastructure. In this short paper, we outline human-computer interaction elements which should be considered when developing a cybersecurity training platform, in an effort to maintain levels of user engagement. We provide an overview of existing training platforms before covering specialist cyber ranges. Aspects of human-computer interaction are explored with regards to their relevance in the context of cyber ranges. We conclude with design suggestions when developing a cyber range platform.

The Relationship

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).
