Computer Musicking: Designing for Collaborative Digital Musical Interaction.

PhDThis thesis is about the design of software which enables groups of people to make music together. Networked musical interaction has been an important aspect of Sound and Music Computing research since the early days, although collaborative music software has yet to gain mainstream popularity, and there is currently limited research on the design of such interfaces. This thesis draws on research from Computer Supported Cooperative Work (CSCW) to explore the design of systems for Collaborative Digital Musical Interaction (CDMI). A central focus of this research is the concept of Awareness: a person’s understanding of what is happening, and of who is doing what. A novel software interface is developed and used over three experimental studies to investigate the effects different interface designs have on the way groups of musicians collaborate. Existing frameworks from CSCW are extended to accommodate the properties of music as an auditory medium, and theories of conventional musical interaction are used to elaborate on the nature of music making as a collaborative and social activity which is focused on process-oriented creativity. This research contributes to the fields of Human-Computer Interaction (HCI), Computer Supported Cooperative Work, and Sound and Music Computing through the identification of empirically derived design implications and recommendations for collaborative musical environments. These guidelines are demonstrated through the design of a hypothetical collaborative music system. This thesis also contributes towards the methodology for evaluating such systems, and considers the distinctions between CDMI and the forms of collaboration traditionally studied within CSCW.Engineering and Physical Sciences Research Council (EPSRC) Doctoral Training Account Award (DTA)

Wii like to play too : computer gaming habits of older adults

This thesis introduces the innovative idea of the use of computer games and interactive entertainment by second-and third-age adults, specifically in the area of game content and interaction. This form of entertainment and technologies has become varied recently, with increased and widening participation of groups such as older adults of differing ages. The purposes of using technology involve well-being, intergenerational relationships and learning; these are some aspects primarily associated with the study of gerontology and game studies. This investigation encompassed two phases. Phase One examined the type of computer games older adults would like to play relating to hobbies, dreams and interests. Qualitative and quantitative data was collected in a step-by-step approach enabling participants to design their own game idea in an informal, jargon-free environment allowing for ease of understanding and coherence. Phase Two of the investigation involved older adults playing one of two consoles (Wii and PS-2). The games chosen were from the sports genre (golf, tennis and boxing) and were required to play for 15 minutes each. Results from Phase One indicated that participants were able to devise and design a number of game genres, and having prior knowledge of gaming did not necessarily aid when trying to design a game concept. Results from Phase Two indicated participants’ playing on the Wii was easier due to the nature of the console pad, rather than the traditional game pad used on the PS-2. Qualitative and quantitative data analysis interaction mechanism was far more influential on participants’ experience of flow than content. Extensive technological developments have enabled audiences in recent years to interact with gaming platforms easier than before, using motion sensor and natural body movement during game play. Preliminary design guidelines established from this investigation stipulate a multitude of aspects relating to interaction and content to enhance the experience of gaming for older adults.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Haute games : innovative self and self-identity blendings

This thesis introduces the original idea that it is possible, and productive, to consider the ‘blending’ of (or deliberate creative combining of methods from) the fields of fine art practice and science practice, using selected empirical research methods to investigate constructions of self and self-identity that emerge between disciplines. In particular, the thesis investigates how the scientific aspects of modern computer games, for instance, can be seen to affect emotional responses from viewers and how those responses are, in turn, affected by the ‘blending’ of aesthetic concerns with consideration of alternative cognitive processes that induce relaxation to connect with participant-players’ self-identities. This process created a method to access cognitive processes, hitherto unexplored by computer-game developers. This research locates its arguments primarily in and between the disciplines, Art and Game Studies and supports the findings with examples taken from art practice and with theories of Psychology and Gaming. This thesis documents the creation of the author’s original hybrid ‘art- work-game’, known as ‘Star World’. It describes the process of ‘Star World’s’ creation, with analysis of the efficacy of this environment as a space where the mapping of narrative, and where perceptual and interactive ‘blendings’ of self and self-identity were employed and tested, with both qualitative and empirical studies of the experiences and perceptions of participant-players. The research focuses on how the distinctive abstract environment, ‘Star World’, affords and facilitates personal expression and interaction for computer-game players. It reveals specific cognitive processes undergone by participant-players; evidence that supports and validates the conjecture that participant-players use personal frames of reference when navigating, exploring and interpreting computer games. Teach-back protocols and their impact are shown to improve the interactivity and immersive potential of the environment. Overall, this thesis classifies ‘haute game’ rules that are formulated to identify virtual environments creating unique, alternative ‘blendings’ with participant-players and assembles a framework for developers to pursue, when producing original computer-game genres. It offers an innovative case study of value to future scholars of Game Studies, as well as to game developers, with cautionary examples provided to assist in dealing with situations where emotional states are accessed by game play. This thesis highlights the potential of interactive art and game design to produce beneficial outcomes for its participant-players, moreover, it demonstrates, with empirical evidence, the effect of the virtual environment on its participant-players.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Subjective-situational Study of Presence

The paper is devoted to the description of the interview approach to reveal presence state and its types such as environmental, social and personal presence. The questions of the interview is described and analyzed in detail. The questions were formulated in view of the subject's behavior and the reactions during tests. Also the answers of the test subjects are analyzed from a perspective of sense of presence revealing. The interview method proved its efficiency. This method allowed to identify in practice types of presence being under researching. In addition, it has enabled a better understanding of the dynamics of the perception changes in the case of presence. The flexibility of this method allows to adjust it under specific virtual environment, and to clarify all key aspects to understand presence. © 2014 Springer International Publishing

User-centered virtual environment design for virtual rehabilitation

<p>Abstract</p> <p>Background</p> <p>As physical and cognitive rehabilitation protocols utilizing virtual environments transition from single applications to comprehensive rehabilitation programs there is a need for a new design cycle methodology. Current human-computer interaction designs focus on usability without benchmarking technology within a user-in-the-loop design cycle. The field of virtual rehabilitation is unique in that determining the efficacy of this genre of computer-aided therapies requires prior knowledge of technology issues that may confound patient outcome measures. Benchmarking the technology (e.g., displays or data gloves) using healthy controls may provide a means of characterizing the "normal" performance range of the virtual rehabilitation system. This standard not only allows therapists to select appropriate technology for use with their patient populations, it also allows them to account for technology limitations when assessing treatment efficacy.</p> <p>Methods</p> <p>An overview of the proposed user-centered design cycle is given. Comparisons of two optical see-through head-worn displays provide an example of benchmarking techniques. Benchmarks were obtained using a novel vision test capable of measuring a user's stereoacuity while wearing different types of head-worn displays. Results from healthy participants who performed both virtual and real-world versions of the stereoacuity test are discussed with respect to virtual rehabilitation design.</p> <p>Results</p> <p>The user-centered design cycle argues for benchmarking to precede virtual environment construction, especially for therapeutic applications. Results from real-world testing illustrate the general limitations in stereoacuity attained when viewing content using a head-worn display. Further, the stereoacuity vision benchmark test highlights differences in user performance when utilizing a similar style of head-worn display. These results support the need for including benchmarks as a means of better understanding user outcomes, especially for patient populations.</p> <p>Conclusions</p> <p>The stereoacuity testing confirms that without benchmarking in the design cycle poor user performance could be misconstrued as resulting from the participant's injury state. Thus, a user-centered design cycle that includes benchmarking for the different sensory modalities is recommended for accurate interpretation of the efficacy of the virtual environment based rehabilitation programs.</p

Revisiting the Twentieth Century Through the Lens of Generation X and Digital Games: A Scoping Review

Video games have been around since the 1960s and have impacted upon society in a myriad of different ways. The purpose of this scoping review is to identify existing literature within the domain of video games which recruited participants from the Generation X (1965–1980) cohort. Six databases were searched (ACM, CINHAL Google Scholar, PubMed, Scopus, and Web of Science) focusing on published journal papers between 1970 and 2000. Search results identified 3186 articles guided by the PRISMA Extension for Scoping Reviews (PRISMA-ScR); 4 papers were irretrievable, 138 duplicated papers were removed, leaving 3048 were assessed for eligibility and 3026 were excluded. Articles (n = 22) were included into this review, with four papers primarily published in 1997 and in 1999. Thematic analysis identified five primary themes: purpose and objectives, respective authors’ reporting, technology, ethics and environment) and seven secondary themes: populations, type of participants (e.g. children, students), ethical approval, study design, reimbursement, language, type of assessments. This scoping review is distinctive because it primarily focuses on Generation X, who have experienced and grown-up with videogames, and contributes to several disciplines including: game studies, gerontology and health, and has wider implications from a societal, design and development perspective of video games

Towards a Design Methodology for Virtual Environments

Virtual Reality (VR) is currently the subject of much academic research and virtual environments, particularly in the form of 3D computer games, are the subject of much commercial activity. However, the development process for VEs is not well documented or fully researched. In this paper the available literature relating to VE design is briefly reviewed prior to the presentation of a possible design methodology for VEs. The paper then goes on to discuss the weak points in the methodology and problems with inter-relating the various stages. Finally, future areas of research are identified
