Exploring 3D gestural interfaces for music creation in video games
In recent years the popularity of music and rhythm-based games has experienced tremendous growth. However almost all of these games require custom hardware to be used as input devices, and these devices control only one or two similar instruments. In this paper we describe One Man Band, a prototype video game for musical expression that uses novel 3D spatial interaction techniques using accelerometer-based motion controllers. One Man Band provides users with 3D gestural interfaces to control both the timing and sound of the music played, with both single and collaborative player modes. We further investigate the ability to detect different musical gestures without explicit selection of mode, giving the user the ability to seamlessly transition between instrument types with a single input device. A formal user study is then presented comparing the musical interface of One Man Band to that of Nintendo\u27s Wii Music. Our results indicate that users generally preferred the interface of One Man Band over that of Wii Music. We also found that users desire to express their own ideas and have explicit control of the melodies created in music-based video games. Copyright 2009 ACM

Enabling Audiovisual User Interfaces
âEnabling Audiovisual User Interfacesâ was a 2-year project, supported by a Marie Curie EU fellowship, conducted at EAVI, Goldsmiths. During the project, I investigated how human-computer interactions can be audiovisualized in order to improve user experience and usability. To address this issue, a new UI paradigm was proposed â AVUI (AudioVisual User Interface). AVUI links interaction, sound and image, building upon the concept of Graphical User Interface (GUI) by adding interconnected sound and image.
The research hypothesis was: the introduction of AVUI, integrating interrelated sonic and visual feedback, reacting to user interactions, would lead to more usable, accessible, playful and engaging UIs, as compared to a traditional GUI â particularly in use cases where accessibility and/or engagement were determinant. I applied AVUIs to case studies, which was the object of user testing. After reaching conclusions from these, I proposed an AVUI framework, including software modules and a set of best practices. Dissemination activities were also implemented
User experience in an interactive music virtual reality system: An exploratory study
The Objects VR interface and study explores interactive music and virtual reality, focusing on user experience, understanding of musical functionality, and interaction issues. Our system offers spatio-temporal music interaction using 3D geometric shapes and their designed relationships. Control is provided by tracking of the hands, and the experience is rendered across a head-mounted display with binaural sound presented over headphones. The evaluation of the system uses a mixed methods approach based on semi-structured interviews, surveys and video-based interaction analysis. On average the system was positively received in terms of interview self-report, metrics for spatial presence and creative support. Interaction analysis and interview thematic analysis also revealed instances of frustration with interaction and levels of confusion with system functionality. Our results allow reflection on design criteria and discussion of implications for facilitating music engagement in virtual reality. Finally our work discusses the effectiveness of measures with respect to future evaluation of novel interactive music systems in virtual reality
Design Strategies for Adaptive Social Composition: Collaborative Sound Environments
In order to develop successful collaborative music systems a variety
of subtle interactions need to be identified and integrated. Gesture
capture, motion tracking, real-time synthesis, environmental
parameters and ubiquitous technologies can each be effectively used
for developing innovative approaches to instrument design, sound
installations, interactive music and generative systems. Current
solutions tend to prioritise one or more of these approaches, refining
a particular interface technology, software design or compositional
approach developed for a specific composition, performer or
installation environment. Within this diverse field a group of novel
controllers, described as âTangible Interfacesâ have been developed.
These are intended for use by novices and in many cases follow a
simple model of interaction controlling synthesis parameters through
simple user actions. Other approaches offer sophisticated
compositional frameworks, but many of these are idiosyncratic and
highly personalised. As such they are difficult to engage with and
ineffective for groups of novices. The objective of this research is to
develop effective design strategies for implementing collaborative
sound environments using key terms and vocabulary drawn from the
available literature. This is articulated by combining an empathic
design process with controlled sound perception and interaction
experiments. The identified design strategies have been applied to
the development of a new collaborative digital instrument. A range
of technical and compositional approaches was considered to define
this process, which can be described as Adaptive Social Composition.

Moving sounds and sonic moves : exploring interaction quality of embodied music mediation technologies through a user-centered perspective
This research project deals with the user-experience related to embodied music mediation technologies. More specifically, adoption and policy problems surrounding new media (art) are considered, which arise from the usability issues that to date pervade new interfaces for musical expression. Since the emergence of new wireless mediators and control devices for musical expression, there is an explicit aspiration of the creative industries and various research centers to embed such technologies into different areas of the cultural industries. The number of applications and their uses have exponentially increased over the last decade. Conversely, many of the applications to date still suffer from severe usability problems, which not only hinder the adoption by the cultural sector, but also make culture participants take a rather cautious, hesitant, or even downright negative stance towards these technologies. Therefore, this thesis takes a vantage point that is in part sociological in nature, yet has a link to cultural studies as well. It combines this with a musicological frame of reference to which it introduces empirical user-oriented approaches, predominantly taken from the field of human-computer-interaction studies. This interdisciplinary strategy is adopted to cope with the complex nature of digital embodied music controlling technologies.
Within the Flanders cultural (and creative) industries, opportunities of systems affiliated with embodied interaction are created and examined. This constitutes an epistemological jigsaw that looks into 1) âwhich stakeholders require what various levels of involvement, what interactive means and what artistic possibilities?â, 2) âthe way in which artistic aspirations, cultural prerequisites and operational necessities of (prospective) users can be defined?â, 3) âhow functional, artistic and aesthetic requirements can be accommodated?â, and 4) âhow quality of use and quality of experience can be achieved, quantified, evaluated and, eventually, improved?â. Within this multi-facetted problem, the eventual aim is to assess the applicability of the foresaid technology, both from a theoretically and empirically sound basis, and to facilitate widening and enhancing the adoption of said technologies.
Methodologically, this is achieved by 1) applied experimentation, 2) interview techniques, 3) self-reporting and survey research, 4) usability evaluation of existing devices, and 5) human-computer interaction methods applied â and attuned â to the specific case of embodied music mediation technologies. Within that scope, concepts related to usability, flow, presence, goal assessment and game enjoyment are scrutinized and applied, and both task- and experience-oriented heuristics and metrics are developed and tested.
In the first part, covering three chapters, the general context of the thesis is given. In the first chapter, an introduction to the topic is offered and the current problems are enumerated. In the second chapter, a broader theoretical background is presented of the concepts that underpin the project, namely 1) the paradigm of embodiment and its connection to musicology, 2) a state of the arts concerning new interfaces for musical expression, 3) an introduction into HCI-usability and its application domain in systematic musicology, 4) an insight into user-centered digital design procedures, and 5) the challenges brought about by e-culture and digitization for the cultural-creative industries. In the third chapter, the state of the arts concerning the available methodologies related to the thesisâ endeavor is discussed, a set of literature-based design guidelines are enumerated and from this a conceptual model is deduced which is gradually presented throughout the thesis, and fully deployed in the âSoundFieldâ-project (as described in Chapter 9).
The following chapters, contained in the second part of the thesis, give a quasi-chronological overview of how methodological concepts have been applied throughout the empirical case studies, aimed specifically at the exploration of the various aspects of the complex status quaestionis. In the fourth chapter, a series of application-based tests, predominantly revolving around interface evaluation, illustrate the complex relation between gestural interfaces and meaningful musical expression, advocating a more user-centered development approach to be adopted. In the fifth chapter, a multi-purpose questionnaire dubbed âWhat Moves Youâ is discussed, which aimed at creating a survey of the (prospective) end-users of embodied music mediation technologies. Therefore, it primarily focused on cultural background, musical profile and preferences, views on embodied interaction, literacy of and attitudes towards new technology and participation in digital culture. In the sixth chapter, the ethnographical studies that accompanied the exhibition of two interactive art pieces, entitled "Heart as an Ocean" & "Lament", are discussed. In these studies, the use of interview and questionnaire methodologies together with the presentation and reception of interactive art pieces, are probed. In the seventh chapter, the development of the collaboratively controlled music-game âSync-In-Teamâ is presented, in which interface evaluation, presence, game enjoyment and goal assessment are the pivotal topics. In the eighth chapter, two usability studies are considered, that were conducted on prototype systems/interfaces, namely a heuristic evaluation of the âVirtual Stringâ and a usability metrics evaluation on the âMulti-Level Sonification Toolâ. The findings of these two studies in conjunction with the exploratory studies performed in association with the interactive art pieces, finally gave rise to the âSoundFieldâ-project, which is recounted in full throughout the ninth chapter. The integrated participatory design and evaluation method, presented in the conceptual model is fully applied over the course of the âSoundFieldâ-project, in which technological opportunities and ecological validity and applicability are investigated through user-informed development of numerous use cases.
The third and last part of the thesis renders the final conclusions of this research project. The tenth chapter sets out with an epilogue in which a brief overview is given on how the state of the arts has evolved since the end of the project (as the research ended in 2012, but the research field has obviously moved on), and attempts to consolidate the implications of the research studies with some of the realities of the Flemish cultural-creative industries. Chapter eleven continues by discussing the strengths and weaknesses of the conceptual model throughout the various stages of the project. Also, it comprises the evaluation of the hypotheses, how the assumptions that were made held up, and how the research questions eventually could be assessed. Finally, the twelfth and last chapter concludes with the most important findings of the project. Also, it discusses some of the implications on cultural production, artistic research policy and offers an outlook on future research beyond the scope of the âSoundFieldâ project
The Smart Stage: Designing 3D interaction metaphors for immersive and ubiquitous music systems
This conceptual paper describes a work in
progress in the process of design and implementation of the
Smart Stage, an interactive music system prototype for
collaborative musical creativity in immersive and ubiquitous
environments. This system is intended to have a low entry
barrier, thus more forgiving to users with lesser experience or
knowledge in music, and it is designed with affordances to
support intuitive progress in improvisational performance in a
collaborative setting. We present a preliminary technical
overview of the system and a first case study of a 3D
interaction metaphor for granular synthesis, developed for this
environment.Innovation Agency (AgĂȘncia de Inovação, ADI, Portugal) and Quadro de ReferĂȘncia EstratĂ©gico Nacional
