INTRODUCTION: We propose AudioVisual User Interfaces (AVUI), a novel type of UI linking interaction, sound and image. It extends the concept of Graphical User Interface (GUI) by adding interconnected sound and image. OBJECTIVES: We aim to situate AVUIs in relation to identified relevant fields: Human-Computer Interaction (HCI), sonic interaction de...
Chapter
This chapter explores three systems for mapping embodied gesture, acquired with electromyography and motion sensing, to sound synthesis. A pilot study using granular synthesis is presented, followed by studies employing corpus-based concatenative synthesis, where small sound units are organized by derived timbral features. We use interactive machin...

This chapter presents an overview of Interactive Machine Learning (IML) techniques applied to the analysis and design of musical gestures. We go through the main challenges and needs related to capturing, analysing, and applying IML techniques to human bodily gestures with the purpose of performing with sound synthesis systems. We discuss how diffe...

Musical performance can be thought of in multimodal terms – physical interaction with musical instruments produces sound output, often while the performer is visually reading a score. Digital Musical Instrument (DMI) design merges tenets of HCI and musical instrument practice. Audiovisual performance and other forms of multimedia might benefit from...

This article explores how computation opens up possibilities for new musical practices to emerge through technology design. Using the notion of the cultural probe as a lens, we consider the digital musical instrument as an experimental device that yields findings across the fields of music, sociology, and acoustics. As part of an artistic-research...

This paper presents a method for mapping embodied gesture , acquired with electromyography and motion sensing, to a corpus of small sound units, organised by derived timbral features using concatenative synthesis. Gestures and sounds can be associated directly using individual units and static poses, or by using a sound tracing method that leverage...

In this paper, we describe the definition of the body being extended by the concepts of other disciplines, such as philosophy, where some define it as decided by the potential of its actions. Inspired by these philosophical ideas of the body, a dance performance, Skin-awareness, was developed to explore and experiment with the body as a self-aware...

The term 'spatial presence' refers to the feeling of presence in a mediated space. This subjective experience has been discussed in media theory, sound art, film and performance. It depends on multiple variables, or parameters. This paper presents a parametric model that can be used to analyze those variables and their relationships. It exposes met...

There is an identified lack of visual feedback in electronic music performances. Live visuals have been used to fill in this gap. However, there is a scarcity of studies that analyze the effectiveness of live visuals in conveying feedback. In this paper, we aim to study the contribution of live visuals to the understanding of electronic music perfo...

The combined use of sound and image has a rich history, from audiovisual artworks to research exploring the potential of data visualization and sonification. However, we lack standard tools or guidelines for audiovisual (AV) interaction design, particularly for live performance. We propose the AVUI (AudioVisual User Interface), where sound and imag...
Conference Paper
Movement design is typically based on evoking shapes in space. In interactive systems, user movement is often dictated by the system's sensing capabilities. In neither of these cases are the differences across individual users or expressive variations they make accommodated. We present an exploratory study that uses Laban Movement Analysis as a fra...

Machine learning is one of the most important and successful techniques in contemporary computer science. It involves the statistical inference of models (such as classifiers) from data. It is often conceived in a very impersonal way, with algorithms working autonomously on passively collected data. However, this viewpoint hides considerable human...

Sonic interaction is the continuous relationship between user actions and sound, mediated by some technology. Because interaction with sound may be task oriented or experience-based it is important to understand the nature of action-sound relationships in order to design rich sonic interactions. We propose a participatory approach to sonic interact...

Expressivity is a visceral capacity of the human body. To understand what makes a gesture expressive, we need to consider not only its spatial placement and orientation, but also its dynamics and the mechanisms enacting them. We start by defining gesture and gesture expressivity, and then present fundamental aspects of muscle activity and ways to c...

This article draws a perceptual approach to audio-visual mapping. Clearly perceivable cause and effect relationships can be problematic if one desires the audience to experience the music. Indeed perception would bias those sonic qualities that fit previous concepts of causation, subordinating other sonic qualities, which may form the relations bet...

With the advent of interactive digital media, people are no longer simply 'users'. They actively shift between various roles: author, collaborator, and even performer.

Analog audio needs a separate physical circuit for each channel. Each microphone in a studio or on a stage, for example, must have its own circuit back to the mixer. Routing of the signals is inflexible. Digital audio is frequently wired in a similar way to analog. Although several channels can share a single physical circuit (e.g., up to 64 with A...
