New NIME paper: “The ‘Virtualmonium’: an instrument for classical sound diffusion over a virtual loudspeaker orchestra”

The third NIME contribution from the fourMs lab this year was the paper:

The ‘Virtualmonium’: an instrument for classical sound diffusion over a virtual loudspeaker orchestra

Despite increasingly accessible and user-friendly multi-channel compositional tools, many composers still choose stereo formats for their work, where the compositional process is allied to diffusion performance over a ‘classical’ loudspeaker orchestra. Although such orchestras remain common within UK institutions as well as in France, they are in decline in the rest of the world. In contrast, permanent, high-density loudspeaker arrays are on the rise, as is the practical application of 3-D audio technologies. Looking to the future, we need to reconcile the performance of historical and new stereo works, side-byside native 3-D compositions. In anticipation of this growing need, we have designed and tested a prototype ‘Virtualmonium’. The Virtualmonium is an instrument for classical diffusion performance over an acousmonium emulated in higher-order Ambisonics. It allows composers to custom-design loudspeaker orchestra emulations for the performance of their works, rehearse and refine performances off-site, and perform classical repertoire alongside native 3-D formats in the same concert. This paper describes the technical design of the Virtualmonium, assesses the success of the prototype in some preliminary listening tests and concerts, and speculates how the instrument can further composition and performance practice.

New paper: “NIMEhub: Toward a Repository for Sharing and Archiving Instrument Designs”

At NIME we have a large archive of the conference proceedings, but we do not (yet) have a proper repository for instrument designs. For that reason I took part in a workshop on Monday with the aim to lay the groundwork for a new repository:

NIMEhub: Toward a Repository for Sharing and Archiving Instrument Designs [PDF]

This workshop will explore the potential creation of a community database of digital musical instrument (DMI) designs. In other research communities, reproducible research practices are common, including open-source software, open datasets, established evaluation methods and community standards for research practice. NIME could benefit from similar practices, both to share ideas amongst geographically distant researchers and to maintain instrument designs after their first performances. However, the needs of NIME are different from other communities on account of NIME’s reliance on custom hardware designs and the interdependence of technology and arts practice. This half-day workshop will promote a community discussion of the potential benefits and challenges of a DMI repository and plan concrete steps toward its implementation.

New NIME paper: “Trends at NIME – Reflections on Editing ‘A NIME Reader'”

Michael J. Lyons and myself have been working on an edited collection of papers from the NIME conference over the last year, and we presented some reflections on this work at NIME yesterday.

Trends at NIME – Reflections on Editing “A NIME Reader” [PDF]

This paper provides an overview of the process of editing the forthcoming anthology “A NIME Reader—Fifteen years of New Interfaces for Musical Expression.” The selection process is presented, and we reflect on some of the trends we have observed in re-discovering the collection of more than 1200 NIME papers published throughout the 15 yearlong history of the conference. An anthology is necessarily selective, and ours is no exception. As we present in this paper, the aim has been to represent the wide range of artistic, scientific, and technological approaches that characterize the NIME conference. The anthology also includes critical discourse, and through acknowledgment of the strengths and weaknesses of the NIME community, we propose activities that could further diversify and strengthen the field.

Here are slides from the presentation, including a nice word-cloud made from the content of the book.

New paper: Test–retest reliability of computer-based video analysis of general movements in healthy term-born infants

Screenshot from 2015-08-03 22:10:06I have for several years been collaborating with researchers at NTNU in Trondheim on developing video analysis tools for studying the movement patterns of infants. This has resulted in several papers, international testing (and a TV documentary). Now there is a new paper out, with some very successful data testing the reliability of the video analysis method:

Early Human Development 91, no. 10 (October 2015): 555–58. doi:10.1016/j.earlhumdev.2015.07.001.

Highlights:

  • Test–retest reliability of computer-based video analysis of general movements.
  • Results showed high reliability in healthy term-born infants.
  • There was significant association between computer-based video analysis and temporal organization of fidgety movements.

New paper: MuMYO – Evaluating and Exploring the MYO Armband for Musical Interaction

usertest3Yesterday, I presented my microinteraction paper here at the NIME conference (New Interfaces for Musical Expression), organised at Louisiana State University, Baton Rouge, LA. Today I am presenting a poster based on a paper written together with two of my colleagues at UiO.

Title
MuMYO – Evaluating and Exploring the MYO Armband for Musical Interaction

Authors
Kristian Nymoen, Mari Romarheim Haugen, Alexander Refsum Jensenius

Abstract
The MYO armband from Thalmic Labs is a complete and wireless motion and muscle sensing platform. This paper evaluates the armband’s sensors and its potential for NIME applications. This is followed by a presentation of the prototype instrument MuMYO. We conclude that, despite some shortcomings, the armband has potential of becoming a new “standard” controller in the NIME community.
