Collaborative creativity: The Music Room

In this paper, we reflect on our experience of designing, developing and evaluating interactive spaces for collaborative creativity. In particular, we are interested in designing spaces which allow everybody to compose and play original music. The Music Room is an interactive installation where couples can compose original music by moving in the space. Following the metaphor of love, the music is automatically generated and modulated in terms of pleasantness and intensity, according to the proxemics cues extracted from the visual tracking algorithm. The Music Room was exhibited during the EU Researchers' Night in Trento, Italy

Experimental evaluation of three interaction channels for accessible digital musical instruments

Accessible Digital Musical instruments (ADMIs) dedicated to people with motor disabilities represent a relevant niche in accessibility research. The designer is often required to exploit unconventional physical interaction channels, different from hands and fingers. Although comprehensive evaluation methods for Digital Musical Instruments in general are found in literature, little has been done both in ADMIs evaluation and the analysis of suitable interaction channels from a Human-Computer Interaction perspective. In this work the performance of breath, gaze pointing and head movements is analyzed, in terms of movement speed and stability, through a simple experiment. These interaction channels could be exploited in the design of ADMIs dedicated to quadriplegic musicians. The proposed experiment has similarities with past Fitts Law evaluation tests. Results are discussed proposing possible mappings between channels and musical performance parameters. These results could also be useful to inform the design of different interface types

A Proton-Cyclotron Wave Storm Generated by Unstable Proton Distribution Functions in the Solar Wind

We use audification of 0.092 seconds cadence magnetometer data from the Wind spacecraft to identify waves with amplitudes greater than 0.1 nanoteslas near the ion gyrofrequency (approximately 0.1 hertz) with duration longer than 1 hour during 2008. We present one of the most common types of event for a case study and find it to be a proton-cyclotron wave storm, coinciding with highly radial magnetic field and a suprathermal proton beam close in density to the core distribution itself. Using linear Vlasov analysis, we conclude that the long-duration, large-amplitude waves are generated by the instability of the proton distribution function. The origin of the beam is unknown, but the radial field period is found in the trailing edge of a fast solar wind stream and resembles other events thought to be caused by magnetic field footpoint motion or interchange reconnection between coronal holes and closed field lines in the corona

Free-Improvised Rehearsal-as-Research for Musical HCI

The formal evaluation of new interfaces for musical expression (NIMEs) in their use by ensembles of musicians is a challenging problem in human-computer interaction (HCI). NIMEs are designed to support creative expressions that are often improvised and unexpected. In the collaborative setting of a musical ensemble, interactions are complex and it can be almost impossible to directly evaluate the impact of interface variations. The evaluation environment also needs to be carefully considered. In the wild, concert pressures and practicalities limit experimental control. In the laboratory, studies may not sufficiently reflect real-world usage to make their conclusions relevant. To address some of these issues, we propose a methodology of rehearsal-as-research to study free improvisation by ensembles of NIME performers. In this methodology, evaluation sessions are structured to mirror established practices for improvisation training and performance development. Such sessions can allow controlled, order-balanced studies with extensive data collection in the style of factorial HCI experiments while preserving the artistic setting of a rehearsal. Experiment design, questionnaires, and objective measures such as session duration will be discussed along with two case studies. © Springer Nature Switzerland AG 201

MAMI: A Modular Accessible Musical Instrument

Exploring musicactively can be restricted for someone with cognitive, physical, or sensory impairments. They may face barriers to participation and diminished experiences between their musical expression and the music making means available to them. Technology can be used to bridge these gaps and focus on a person’s capability to create personal instruments that allow for active music making and exploration of sound. Thisdoctoral research aims to look at the use of music technology within the school setting and the needs of the users and those around them.Drawing on this and following an Action Research methodology, a tool will be developed following a participatory design process that utilises both hardware and software, in a modular fashion, to provide a flexible and adaptable system to facilitate music making and sound exploration.The desired outcome will be a toolbox that allows users to put together instruments that suit the needs of those playing them allowing access to musical expression
