“…This paper explored how smart musical instruments could be applied to ubiquitous musical activities. To date, UbiMus activities have mostly involved mobile devices such as smartphones or custom-built devices according to do-it-yourself practices typical of the maker community (Brown, Keller, & de Lima, 2018;Keller et al, 2014;Lazzarini, Keller, & Pimenta, 2015). In this paper, the authors have attempted to provide arguments showing how SMIs can support ubiquitous musical activities.…”

Ubiquitous music (UbiMus) proposes to study how social interaction with mobile and distributed technologies can converge to form novel creativity support tools and music artistic practices. A recent field overlapping with UbiMus is the Internet of Musical Things, which refers to ecosystems of interconnected embedded computers (Musical Things) enabling users to produce, interact with or experience musical content. Musical Things embed electronics, sensors, data forwarding and processing software into physical or virtual objects. Smart musical instruments (SMIs) are an emerging class of Musical Things provided with capabilities of capturing and receiving data supporting instrumental musical practice. Due to their portability and self-containdeness, SMIs enable novel ubiquitous interactions between performers of acoustic and digital musical instruments. After a review of current trends in SMI research, we propose an ubiquitous smart guitar system which uses the guitar as a hub for collaborative music making. We then present a survey conducted with 18 performers to assess the usability, creativity support and engagement with the system. Results show a positive emotional engagement with the system which overall was found easy to use and novel. We also discuss several barriers to creative interaction related to the size of the user interface, creative agency and personalisation.

“…Since the initial experiments in ubiquitous music ( Keller et al, 2011b ; Miletto et al, 2011 ), the browser has been adopted as a prototyping platform of ubimus resources ( Lazzarini et al, 2014 ; Wyse and Subramanian, 2013 ). Despite its multiple drawbacks ( Lazzarini et al, 2015 ), the emergence of the Web Audio Library 4 has provided a common ground for ubimus developments targeting web-based usage. Other relevant initiatives include browser-based deployments of acoustic compilers such as Csound 5 ( Lazzarini et al, 2012 ) and Pure Data (renamed Kiwi) ( Paris et al, 2017 ) and the languages that support multi-platform rendering, such as Faust ( Orlarey et al, 2004 ).…”

We report the results of a study involving twenty subjects doing musical activities in transitional settings, supported by an ecology of tools based on the metaphor for creative action Sound Sphere. The Sound Sphere Ecology (SFS) is a set of web-based tools, loosely organized around audio mixing and processing tasks. It employs verbal strategies for knowledge transfer to provide support for lay participants and specialists. To understand how the stakeholders influence and are influenced by this design strategy, we carried out a series of experiments involving assessments of the participants' behaviours and of the sonic products during various creative musical tasks with SFS. The overall results were positive, indicating that the proposed metaphor provides effective support for casual interaction, highlighting the participants' level of engagement. As a downside, the assessments pointed to ease of use as the lowest and less consistent item among the rated creative factors. We discuss the implications of these results and propose various design enhancements to enable the usage of a larger pool of resources. Considering the heterogeneous profiles of casual stakeholders, methodological refinements are also proposed to assess the knowledge gained by the participants during the exploratory activities, while augmenting their ability to share knowledge. This is one of the first studies on creativity-action metaphors for casual interaction.

“…Com base nas afirmativas, utilizar dispositivos tecnológicos para captação dos movimentos dos olhos, juntamente com o mapeamento da informação para gerar sons, se encaixa no contexto de música ubíqua. Assim, a técnica de eye tracking pode servir de interface para trabalhos de UbiMus, como por exemplo no controle de instrumentos musicais robóticos, apresentados por Camporez et al (2016), e também no comando de interfaces computacionais apresentadas por Lazzarini et al (2014b).…”

O último censo demográfico do Brasil relata que cerca de 13,1 milhões de pessoas se declaram com alguma deficiência do tipo motora. O avanço tecnológico tem contribuído na promoção da acessibilidade e inclusão por meio das técnicas de tecnologia assistiva. Este trabalho apresenta uma interface computacional para controle musical, porém com foco em promover acessibilidade e inclusão a inúmeras pessoas. Por meio do movimento dos olhos o usuário pode controlar uma interface gráfica que envia mensagens (MIDI) para o software Ableton Live com objetivo de controlar a execução sonora. Visando o uso por pessoas leigas no campo musical, a interface proporciona indicações de escolhas para direcionar o usuário a gerar sons mais conexos. As indicações podem ser configuradas de forma manual ou automatizada com auxílio do algoritmo de agrupamento K-means.
