PIWeCS: enhancing human/machine agency in an interactive composition system

This paper focuses on the infrastructure and aesthetic approach used in PIWeCS: a Public Space Interactive Web-based Composition System. The concern was to increase the sense of dialogue between human and machine agency in an interactive work by adapting Paine's (2002) notion of a conversational model of interaction as a ‘complex system’. The machine implementation of PIWeCS is achieved through integrating intelligent agent programming with MAX/MSP. Human input is through a web infrastructure. The conversation is initiated and continued by participants through arrangements and composition based on short performed samples of traditional New Zealand Maori instruments. The system allows the extension of a composition through the electroacoustic manipulation of the source material

Implementing Session Centered Calculi

Recently, specific attention has been devoted to the development of service oriented process calculi. Besides the foundational aspects, it is also interesting to have prototype implementations for them in order to assess usability and to minimize the gap between theory and practice. Typically, these implementations are done in Java taking advantage of its mechanisms supporting network applications. However, most of the recurrent features of service oriented applications are re-implemented from scratch. In this paper we show how to implement a service oriented calculus, CaSPiS (Calculus of Services with Pipelines and Sessions) using the Java framework IMC, where recurrent mechanisms for network applications are already provided. By using the session oriented and pattern matching communication mechanisms provided by IMC, it is relatively simple to implement in Java all CaSPiS abstractions and thus to easily write the implementation in Java of a CaSPiS process

H Space: Interactive Augmented Reality Art

open accessThis artwork exploits recent research into augmented reality systems, such as the HoloLens, for building creative interaction in augmented reality. The work is being conducted in the context of interactive art experiences. The first version of the audience experience of the artwork, “H Space”, was informally tested in the SIGGRAPH 2018 Art Gallery context. Experiences with a later, improved, version was evaluated at Tsinghua University. The latest distributed version will be shown in Sydney. The paper describes the concept, the background in both the art and the technological domain and points to some of the key computer human interaction art research issues that the work highlights

Modeling adaptation with a tuple-based coordination language

In recent years, it has been argued that systems and applications, in order to deal with their increasing complexity, should be able to adapt their behavior according to new requirements or environment conditions. In this paper, we present a preliminary investigation aiming at studying how coordination languages and formal methods can contribute to a better understanding, implementation and usage of the mechanisms and techniques for adaptation currently proposed in the literature. Our study relies on the formal coordination language Klaim as a common framework for modeling some adaptation techniques, namely the MAPE-K loop, aspect- and context-oriented programming

Inventing Network Composition: Mobilizing Rhetorical Invention and Social Media for Digital Pedagogy

Inventing Network Composition: Mobilizing Rhetorical Invention and Social Media for Digital Pedagogy investigates how students learn through writing and invention in digital social networks. Pursuing a primary research question of How do student composers invent within networked social media environments?, the dissertation examines how social media and digital writing tools can help students to learn, connect, and share generatively. The core theoretical contribution that this dissertation offers is a theory of network composition, which is a mode of invention that composers engage in social media environments that is intensely social, that is structured by a digital interface, that is interactive and participatory, and that incorporates linguistic, visual, sonic, and other multimodal communication forms. Network composition manifests most notably in network composition pedagogy, which organically locates the work of composing, as well as the disciplinary work of rhetoric and composition, within networked social media environments. This dissertation revisits and updates disciplinary exigencies related to rhetorical invention in digital networks, social media use in the writing classroom, and digital participation as a mode for learning. The dissertation offers an updated approach to invention called network-emergent rhetorical invention that approaches invention as a distributed emergence arising from a network of actants that includes humans, hardware, technologies, interfaces, communities, cultures, software, and infrastructures. It also features an IRB-approved qualitative case study that finds social media to support learning ecology formation, distributed expertise, rhetorical invention, digital and social media literacy development, rhetoric and writing skills formation, and digital citizenship activities. The dissertation additionally examines challenges for social media use in the writing classroom, considering how accessibility, digital aggression, digital discrimination, and data/privacy challenges can and should be navigated. The dissertation closes by speculating about futures for network composition and considering what is at stake for the future of learning, interaction, and participation in digital networks
