Pando: Personal Volunteer Computing in Browsers

The large penetration and continued growth in ownership of personal electronic devices represents a freely available and largely untapped source of computing power. To leverage those, we present Pando, a new volunteer computing tool based on a declarative concurrent programming model and implemented using JavaScript, WebRTC, and WebSockets. This tool enables a dynamically varying number of failure-prone personal devices contributed by volunteers to parallelize the application of a function on a stream of values, by using the devices' browsers. We show that Pando can provide throughput improvements compared to a single personal device, on a variety of compute-bound applications including animation rendering and image processing. We also show the flexibility of our approach by deploying Pando on personal devices connected over a local network, on Grid5000, a French-wide computing grid in a virtual private network, and seven PlanetLab nodes distributed in a wide area network over Europe.Comment: 14 pages, 12 figures, 2 table

Role of Artificial Intelligence (AI) art in care of ageing society: focus on dementia

open access articleBackground: Art enhances both physical and mental health wellbeing. The health benefits include reduction in blood pressure, heart rate, pain perception and briefer inpatient stays, as well as improvement of communication skills and self-esteem. In addition to these, people living with dementia benefit from reduction of their noncognitive, behavioural changes, enhancement of their cognitive capacities and being socially active. Methods: The current study represents a narrative general literature review on available studies and knowledge about contribution of Artificial Intelligence (AI) in creative arts. Results: We review AI visual arts technologies, and their potential for use among people with dementia and care, drawing on similar experiences to date from traditional art in dementia care. Conclusion: The virtual reality, installations and the psychedelic properties of the AI created art provide a new venue for more detailed research about its therapeutic use in dementia

Pd and Audio Programming in the 21st Century

In celebration of the 25th anniversary of Pure Data, this essay discusses the development of audio programming up to the present, and considers the role that Pd can continue to play in the computer music of the future

Designing multimodal interactive systems using EyesWeb XMI

This paper introduces the EyesWeb XMI platform (for eXtended Multimodal Interaction) as a tool for fast prototyping of multimodal systems, including interconnection of multiple smart devices, e.g., smartphones. EyesWeb is endowed with a visual programming language enabling users to compose modules into applications. Modules are collected in several libraries and include support of many input devices (e.g., video, audio, motion capture, accelerometers, and physiological sensors), output devices (e.g., video, audio, 2D and 3D graphics), and synchronized multimodal data processing. Specific libraries are devoted to real-time analysis of nonverbal expressive motor and social behavior. The EyesWeb platform encompasses further tools such EyesWeb Mobile supporting the development of customized Graphical User Interfaces for specific classes of users. The paper will review the EyesWeb platform and its components, starting from its historical origins, and with a particular focus on the Human-Computer Interaction aspects

ZenStates: Easy-to-Understand Yet Expressive Specifications for Creative Interactive Environments

International audienceMuch progress has been made on interactive behavior development tools for expert programmers. However, little effort has been made in investigating how these tools support creative communities who typically struggle with technical development. This is the case, for instance, of media artists and composers working with interactive environments. To address this problem, we introduce ZenStates: a new specification model for creative interactive environments that combines Hierarchical Finite-States Machines, expressions, off-the-shelf components called Tasks, and a global communication system called the Blackboard. Our evaluation is three-folded: (a) implementing our model in a direct manipulation-based software interface; (b) probing ZenStates' expressive power through 90 exploratory scenarios; and (c) performing a user study to investigate the understandability of ZenStates' model. Results support ZenStates viability, its expressivity, and suggest that ZenStates is easier to understand-in terms of decision time and decision accuracy-compared to two popular alternatives

Art unlimited: an investigation into contemporary digital arts and the free software movement.

Computing technology has not only significantly shaped many of the contemporary artistic disciplines, it has also given birth to many new and exciting practices. Modest, low cost hardware enabled artists to manipulate real-time multimedia data and coordinate vast amounts of hardware devices, whilst high bandwidth Internet connections has allowed them to communicate and distribute their work rapidly. For this reason, art practices in the digital domain have become highly decentralized. It is therefore not surprising that the rise of free and open source software (FLOSS) has been warmly welcomed and adopted by an increasing number of practitioners. The technical advantages in free software allows them to create works of art with greater freedom and flexibility. Its open and collaborative ideology, on the other hand, further embraces the increasingly autonomous and distributed characteristics in the artistic community. This thesis aims to examine the impact of free and open source software in the context of contemporary digital arts. It will look at the current climate of both digital arts and the FLOSS movement, attempting to rationalize the implications of such a phenomena. It will also provide concrete examples of ongoing activities in FLOSS digital arts, as an evidence and documentation of its development to date. Lastly, the practical work in this research will offer a first hand insight into developing a FLOSS project within the given context

The practices of programming

© 2016 IEEE.How diverse are the ways that programming is done? While a variety of accounts exist, each appears in isolation, neither framed in terms of a distinct practice, nor as one of many such practices. In this work we explore accounts spanning software engineering, bricolage/tinkering, sketching, live coding, code-bending, and hacking. These practices of programming are analyzed in relation to ongoing research, and in particular HCI's 'practice turn', offering connections to accounts of practice in other contexts than programming. The conceptualization of practice helps to interpret recent interest in program code as craft material, and also offers potential to inform programming education, tools and work as well as future research
