An interactive audio-visual installation using ubiquitous hardware and web-based software deployment

Abstract

This paper describes an interactive audio-visual musical installation, namely MOTUS, that aims at being deployed using low-cost hardware and software. This was achieved by writing the software as a web application and using only hardware pieces that are built-in most modern personal computers. This scenario implies in specific technical restrictions, which leads to solutions combining both technical and artistic aspects of the installation. The resulting system is versatile and can be freely used from any computer with Internet access. Spontaneous feedback from the audience has shown that the provided experience is interesting and engaging, regardless of the use of minimal hardware.

Audiovisual interactive artwork via web-deployed software: Motus composes Homino-idea

“…This concept aligns with the ideas underlying the MOTUS (TAVARES, 2015), an audiovisual interactive installation that focuses on using affordable hardware for an engine that captures movement and converts it into musical and visual feedback. Cameras have been used in humancomputer interaction for music for decades (WINKLER, 1998), and MOTUS employs this concept while deploying its software as a webpage, thus only requiring hardware that is becoming increasingly ubiquitous (TURNER, 2021) (ZUGARA, 2021).…”

“…This characteristic is found, for example, in computer games, which commonly have physics engines that are unrealistic, yet foster highly engaging and immersive environments PAIVA, 2018). The link between the physical and the virtual worlds, provided by sensors and actuators, has enabled a diversity of interactive artwork, including augmented performances (WINKLER, 1998) (TAVARES et al, 2015), live audience participation (ARAÚJO et al, 2019), augmented musical instruments (TRAIL et al, 2012) (KELLER; GOMES; ALIEL, 2019), instrument development frameworks (CALEGARIO et al, 2019) (FIGUEIRO;SOARES;ROHDE, 2019), and art installations (TAVARES, 2015), (MAMEDES et al, 2011).…”

“…In its original conceptualization, MOTUS was devised with intertwined technical, poetic, and aesthetic ideas. However, musicians using MOTUS raised the demand for ways to change the musical and visual structures behind it, that is, to use MOTUS as a music composition tool (TAVARES, 2015).…”

Detection of methylation, acetylation and glycosylation of protein residues by monitoring 13C chemical-shift changes

“…Data analysis and visualization were performed using Python (van Rossum, 1995), IPython (Perez & Granger, 2007), NumPy (van der Walt et al, 2011), Pandas (McKinney, 2010), Matplotlib (Hunter, 2007), and Seaborn (Waskom et al, 2015); Bayesian computations were carried out with PyMC3 (Salvatier et al, 2016).…”
