Models and Analysis of Vocal Emissions for Biomedical Applications
The MAVEBA Workshop proceedings, held on a biannual basis, collect the scientific papers presented both as oral and poster contributions, during the conference. The main subjects are: development of theoretical and mechanical models as an aid to the study of main phonatory dysfunctions, as well as the biomedical engineering methods for the analysis of voice signals and images, as a support to clinical diagnosis and classification of vocal pathologies
Silent Light, Luminous Noise: Photophonics, Machines and the Senses
This research takes the basic physical premise that sound can be synthesized using light, explores how this has historically been, and still is achieved, and how it can still be a fertile area for creative, theoretical and critical exploration in sound and the arts. Through the author's own artistic practice, different techniques of generating sound using the sonification of light are explored, and these techniques are then contextualised by their historical and theoretical setting in the time-based arts. Specifically, this text draws together diverse strands of scholarship on experimental sound and film practices, cultural histories, the senses, media theory and engineering to address effects and outcomes specific to photophonic sound and its relation to the moving image, and the sculptural and media works devised to produce it.
The sonifier, or device engendering the transformations discussed is specifically addressed in its many forms, and a model proposed, whereby these devices and systems are an integral, readably inscribed component - both materially and culturally - in both the works they produce, and via our reflexive understanding of the processes involved, of the images or light signals used to produce them. Other practitioners' works are critically engaged to demonstrate how a sense of touch, or the haptic, can be thought of as an emergent property of moving image works which readably and structurally make use of photophonic sound (including the author's), and sound's essential role in this is examined.
In developing, through an integration of theory and practice, a new approach in this under-researched field of sound studies, the author hopes to show how photophonic sound can act as both a metaphorical and material interface between experimental sound and image, and hopefully point the way towards a more comprehensive study of both
Models and Analysis of Vocal Emissions for Biomedical Applications
The International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA) came into being in 1999 from the particularly felt need of sharing know-how, objectives and results between areas that until then seemed quite distinct such as bioengineering, medicine and singing. MAVEBA deals with all aspects concerning the study of the human voice with applications ranging from the newborn to the adult and elderly. Over the years the initial issues have grown and spread also in other fields of research such as occupational voice disorders, neurology, rehabilitation, image and video analysis. MAVEBA takes place every two years in Firenze, Italy. This edition celebrates twenty-two years of uninterrupted and successful research in the field of voice analysis
Distant Electric Vision: Cultural Representations Of Television From “Edison’s Telephonoscope” To The Electronic Screen
Do inventions that exist only on paper have less credibility than functional technologies? How has the meaning and significance of audiovisual media and technology changed over time? This dissertation examines historiography and methodology for media history, arguing for an interdisciplinary approach. It addresses methodological issues in media history—media in transition, media archaeology, and film history—through an examination of television’s speculative era. It tackles moving-image history through an historical investigation of Victorian and Machine age “television”.
Because the concept and terminology of “television” changed dramatically during this period, I use the phrases “distant electric vision” and “seeing by electricity,” to define the concept of electric and electronic moving-image technology. By identifying manifestations of “television” before functional models existed, this dissertation examines the ways in which a modern concept of moving-image technology came into existence. Engineers and inventors, as well as audiences and journalists contributed to the construction of “television.” Newspaper announcements, editorial columns, letters to the editor, rumors and satires circulated.
Victorian-era readers, writers and inventors pictured “seeing by electricity” to do for the eye what the telephone had done for the ear, bringing people closer together though separated
by great distances. In contrast, early twentieth-century Machine-age engineers placed more emphasis on systems, communication, design, and picture quality. Developments in the 1920s with complex systems and electronics made “distant electric vision” a reality.
This dissertation identifies several shifts that took place during television’s speculative era from the Victorian “annihilation of space” to Machine-Age systems engineering. Journalists, readers, and engineers all play a part in the rhetoric of innovation. From the Victorian era to the Machine age, the educational function of popular science and the role of audiences in constructing meaning and value for new technologies remain relatively consistent. I offer several case studies, including Thomas Edison’s inventions, illuminating engineering, and Bell Labs experiments with television. This dissertation argues that modern television design relies on the ability of the technology to make an unnatural experience seem as effortless as possible. Ultimately, it advocates for an expanded definition of media and technology, along with an historical emphasis on context
Walking away from VR as ‘empathy-machine’: peripatetic animations with 360-photogrammetry
My research partakes in an expanded documentary practice that weaves together walking, immersive technologies, and moving image. Two lines of enquiry motivate the research journey: the first responds to the trope of VR as 'empathy-machine' (Milk, 2015), often accompanied by the expression 'walking in someone else's shoes'. Within a research project that begins on foot, the idiom’s significance demands investigation. The second line of enquiry pursues a collaborative artistic practice informed by dialogue and poetry, where the bipedals of walking and the binaries of the digital are entwined by phenomenology, hauntology, performance, and the in-betweens of animation. My practice-as-research methodology involves desk study, experimentation with VR, AR, digital photogrammetry, and CGI animation. Central to my approach is the multifaceted notion of Peripatos ̶ as a school of philosophy, a stroll-like walk, and the path where the stroll takes place ̶ manifested both corporeally and as 'playful curiosity'.
The thread that interweaves practice and theory has my body-moving in the centre; I call it the ‘camera-walk’: a processional shoot that documents a real place and the bodies that make it, while my hand holds high a camera-on-a-stick shooting 360-video. The resulting spherical video feeds into photogrammetric digital processing, and reassembles into digital 3D models that form the starting ground for still images, a site-specific installation, augmented reality (AR) exchanges, and short films. Because 360-video includes the body that carries the camera, the digital meshes produced by the ‘camera-walk’ also reveal the documentarian during the act of documenting. Departing from the pursuit of perfect replicas, my research articulates the iconic lineage of photogrammetry, embracing imperfections as integral.
Despite the planned obsolescence of my digital instruments, I treat my 360-camera as a ‘dangerous tool’, uncovering (and inventing) its hidden virtualities, via Vilém Flusser. Against its formative intentions as an accessory for extreme sports, I focus on everyday life, and become inspired by Harun Farocki’s ‘another kind of empathy’. Within the collaborative projects presented within my thesis, I move away from the colonialist-inspired ideal of ‘walking in someone else’s shoes’, and ‘tread softly’ along the footsteps of my co-walkers
