Description
The importance of interactive electronic devices in the twenty-first century is a quickly expanding one, and the field of music technology is not exempt from this. Most traditional acoustic instruments pose challenges for individuals lacking fine motor skills, coordination, or grip strength. The author has responded to this issue as they experience it by developing a programmable interactive instrument system using a Mugic Motion System hardware, which includes a gyroscopic sensor, and Max/MSP, a visual programming environment which allows for customizable musical engagement for a variety of user types and requirements. This thesis explores the potential of interactive electronic devices to revolutionize the field of music as well as their potential in larger immersive environments, allowing creativity to reach a wider range of people regardless of physical limitations. The use of interactive sensor devices presents a not yet completely explored path for creating forms of sonic and multimedia interaction to a degree that has not yet become standard within either the musical field nor the emerging field of immersive environments and storytelling. The implications of a more fleshed out sensor-based system extend beyond the sound potential explored within this paper, and could allow interaction with visual aspects and motion based interactive art installations. This technology can also be applied as part of larger interactive systems, such as those found in theme parks and other large interactive attraction spaces. The author offers a novel approach to the democratization of music by leveraging the potential of interactive electronic devices for a population traditionally overlooked in music.

Description
The genre of world music and its market’s reliance on musical exoticism, othering, and the audience’s insatiable quest for musical authenticity have influenced and shaped the way artists construct and negotiate their musical representation. With the popularization of democratized music platforms such as Bandcamp, artists have greater autonomy in terms of artistic representation and musical distribution in the online world. Although the internet has in some ways disrupted the old power structures of the music industry, the old forms of world music marketing have been reinscribed into a new context. Old stereotypes and narratives of authenticity in world music have permeated the digital representation of artists and their music. Music recommendation algorithms also shape the way artists are represented in digital environments. Semantic descriptors such as social tags play a vital role in musical identification and recommendation systems implemented by streaming platforms. The use of social tags such as #worldmusic homogenizes diverse cultural sounds into a single umbrella genre. #World music also creates avenues for old stereotypes and narratives of authenticity to re-emerge. This re-emergence of the old tropes of world music creates less equitable recommendation and representational outcomes for musicians operating within the genre. In the age of streaming, where does world music belong? How do artists negotiate representation online? This thesis explores the dynamics of representation and the projections of “authenticity” between world music artists and record labels inside of Bandcamp’s digital ecosystem. By juxtaposing the traditional framework of “world music” marketing with new and evolving methods of distribution and artistic representation, it is possible to see how digital media are reshaping but also reproducing some of the old paradigms of world music. I also propose that a new framework needs to be established to study the impact digital streaming has on the genre of world music. This new framework, which I call “World Music 3.0,” will encompass how algorithms, tech companies, and the democratization of musical practices interact within a globalized community.

Description
This dissertation is an account of the strategies that I employed in the compositionof three of my recent pieces: Situación #3, for flute (bass flute), clarinet (bass clarinet), piano, percussion, violin, cello, and electronics; Situación #2, for amplified acoustic guitar and two performers; and Between transparency and the invisible, for orchestra and electronics.
The first chapter, devoted to Situación #3 discusses the re-interpretation of memories and visual records with musical means. The second chapter focuses on Situación #2 and the issues of physicality and collaboration that originated the piece. The third chapter addresses Between transparency and the invisible and how it was informed by my experience contemplating visual art.

Description
This project explores the potential for the accurate prediction of basketball shooting posture with machine learning (ML) prediction algorithms, using the data collected by an Internet of Things (IoT) based motion capture system. Specifically, this question is addressed in the research - Can I develop an ML model to generalize a decent basketball shot pattern? - by introducing a supervised learning paradigm, where the ML method takes acceleration attributes to predict the basketball shot efficiency. The solution presented in this study considers motion capture devices configuration on the right upper limb with a sole motion sensor made by BNO080 and ESP32 attached on the right wrist, right forearm, and right shoulder, respectively, By observing the rate of speed changing in the shooting movement and comparing their performance, ML models that apply K-Nearest Neighbor, and Decision Tree algorithm, conclude the best range of acceleration that different spots on the arm should implement.

Description
Several music players have evolved in multi-dimensional and surround sound systems. The audio players are implemented as software applications for different audio hardware systems. Digital formats and wireless networks allow for audio content to be readily accessible on smart networked devices. Therefore, different audio output platforms ranging from multispeaker high-end surround systems to single unit Bluetooth speakers have been developed. A large body of research has been carried out in audio processing, beamforming, sound fields etc. and new formats are developed to create realistic audio experiences.
An emerging trend is seen towards high definition AV systems, virtual reality gears as well as gaming applications with multidimensional audio. Next generation media technology is concentrating around Virtual reality experience and devices. It has applications not only in gaming but all other fields including medical, entertainment, engineering, and education. All such systems also require realistic audio corresponding with the visuals.
In the project presented in this thesis, a new portable audio hardware system is designed and developed along with a dedicated mobile android application to render immersive surround sound experiences with real-time audio effects. The tablet and mobile phone allow the user to control or “play” with sound directionality and implement various audio effects including sound rotation, spatialization, and other immersive experiences. The thesis describes the hardware and software design, provides the theory of the sound effects, and presents demonstrations of the sound application that was created.

Description
The increased risk of falling and the worse ability to perform other daily physical activities in the elderly cause concern about monitoring and correcting basic everyday movement. In this thesis, a Kinect-based system was designed to assess one of the most important factors in balance control of human body when doing Sit-to-Stand (STS) movement: the postural symmetry in mediolateral direction. A symmetry score, calculated by the data obtained from a Kinect RGB-D camera, was proposed to reflect the mediolateral postural symmetry degree and was used to drive a real-time audio feedback designed in MAX/MSP to help users adjust themselves to perform their movement in a more symmetrical way during STS. The symmetry score was verified by calculating the Spearman correlation coefficient with the data obtained from Inertial Measurement Unit (IMU) sensor and got an average value at 0.732. Five healthy adults, four males and one female, with normal balance abilities and with no musculoskeletal disorders, were selected to participate in the experiment and the results showed that the low-cost Kinect-based system has the potential to train users to perform a more symmetrical movement in mediolateral direction during STS movement.

Description
I am interested in performance that includes multiple artistic media. I am looking for a way to communicate with other artists that can clearly express the meaning of an artistic gesture that they can interpret for their medium. I wish to make transmedia performance art with a meaning that is clear to an audience. That meaning can be abstract. Sometimes we call art "abstract" to imply that it has no perceivable meaning. However, everything has meaning. Even if a piece of art does not have narrative meaning, we can still perceive a structure. That is thanks to our imagination. Imagination is our way of making sense of our experience. I believe that if I can identify some of the imaginative structures through which I perceive and understand my own work, I can use those structures to annotate or organize scores for improvised performance pieces. I am interested in how we understand art. One theory of understanding, which comes from Mark Johnson, involves "image schemata." Image schemata (sing. schema) are basic, abstract structures that we develop based on what we perceive from our physical interactions with the environment. We project these structures that come from a physical domain onto the mental domain. Johnson calls this process "metaphorical projection," and he calls our ability to do this "imagination." By metaphorically projecting image schemata from one domain to another, we form meaning of our experiences, and thus contribute to our understanding of the world. I believe that I can use image schemata to explain the meanings inherent in the art I make and to explain the connections in meaning between one artistic medium to another. I wish to apply this in a transmedia performance setting. First, I will analyze previous transmedia works in terms of image schemata. Second, I will make a score using image schemata for an improvised performance. Third, I will reflect on the results of attempting to rehearse that score.

Description
Beneath the epidermis, the human body contains a vibrant and complex ecology of interwoven rhythms such the heartbeat, the breath, the division of cells, and complex brain activity. By repurposing emergent medical technology into real-time gestural sound controllers of electronic musical instruments, experimental musicians in the 1960s and 1970s – including David Rosenboom – began to realize the expressive potential of these biological sounds. Composers experimented with breath and heartbeat. They also used electroencephalography (EEG) sensors, which register various types of brain waves. Instead of using the sound of brain waves in fixed-media pieces, many composers took diverse approaches to the challenge of presenting this in live performance. Their performance practices suggest different notions of embodiment, a relationship in this music which has not been discussed in detail.
Rosenboom reflects extensively on this performance practice. He supports his EEG research with theory about the practice of biofeedback. Rosenboom’s work with EEG sensors spans several decades and continue today, which has allowed him to make use of advancing sensing and computing technologies. For instance, in his 1976 On Being Invisible, the culmination of his work with EEG, he makes use of analyzed EEG data to drive a co-improvising musical system.
In this thesis, I parse different notions of embodiment in the performance of EEG music. Through a critical analysis of examples from the discourse surrounding EEG music in its early years, I show that cultural perception of EEG sonification points to imaginative speculations about the practice’s potentials; these fantasies have fascinating ramifications on the role of the body in this music’s performance. Juxtaposing these with Rosenboom, I contend that he cultivated an embodied performance practice of the EEG. To show how this might be manifest in performance, I consider two recordings of On Being Invisible.
As few musicologists have investigated this particular strain of musical experimentalism, I hope to contextualize biofeedback musicianship by offering an embodied reading of this milestone work for EEG.

Description
Although tremor, rigidity, and bradykinesia are cardinal symptoms of Parkinson's disease (PD), impairments of gait and balance significantly affect quality of life, especially as the disease progresses, and do not respond well to anti-parkinsonism medications. Many studies have shown that people with PD can walk better when appropriate cues are presented but, to the best of our knowledge, the effects of real-time feedback of step length and uprightness of posture on gait and posture have not been specifically investigated. If it can be demonstrated that real-time feedback can improve posture and gait, the resultant knowledge could be used to design effective rehabilitation strategies to improve quality of life in this population.
In this feasibility study, we have developed a treadmill-based experimental paradigm to provide feedback of step length and upright posture in real-time. Ten subjects (mean age 65.9 ± 7.6 years) with mild to moderate PD (Hoehn and Yahr stage III or below) were evaluated in their ability to successfully utilize real-time feedback presented during quiet standing and treadmill walking tasks during a single data collection session in their medication-on state. During quiet standing tasks in which back angle feedback was provided, subjects were asked to utilize the feedback to maintain upright posture. During treadmill walking tasks, subjects walked at their self-selected speed for five minutes without feedback, with feedback of back angle, or with feedback of step length. During walking tasks with back angle feedback, subjects were asked to utilize the feedback to maintain upright posture. During walking tasks with step length feedback, subjects were asked to utilize the feedback to walk with increased step length. During quiet standing tasks, measurements of back angle were obtained; during walking tasks, measurements of back angle, step length, and step time were obtained.
Subjects stood and walked with significantly increased upright posture during the tasks with real-time back angle feedback compared to tasks without feedback. Similarly, subjects walked with significantly increased step length during tasks with real-time step length feedback compared to tasks without feedback. These results demonstrate that people with PD can utilize real-time feedback to improve upright posture and gait.
