This study examined racial and athletic identity among African American football players at historically Black colleges universities (HBCUs) predominantly White institutions (PWIs). Negotiating the dualism of identities can be problematic because both roles are subject to prejudice discrimination, particularly for student-athletes in revenue-producing sports like football. Results indicated that seniors institution types reported significantly lower levels Public Regard predicted higher...

When vibrations are synchronized with our actions, we experience them as material properties. This has been used to create virtual experiences like friction, counter-force, compliance, or torsion. Implementing such is non-trivial, requiring high temporal resolution in sensing, fidelity tactile output, and low latency. To make this style of haptic feedback more accessible non-domain experts, present Haptic Servos: self-contained rendering devices which encapsulate all timing-critical...

Augmented Footwear has become an increasingly common research area. However, as this is a comparatively new direction in HCI, researchers and designers are not able to build upon platforms. We discuss the design space of shoes for augmented tactile reality, focussing on physiological biomechanical factors well technical considerations. present open source example implementation from space, intended experimental platform vibrotactile rendering AR provide details experiences that could be...

With most digital devices, vibrotactile feedback consists of rhythmic patterns continuous vibration. In contrast, when interacting with physical objects, we experience many their material properties through vibration which is not continuous, but dynamically coupled to our actions. We assume the first style lead hermeneutic mediation, while second leads embodied mediation. What if both types mediation could be used design tactile symbols? To investigate this, five haptic experts designed...

An implicit assumption in metaphor use is that it requires grounding a familiar concept, prominently seen the popular Desktop Metaphor. In human-to-human communication, however, abstract metaphors, without such grounding, are often used with great success. To understand when and why metaphors work, we present case study of voice teaching. Voice educators must teach about subjective, sensory experiences rely on to express information unseen intangible processes inside body. We thematic...

RaveNET connects people to music, enabling musicians modulate sound using signals produced by their own bodies or the of others. We present three wearable prototype nodes in an inaugural performance: Bones, anti-corset, uses capacitive sensing detect stretch as singer breathes. Tendons, a half-glove, measures galvanic skin response, pulse, and movement bass player's hands. Veins, cap with electrodes for surface electromyography, captures facial expressions drum machine operator. These are...

This paper examines how digital systems designers distil the messiness and ambiguity of world into concrete data that can be processed by computing systems. Using Karen Barad's agential realism as a guide, we explore is fundamentally entangled with tools theories its measurement. We examine data-enabled artefacts acting Baradian apparatuses: they do not exist independently phenomenon seek to measure, but rather collect co-produce observations from within their state: apparatus co-constitute...

Current music emotion recognition (MER) systems rely on data averaged across listeners and over time to infer the expressed by a musical piece, often neglecting time- listener-dependent factors. These limitations can restrict efficacy of MER cause misjudgements. We present two exploratory studies perception. First, in live concert setting, fifteen audience members annotated perceived valence-arousal space using mobile application. Analyses inter-rater reliability yielded widely varying...

This paper discusses the design of Singing Knit, a wearable knit collar for measuring singer's vocal interactions through surface electromyography. We improve ease and comfort multi-electrode bio-sensing systems by adapting e-textile methods. The goal was to preserve capabilities rigid electrode sensing while addressing its shortcomings, focusing on reliability during extended wear, practicality convenience performance settings, aesthetic value. use conductive, silver-plated nylon jersey...

Explainable AI has the potential to support more interactive and fluid co-creative systems which can creatively collaborate with people. To do this, creative models need be amenable debugging by offering eXplainable (XAI) features are inspectable, understandable, modifiable. However, currently there is very little XAI for arts. In this work, we demonstrate how a latent variable model music generation made explainable; specifically extend MeasureVAE generates measures of music. We increase...

This paper investigates sound and music interactions arising from the use of electromyography (EMG) to instrumentalise signals muscle exertion human body. We situate EMG within a family embodied interaction modalities, where it occupies middle ground, considered as ''signal inside'' compared with external observations body (e.g., motion capture), but also seen more volitional than neurological states recorded by brain electroencephalogram (EEG). To understand messiness gestural afforded EMG,...

Through experience, the techniques used by professional vocalists become highly ingrained and much of fine muscular control needed for healthy singing is executed using well-refined mental imagery. In this paper, we provide a method observing intention embodied practice surface electromyography (sEMG) to detect activation, in particular with laryngeal muscles. sensing electrical neural impulses causing contraction, sEMG provides unique measurement user intention, where other sensors reflect...

This paper introduces micro-phenomenology, a research discipline for exploring and uncovering the structures of lived experience, as beneficial methodology studying evaluating interactions with digital musical instruments. Compared to other subjective methods, micro-phenomenology evokes returns one moment allowing access dimensions observations which may not be recalled in reflection alone. We present case study five micro-phenomenological interviews conducted musicians about their...

Multi-sensory experiences underpin embodiment, whether with the body itself or technological extensions of it. Vocalists experience intensely personal as vocalisation has few outwardly visible effects and kinaesthetic sensations occur largely within body, rather than through external touch. We explored this embodiment using a probe which sonified laryngeal muscular movements provided novel auditory feedback to two vocalists over month-long period. Somatic micro-phenomenological approaches...

Fabrics are seen as the foundation for e-textile interfaces but contribute their own tactile properties to interaction. We examine role of fabrics in gestural interaction from a novel, textile-focused view. replicated an eTextile sensor and interface rolling pinching gestures on four different fabric swatches invited 6 participants, including both designers lay-users, interact with them. Using semi-structured interview, we examined materials how they perceived movement feedback textile...

Music strongly modulates our autonomic nervous system. This modulation is evident in musicians' beat-to-beat heart (RR) intervals, a marker of rate variability (HRV), and can be related to music features structures. We present novel approach modeling RR interval variations, analyzing detailed components within piece extract continuous annotations performance decisions.

We present our musical performance exploration of liminal spaces, which focuses on the interconnected physicality bodies in music, using biosignals and gestural, movement-based interaction to shape live performances novel ways. Physical movement is important structuring performance, providing cues across ensembles, non-verbally informing other musicians intention. This especially true for improvised work. Our involves use musicking modulate audio signals. Three bespoke wearable nodes through...

In this preliminary study, we explored the relationship between auditory imagery ability and maintenance of tonal temporal accuracy when singing audiating with altered feedback (AAF). Actively performing participants sang audiated (sang mentally but not aloud) a self-selected piece in AAF conditions, including upward pitch-shifts delayed (DAF), speech distraction. Participants higher self-reported scores on Bucknell Auditory Imagery Scale (BAIS) produced reference that was less disrupted by...

This paper introduces my PhD research on the relationship which vocalists have with their voice. The voice, both instrument and body, provides a unique perspective to examine embodied practice. interaction voice is largely without physical interface it difficult describe sensation of singing; however, pedagogy has been successful at using metaphor communicate sensory experience between student teacher. I through several different perspectives, including experiential, physiological,...
