Action-Sound Latency: Are Our Tools Fast Enough?
TLDR
This dissertation aims to provide a history of web exceptionalism from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year in which descriptions of “Web 2.0” began to circulate.

An Environment for Submillisecond-Latency Audio and Sensor Processing on BeagleBone Black
TLDR
This paper presents a new environment for ultra-low-latency processing of audio and sensor data on embedded hardware based on the low-cost BeagleBone Black single-board computer and uses the Xenomai real-time kernel extensions to achieve latency as low as 80 microseconds.
Design for longevity: ongoing use of instruments from nime 2010-14
TLDR
This work contacted 97 DMI makers that presented a new instrument at five successive editions of NIME and proposed a series of design considerations for future DMIs, reflecting on the specific factors that facilitated and those that hindered instrument longevity.

The Problem of the Second Performer: Building a Community Around an Augmented Piano
TLDR
The magnetic resonator piano is presented, an electronically augmented acoustic grand piano that uses electromagnets to induce vibrations in the strings that demonstrates how a new instrument can acquire a community of musicians beyond those initially involved.

The space between the notes: adding expressive pitch control to the piano keyboard
TLDR
A system for controlling pitch from the keyboard surface using capacitive touch sensors to measure the locations of the player's fingers on the keys and evaluates the usability of the continuous pitch control system.

Dimensionality and Appropriation in Digital Musical Instrument Design
TLDR
Results show that the addition of a second degree of freedom had the counterintuitive e↵ect of reducing the exploration of the instrument’s a↵ordances; this suggested the presence of a dominant constraint in one of the two configurations which strongly di↵erentiated the process of appropriation across the two groups of participants.

Techniques and Circuits for Electromagnetic Instrument Actuation
TLDR
The material in this paper forms the basis of the magnetic resonator piano, an electromagnetically-augmented acoustic grand piano now in its second design iteration, and aims to provide a toolbox to accelerate the design of new hybrid acoustic-electronic instruments.

Smart instruments : Towards an ecosystem of interoperable devices connecting performers and audiences
This paper proposes a new class of augmented musical instruments, “Smart Instruments”, which are characterized by embedded computational intelligence, bidirectional wireless connectivity, an embedd…
Skip the Pre-Concert Demo: How Technical Familiarity and Musical Style Affect Audience Response
TLDR
Results showed that receiving an explanation increased the reported understanding of that instrument, but had no effect on either the reported level of interest or enjoyment, while performances in experimental versus conventional style on the same instrument received widely divergent audience responses.

The Magnetic Resonator Piano: Electronic Augmentation of an Acoustic Grand Piano
TLDR
The magnetic resonator piano is a hybrid acoustic-electronic instrument extending the traditional grand piano, using electromagnetic actuators to directly manipulate the piano strings, expanding its vocabulary to include infinite sustain, notes that crescendo from silence, harmonics, and a variety of timbres.
