How far away is plug 'n' play? Assessing the near-term potential of sonification and auditory display
The commercial music industry offers a broad range of plug 'n' play hardware and software scaled to music professionals and scaled to a broad consumer market. The principles of sound synthesis utilized in these products are relevant to application in virtual environments (VE). However, the closed architectures used in commercial music synthesizers are prohibitive to low-level control during real-time rendering, and the algorithms and sounds themselves are not standardized from product to product. To bring sound into VE requires a new generation of open architectures designed for human-controlled performance from interfaces embedded in immersive environments. This presentation addresses the state of the sonic arts in scientific computing and VE, analyzes research challenges facing sound computation, and offers suggestions regarding tools we might expect to become available during the next few years. A list of classes of audio functionality in VE includes sonification -- the use of sound to represent data from numerical models; 3D auditory display (spatialization and localization, also called externalization); navigation cues for positional orientation and for finding items or regions inside large spaces; voice recognition for controlling the computer; external communications between users in different spaces; and feedback to the user concerning his own actions or the state of the application interface. To effectively convey this considerable variety of signals, we apply principles of acoustic design to ensure the messages are neither confusing nor competing. We approach the design of auditory experience through a comprehensive structure for messages, and message interplay we refer to as an Automated Sound Environment. Our research addresses real-time sound synthesis, real-time signal processing and localization, interactive control of high-dimensional systems, and synchronization of sound and graphics
A Priori Attunement for Two Cases of Dynamical Systems
Presented at the 20th International Conference on Auditory Display (ICAD2014), June 22-25, 2014, New York, NY.An application of a tuning function adopts a space metaphor in
scientific methods for representing state space of non-linear
dynamical systems. To achieve an interactive exploration of
the systems through sounds, attunement is defined as an a
priori process for conditioning a playable space for an
auditory display. To demonstrate this process, two cases of
dynamical systems are presented. The first case employs
Chua’s circuit, in which system parameters are defined as
energy introduction to the system and energy governance
within the system. The second case employs a swarm
simulation, defined as a set of rules to dictate social agents’
behaviors. Both cases exhibit complex dynamics and emergent
properties. The paper synthesizes a comparative review of
auditory display for the two cases while defining playable
space with generalizable tuning functions. The scope of the
discussion focuses on the relationship between playable space
as a canonical architecture for auditory display workflow and
its realization through attunement in applications of dynamical
systems
Towards a Chaotic Musical Instrument
The goal of this project is to produce a software musical instrument using chaotic processes as a sound synthesis method. Real-time control through MIDI note messages and continuous controllers is required. Early results are described, along with suggestions for continuing work

Constraint satisfaction modules : a methodology for analog circuit design
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.Includes bibliographical references (p. 119-122).This dissertation describes a methodology for solving convex constraint problems using analog circuits. It demonstrates how this methodology can be used to design circuits that solve function-fitting problems through iterated gradient descent. In particular, it shows how to build a small circuit that can model a nonlinearity by observation, and predistort to compensate for this nonlinearity. The system fits into a broader effort to investigate non-traditional approaches to circuit design. First, it breaks the traditional input-output abstraction barrier; all ports are bidirectional. Second, it uses a different methodology for proving system stability with local rather than global properties. Such stability arguments can be scaled to much more complex systems than traditional stability criteria.by Piotr Mitros.Ph.D

An Educational Coding Laboratory for Elementary Pre-service Teachers: A Qualitative Approach
The present study involved 64 pre-service teachers in a first experience of coding with the software Scratch, foreseeing its qualitative evaluation. In particular, the procedure in the laboratorial setting was designed as follows: firstly, subjects attended theoretical lessons on the use of the software, ideated and implemented an educational app. Afterwards, subjects wrote a report on the negative and positive aspects of their laboratorial experience. The analysis of results show that pre-service teachers appreciated the collaborative work, the freedom to code an app following their own interests, and the use of an engaging software. A constant concern regarding teachers' self-efficacy as future mentors was present. Further quantitative studies are necessary
