Fast and Accurate Prototyping of Input Devices for Expert Interaction

本研究计划旨在探索在音乐环境中，开发创新的软体与硬体系统，用于人机互动。它将支持我的长期研究工作，重点是电子和软件开发在数字乐器（dmi）设计中的应用，这些乐器基于一个输入设备，控制由软件算法产生的声音（和/或其他媒体）。dmi的设计是一个在过去十年中受到广泛关注的研究领域，这在一定程度上要归功于音乐表达新界面国际会议（NIME）和一个越来越大的diy设计师社区。在这项拟议的研究中，我将从三个角度来探讨DMIs的设计和评估：- DMIs的快速原型设计：创新的DMIs设计利用快速原型工具，如3D打印机和激光切割机，允许在快速开发-测试周期中创建适应用户需求的独特设备形式。这种快速循环在涉及专业人员的合作项目中是必不可少的，他们需要立即访问设备，以便他们能够向设计师提供改进的反馈。- DMIS的传感器融合和嵌入式计算：使用先进的仪器技术，如传感器融合，或通过各种数字信号处理技术处理来自多个传感器的数据的组合。传感器融合与处理原始传感器数据的先进仪器技术相结合，可以为需要精确和可重复性能测量的交互式应用设计响应式dmi （Medeiros & Wanderley，正在审查中）。与嵌入式声音合成和绘图工具（如libmapper）一起，它将有可能创建自包含的、响应的dmi。-改进评估DMI的方法：基于我们最近的工作和对DMI文献的最新贡献，我们将改进评估DMI的方法，使用定性和定量方法相结合的方法来了解表演者如何与他们的乐器互动，以及演奏专业知识如何随着时间的推移而发展。这种理解反过来对新型dmi的设计也很重要。这项研究的预期影响是很多的，无论是在多学科研究背景下培养高素质的人才，还是在商业和社会效益方面，都是由音乐表达工具的发展和专家背景下与计算机的互动所产生的。

This research proposal aims to explore the development of innovative software and hardware systems for human-computer interaction in musical contexts. It will support my long-term research work focusing on the application of electronics and software development to the design of digital musical instruments (DMIs), instruments that are based on an input device that controls sound (and/or other media) generated by software algorithms. The design of DMIs is a research field that has received substantial attention in the last decade, thanks in part to the international conference on New Interfaces for Musical Expression (NIME) and to an increasingly large community of do-it-yourself designers. In this proposed research, I will approach the design and evaluation of DMIs from three perspectives: - Rapid Prototyping of DMIS: The design of innovative DMIs taking advantage of rapid prototyping tools such as 3D printers and laser cutters, allowing for the creation of unique device forms adapted to user needs in a fast development-test cycle. This fast cycle is essential in collaborative projects involving expert performers, who need to have immediate access to devices so that they can provide feedback to designers on where to improve them. - Sensor Fusion and Embedded Computing for DMIS: The use of advanced instrumentation techniques such as sensor fusion, or the combination of data from several sensors processed by a variety of digital signal processing techniques. Sensor fusion, in tandem with advanced instrumentation techniques for processing raw sensor data, can lead to the design of responsive DMIs for interactive applications that demand accurate and repeatable performance measurements (Medeiros & Wanderley, under review). Together with embedded sound synthesis and tools for mapping such as libmapper, it will be possible to create self-contained, responsive DMIs. - Refinement of a methodology for the evaluation of DMIs: Building upon our recent work and on the recent contributions to the DMI literature, we will refine a methodology for the evaluation of DMIs using a combination of qualitative and quantitative methodologies to understand how performers interact with their instruments and how performance expertise develops over time. This understanding will be in turn important to inform the design of novel DMIs. The expected impacts of the research are numerous, both in terms of training high-qualified personnel in a multi-disciplinary research context, and in commercial and social benefits derived from the development of tools for musical expression and for the interaction with computers in expert contexts.
