Fast and Accurate Prototyping of Input Devices for Expert Interaction

这项研究计划旨在探索音乐环境中人机交互的创新软硬件系统的发展。它将支持我的长期研究工作，重点是将电子和软件开发应用于数字乐器(DMIS)的设计，即基于控制由软件算法产生的声音(和/或其他媒体)的输入设备的乐器。DMIS的设计是一个在过去十年里受到极大关注的研究领域，这在一定程度上要归功于音乐表达新界面国际会议(NIME)和越来越多的DIY设计师社区。 在这项拟议的研究中，我将从三个角度探讨DMIS的设计和评估： -DMIS的快速原型设计：利用3D打印机和激光切割机等快速原型工具设计创新的DMIS，从而能够在快速开发-测试周期内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表演者的协作项目中至关重要，这些表演者需要立即访问设备，以便向设计师提供反馈，说明在哪里可以改进设备。 -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，或组合来自多种数字信号处理技术处理的几个传感器的数据。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，可以为需要准确和可重复的性能测量的交互式应用设计响应性的DMIS(Medeiros&Wanderley，正在审查中)。与嵌入式声音合成和映射工具(如libmapper)一起，将有可能创建自包含的、响应性强的DMIS。 -改进评估DMIS的方法：在我们最近的工作和最近对DMI文献的贡献的基础上，我们将使用定性和定量相结合的方法来完善评估DMIS的方法，以了解表演者如何与其乐器互动，以及性能专业知识如何随着时间的推移而发展。这一理解反过来将对新型DMIS的设计起到重要作用。 这项研究的预期影响是多方面的，无论是在多学科研究背景下培训高素质人员，还是在开发音乐表现工具和在专家背景下与计算机互动所产生的商业和社会效益方面。

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.
