The impact of physical dimensions on musical gestural interaction in large digital musical instrument design

本研究是关于超大型数字乐器设计对音乐手势交互的影响，超大型数字乐器设计是指物理尺寸大于人体但小于房间大小的乐器。当与界面交互时，不仅执行者移动他们的身体来控制界面，界面设计和示能表示控制执行者移动他们的身体的方式。在DMIs的上下文中，具有相同声音能力的两种乐器将根据其物理布局引起不同的手势交互模式。本研究以探讨研究问题为目的，运用乐器设计的方法论，以大型乐器演奏者的手势互动为研究对象，探讨乐器尺寸的变化如何最终影响演奏者的手势语言，进而影响他们的作曲选择。每项研究都考察了在大型DMIs上进行的启示和惯用手势语言的各种因素对性能和组成的相对影响。研究表演者在大型乐器上的互动，这些乐器具有新颖的布局，参与者尚未开发出惯用的手势语言，这将导致与大型乐器以及各种尺寸乐器的设计相关的新发现。这项研究将是相关的数字乐器设计师和人机交互研究人员，因为它将阐明的影响，一个数字乐器的物理尺寸和布局上的性能和使用数字乐器创建的作品，使设计师可以做出明智的决定，要么支持或抑制在未来的数字乐器设计的具体影响。此外，通过这项研究，我将有助于设计一个新的家庭的数字乐器，可以使用的数字乐器表演者和研究人员在未来。

This research is about the impact on musical gestural interaction of over-sized Digital Musical Instrument (DMI) design, that is instruments with physical dimensions that are larger than the human body performing them but smaller than the size of the room they are in. When interacting with an interface not only does the performer move their body to control the interface, the interface design and affordances control the way the performer moves their body. In the context of DMIs, two instruments with the same sonic capabilities will elicit different patterns of gestural interaction depending on their physical layout. Using the methodology of designing instruments for the purpose of exploring research questions, this research examines the gestural interaction made by performers on large DMIs to investigate how changes in size ultimately shape the gestural language of the performer, and through that the compositional choices they make.This research investigates gestural interaction and how it shapes compositional choices through three studies. Each study examines the relative effects on performance and composition of various factors of affordances and idiomatic gestural language performed on large DMIs. Studying performer interactions on large instruments with novel layouts that participants have not yet developed idiomatic gestural languages will result in new discoveries that are relevant to the design of large instruments as well as instruments of all sizes. This research will be relevant for digital musical instrument designers and Human Computer Interaction researchers as it will elucidate the influence that a DMI's physical size and layout has on the performances and compositions created using digital musical instruments, so that designers can make informed decisions to either support or suppress specific influences in future DMI design. Further, through this research, I will contribute the design of a new family of digital musical instruments that can be used by digital musical instrument performers and researchers in the future.
