本文讨论的问题是如何以尊重用户现有专业知识的方式扩展良好建立的界面的功能。钢琴风格的键盘是使用最广泛、用途最广的数字音乐接口之一。然而，它缺乏在演奏完音符后改变音高的能力，这一限制阻止了表演者执行常见的表达技巧，包括颤音和音调弯曲。我们提出了一种使用电容式触摸传感器从键盘表面控制音调的系统，以测量玩家手指在按键上的位置。训练有素的钢琴家的庞大社区使键盘成为一个引人注目的增强目标，但它也带来了一个挑战：如何在利用表演者花费数千个小时学习的现有技术的同时扩展音乐界面？本文通过对音乐学院钢琴家的用户研究，探讨了传统键盘技术的局限性，并对连续音高控制系统的可用性进行了评估。本文还讨论了在音乐和非音乐环境中扩展其他已建立的接口的意义。
This paper addresses the question of how to extend the capabilities of a well-established interface in a way that respects users' existing expertise. The piano-style keyboard is among the most widely used and versatile of digital musical interfaces. However, it lacks the ability to alter the pitch of a note after it has been played, a limitation which prevents the performer from executing common expressive techniques including vibrato and pitch bending. We present 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. The large community of trained pianists makes the keyboard a compelling target for augmentation, but it also poses a challenge: how can a musical interface be extended while making use of the existing techniques performers have spent thousands of hours learning? In this paper, user studies with conservatory pianists explore the constraints of traditional keyboard technique and evaluate the usability of the continuous pitch control system. The paper also discusses implications for the extension of other established interfaces in musical and non-musical contexts.
