In this thesis we present the design and prototype implementation of a Digital Music Stand that focuses on fluid music layout management and free-form digital ink annotation. An analysis of user constraints and available technology lead us to select a 21.5” multi-touch monitor as the preferred input and display device. This comfortably displays two A4 pages of music side by side with space for a control panel. The analysis also identified single handed input as a viable choice for musicians. Finger input was chosen to avoid the need for any additional input equipment. To support layout reflow and zooming we develop a vector based music representation, based around the bar structure. This representation supports animation of transitions, in such a way as to give responsive dynamic interaction with multi-touch gesture input. In developing the prototype, particular attention was paid to the problem of drawing small, intricate annotation accurately located on the music using a fingertip. The zoomable nature of the music structure was leveraged to accomplish this, and an evaluation carried out to establish the best level of magnification. The thesis demonstrates, in the context of music, that annotation and layout management (typically treated as two distinct tasks) can be integrated into a single task yielding fluid and natural interaction.
