Installations intersect interactive concepts of Digital Musical Instruments, composition, and sound design. They require a design that is intuitive and impactful while also empowering the audience to perform with ease. One cannot build an installation successfully that involves a manual or practice. It must work in a straightforward manner, it must be simple and it must also enhance the connection of the audience with the material at hand. Considering aspects of user experience are important, ultimately the focus needs to be on musical interaction. Ultimately, understanding the needs of DMI design through improvisation and composition of electronic music through performance offers an important understanding to design installations can give guiding musical interactive principles, while considering sonic hierarchy, dimensional design, and intent one can begin to develop interactive systems that are meaningful and intuitive. Line Segment is an installation by Dirk Johan Stromberg that delves into an approach of a sonic, tactile installation that involves different levels and types of interactivity to allow the audience to be an important part of the composition.
