In addition, physical computer interface devices not intended specifically for music, such as a mouse, have been frequently used to perform or shape computer music processes. The abundance of successful research will insure composers reliable and accurate movement data. With many of these technicalities solved, some attention can now be shifted away from instrument building and towards musical performance and composition. It is doubtful that such movement data can be simply applied to pre-existing musical models. An examination of the physical parameters of movement, their limitations, and the methods used for their measurement, will yield clues to an appropriate musical response, one where imaginative connections engage performers by their power to shape sound.
Physical energy is transformed into sound through a musical instrument mechanism.
Two different classes of movement transducers are the focus of this discussion. Although the wide variety of devices for detecting movement have unique sensing apparatuses, capabilities, and features, many share common attributes. Spatial sensors detect location in space, by proximity to hardware sensors or by location within a projected grid. Body sensors measure the angle, force, or position of various parts of the body. These two methods are by no means mutually exclusive.
