Augmented Sound

A Computer Vision System for doing Interactive Installations This thesis is a computer vision system for doing interactive-creative musical installations: A portable computer vision system based on video projection and a green laser, that allows the interaction with the projection itself, with the physical space where it is projected and with multiple users. By using a green laser as a physical user interface, people create projections of sound balls that are projected on top of objects. These balls interact with the physical characteristics of the object where they are projected, as well as with other balls that where previously created in the same space. When this interaction happens they produce sound, which varies depending on several rules that are initially set up. Depending on the complexity of these interactive relationships between the projection (balls), the space where the projection is projected (objects) and the user, it creates a new aesthetic sound and visual layer as an expansion of the object that can also be called augmented sound
