BounceSlider: Actuated Sliders for Music Performance and Composition
Paper in proceedings, 2008
The ForceFeedback Slider (FFS) is a one-dimensional actuated slider using a motor to produce tangible interaction with position and force as input and output parameters. To create a new concept, we have built a mixing desk, placed six FFSs (two implemented here) into a partially realized SliderBox, and added a LED and two toggle buttons to each slider for additional interactivity. We have developed a tool called BounceSlider for improvising music. This application for real time music performance and composition uses a slider handle that can act as a ball. Users can lift and release the handle to set the ball in motion and produce a particular sound each time it bounces against the baseline. Based on physical characteristics, the user can create different sounds and loops by changing two settings: gravity (speed) and bounce type (ball physical characteristics). BounceSlider allows the user to create and save loops of Musical Instrument Digital Interface (Midi) with up to five sounds at a time.
