LAMI: A gesturally controlled three-dimensional stage Leap (Motion-based) Audio Mixing Interface

Interface designers are increasingly exploring alternative approaches to user input/control. LAMI is a Leap (Motion-based) AMI which takes user’s hand gestures and maps these to a three-dimensional stage displayed on a computer monitor. Audio channels are visualised as spheres whose Y coordinate is spectral centroid and X and Z coordinates are controlled by hand position and represent pan and level respectively. Auxiliary send levels are controlled via wrist rotation and vertical hand position and visually represented as dial-like arcs. Channel EQ curve is controlled by manipulating a lathed column visualisation. Design of LAMI followed an iterative design cycle with candidate interfaces rapidly prototyped, evaluated and refined. LAMI was evaluated against Logic Pro X in a defined audio mixing task.
