Abstract: Embodiments include systems and methods for synthesizing, recording, performing and playing back visual music for virtual immersive video playback environments. Virtual music (VM) compositions can include 3D VM instruments, which can be controlled in a highly dynamic and expressive manner using human interface controllers. Some embodiments include novel techniques for controlling, synthesizing, and rendering VM instruments having complex particle system architectures. Some embodiments further provide VM compositional techniques built on four-dimensional modeling constructs that include path-adaptive coordinate systems that define a compositional space-time for modeling, and path-anchored object locators that place objects in the compositional space-time.

Abstract: A system and method for assigning visual markers to the output of a filter bank to establish a visual correspondence between octave equivalent outputs. The system includes an analyzer module and a graphic processing module. The analyzer module receives filter outputs from the filter bank, which has received as input a wave signal spanning multiple octaves. The graphic processing module generates a graphic image including displays of the filter outputs. The analyzer module assigns display sets to the filter outputs, assigns octave equivalence classes to display sets, and assigns visual markers to octave equivalence classes. The graphic processing module generates the displays of the filter outputs in the graphic image based on the assigned visual markers, the assigned octave equivalence classes, and the assigned display sets.

Abstract: A method for calibrating an electronic vision device, such as a personal glare reduction device, having a darkened spot in its field of view includes the steps of fixing the lens coordinates of the darkened spot to correspond to a calibration site in the field of view, and moving the glare reduction device to place the darkened spot in line with the glare source. A processor evaluates a correction angle on the basis of the new direction to the glare source, as measured by a directional light sensor on the glare reduction device. The apparatus of the invention includes a controller that includes the processor, a memory, a light sensor, and a user interface element.
