  • Patent number: 10073532
    Abstract: A system for a spatial-gesture user interface employing grammatical rules at various levels. Various distinct subset of the gestemes can be concatenated in space and time to construct a distinct gestures. Real-time spatial-gesture information measured by a spatial-gesture user interface is processed to at least a recognized sequence of specific gestemes and that the sequence of gestemes that the user's execution a gesture has been completed. The specific gesture rendered by the user is recognized according to the sequence of gestemes. Many additional features are then provided from this foundation, including gesture grammars, structured-meaning gesture-lexicon, imposed interpretations, context, and the use of gesture-rendering prosody. The invention can be used to provide very general spatial-gesture grammar user interface for touchscreens, high dimensional touch pad (hdtp), free-space camera, and other user interfaces.

  • Patent number: 10037186
    Abstract: Multichannel data sonification arrangements for providing parallel perceptual channels for representing complex numerical data to a user seeking to identify correlations within the data are presented. In an implementation, several varying data quantities are represented by time-varying sound and presented to a user to observe both variations and correlations among sonic events or trends.

  • Publication number: 20180107370
    Abstract: This invention provides a signal processing and signal synthesis technique from a family of signal processing and signal synthesis techniques designed to readily interwork or be used individually in creating new forms of rich musical timbres. A real-time controllable mix of a plurality of multiple output frequency-reduced signals and the cross-products of these signals provides rich animated harmonically partitioned spectra. Mixing parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including envelope generators, low-frequency oscillators, and those derived from an original input signal, and specifically including the amplitude of an original input signal. The real-time controllable mix may have multiple outputs and be subjected to further signal processing and multiple-channel amplification.
