The method includes providing a user interface that includes a plurality of metaphors and spatial sound rendering operations resulting in stereo audio output. In one implementation, a metaphor is used in making parameter assignments according to which audio-frequency waveforms having adjustable timbre attributes are generated. In another implementation, timbre attributes are adjustable over a range of timbre variation and are further associated with corresponding metaphors. | 08-15-2013 |
| 20140150629 | JOINT AND COORDINATED VISUAL-SONIC METAPHORS FOR INTERACTIVE MULTI-CHANNEL DATA SONIFICATION TO ACCOMPANY DATA VISUALIZATION - Data sonification arrangements for use with data visualization so as to provide 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 graphics while several other varying data quantities are represented by time-varying sound, both presented to a user to observe correlations between sonic and visual events or trends. Sonification can be used to offload some information-carrying information capacity from a visualization system, while other information can be rendered via both sonification and visualization to provide affirming or orienting redundancy. In an implementation joint and coordinated visual-sonic metaphors are used for this or other purposes. For example, data sonification can include multiple data-modulated sound timbre classes, each rendered within a stereo sound field according to a spatial metaphor that is shared with the visualization. | 06-05-2014 |
