Transforming a tactually selected user input into an audio output

摘要

A contextual input device includes a plurality of tactually discernable keys disposed in a predetermined configuration which replicates a particular relationship among a plurality of items associated with a known physical object. The tactually discernable keys are typically labeled with Braille type. The known physical object is typically a collection of related items grouped together by some common relationship. A computer-implemented process determines whether an input signal represents a selection of an item from among a plurality of items or an attribute pertaining to an item among the plurality of items. Once the selected item or attribute pertaining to an item is determined, the computer-implemented process transforms a user's selection from the input signal into an analog audio signal which is then audibly output as human speech with an electro-acoustic transducer.

主权项

1. A computer implemented process for transforming a user input into an audio output comprising:
receiving a digital input signal from a contextual input device, the contextual input device comprising a plurality of tactually discernable keys disposed in a spatial relationship which proportionally replicates a spatial relationship among a plurality of planets and stars associated with a solar system; determining whether the digital input signal represents a selection of one of the planets and stars or an attribute pertaining one of the planets and stars; transforming the digital input signal into an analog audio signal; outputting the analog audio signal with an electro-acoustic transducer.
