Abstract
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.
