Architecture for communicating data values that enables visually impaired persons to perceive a non-image indicator corresponding to the data values. For example, an organized data set such as a chart or a graph can be displayed on a computer monitor or other user interface output component. A user employs a mouse or other user input component to select a data value from the organized data set. A non-image indicator such as an audible tone can be generated to correspond to the selected data value. A spread of audible tones corresponding to the organized data set is assigned across a range between a maximum data value and a minimum data value. A tonal separation is assigned between audible tones sufficient to enable the user to discern a pitch variation and corresponding change in data value. |
