Abstract

Methods for presenting symbolic expressions such as mathematical, scientific, or chemical expressions, formulas, or equations are performed by a computing device. One method includes: displaying a first portion of a symbolic expression within a first area of a display screen; while in a first state in which the first area is selected for aural presentation, aurally presenting first information related to the first portion of the symbolic expression; while in the first state, detecting particular user input; in response to detecting the particular user input, performing the steps of: transitioning from the first state to a second state in which a second area, of the display, is selected for aural presentation; determining second information associated with a second portion, of the symbolic expression, that is displayed within the second area; in response to determining the second information, aurally presenting the second information.

Claims

1. A computer-implemented method, comprising:

at a computing device with a display;

displaying a first portion of a symbolic expression within a first area of the display;

while in a first state in which the first area is selected for aural presentation, aurally presenting first information related to the first portion of the symbolic expression;

while in the first state, detecting particular user input;

in response to detecting the particular user input;

transitioning from the first state to a second state in which a second area of the display is selected for aural presentation;

determining second information associated with a second portion of the symbolic expression that is displayed within the second area;

in response to determining the second information, aurally presenting the second information.
