Calculator for the Visually Impaired

      This invention provides the ability for the visually impaired
to use an electronic calculator via touch and voice interface.

      This invention provides a voice interface feature for
electronic calculators.  The advantage of the voice interface
mechanism for electronic calculators allows visually impaired users
to improve proficiency and accuracy of input for calculating
numerical and scientific values.

      The voice interface will allow the user to enter verbal input
to be calculated.  When the input is received, it will be stored
temporarily.  The user will have the ability to request the input
from the calculator by issuing a verbal command.  When the command is
received by the calculator, it will respond verbally with the
information given as input by the user.  When the calculator
completes the calculation, it will provide the output to the user
verbally.  The user will have the ability to request the output to be
repeated by requesting it verbally.

      The keys on the keyboard will have numeric values, scientific
values and operands which will be written in braille.  This invention
will allow the user to turn off the verbal input response, so that
Key Pad response can be enabled.  When the verbal input response is
off and Key Pad input is entered, the Voice interface mechanism will
repeat each key stroke verbally to the user.  This feature will allow
the user to correct input errors.
