Voice Navigation to Help Blind Users Learn Special Key Assignments

      Disclosed is a voice navigation technique for learning the
special key assignments of individual applications non-visually.  It
allows blind people to learn such key assignments easily when they
start using a new application.

      When an assigned key is pressed, the user hears a spoken
description of the function assigned to it.  Since the function
assignments vary according to the applications, the descriptions
associated with particular keys depend on the application.

      The Figure shows an example in which the user navigates some
application controlled by a numeric keypad.  When key 8 is pressed,
the system changes to voice navigation mode, and a key operation
manual is  read.  When key 8 is pressed again, the system changes to
key function  echo mode.

      In this mode, it gives a spoken description of the assigned
function when any key is pressed.  For example, when key 7 is
pressed, it says "the pointer is moved to the top of the page and you
can read from the beginning".

      In other words, it tells the user the function of the key
instead of saying "this is key 7".  This technique is not limited to
a numeric keypad; it can be applied to all the keys on a keyboard,
and also to the keys on vending machines and other domestic
appliances.
