Audio-Assisted Dialing for Phones with Touch Screens

      Disclosed is a hardware implementation to provide audio
assisted dialing for phones with liquid crystal display (LCD)
screens.  The implementation provides an audio feedback during touch
screen scanning to aid the user in navigating the phone numbers on
the touch screen during a dialing operation.

      Typically, mobile phones that are used while a vehicle is in
motion must not distract the user's vision, or require more than one
hand to operate.  Because of space limitations, phones that use touch
screens for dialing have no tactile feedback with which to orient a
user's dialing finger.  In order to minimize visual aberrations, the
screen is a smooth flat surface that provides no tactile feedback.
As a result, dialing requires the user to look at the device in order
to orient the placement of the finger on the displayed screen.
Because of visual dangers involved, this approach is not considered
satisfactory.

      The described concept herein is designed to provide audio
feedback, such as a voice calling out the numbers, as the user's
finger is moved across the screen.  When the user touches and hears a
number corresponding to the required number to be dialed, the finger
is released, or pressed, onto the screen.  The number is then
actuated for dialing and an audio announcement takes place.  This
approach requires no visual attention which could distract the
operator from a visual task.
