System for audible feedback for touch screen displays
What is presented is a system and method by which a visually impaired worker could easily and quickly navigate menu options on touch screen displays. An Audible Feedback ON/OFF Switch is provided which turns the audible feedback feature of the present invention on or off. The software monitoring which row/column areas of the touch screen's display grid have been touched by the user in response to a menu option selection is made switchable into one of two modes. A first mode is when the audible feedback feature is OFF or otherwise disabled. In this mode the software operates the touch screen's menu selections in the normal manner in which the machine is intended to perform. When a user selects an option, the option is immediately activated whether it be a machine activity or a jump to another level of menus. A second mode is when the audible feedback feature has been turned ON or otherwise activated. In this mode a two step process is activated such that when a user makes a first touch of a menu option a sound or voice is audibly played indicating the nature of the particular menu option just selected. A second consecutive touch of the same menu option then actually activates the machine activity associated with that particular menu option.
1. A system for providing audible feedback to enable a visually impaired person to operate a multi-function machine, comprising:
touchable elements means for selecting a plurality of selectable system options associated with features of the multi-function machine;
audible feedback means for generating electrical signals that provide audible instructions to the visually impaired person as to one or more options are selected;
means for enabling/disabling said audible feedback means such that when said audible feedback means is disabled, no electrical signals corresponding to the audible instructions to the visually impaired person are generated and when said audible feedback means is enabled, electrical signals corresponding to the audible instructions to the visually impaired person are generated; and
a controller to control navigation of said selectable system options and to provide instructions for the operation of the multi-function machine;
said controller checking whether audible feedback is disabled;
said controller, if said audible feedback is disabled, activating a process associated with a selection made on said touchable elements;
said controller providing audible feedback corresponding to the selection made when said audible feedback is enabled;
said controller, when said audible feedback is enabled, comparing the selection made with a previous selection made;
said controller providing, when said audible feedback is enabled and the selection made and the previous selection made are different, only audible feedback corresponding to the selection made and not activating the process associated with the selection made;
said controller, if the selection made and the previous selection made are the same, providing audible feedback corresponding to the selection made and activating a process associated with the selection made.
2. The system as claimed in claim 1 , wherein said touchable elements menu means comprises a touch screen display for navigating menu selections and machine operations thereof.
3. The system as claimed in claim 1 , wherein said audible feedback means comprises at least one sound generation mechanism.
4. The system as claimed in claim 1 , wherein said means for enabling/disabling said audible feedback means comprises a selectable button switch, said selectable button switch causing said audible feedback means to be disabled when initiating a first state and enabled when initiating a second state.
5. The system as claimed in claim 1 , wherein the multi-function business machine comprises at least one from the set of printers, scanners, faxes, copiers, and manufacturing and production equipment.
6. The system as claimed in claim 5 , wherein said audible feedback means indicating that the audible feedback has been disabled when said selectable button switch initiates the first state.
7. The system as claimed in claim 1 , wherein said audible feedback means provides audible feedback as to an identity of a menu selection option just touched.
