Abstract

A touch control panel for a cathode ray tube display system that provides for a command entry device. The control panel comprise a touch sensitive panel adapted to produce different output signals depending upon where it is contacted. A processor is coupled to the panel for processing the output signals to select and then display a particular pop-up menu from a plurality of stored menus. An activation switch is provided to select the currently highlighted menu as selected via the touch sensitive panel.

Claims

1. A touch control panel for use with a cathode ray tube display, said touch control panel comprising:

a touch sensitive panel for generating a plurality of output signals as a function of where the touch sensitive panel is contacted with a finger;

processing means coupled between the touch sensitive panel and the cathode ray tube display for receiving and processing the plurality of output signals to select a predefined pop-up menu from a plurality of menus stored therein and for displaying and highlighting the predefined menu on the cathode ray tube display; and

activation means disposed adjacent the touch sensitive panel and coupled to the processing means for activating the highlighted pop-up menu selected by means of the touch sensitive panel.

2. The touch control panel of claim 1, wherein the panel comprises means for producing the output signals as a function of a localized change in capacitance.

3. The touch control panel of claim 1, wherein the panel comprises means for producing the output signals as a function of a localized change in an acoustic characteristic.

4. The touch control panel of claim 1, wherein the panel comprises means for producing the output signals as a function of a localized change in resistance.

5. The touch control panel of claim 1, wherein the panel comprises means for producing the output signals as a function of a localized change in AC impedance.

6. The touch control panel of claim 1 wherein the activation means is a pressure sensitive switch, which when depressed, is first actuated to produce a signal locking the displayed menu on the cathode ray tube display, is then actuated to produce a signal actuating a function selected from the menu, and is then actuated to reset the system after the selected function has been displayed.

7. A touch control panel for use with a cathode ray tube display, said touch control panel comprising:

a touch sensitive panel for generating a plurality of output signals as a function of where the touch sensitive panel is contacted;

processing means coupled between the touch sensitive panel and the cathode ray tube display for receiving and processing the plurality of output signals to select a predefined pop-up menu from a plurality of menus stored therein and for displaying and highlighting the predefined menu on the cathode ray tube display; and

activation means disposed adjacent the touch sensitive panel and coupled to the processing means for activating the highlighted pop-up menu selected by means of the touch sensitive panel, said activation means comprising a pressure sensitive switch, which when depressed, is first actuated to produce a signal locking the displayed menu on the cathode ray tube display, is then actuated to produce a signal actuating a function selected from the menu, and is then actuated to reset the system after the selected function has been displayed.

8. The touch control panel of claim 7, wherein the panel comprises means for producing the output signals as a function of a localized change in capacitance.

9. The touch control panel of claim 7, wherein the panel comprises means for producing the output signals as a function of a localized change in an acoustic characteristic.

10. The touch control panel of claim 7, wherein the panel comprises means for producing the output signals as a function of a localized change in resistance.

11. The touch control panel of claim 7, wherein the panel comprises means for producing the output signals as a function of a localized change in AC impedance.

12. A touch control panel for use with a cathode ray tube display, said touch control panel comprising:

a touch sensitive panel for generating a plurality of output signals as a function of where the touch sensitive panel is contacted;

processing means coupled between the touch sensitive panel and the cathode ray tube display for receiving and processing the plurality of output signals to select a predefined pop-up menu from a plurality of menus stored therein and for displaying and highlighting the predefined menu on the cathode ray tube display; and

activation means disposed adjacent the touch sensitive panel and coupled to the processing means for activating the highlighted pop-up menu selected by means of the touch sensitive panel.
