Abstract

A system and method are provided for a touch screen whose input is less influenced by turbulence, G forces, and/or equipment vibrations. A method of selecting one of a plurality of buttons displayed on a touch screen includes preventing buttons within a first portion of the touch screen from registering a touch; placing a portion of a hand on the first portion; and touching one of the plurality of buttons on a second portion of the touch screen.

Claims

1. A method of selecting one of a plurality of buttons displayed on a touch screen, each of the buttons configured to select an associated function of a plurality of functions, comprising:

determining a location of a region on a display in consideration of the location of the buttons;

displaying the region, the region preventing a sensing by one or more of the buttons by a positioning by a first portion of a user'"'"'s hand on the region over the one or more buttons; and

sensing the touch of a second portion of the user'"'"'s hand on one of the buttons not affected by the region to select the associated function of that button while the first portion of the user'"'"'s hand is positioned on the region.

2. The method of claim 1 further comprising a plurality of regions on the touch screen whose locations are based on the location of the plurality of buttons, and the positioning of the first portion of the user'"'"'s hand comprises:

sensing the first portion on the region.

3. The method of claim 1 further comprising:

sensing a gaze at one of the buttons; and

placing a region on the touch screen based on the location of the button for which the gaze was directed.

4. The method of claim 1 further comprising:

sensing a gaze at a desired button for selection; and

deactivating at least one other button from sensing a touch.

5. A method of selecting one of a plurality of buttons displayed on a touch screen, comprising:

determining a location of a region on a display in consideration of the location of the buttons;

displaying a region, the region preventing a sensing by one or more of the buttons by a positioning of a first portion of a user'"'"'s hand on the region over the one or more buttons; and

sensing the touch of a second portion of the user'"'"'s hand on one of the buttons not affected by the region while the first portion of the user'"'"'s hand is positioned on the region.

6. The method of claim 5 wherein the preventing step comprises:

providing a plurality of regions on the touch screen whose locations are based on the location of the plurality of buttons; and

sensing a portion of a hand on one of the plurality of regions.

7. The method of claim 6 further comprising:

sensing the movement of one of the regions.

8. The method of claim 7 further comprising:

changing the shape of the region during the movement.

9. The method of claim 8 further comprising:

changing the region to its shape prior to the movement when the movement has ceased.

10. The method of claim 5 wherein the preventing step comprises:

providing a region of a size sufficient to receive a palm of a hand.

11. The method of claim 5 further comprising:

determining a button at which a user is gazing; and

placing a region on the touch screen based on the location of the button for which the gaze is directed.

12. The method of claim 5 further comprising:

determining a button at which a user is gazing; and

deactivating at least one other button from sensing a touch.

13. The method of claim 5 further comprising:

determining a button at which a user is gazing; and

defining a viewport surrounding the desired button.

14. The method of claim 13 further comprising:

moving the viewport by the application of a moving touch.

15. The method of claim 5 wherein the preventing step comprises:

sensing a touch of the touch screen to define a plurality of touch points that define a region.

16. The method of claim 5 further comprising:

sensing the movement of the hand to change the location and shape of the region.

17. The method of claim 5 wherein the preventing step comprises:

sensing a gesture of a user to define a region.

18. A touch screen comprising:

a display screen;

first circuitry configured to display at least one character through the display screen on each of a plurality of buttons; and

second circuitry configured to sense touches applied to each of the plurality of buttons; and

a processor configured to;

display a region in which a touch by a first portion of a user'"'"'s hand to at least a portion of an underlying button will be ignored;

determining a location of the region on the display screen in consideration of the location of the buttons;

wherein the sensing of touches of a second portion of the user'"'"'s hand as applied to each of the plurality of buttons is not affected by the region while the first portion of the user'"'"'s hand is positioned on the region.

19. The touch screen of claim 18 wherein the processor is further configured to:

determine the location of the region based on the location of the plurality of buttons.

20. The touch screen of claim 18 wherein the processor is further configured to:

determine a button at which a user is gazing; and

place a region on the touch screen based on the location of the button for which the gaze is directed.

21. The touch screen of claim 18 wherein the processor is further configured to:

determine a button at which a user is gazing; and

preventing at least one other button from sensing a touch.
