System and method for guarding emergency and critical touch targets
First Claim
Patent Images
1. A method, executable by a processor, for displaying a plurality of buttons on a touch screen device configured to sense touch input, the method comprising:
- displaying, using a first design, non-critical buttons;
displaying, using a second design that is different than the first design, a guarded critical button, wherein the second design causes the guarded critical button to appear to have an overlaid object on it;
rendering the guarded critical button as a third design that is different from the first design and different from the second design responsive to sensing a first touch input associated with the second design of the guarded critical button, wherein the third design causes the guarded critical button to appear to have the overlaid object partially removed;
sensing second touch input associated with the third design of the guarded critical button;
processing a combination of the first touch input and second touch input to determine whether a valid activation request for the guarded critical button has been received; and
activating the guarded critical button only when it is determined that a valid activation request for the guarded critical button has been received.

-
displaying, using a first design, non-critical buttons; displaying, using a second design that is different than the first design, a guarded critical button, wherein the second design causes the guarded critical button to appear to have an overlaid object on it; rendering the guarded critical button as a third design that is different from the first design and different from the second design responsive to sensing a first touch input associated with the second design of the guarded critical button, wherein the third design causes the guarded critical button to appear to have the overlaid object partially removed; sensing second touch input associated with the third design of the guarded critical button; processing a combination of the first touch input and second touch input to determine whether a valid activation request for the guarded critical button has been received; and activating the guarded critical button only when it is determined that a valid activation request for the guarded critical button has been received. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A touch screen display system comprising:
-
a touch screen device configured to display a plurality of buttons and to sense touch input; and a processor operatively coupled to the touch screen device and adapted to receive activation criteria, the processor configured to (i) display, using a first design, non-critical buttons; (ii) display, using a second design that is different than the first design, a guarded critical button, wherein the second design causes the guarded critical button to appear to have an overlaid object on it; (iii) render the guarded critical button as a third design that is different from the first design and different from the second design in response to sensing a first touch input associated with the second design of the guarded critical button; (iv) sense a second touch input associated with the third design of the guarded critical button; (v) process a combination of the first touch input and second touch input to determine whether a valid activation request for the guarded critical button has been received; and (vi) activate the emergency action associated with the guarded critical button only when it is determined that a valid activation request for the guarded critical button has been received. - View Dependent Claims (17, 18)
