Abstract

A system and method are provided for employing an intelligent stencil mask to interact with a touch screen interface and thereby reduce the probability of accidental control function activation. A touch screen interface onboard an aircraft is coupled to a processor and is configured to generate a first virtual mask having a first region and a second region. A user interaction is then detected with one of the first region and the second region. A first reconfigured virtual mask is generated if the user interacted with the second region. However, an aircraft control function is activated if the user interacted with the first region.

Claims

1. A method for operating a touch screen interface, the method comprising:

generating a first virtual mask having a first region thereon;

generating a first reconfigured virtual mask in response to a user interaction with the first region;

generating a second region on the first reconfigured virtual mask that interacts with the first region of the first virtual mask;

detecting a user interaction with the first region of the first virtual mask;

generating a user interaction intentionality profile;

determining if a predefined characteristic of the user intentionality profile satisfies a predetermined criteria associated with a predefined intentionality profile;

detecting a user interaction with the second region of the first reconfigured virtual mask; and

generating a second reconfigured virtual mask in response to a user interaction with the second region of the first reconfigured virtual mask.

2. The method of claim 1 wherein the first region has a significance level greater than a threshold level.

3. The method of claim 2 further comprising:

detecting a user interaction with the first region;

generating a user interaction intentionality profile; and

comparing the user interaction intentionality profile with a predetermined user interaction

intentionality profile.

4. The method of claim 3 wherein the step of generating a user interaction intentionality profile, comprises:

separating the user interaction into a plurality of zones, each having an associated amplitude; and

weighting the amplitudes of the plurality of zones.

5. The method of claim 3 further comprising:

rejecting the user interaction intentionality profile if a predefined characteristic of the user intentionality profile does not satisfy a predetermined criteria associated with a predefined intentionality profile; and

activating a control function associated with the first region if the user intentionality profile satisfies the predetermined criteria.

6. The method of claim 1 further comprising:

retrieving a significance level associated with a second region;

determining if the significance level of the second region is less than a threshold level; and

generating the second region on the first virtual mask.

7. The method of claim 6 further comprising:

detecting a user interaction with the second region; and

activating a control function in response to the user interaction.

8. A touch screen controller system onboard an aircraft, comprising:

a touch screen interface; and

a processor configured to (a) generate a first virtual mask on the touch screen interface having a first region thereon;

(b) generate a reconfigured virtual mask on the touch screen in response to detecting a user interaction with the first region;

(c) generate a second region on the first reconfigured virtual mask that interacts with the first region of the first virtual mask;

(d) detect a user interaction with the first region of the first virtual mask;

(e) generate a user interaction intentionality profile;

(f) determine if a predefined characteristic of the user intentionality profile satisfies a predetermined criteria associated with a predefined intentionality profile;

(g) detect a user interaction with the second region of the first reconfigured virtual mask; and

(h) generate a second reconfigured virtual mask in response to the user interaction with the second region of the first reconfigured virtual mask.

9. The system according to claim 8 wherein the processor is further configured to:

(i) reject the user interaction intentionality profile if a predefined characteristic of the user intentionality profile does not satisfy a predetermined criteria associated with the predefined intentionality profile; and

(j) activate a control function associated with the first region if the user intentionality profile satisfies the predetermined criteria.

10. The system according to claim 9 wherein the processor is further configured to:

(k) retrieving a significance level associated with a region;

(l) determine the associated significance level is less than a threshold level; and

(m) activate a control function in response to the user interaction with the second region.
