Abstract

A method and system for improving touch screen display use during vibration and turbulence conditions is provided. The system includes a sensor configured to transmit a first input signal relative to a measured parameter of the vehicle, a touch screen input and display system configured to transmit a second input signal relative to a manual input by a user. The touch screen input and display system includes a planar input and viewing surface having a plurality of edges and a bezel at least partially surrounding the surface proximate at least some of the plurality of edges. The bezel includes a surface configured to engage one or more digits of one or more hands of a user and is formed of an elastomeric material. The system also includes an input unit configured to receive the transmitted first and second input signals.

a surface configured to engage one or more fingers of one or more hands of a user, said surface formed of an elastomeric material; and

a second sensor configured to;

determine an anchor point represented by a number and placement of the one or more fingers on said surface of said bezel;

measure a motion of said one or more fingers relative to said bezel, said motion caused by at least one of vibration, shock, and turbulence; and

generate a third signal representing a magnitude and direction of said motion; and

an input unit configured to;

receive the first signal, the second signal, and the third signal; and

relocate or resize the touch activated area based on the first signal and the third signal to compensate for said motion of said one or more fingers caused by at least one of vibration, shock, and turbulence; and

adjust the second signal representing the manual input in a direction opposite said motion of said one or more fingers to compensate for said motion.

2. A system in accordance with claim 1, wherein said touch activated area is configured to receive a manual input from a finger, said touch activated area configured to be at least one of relocated and resized on said touch screen based on an input from a sensor configured to use at least one of capacitance, proximity, acceleration, force, and a combination thereof to determine the magnitude and direction of the motion of the user with respect to said touch screen due to at least one of vibration, shock, and turbulence.

3. A system in accordance with claim 1, wherein said bezel comprises at least one of a trough and a protrusion configured to engage one or more fingers of one or more hands of the user.

18. A system in accordance with claim 1, wherein said system is further configured to:

determine a position of the one or more hands of the user;

determine a placement of the one or more fingers of the user;

measure turbulence using the turbulence sensor; and

determine the unintended anchor point movement based on the position of the one or more hands, the placement of the one or more fingers, and the measured turbulence.

20. A system in accordance with claim 1, wherein said planar input and viewing surface is sized for use by a range of human anthropometric dimensions, and configured to permit two stabilized hands to touch thumbs proximate a center of said planar input and viewing surface.

4. A method of improving touch screen display use during vibration and turbulence conditions comprising:

landing at least one digit of at least one hand of a user on a bezel at least partially surrounding a touch screen input and display device, the bezel comprising at least one of a vibration, shock, and turbulence sensor;

engaging a touch activated area of the touch screen input and display device with at least one other finger of the at least one hand, thereby generating a touch input;

determining an anchor point represented by a number and placement of the at least one digit on the bezel;

determining a magnitude and direction of motion of the at least one digit and the anchor point relative to the bezel based on the output of the at least one of a vibration, shock, and turbulence sensor, wherein the motion is due to turbulence; and

adjusting the touch input in a direction opposite the anchor point movement based on the determined magnitude and direction.

5. A method in accordance with claim 4, wherein landing at least one flew digit of at least one hand of a user on a bezel comprises landing at least one finger of at least one hand of a user in a trough formed in a surface of the bezel and sized to receive the at least one finger.

6. A method in accordance with claim 5, wherein landing at least one finger of at least one hand of a user on a bezel comprises landing at least one finger of at least one hand of a user on a surface of protrusion extending from the trough, the protrusion formed of an elastomeric material.

7. A method in accordance with claim 4, wherein landing at least one digit of at least one hand of a user on a bezel comprises landing at least one finger of at least one hand of a user on a resilient surface of the bezel.

8. A method in accordance with claim 4, wherein landing at least one digit of at least one hand of a user on a bezel comprises landing at least one finger of at least one hand of a user on the bezel formed of elastomeric material.
