Abstract

A method is provided for avionic touchscreen operation. The method includes the steps of displaying one or more user input devices on a touchscreen panel, receiving user inputs on a face of the touchscreen panel, and generating input signals in response to the user inputs. The method further includes the steps of generating operational signals in response to comparing the input signals to predetermined user input signals, adjusting one or more avionic operation parameters in response to the operational signals, and providing user sensible outputs in response to the operational signals and in accordance with the user inputs. The step of providing user sensible output includes providing two or more user sensible outputs selected from the group of providing user sensible outputs including providing visual outputs, providing audible outputs and providing tactile outputs. Alternatively, the one or more user input devices displayed on the touchscreen panel includes one or more knobs.

Claims

1. A method for avionic touchscreen operation, the method comprising the steps of:

displaying one or more user input devices on a touchscreen panel, the one or more user input devices including a knob;

receiving user inputs on a face of the touchscreen panel that correspond to rotating the knob at a rotational speed;

generating input signals in response to the user inputs;

generating operational signals in response to comparing the input signals to predetermined user input signals;

adjusting one or more avionic operation parameters in response to the operational signals; and

providing two or more user sensible outputs in response to the operational signals and in accordance with the user inputs, wherein the step of providing two or more user sensible outputs comprises providing two or more user sensible outputs selected from the group of providing user sensible outputs including providing visual outputs, providing audible outputs and providing tactile outputs by vibrating the touchscreen panel at an amplitude and at a frequency, wherein the frequency varies in accordance with the rotational speed of the knob corresponding to the user inputs received.

2. The method in accordance with claim 1 wherein the step of providing visual outputs comprises the step of altering a visual appearance of the one or more user input devices displayed on the touchscreen panel in response to the operational signals by one or more of changing a size of at least one of the one or more user input devices in accordance with the user inputs, changing a color of at least one of the one or more user input devices in accordance with the user inputs, or changing a legend on at least one of the one or more user input devices in accordance with the user inputs.

3. The method in accordance with claim 1 wherein the step of providing audible outputs comprises the step of providing audio output signals to one or more of a flight crew headset or flight deck speaker system in response to the operational signals and in accordance with the user inputs.

4. The method in accordance with claim 3 wherein the knob is rotatable to one or more detents, and wherein the step of providing audible outputs in response to the operational signals comprises the step of providing an audible click having a predetermined amplitude to indicate the knob being rotated to one of the one or more detents in accordance with the user inputs corresponding to rotating the knob to the one of the one or more detents.

5. The method in accordance with claim 1 wherein the step of providing tactile outputs in response to the operational signals further comprises the step of providing a large amplitude bump to indicate the knob being rotated to one of the one or more detents in accordance with the user inputs corresponding to rotating the knob to the one of the one or more detents.

6. A method for touchscreen operation, the method comprising the steps of:

displaying one or more user input devices on a touchscreen panel, the one or more user input devices including a knob;

receiving user inputs on a face of the touchscreen panel that correspond to rotating the knob;

determining that the user inputs comprise an authenticated user input in response to determining that the user inputs are multitouch user inputs;

generating input signals in response to the authenticated user input;

generating operational signals in response to comparing the input signals to predetermined user input signals, the operational signals including selection of one of a coarse parameter adjustment or a fine parameter adjustment;

providing user sensible output in response to the operational signals and in accordance with the user inputs, the user sensible output comprising providing haptic feedback tactile outputs by selecting a first predetermined frequency and a first predetermined amplitude at which the touchscreen panel is vibrated in response to the coarse parameter adjustment or a second predetermined frequency and a second predetermined amplitude at which the touchscreen panel is vibrated in response to the fine parameter adjustment; and

adjusting one or more operational parameters in response to the operational signals.

7. The method in accordance with claim 6, wherein the method for touch screen operation comprises a method for avionic touchscreen operation, and wherein the step of displaying the one or more user input devices on the touchscreen panel comprises the step of displaying the one or more user input devices on the touchscreen panel in response to one of a crew input or a flight parameter, and wherein the step of adjusting one or more operation parameters comprises the step of adjusting one or more operation parameters in response to the operational signals and an engagement user input received separate from the user inputs and subsequent to the step of generating the operational signals.

8. The method in accordance with claim 6 wherein the step of receiving user inputs further comprises the step of receiving user input device arming inputs on the face of the touchscreen panel, and wherein the step of providing user sensible output comprises the step of providing visual output on the touchscreen panel in response to the operational signals, wherein the visual output comprises altering a legend on at least one of the one or more user input devices displayed on the touchscreen panel corresponding to the user input device arming inputs.

9. The method in accordance with claim 6 wherein the knob is rotatable to one or more detents, and wherein the step of providing haptic feedback tactile outputs in response to the operational signals includes the step of providing a large amplitude bump to indicate the knob being rotated to one of the one or more detents in accordance with the user inputs corresponding to rotating the knob to the one of the one or more detents.

10. The method in accordance with claim 9 wherein the step of providing user sensible output in response to the operational signals further comprises the step of providing an audible click having a predetermined amplitude to indicate the knob being rotated to one of the one or more detents in accordance with the user inputs corresponding to rotating the knob to the one of the one or more detents.
