Abstract

Techniques for adjusting process variables in a process plant using gesture-based input on a user interface device include presenting a graphic representation associated with a process plant entity in the process plant and an indication of a process variable value corresponding to the process plant entity as measured with the actual process plant and providing a user control for receiving gesture-based input at a location on the user interface device corresponding to the graphic representation associated with the process plant entity to adjust the process variable value. In response to receiving gesture-based input from an operator to adjust the process variable value for the corresponding process plant entity, the user interface device presents an adjusted process variable value and sets the process variable in the actual process plant to the adjusted process variable value.

First claim

What is claimed is:

1. A method for adjusting process variables in a process plant entity via a user interface device, the method comprising:
presenting, by one or more processors, a process plant display including (i) a plurality of connected graphic representations associated with a plurality of process plant entities within a process plant and (ii) a process variable value for at least one process variable for a first process plant entity as measured within the process plant;
receiving, at the one or more processors, a single finger gesture-based input from a user at a location on the process plant display on a graphic representation associated with the first process plant entity and indicating an adjusted process variable value for the process variable, wherein the adjusted process variable value changes in proportion to an amount of time for the finger gesture-based input; and
in response to the finger gesture-based input from the user:
presenting, by the one or more processors, the adjusted process variable value for the process variable for the first process plant entity on the process plant display; and
setting, by the one or more processors, the process variable to the adjusted process variable value during on-line operation of the process plant, wherein a control module controls a field device associated with the first process plant entity to set the process variable to the adjusted process variable value.

2. The method of claim 1 , further comprising:
receiving, by the one or more processors, multi-gesture input from the user for at least two locations on the process plant display corresponding to at least two of the plurality of graphic representations associated with the plurality of process plant entities indicating, for each of the process variables corresponding to the at least two graphic representations, an adjusted process variable value; and
in response to the multi-gesture input from the user:
presenting, by the one or more processors, the adjusted process variable value for each of the process variables corresponding to the at least two graphic representations on the process plant display; and
setting, by the one or more processors, each of the process variables corresponding to the at least two graphic representations to the adjusted process variable value during on-line operation of the process plant.

3. The method of claim 1 , wherein when the process variable value is adjusted by more than a predetermined threshold amount based on the corresponding finger gesture-based input, the method further comprises:
providing, by the one or more processors, haptic feedback to the user including vibration of the process plant display, wherein an amount of haptic feedback increases as the adjustment to the process variable value increases.

4. The method of claim 1 , wherein the finger gesture-based input does not include physical contact by the user with the process plant display and the finger gesture-based input is received via one or more cameras communicating with the one or more processors.

5. The method of claim 1 , further comprising:
in response to the finger gesture-based input from the user, presenting, by the one or more processors, an adjusted graphic representation associated with the first process plant entity corresponding to the adjusted process variable value.

6. The method of claim 5 , wherein the first process plant entity is a tank, the process variable is a tank level, the graphic representation associated with the tank includes a graphic indication of the tank level within the tank, and when the user performs a swipe gesture corresponding to the tank level on the process plant display, the method comprises:
determining, by the one or more processors, a new tank level value based on the swipe gesture;
adjusting, by the one or more processors, the graphic indication of the tank level and a tank level value corresponding to the tank level on the process plant display to the new tank level value; and
setting, by the one or more processors, the tank level during on-line operation of the process plant to the new tank level value.

7. The method of claim 6 , wherein the new tank level value is determined based on a length and speed of the swipe gesture.

8. The method of claim 1 , further comprising:
locking, by the one or more processors, the process variable on the process plant display so that the process variable value for the process variable does not change in response to the finger gesture-based input.

9. The method of claim 1 , wherein the finger gesture-based input is at least one of: a tap gesture, a press gesture, a flick gesture, a drag gesture, a pinch gesture, or a spread gesture.

10. A user interface device for adjusting process variables in a process plant, the user interface device including:
a display screen;
one or more processors coupled to the display screen; and
a non-transitory computer-readable medium coupled to the one or more processors and storing instructions thereon, that when executed by the one or more processors, cause the operative interface device to:
display, via the display screen, a plurality of connected graphic representations associated with a plurality of process plant entities within the process plant and a process variable value for at least one process variable for a first process plant entity as measured within the process plant;
provide a user control overlaying a graphic representation for receiving a single finger gesture-based input from a user indicating an adjusted process variable value for the process variable, wherein the adjusted process variable value changes in proportion to an amount of time for the finger gesture-based input; and
in response to receiving the finger gesture-based input from the user via the user control:
display, via the display screen, the adjusted process variable value in the graphic representation; and
set, via a control unit, the process variable to the adjusted process variable value during on-line operation of the process plant, wherein a control module controls a field device associated with the first process plant entity to set the process variable to the adjusted process variable value.

11. The user interface device of claim 10 , wherein the instructions further cause the user interface device to:
provide a plurality of user controls, each user control overlaying the graphic representation for receiving finger gesture-based input from the user,
wherein when the plurality of user controls receives multi-gesture input from the user for at least two locations on the user interface corresponding to at least two of the plurality of graphic representations associated with the plurality of process plant entities indicating, for each of the process variables corresponding to the at least two graphic representations, an adjusted process variable value, the instructions cause the user interface device to display the adjusted process variable value for each of the process variables corresponding to the at least two graphic representations on the process plant display and set each of the process variables corresponding to the at least two graphic representations to the adjusted process variable value during on-line operation of the process plant.

12. The user interface device of claim 10 , wherein when the process variable value is adjusted by more than a predetermined threshold amount based on the corresponding finger gesture-based input, the instructions cause the user interface device to provide haptic feedback to the user, wherein an amount of haptic feedback increases as the adjustment to the process variable value increases.
