1. A method for determining a position of a mobile device within a process control environment, the method including:
- acquiring data indicating an anchor position within a process plant, wherein acquiring data comprises interacting with a context device in the process plant, the context device is related to a portion of the process plant;
determining the anchor position according to the acquired data;
receiving, from circuitry of the mobile device, data indicative of acceleration and orientation of the mobile device;
determining a position of the mobile device according to the received data and the anchor position;
determining a proximate device according to the determined position;
communicating the determined position of the mobile device to a control system of the process plant;
identifying a work item including a task to be performed by a person on the proximate device;
in response to identifying the work item, automatically launching an application of the mobile device;
wherein automatically launching the application includes generating and displaying a user interface element, on a display of the mobile device, that corresponds to the identified work item relating to the proximate device; and
altering a parameter of the process plant according to the determined position of the mobile device in the process plant.

Abstract
Methods, systems, and apparatus for determining with dead reckoning the position, relative to an anchor point, of a mobile device. Data indicating an anchor position within a process plant is acquired and an anchor position is determined according to the acquired data. Data indicative of acceleration and orientation of the mobile device are received from circuitry of the mobile device. A position of the mobile device is determined according to the received data and the anchor position.

16. A mobile device for performing control operations in a process control environment, the mobile device including:
-
a first circuit for acquiring first data indicating an anchor position within a process plant, wherein the first data comprises data indicative of an interaction with a context device; a second circuit for detecting acceleration and orientation of the mobile device, wherein the second circuit generates second data indicative of said acceleration and said orientation; and one or more processors, including at least one processor communicatively connected to the first circuit and at least one processor communicatively connected to the second circuit, operable to; (i) determine the anchor position based on the first data; (ii) determine a position of the mobile device according to the second data and the anchor position; (iii) determine a proximate device according to the position; (iii) communicate the determined position of the mobile device to a control system of the process plant; (iv) identify a work item including a task to be performed by a person on the proximate device; (v) in response to identifying the work item, automatically launch an application of the mobile device; wherein automatically launching the application includes generating and displaying a user interface element, on a display of the mobile device, that corresponds to the identified work item relating to the proximate device; and (vi) alter a parameter of the process plant according to the determined position of the mobile device in the process plant. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
