Wearable computer in a process control environment
First Claim
1. A wearable computer for use in a process environment having a process control system, comprising:
- a processing unit;
a computer readable memory coupled to the processing unit;
a display;
an input device that provides an input signal to the processing unit; and
one or more software routines stored in the computer readable memory and executable on the processing unit to process the input signal and provide process information pertaining to the process control system via the display based on the input signal;
wherein the input device is a microphone, the input signal is a speech signal and the one or more software routines includes a speech recognition routine that processes the speech signal to develop a user input.

Abstract
A wearable computer for use in a process control environment includes a central processing unit, a memory and a number of other or integral devices such as a display, a microphone, a video camera, a voice recognition unit and a remote communication device that communicates with a host computer. The wearable computer provide information pertaining to one or more devices within a process control system (such as diagnostic information, help information, operator overviews, schematics or process parameter information) via the display. The wearable computer also executes a voice recognition routine that processes a received voice signal to automatically identify user inputs such as commands, process control devices within the field of view of the wearer, device tags, etc. and uses the user inputs to change a display, to alter a process signal, to retrieve device information etc.

22. A wearable computer system for use in altering or testing a process control system, comprising:
-
a processing unit; a computer readable memory; an input device that develops an input signal in the form of a speech signal; a remote communication device that communicates with the process control system;
a voice recognition unit that processes the speech signal to decode the speech signal;
a software routine executable on the processing unit to use the decoded speech signal to develop a change signal indicating a change to be made in a parameter within the process control system and to communicate the change signal to the process control system via the remote communication device to thereby cause a change to be made to the process control system. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A process control communication unit for use in a wearable computer having a processor, a microphone that develops an input signal in the form of a speech signal, a display and a remote communication device that communicates with a process control system, the process control communication unit comprising:
-
a memory; a voice recognition unit that decodes the speech signal to develop a user input instruction; and a software routine stored on the memory and executable on the processor of the wearable computer to process the user input instruction to develop a change signal indicating a change to be made in a process signal within the process control system and to communicate the change signal to the process control system via the remote communication device to thereby cause the change to be made to the process signal. - View Dependent Claims (30, 31, 32, 33, 34)

35. A wearable computer comprising:
-
a processor; a microphone that produces a speech signal; a display; a computer readable memory; a voice recognition unit that processes speech signal to produce an input signal; a first software routine stored on the computer readable memory and executable on the processor to identify a process control device based on the input signal; a second software routine stored on the computer readable memory and executable on the processor to provide an indication via the display that a previously stored information signal is available for the identified process control device when the previously stored information signal exists for the identified process control device and that provides the previously stored information signal for the identified process control device in response to a second user input selecting the previously stored information signal for the identified process control device for retrieval. - View Dependent Claims (36, 37, 38, 39, 40)
