Patent ID: 7230582

Claim:
A wearable computer for use in a process control environment having a process control system including a plurality of process control devices disposed within the process, the wearable computer comprising: a processing unit; a memory; an imaging device that produces an image signal; an image processor that processes the image signal to identify one of the devices based on a device feature identified by the image signal; a software routine stored in the memory which when executed on the processing unit provides process information generated by one or more of the plurality of process control devices during operation of the process; an input device adapted to produce an input signal; a remote communication device that communicates with the process control system; and a further software routine run on the processing unit that processes the input signal to develop a change signal indicating a change to be made in a process signal within the process control system and that communicates the change signal to the process control system via the remote communication device to thereby cause a change to be made to the process signal, where the process signal indicates a characteristic of the process during normal operation of the process.
