1. A wearable computing device comprising:
an image sensor for capturing still images and video;
a sensor for capturing spoken commands and audible sound;
a speaker;
a head-mounted display;
at least one processor; and
a memory storage device for storing instructions, which, when executed by the processor, cause the wearable computing device to perform operations comprising:
authenticating an end-user by scanning, with the image sensor, a symbol or code presented by the end-user;
subsequent to authenticating the end-user, selecting for presentation to the end-user via the head-mounted display a subset of electronic documents, each electronic document in the subset of electronic documents associated with a specific item of equipment on which the end-user is authorized to perform maintenance procedures;
upon detecting selection of an electronic document in the subset of electronic documents, presenting, via the head-mounted display within a first portion of a user interface the electronic document containing a combination of illustrations and text describing a maintenance procedure for a particular piece of equipment, the electronic document augmented with a workflow consisting of a plurality of interactive checklist items, each interactive checklist item displayed within the electronic document positioned proximate to some portion of illustrations or text associated with one or more tasks to be completed by an end-user for completing the maintenance procedure described in the electronic document and including a symbol that conveys a status of the one or more tasks as complete or incomplete;
upon receiving, via a wired or wireless connection, digital information from a tool or measuring device that is at least temporarily communicatively coupled to the wearable computing device, wherein the digital information represents a measurement reading or value obtained by the tool or measuring device and indicates completion of one or more tasks associated with a particular checklist item, storing the received digital information in association with the particular checklist item; and
updating the particular checklist item as presented in the first portion of the user interface by modifying the symbol included with the particular checklist item to reflect that the one or more tasks associated with the particular checklist item have been completed by the end-user based on the received digital information.
