Work Instructions


Work Instructions are checklists or procedures, created during system design, to support the system’s entire life cycle:  assembly, test, inspection, operation, maintenance, repair and emergency operations. They can range in complexity from a simple checklist for a ball valve to a nuclear reactor plant manual, and they are used by such key personnel as assembly mechanics, technicians in field maintenance or field service, inspection engineers and electricians.

Work instructions are moving from paper manuals to digital formats, and efforts have been made to move them to PCs and tablets in order to streamline updates and improve worker productivity. But these implementations have often fallen short.

Digital Work Instructions: Challenges

  • Operating PCs and tablets requires removing gloves and occupies the hands, slowing the actual manual work
  • Consumer devices are unreliable in harsh field conditions
  • Screens can’t be read outdoors
  • Proximity of work instructions view to the work itself

with a Head-Mounted Tablet

An industrial head mounted tablet addresses all these challenges. Driven by noise-robust voice recognition, it is 100% hands free.  The worker can select the required instructions, navigate through them step by step with voice commands, and view text and images, video clips, diagrams, animations and 3D models. With a boom arm mounted display, the job and the instructions are in the same field of view at all times.
