US Patent 9477888 Providing computer-based instructions without displays

Computer-based instructions for performing a task may be provided to workers using system components that display such instructions in a convenient manner and location that permit the workers to perform the task without diverting their attention from their workstations. Such instructions may be projected onto all or a portion of a surface of the workstation, or onto a lens or other optical element of a wearable computer device, thereby enabling the worker to maintain his or her focus on the task at hand, rather than having to look away at a mounted computer monitor or printed text in order to receive the instructions.
