A computing apparatus, includes a first apparatus and a second apparatus, a differential transmission line that couples the first apparatus and the second apparatus to each other, a noise application unit that applies noise to the differential transmission line, a noise control unit that controls the noise application unit, and a margin measurement unit that measures an occurrence frequency of communication error between the first apparatus and the second apparatus.

Computing apparatus and margin measurement method

The work support device stores information indicating a work order for each process, and information indicating a work area of a worker for each work in the process. A processor executes a specifying processing in which a target work to be performed by the worker is specified based on the information indicating the work order, a selection processing in which a target area where the target work specified by the specifying processing to be performed by the worker is selected based on the information indicating the work area, an identification processing in which a work performed by the worker is identified based on image data from a camera that captures an image of the area selected by the selection processing, a determination processing in which whether the worker has deviated from the work order is determined based on an identification result by the identification processing.
