PROGRAMMABLE DISPLAY, MOBILE TERMINAL DEVICE, DATA PROCESSING METHOD, AND PROGRAM

摘要

A programmable display device (300) connectable to a programmable logic controller (100) in a communicable manner includes a sightline estimate unit (356), which estimates a direction of a sightline using image data obtained by capturing an image of a person, a display control unit (355), which displays a screen including an object on a display, a measurement unit (358), which measures a time period for which the sightline is directed to the object when the sightline is determined to be directed to the object through the estimation, and a storage unit (350), which stores image identification information identifying the object and time information indicating the measured time period in association with each other. This allows a third person to determine a time period for which a user has gazed at an object.
