Abstract: In asynchronous processing, processing of a low-order system is checked. A high-order system 1 includes a high-order workflow advancing unit 21 that transmits a processing command for asynchronous processing to a low-order system 2, and a notice processing unit 23 that receives, from the low-order system 2, a notice related to a device command to be executed by a device 3 in the asynchronous processing, and updates progress data 13. The low-order system 2 includes a low-order workflow advancing unit 61 that, upon receiving the processing command from the high-order system 1, transmits a device command to the device, and a notification unit 62 that, when transmission of the device command to the device 3 is detected, notifies the high-order system 1 of the identifier of the device to which the device command was transmitted and the device command.

Abstract: A display system is constituted of a smartphone and an HMD that are connected to each other. The HMD is mounted on a head of a user, and includes an image display unit configured to display an image, a reception unit configured to receive the image from the smartphone, and a first display controller configured to divide the image at a set division position, generate a plurality of divided images, and cause the image display unit to display each of the divided images. Further, the smartphone includes a transmission unit configured to transmit, to the HMD, image data corresponding to the image, and a second display controller configured to separate a position of an adjustment object away from a position corresponding to the division position in a case where the image includes the adjustment object for adjusting the image.
