Information processing system, host device, storage media, and computer-implemented method

A host device comprising:

• processing circuitry;
• and
• one or more memories configured to store computer-executable instructions that cause the processing circuitry to perform processing comprising:
• acquiring first operation data indicating an operation performed on the host device;
• receiving, from a guest device, second operation data indicating an operation performed on the guest device;
• generating at least one image based on the first operation data and the second operation data;
• causing the host device to display a first image of the at least one image on a display device in accordance with an image switching timing at the host device,;
• and
• causing the host device to transmit a second image of the at least one image without waiting for the image switching timing.

A computer-implemented method, comprising:

• acquiring first operation data indicating an operation performed on the host device;
• on a host device, receiving, from a guest device, second operation data indicating an operation performed on the guest device;
• generating at least one image based on the first operation data and the second operation data;
• displaying a first image of the at least one image on a display device relating to the host device, in accordance with an image switching timing at the host device;
• and
• transmitting a second image of the at least one image from the host device to the guest device without waiting for the image switching timing;
• and
• on the guest device, receiving the second image transmitted from the host device;
• displaying the received second image on a display device relating to the guest device, in accordance with an image switching timing on the guest device;
• acquiring the second operation data of the guest device;
• and
• transmitting the second operation data to the host device.
