A head mount display comprising:

• a display;
• a communication interface configured to communicate with an information device;
• a camera for capturing an image of a front view including a visual field of a wearer of the head mount display to generate a front image;
• and
• a processing circuit,
• wherein the processing circuit is configured to:
• receive content data including text data associated with a plurality of processes from the information device via the communication interface,
• control the display to display the text data associated with one of the plurality of processes within a predetermined area of a virtual screen, and
• in response to determining that a state of a subject in the front image generated by the camera is included in a next process of the one of the plurality of processes, update the text data being displayed on the display and cause the display to display another text data associated with the next process.

A head mount display comprising:

• a display;
• a communication interface configured to communicate with an information device;
• a line-of-sight detection sensor configured to detect a line-of-sight of a wearer of the head mount display;
• and
• a processing circuit,
• wherein the processing circuit is configured to:
• receive content data including text data associated with a plurality of processes from the information device via the communication interface,
• control the display to display the text data associated with one of the plurality of processes and a virtual object within a predetermined area of a virtual screen, and
• in response to determining that the line-of-sight of the wearer detected by the line-of-sight detection sensor has stayed for a predetermined time on a virtual reality object, update the text data being displayed on the display and cause the display to display another text data associated with a next process.
