Information processing device, information processing method, program and storage medium for efficiently managing a browsing time of a window on a browser by another window

An information processing method executed by an information processing device, comprising:

• generating web page data of a first window including a program causing a terminal device to execute a first process for determining an elapsed time, the first process for determining an elapsed time comprising:
• obtaining first time information at a first timing of a first transition of focus from the first window to a second window;
• obtaining second time information at a second timing among a plurality of second timings during which a second process in the unfocused first window is executable in a state after the first transition to the focused second window;
• based on the focused second window maintaining focus after the first transition, calculating an elapsed time from a difference between the first time information and the second time information;
• and
• executing a predetermined third process according to a comparison between the calculated elapsed time and a threshold time;
• and
• prior to the first transition, executing a fourth process for transmitting the web page data to the terminal device and causing the terminal device to present the web page data in the first window that is in focus, wherein
• the first process for determining an elapsed time is executed on a browser in the terminal device, and
• specifications of the browser continuously allow processing in the focused second window, and allow processing in the unfocused first window only at the plurality of second timings,
• wherein the first process for determining an elapsed time further comprises, based on the second window being unfocused after the first transition and later being again focused according to a second transition of focus to the second window, calculating the elapsed time based on an addition of the following two periods:
• a first period starting from the timing of the first transition to a time when the second window becomes unfocused, and
• a second period starting from a timing of the second transition to a timing during which the second process in the first window is executable in a state after the second transition to the second window.

A non-transitory computer-readable storage medium that records a program, the program causing an information processing device to execute:

• a page generating function configured to generate web page data of a first window including a program causing a terminal device to execute a first process for determining an elapsed time, the first process for determining an elapsed time comprising:
• obtaining first time information at a first timing of a first transition of focus from the first window to a second window;
• obtaining second time information at a second timing among a plurality of second timings during which a second process in the unfocused first window is executable in a state after the first transition to the focused second window;
• based on the focused second window maintaining focus after the first transition, calculating an elapsed time from a difference between the first time information and the second time information;
• and
• executing a predetermined third process according to a comparison between the calculated elapsed time and a threshold time;
• and
• a presentation control function configured to, prior to the first transition, execute a fourth process for transmitting the web page data to the terminal device and causing the terminal device to present the web page data in the first window that is in focus, wherein
• the first process for determining an elapsed time is executed on a browser in the terminal device, and
• specifications of the browser continuously allow processing in the focused second window, and allow processing in the unfocused first window only at the plurality of second timings,
• wherein the first process for determining an elapsed time further comprises, based on the second window being unfocused after the first transition and later being again focused according to a second transition of focus to the second window, calculating the elapsed time based on an addition of the following two periods:
• a first period starting from the timing of the first transition to a time when the second window becomes unfocused, and
• a second period starting from a timing of the second transition to a timing during which the second process in the first window is executable in a state after the second transition to the second window.
