PROBLEM TO BE SOLVED: To determine whether or not a content is browsed by a user.SOLUTION: A terminal executes the program associated with a content displayed in a window or the like of a browser that is operated in the terminal. By the execution of the program, the terminal registers a callback function, when the content is loaded in the window or the like, by the window.requestAnimationFrame method assigned to the window or the like. When the callback function is called, the terminal determines (S105) whether or not the window or the like is browsed by the user on the basis of intervals of time stamps (S101) of times when the callback function is called for the window or the like, and registers (S107) the callback function by the window.requestAnimationFrame method assigned to the window or the like. The terminal intermittently notifies (S106) a server of a result of the determination. |
