Conventionally, in application software running on a computer, there are cases in which input of parameters for command instructions for processing, input or changes of properties, or the like are accepted. As a result, pop-up menus are used in many cases as one type of user interface.
For pop-up menus, a screen is displayed in response to, for example, a right-click of a mouse operated by a user, and by selection of a processing item from a displayed list, a corresponding process is executed. At that time, in a case where parameter input is required, a dialog box provided for this purpose is displayed, and input is accepted while execution of processing is triggered by pressing of the “run” button or the like provided in the dialog box.
Here, in application software, the more functions provided, the more processing items are displayed in pop-up menus, so it can also be considered that, for a user, an amount of time to search for a desired processing item increases.
Therefore, a method is proposed for improving a user interface with this kind of possibility of reducing convenience. For example, in Patent Document 1, a method is disclosed in which, by enabling effective display of a shortcut menu (pop-up menu) composed of a plurality of (many) levels, operability of the shortcut menu is increased, and it becomes possible for a user to carry out the user's desired processes more quickly.
