Patent ID: 8707202

Claim:
An information-processing device comprising: a control means for controlling display of at least one window on a display means, wherein each window corresponds to an application or a file; a measuring means for measuring a length of time of simultaneous display of two windows, wherein: the measuring means measures a first length of time of first simultaneous display of a first window and a second window; the first simultaneous display occurs when the first window is displayed while the second window is displayed, or when the second window is displayed while the first window is displayed; the measuring of the first length of time begins upon the first simultaneous display; the measuring means measures a second length of time of second simultaneous display of the first window and a third window; the second simultaneous display occurs when the first window is displayed while the third window is displayed, or when the third window is displayed while the first window is displayed; and the measuring of the second length of time begins upon the second simultaneous display; a storage control means for storing data in a table, wherein: the storage control means stores in the table, data on the first length of time in association with the first window and the second window; and the storage control means stores in the table, data on the second length of time in association with the first window and the third window; a receiving means for receiving an instruction to start display of the first window in a situation where the first to third windows are not displayed; and an identifying means, when the instruction is received by the receiving means, for comparing the first length of time associated with the first window in the table and the second length of time associated with the first window in the table to identify either the second or third window which is associated with a longer length of time in the table, or for comparing a rate calculated based on the first length of time and a rate calculated based on the second length of time to identify either the second or third window which is associated in the table with a length of time based on which a larger rate is calculated, wherein the control means displays the first window and the window identified by the identifying means.
