Abstract: A method is provided for placing a first content and a second content on a display screen at a distance D along a Y-axis in an orthogonal coordinate system formed by an X-axis and the Y-axis. The method includes identifying, in the first content, a first non-display-target region which is located on the second content side, identifying, in the second content, a second non-display-target region which is located on the first content side, calculating a plurality of total widths each of which is a sum of a width of the first non-display-target region in a direction of the Y-axis and a width of the second non-display-target region in the direction of the Y-axis, the widths being at a same X-coordinate, and determining the distance D based on the plurality of total widths and a predetermined reference.

Abstract: The disclosed technique provides a non-transitory computer-readable medium storing a book display program which causes a computer to execute instructions comprising: receiving a command to change a display image of a virtual book displayed on a display unit from an operator, the book including a content; generating display control information to be applied to the display unit and used to control transition of the display image of the book; and three-dimensionally or two-dimensionally displaying the book based on the display control information. The generating display control information includes: obtaining a display state of the book; and selecting one of command conversion rules based on at least the display state, the one command conversion rule selected to be applied to the received command and used to generate the display control information.
