Abstract

A display control device including: an input control unit which receives a scrolling start indication and a scrolling stop indication from a user; a scrolling control unit which, if the scrolling stop indication is received, decelerates a scroll rate by a predetermined function and pre-calculates a location of a displayed area when the scrolling of the displayed area stops; and a focus control unit which superimposes a focus on an object closest to a predetermined position within the displayed area at any time from when the location of the displayed area when the scrolling stops is determined to when the scrolling stops, the focus representing that the object is being selected.

Claims

1. A display control device for displaying a displayed area on a display screen, the displayed area being a portion of content including a plurality of objects respectively associated with predetermined processes, the display control device comprising:

an instruction receiving unit configured to receive, from a user, a scrolling start indication for starting scrolling of the displayed area which is a process of sliding the displayed area on the content, and a scrolling stop indication for stopping the scrolling;

a scrolling control unit configured to decelerate a scroll rate by a predetermined function and pre-calculate a location of the displayed area when the scrolling stops, if the instruction receiving unit receives the scrolling stop indication during the scrolling; and

a focus control unit configured to superimpose a focus on an object, among the plurality of objects, that is closest to a predetermined position within the displayed area, at any time from when the scrolling control unit determines the location of the displayed area when the scrolling stops to when the scrolling stops, the focus representing that the object is being selected.

2. The display control device according to claim 1,

wherein the focus control unit is configured to display the focus at an edge of the display screen at any time from when the scrolling control unit determines the location of the displayed area when the scrolling stops to when the scrolling stops, and gradually bring the focus to the object so that the focus is superimposed on the object when the scrolling stops.

3. The display control device according to 2,

wherein when the instruction receiving unit receives the scrolling start indication, the scrolling control unit is configured to start the scrolling and gradually accelerate a scroll rate to a predetermined rate.

4. The display control device according to claim 3,

wherein the instruction receiving unit is configured to receive the scrolling start indication by the user depressing and holding a directional key on an operating device for a predetermined time period, and receive the scrolling stop indication by the user releasing the directional key, and

the scrolling control unit is configured to scroll the displayed area in a direction indicated by the directional key.

5. The display control device according to claim 4,

wherein the instruction receiving unit is further configured to receive a focus movement indication for moving the focus, by the user depressing the directional key for less than the predetermined time period, and

if the instruction receiving unit receives the focus movement indication, the focus control unit is configured to move the focus from, among a plurality of objects included in the displayed area, a first object currently having the focus superimposed thereon to a second object adjacent to the first object in a direction indicated by the directional key.

6. The display control device according to claim 1,

wherein the predetermined position is a center of the displayed area.

7. A display control method for displaying a displayed area on a display screen, the displayed area being a portion of content including a plurality of objects respectively associated with predetermined processes, the display control method comprising:

(a) receiving, from a user, a scrolling start indication for starting scrolling of the displayed area which is a process of sliding the displayed area on the content, and a scrolling stop indication for stopping the scrolling;

(b) decelerating a scroll rate by a predetermined function and pre-calculating a location of the displayed area when the scrolling stops, if the scrolling stop indication is received during the scrolling in step (a); and

(c) superimposing a focus on an object, among the plurality of objects, that is closest to a predetermined position within the displayed area, at any time from when the location of the displayed area when the scrolling stops is determined in step (b) to when the scrolling stops, the focus representing that the object is being selected.
