Abstract

According to one embodiment, an display processing apparatus includes an operation receiver, a relation calculator, a display information generator, a display controller, and a scrolling module. The operation receiver receives selection of a key content. The relation calculator calculates relation between the key content and each of second contents. The display information generator generates first display information of the key content and second display information of the second contents. The display controller displays list information in which pieces of the second display information are arranged to form concentric polygons around the first display information along directions of operation such that second display information of second content with higher relation is closer to the first display information. The scrolling module scrolls, in response to user operation, the list information. The display controller maintains the first display information in the display range.

Claims

1. A display processing apparatus including a processor, the display processing apparatus comprising:

an operation receiver configured to receive operation to select a key content as a search key;

a display information generator configured to generate display information indicating the key content and display information indicating other contents related to the key content;

a display controller configured to display list information including the display information of the key content at a predetermined position and pieces of the display information of the other contents, each piece of the display information of the other contents being arranged according to a relation of a corresponding piece of the display information of the other content; and

a scrolling module configured to scroll the list information in a predetermined display range,

wherein when an initial display position where the display information of the key content is initially displayed moves outside the display range, the display controller displays the display information of the key content with direction information indicating direction of the initial display position in the display range, and

the display controller is configured to display the direction information in different sizes depending on distance between the display information of the key content and the initial display position.

2. The display processing apparatus of claim 1, wherein

the display controller is configured to display the direction information in a substantially triangular shape with a corner pointing to the initial display position, and

the display controller is configured to display the direction information smaller as the distance between the display information of the key content and the initial display position increases.

3. The display processing apparatus of claim 1, further comprising a display module configured to display the display information of the key content and the display information of the other contents.

4. The display processing apparatus of claim 1, further comprising a relation calculator configured to calculate relation between the key content and the other contents, wherein

the display controller is configured to display the display information of the key content at the predetermined position and pieces of the display information of the other contents around the display information of the key content, the pieces of the display information of the other contents being arranged to form a plurality of concentric polygons with the display information of the key content as center along directions of operation on the input module such that display information of content with higher relation to the key content is closer to the center.

5. The display processing apparatus of claim 4, wherein the display controller is configured to display the display information of the key content in largest size, and display the pieces of the display information of the other contents smaller as distance from the center increases.

6. The display processing apparatus of claim 4, wherein the display controller is configured to display information of content specified through the input module larger than display information of other contents not specified.

7. The display processing apparatus of claim 4, further comprising a metadata acquiring module configured to acquire metadata of the key content and metadata of the other contents, wherein

the relation calculator is configured to calculate the relation between the key content and each of the other contents with respect to each of items contained in the metadata based on the metadata of the key content and the metadata of the other contents, and

the display controller is configured to display the list information divided into predetermined areas, each assigned one of the items, in radial directions from the center, the pieces of the display information of the other contents being arranged with respect to each of the items such that display information of content with higher relation to the key content is closer to the center.

8. The display processing apparatus of claim 7, wherein, when there is a change in number of the items in the display range due to scrolling by the scrolling module, the display controller changes display of the items according to the change.

9. The display processing apparatus of claim 8, wherein, when an item is removed from the display range due to scrolling by the scrolling module, the display controller does not display the item.

10. The display processing apparatus of claim 9, wherein, when an item is added to the display range due to scrolling by the scrolling module, the display controller additionally displays the item.

11. A display processing method comprising:

receiving operation to select a key content as a search key by an operation receiver;

generating display information indicating the key content and display information indicating other contents related to the key content by a display information generator;

displaying list information by a display controller, the display list information including the display information of the key content at a predetermined position and pieces of the display information of the other contents, each piece of the display information of the other contents being arranged according to a relation to the display information indicating the key content; and

scrolling the list information in a predetermined display range by a scrolling module,

wherein when an initial display position where the display information of the key content is initially displayed moves outside the display range, the display information of the key content is displayed with direction information indicating direction of the initial display position in the display range,

wherein the displaying includes

displaying the direction information in a substantially triangular shape with a corner pointing to the initial display position, and

displaying the direction information smaller as the distance between the display information of the key content and the initial display position increases.

12. A computer program product comprising a computer-readable storage medium having computer readable program codes embodied in the medium that, when executed, causes a computer to implement:

an operation receiver configured to receive operation to select a key content as a search key;

a display information generator configured to generate display information indicating the key content and display information indicating other contents related to the key content;

a display controller configured to display list information including the display information of the key content at a predetermined position and pieces of the display information of the other contents; and

a scrolling module configured to scroll the list information in a predetermined display range, wherein

when an initial display position where the display information of the key content is initially displayed moves outside the display range, the display controller displays the display information of the key content with direction information indicating direction of the initial display position in the display range,

the display controller is configured to display the direction information in a substantially triangular shape with a corner pointing to the initial display position, and

the display controller is configured to display the direction information smaller as the distance between the display information of the key content and the initial display position increases.
