Abstract

An information processing device includes: an operation unit to receive a user'"'"'s operation; a first communication unit to perform communication with an external device; a first content acquisition unit to acquire first content generated in response to the user'"'"'s operation; a second content acquisition unit to acquire second content received from the external device; a content storage unit to store the first and second content in association with their respective acquisition times; a display; and a display control unit. The display control unit causes the display to: display a time axis as well as first and second display regions; display the first content at a position on the time axis indicating the time associated with the first content in the first display region; and displays the second content at a position on the time axis indicating the time associated with the second content in the second display region.

Claims

1. An information processing device comprising:

an operation unit to receive a user'"'"'s operation;

a first communication unit to perform communication with an external device;

a first content acquisition unit to acquire first content that is generated in response to the user'"'"'s operation received by the operation unit;

a second content acquisition unit to acquire second content that is received from the external device via the communication performed by the first communication unit;

a content storage unit to store therein the first content and the second content in association with their respective acquisition times when the first content and the second content are acquired;

a display; and

a display control unit to cause the display to;

display a time axis as well as a first display region and a second display region not overlapping with each other;

display the first content stored in the content storage unit at a position on the time axis indicating the time associated with the first content in the first display region; and

displays the second content stored in the content storage unit at a position on the time axis indicating the time associated with the second content in the second display region.

2. The information processing device according to claim 1, wherein the display control unit changes a ratio between a width of the first display region and a width of the second display region in response to a user'"'"'s operation received by the operation unit.

3. The information processing device according to claim 1, wherein

the second content acquisition unit acquires the second content that is image data configured of page units and including one or more pages, and acquires, via the communication performed by the first communication unit, page operation information indicating operation on the page performed on the external device, and

the content storage unit stores therein the time when the page operation information is acquired in association with the second content.

4. The information processing device according to claim 3, wherein the display control unit causes the display to display each page of the second content at a position on the time axis corresponding to the page operation information of the each page.

5. The information processing device according to claim 1, wherein

the display control unit causes the display to display, in response to a user'"'"'s operation received by the operation unit, an input screen to prompt the user to enter a pass code, and

the content storage unit stores therein encrypted content obtained by encrypting at least the second content among the first content and the second content using the pass code.

6. The information processing device according to claim 1, further comprising a second communication unit to perform communication via a network, wherein

the second communication unit transmits, to a first server, the first content and the second content stored in the content storage unit, and transmits, to a second server, positional information indicating a position on the network of the first content and the second content transmitted to the first server in association with time information.

7. The information processing device according to claim 1, further comprising a second communication unit to perform communication via a network, wherein

the second content acquisition unit acquires the second content from a server connected to the external device via the communication performed by the second communication unit.

8. The information processing device according to claim 1, wherein the display control unit changes the scale of the time axis in response to a user'"'"'s operation on the time axis received by the operation unit.

9. The information processing device according to claim 1, further comprising a voice acquisition unit to acquire a voice, wherein

the content storage unit stores therein the voice acquired by the voice acquisition unit in association with an acquisition start time and an acquisition end time.

10. A display control method performed by an information processing device, the method comprising:

receiving a user'"'"'s operation;

performing communication with an external device;

acquiring first content that is generated in response to the user'"'"'s operation received at the receiving;

acquiring second content that is received from the external device via the communication performed at the receiving;

storing, in a content storage unit of the information processing device, the first content and the second content in association with their respective acquisition times when the first content and the second content are acquired; and

causing a display of the information processing device to

display a time axis as well as a first display region and a second display region not overlapping with each other,

display the first content stored in the content storage unit at a position on the time axis indicating the time associated with the first content in the first display region, and

display the second content stored in the content storage unit at a position on the time axis indicating the time associated with the second content in the second display region.

11. The display control method according to claim 10, wherein the causing includes changing a ratio between a width of the first display region and a width of the second display region in response to a user'"'"'s operation received at the receiving.

12. The display control method according to claim 10, wherein

the acquiring of the second content includes acquiring the second content that is image data configured of page units and including one or more pages, and acquiring, via the communication performed at the performing, page operation information indicating operation on the page performed on the external device, and

the storing includes storing, in the content storage unit, the time when the page operation information is acquired in association with the second content.

13. The display control method according to claim 12, wherein the causing includes causing the display to display each page of the second content at a position on the time axis corresponding to the page operation information of the each page.

14. The display control method according to claim 10, wherein

the causing includes causing the display to display, in response to a user'"'"'s operation received at the receiving, an input screen to prompt the user to enter a pass code, and

the storing includes storing, in the content storage unit, encrypted content obtained by encrypting at least the second content among the first content and the second content using the pass code.

15. The display control method according to claim 10, further comprising performing network communication via a network, wherein

the performing of the network communication includes transmitting, to a first server, the first content and the second content stored in the content storage unit, and transmitting, to a second server, positional information indicating a position on the network of the first content and the second content transmitted to the first server in association with time information.

16. The display control method according to claim 10, further comprising performing network communication via a network, wherein
