Abstract

An information displaying apparatus includes a presentation displaying unit that displays presentation information on a display unit, a pointing-input receiving unit that receives a pointing to the display unit, a pointing-area detecting unit that detects a pointing area with respect to a predetermined coordinate area including the displayed presentation information, an attention-area determining unit that determines an attention area with respect to the presentation information based on the detected pointing area and an attention-area determination rule, and a highlight displaying unit that displays the determined attention area in a highlighting manner with respect to the presentation information.

Claims

1. An apparatus for displaying presentation information, comprising:

a presentation displaying unit that displays the presentation information on a display unit;

a pointing reception unit that receives a pointing to the display unit from a user;

a pointing-area detecting unit that detects a pointing area with respect to a predetermined coordinate area including the displayed presentation information;

a rule storing unit that stores an attention-area determination rule for specifying an attention area from the pointing area;

an attention-area determining unit that determines an attention area with respect to the presentation information based on the pointing area detected by the pointing-area detecting unit and the attention-area determination rule; and

a highlight displaying unit that displays the attention area determined by the attention-area determining unit in a highlighting manner with respect to the presentation information.

2. The apparatus according to claim 1, wherein the highlight displaying unit displays time-axis information indicating an elapse of time for which a presentation is performed, and displays the attention area determined by the attention-area determining unit in a highlighting manner in association with a time at which the presentation information is displayed in the time-axis information.

3. The apparatus according to claim 1, wherein the attention-area determining unit identifies a display area including the detected pointing area from display areas obtained by dividing the presentation information in a predetermined block, and determines the identified display area as the attention area.

4. The apparatus according to claim 3, wherein the attention-area determining unit identifies a line area including the detected pointing area from line areas obtained by dividing text information included in the presentation information in a block of line, and determines the identified line area as the attention area.

5. The apparatus according to claim 1, wherein

the attention-area determination rule includes a condition for the pointing area and a range of the attention area when satisfying the condition in association with each other, and

the attention-area determining unit determines the range of the attention area associated with the condition in the attention-area determination rule as the attention area, when the detected pointing area satisfies the condition.

6. The apparatus according to claim 1, further comprising:

an speech acquiring unit that acquires speech information from a voice of the user, wherein

the pointing-area detecting unit detects the pointing area based on the speech information acquired by the speech acquiring unit.

7. The apparatus according to claim 6, wherein the pointing-area detecting unit detects an area including a character string as the pointing area, when contents of the voice included in the speech information acquired by the speech acquiring unit agrees with the character string displayed as the presentation data.

8. The apparatus according to claim 1, wherein the highlight displaying unit displays a text or a figure included in the attention area in a zooming-in manner.

9. A method for displaying presentation information, comprising:

displaying the presentation information on a display unit;

receiving a pointing to the display unit from a user;

detecting a pointing area with respect to a predetermined coordinate area including the displayed presentation information;

determining an attention area with respect to the presentation information based on the detected pointing area and an attention-area determination rule stored in a rule storing unit; and

highlight-displaying the determined attention area in a highlighting manner with respect to the presentation information.

10. The method according to claim 9, wherein, in the highlight-displaying, time-axis information indicating an elapse of time for which a presentation is performed is displayed, and the attention area is displayed in a highlighting manner in association with a time at which the presentation information is displayed in the time-axis information.

11. The method according to claim 9, wherein, in the determining, a display area including the detected pointing area is identified from display areas obtained by dividing the presentation information in a predetermined block, and the identified display area is determined as the attention area.

12. The method according to claim 11, wherein, in the determining, a line area including the detected pointing area is identified from line areas obtained by dividing text information included in the presentation information in a block of line, and the identified line area is determined as the attention area.

13. The method according to claim 9, wherein

the attention-area determination rule includes a condition for the pointing area and a range of the attention area when satisfying the condition in association with each other, and

the range of the attention area associated with the condition in the attention-area determination rule is determined as the attention area in the determining, when the detected pointing area satisfies the condition.

14. A computer program product having a computer readable medium including programmed instructions for displaying presentation information, wherein the instructions, when executed by a computer, cause the computer to perform:

displaying the presentation information on a display unit;

receiving a pointing to the display unit from a user;

detecting a pointing area with respect to a predetermined coordinate area including the displayed presentation information;

determining an attention area with respect to the presentation information based on the detected pointing area and an attention-area determination rule; and

highlight-displaying the determined attention area in a highlighting manner with respect to the presentation information.

15. The computer program product according to claim 14, wherein, in the highlight-displaying, time-axis information indicating an elapse of time for which a presentation is performed is displayed, and the attention area is displayed in a highlighting manner in association with a time at which the presentation information is displayed in the time-axis information.

16. The computer program product according to claim 14, wherein, in the determining, a display area including the detected pointing area is identified from display areas obtained by dividing the presentation information in a predetermined block, and the identified display area is determined as the attention area.

17. The computer program product according to claim 14, wherein, in the determining, a line area including the detected pointing area is identified from line areas obtained by dividing text information included in the presentation information in a block of line, and the identified line area is determined as the attention area.

18. The computer program product according to claim 14, wherein

the attention-area determination rule includes a condition for the pointing area and a range of the attention area when satisfying the condition in association with each other, and

the range of the attention area associated with the condition in the attention-area determination rule is determined as the attention area in the determining, when the detected pointing area satisfies the condition.
