Abstract

A slide contents processor has a computer, a percentage computer and a categorizing unit. The computer computes a deviation of explanation time of each slide to total explanation time of slides. The percentage computer computes a percentage of objects in the slide based on the number of the objects by type in the slide. The categorizing unit categorizes the slide based on the deviation and the percentage.

Claims

1. A slide contents processor comprising:

a computer that computes a deviation of explanation time of each slide to total explanation time of slides;

a percentage computer that computes a percentage of objects in the slide based on the number of the objects by type in the slide; and

a categorizing unit that categorizes the slide based on the deviation and the percentage.

2. The slide contents processor according to claim 1, further comprising:

a display that generates information that arranges and displays contents of the slide by item categorized by the categorizing unit.

3. The slide contents processor according to claim 1, further comprising:

a recording unit that records explanation time of the slide.

4. The slide contents processor according to claim 1, further comprising:

a counter that counts the number of objects in the slide by object type.

5. The slide contents processor according to claim 1, wherein the categorizing unit computes a browse type and a score of the browse type and the score is importance of a slide in each browse type, the slide contents processor further comprises a slide structuring unit that creates a headline list and an article list based on the browse type and the score to structure the slide.

6. The slide contents processor according to claim 5, wherein the headline list includes only slides categorized as keyword.

7. The slide contents processor according to claim 5, wherein the article list includes slides categorized as keyword included in the headline list and only slides categorized as non-keyword included from the slide categorized as keyword to a next slide categorized as keyword.

8. The slide contents processor according to claim 5, wherein the article list lists slides in descending order in accordance with scores in a browse type.

9. The slide contents processor according to claim 5, wherein the slide structuring unit links a slide categorized as keyword included in the headline list to a list of slides categorized as non-keyword included between keywords included in the article list to generate a two-dimensional list.

10. The slide contents processor according to claim 4, wherein the object type includes at least any one of a text object, an image object, and a graphics object.

11. The slide contents processor according to claim 1, wherein the percentage computer categorizes the slide as one of a text object and a non-text object to compute the percentage of objects in the slide.

12. The slide contents processor according to claim 1, wherein the categorizing unit categorizes the slide as at least any one of browsing, careful reading, intent listening, and keyword.

13. The slide contents processor according to claim 1, wherein the categorizing unit assigns the deviation of explanation time of each slide computed by the computer in a manner that with an origin of 50, a high deviation is assigned in a positive direction and a low deviation is assigned in a negative direction, computes a difference between the percentage of text objects and the percentage of non-text objects of the slide computed by the percentage computer, and assigns, with an origin of 0, a text object to one pole and a non-text object to another pole.

14. The slide contents processor according to claim 13, wherein the categorizing unit categorizes, in the slide, to four quadrants of a two-dimensional plane constituted of two axes of the deviation of explanation time of the slide and the percentage of objects in the slide, a quadrant in which the deviation of explanation time is positive seen from the origin and the percentage of objects in the slide belongs to text as careful reading, a quadrant in which the deviation of explanation time is positive seen from the origin and the percentage of objects in the slide belongs to non-text as intent listening, a quadrant in which the deviation of explanation time is negative seen from the origin and the percentage of objects in the slide belongs to text as keyword, or a quadrant in which the deviation of explanation time is negative seen from the origin and the percentage of objects in the slide belongs to non-text as browsing.

15. The slide contents processor according to claim 2, wherein the display includes a correcting unit that performs change of a layout, addition display of a slide, and addition display of a summary of the contents to the slide in accordance with a screen size of the display device.

16. The slide contents processor according to claim 2, wherein the display displays a headline of an item categorized by the categorizing unit.

17. The slide contents processor according to claim 16, wherein the headline of the item includes at least any one of browsing, careful reading, intent listening, and keyword.

18. The slide contents processor according to claim 2, wherein the contents of the slide includes at least one of a reduced image of the slide and a title of the slide.

19. A slide contents processing method comprising:

computing a deviation of explanation time of each slide to total explanation time of slides;

computing a percentage of objects in the slide based on the number of objects by type in the slide; and

categorizing the slide based on the deviation of explanation time of the slide and the percentage of objects in the slide.

20. The slide contents processing method according to claim 19, further comprising generating information that arranges and displays contents of the slide by item categorized by the categorizing.

21. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function comprising:

computing a deviation of explanation time of each slide to total explanation time of slides;

computing a percentage of objects in the slide based on the number of objects by type in the slide; and

categorizing the slide based on the deviation of explanation time of the slide and the percentage of objects in the slide.

22. The storage medium readable by a computer, the storage medium storing a program according to claim 21, which further allows the computer to execute generating information that arranges and displays the contents of the slide by item categorized by the categorizing.

23. A slide contents processor comprising:

a computer that computes a slide;

a categorizing unit that categorizes in the slide, to four quadrants of a two-dimensional plane constituted of two axes based on a result computed by the computer.
