<p><P>PROBLEM TO BE SOLVED: To improve convenience by allowing systematic reading of a document recorded in electronic publications, in regard to a document display device. <P>SOLUTION: In the first execution mode of the document display device 1, a CPU 11 of the document display device 1 computes the reading speed on the basis of the number of characters of the document displayed in a screen and the time spent to read them per each time when page is turned by a reader. The CPU 11 obtains the necessary time to read a chapter, which the reader is presently reading, a following chapter and the whole of the document or the planned time estimated to finish reading, and displays it in a screen. In the second execution mode, the CPU 11 computes a get-on route and the get-on planned time on the basis of the information about get-on station, get-on time and get-off station appointed by the reader, and obtains a range of the document possible to be read within the get-on planned time, and displays it. The CPU 11 compares the reading speed of the reader with the speed necessary to read the predetermined range of the document within the get-on planned time, and displays a result of the comparison in the screen. <P>COPYRIGHT: (C)2004,JPO</p> |
