PRESENTATION SUPPORTING DEVICE, PRESENTATION SUPPORTING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A presentation supporting device extracts a first word from a character string included in each region divided from a page of a document file, and calculates a score, for each region in a page currently-displayed, based on the first word and a second word acquired as a result of a sound recognition, and calculates, when the highest score of scores is equal to or higher than a first threshold, a distance between a first region in which the highlight display is currently executed and a second region in which the highest score is equal to or higher than the first threshold, and executes a highlight display in the second region when a frequency corresponding to the distance between the first region and the second region is equal to or higher than a second threshold, and executes a highlight display in the first region, when the second threshold is not reached.

主权项

1. A presentation supporting device comprising:
a processor that executes a process comprising; extracting a first word from a character string included in each region divided from a page of a document file including the page displayed in a unit of a screen during a display; executing sound recognition; first calculating a score, with respect to each region in a page currently-displayed on a predetermined display device, based on the first word extracted from the region and a second word acquired as a result of the sound recognition; second calculating, when the highest score of the scores respectively-calculated for the regions is equal to or higher than a first threshold, a distance between a first region in which a highlight display is currently executed and a second region in which the highest score is equal to or higher than the first threshold; first determining to execute a highlight display in the second region when a frequency, which corresponds to the distance between the first region and the second region, among a frequency included in frequency data to which a distance between regions and a frequency of transition of a highlight display are associated is equal to or higher than a second threshold; and second determining to execute a highlight display in the first region, when the second threshold is not reached, until a frequency of the highest score becoming equal to or higher than the first threshold becomes equal to or higher than a third threshold.
