초록

The digital talking book allows the convenience of navigating through chapters or sections for the reading-disabled people. However, since bookmarks and notes which most eBooks use for their annotation systems offer the visual interfaces, it is difficult for visually impaired people to use them. This study proposes a mobile voice annotation system that can record and browse annotations by using only voice and hearing senses. Especially, this study developed a time positioning algorithm to decide the position of a voice annotation and also a search algorithm to find out a recorded voice annotation and the corresponding original context. Also, this study measured the accuracy of locating the exact position of a recorded annotation and verified the effectiveness of proposed algorithms by conducting an experiment on a prototype of the voice annotation system. The proposed system helps the disabled readers record their thoughts through mobile devices so as to improve the quality of life for visually impaired people.
