ページ間の行き来を伴う読みにおける紙と電子メディアの比較

抄録

This paper describes experiments to compare paper and electronic media in the reading with frequently moving back and forth between pages. In the first experiment, eighteen subjects read aloud multi-page documents with endnotes in three conditions:paper, a large display, and a small display. Results revealed that reading from paper was 6.8% faster than reading from the large computer display and 11.4%faster than reading from the smallcomputer display. No difference was found between scores of recognition tests of important words of documentsamong the three conditions. This indicates that paper is the most effective medium for people to read text speedily without preventing recollection of text documents. Detailed analyses of the reading process show that, in the paper condition, people perform both reading and page-turning simultaneously. On the other hand, when using computer displays, reading and turning pages were divided completely and performed separately. In the second experiment, twelve subjects read the same documents as the first one using electronic system with more effective features forpage-turning such as an overview of pages and links from reference symbols to notes. However, paper was still most efficient media to support reading with endnotes.
