Abstract

A system for indexing displayed elements that is useful for accessing and understanding new or difficult materials, in which a user highlights unknown words or characters or other displayed elements encountered while viewing displayed materials. In a language learning application, the system displays the meaning of a word in context; and the user may include the word in a personal vocabulary to build a database of words and phrases. In a Japanese language application, one or more Japanese language books are read on an electronic display. Readings (‘yomi’) for all words are readily viewable for any selected word or phrase, as well as an English reference to the selected word or phrase. Extensive notes are provided for difficult phrases and words not normally found in a dictionary. A unique indexing scheme allows word-by-word access to any of several external multi-media references.
