Description

Technical field [0001] The invention relates to the field of information display, and in particular to a method and device for adding comments to an electronic document. Background technique [0002] With the continuous promotion and popularization of e-readers, many people who like to read books use e-readers to read. Since the e-reader uses a bi-stable display screen with electronic ink technology, it allows users to read under strong light and consumes less power. [0003] Many people have the habit of writing notes when reading, even when using handheld electronic devices for reading. The notes on paper books are mostly located in the margins of the pages, and the correspondence between the main text and the notes is clear. However, handheld electronic devices are limited by the small size of the display screen. In order to display more content, the page margins are generally small, and it is difficult to provide enough space for users to add handwritten comments. At present...

Handheld electronic devices are limited by the small size of the display screen. In order to display more content, the page margins are generally small, and it is difficult to provide enough space for users to add handwritten annotations

At present, most handheld electronic devices that support handwritten annotations do not provide a dedicated space for users to add handwritten annotations. Users use a small amount of fixed space between lines or margins to make annotations in the document content display area. This method is more suitable for marking key paragraphs. However, it is not suitable for adding text and graphic annotations that require more space, and for documents with fluid typesetting, when the font, screen resolution and other conditions change, the typesetting changes accordingly, and the handwritten annotations added to the text cannot be located. exact location
