TK3 Author is a set of powerful, flexible tools that allows users to assemble text, images, sounds, and video into sophisticated interactive documents. It has been used to create educational projects, reference guides, ebooks, catalogues, and other dynamic presentations. TK3 Reader allows users to read multimedia documents created with TK3 Author. Unlike other kinds of electronic readers, TK3 Reader allows users to annotate and personalize TK3 books in many ways - highlight book passages, write notes on “stickies” that stay on the page, and copy text or other materials into a personal notebook. |
