:: Overview of the system ::

The Figure below illustrates iPad interface. It consists of 5 parts: Document Editor frame, Insert Tag frame, Document Browser frame, Tool bar, and Message bar.

  1. Documents (i.e., notes, reports, etc.) are displayed and edited in the Document Editor frame.
  2. A user can insert a tag into a document by clicking on the desired tag in the Insert Tag frame, and the tag will be inserted at the position of the mouse cursor.

  5. The Message bar displays helpful messages and hints to the user.
