ABSTRACT:
A user is provided with guidelines that are temporarily displayed with content, in order to assist the user in neatly and accurately writing electronic ink. The guidelines may appear when the user moves a writing tool, such as a stylus or pen, close to a display and writing surface. Alternately, the guidelines may appear after the user has begun to write electronic ink, so that the guidelines can correspond to the angle at which the user is writing, the size of the user's handwriting, or both. As the user writes the electronic ink onto the writing surface, the handwritten electronic ink is added to the content being rendered on the display. After the user has finished writing electronic ink and moves the writing tool away from the writing surface, the guidelines are deleted, and are not added to the displayed content. In this way, the user can employ the temporary guidelines to accurately and legibly write electronic ink into content, without the guidelines themselves becoming a permanent part of the content.
