Abstract: Various technologies and techniques are disclosed that improve the instructional nature of fonts and/or the ability to create instructional fonts. Font characters are modified based on user interaction to enhance the user's understanding and/or fluency of the word. The font characters can have sound, motion and altered appearance. When altering the appearance of the characters, the system operates on a set of control points associated with characters, changes the position of the characters, and changes the influence of the portion of characters on a set of respective spline curves. A designer or other user can customize the fonts and user experience by creating an episode package that specifies words to include in the user interface, and details about actions to take when certain events fire. The episode package can include media effects to play when a particular event associated with the media effect occurs.
