One of the basic principles of the Fenfire user interfaces is continuity. |

Continuity helps the user to perceive the interface as cognitively |

For example, fillets are designed to enhance perceivability of visual |
|
|
connections between interface elements. Fillets have been tested in a |
|
|
controlled experiment, showing that fillets do facilitate recognizing |
|
|
certain visual structures in a collection of visual items and their |
|
|
interconnections, compared to more common implementations. In the next |
|
|
phase, fillets will be tested in a more realistic situation requiring the |

Textured backgrounds implement continuity by providing unique, permanent |
|
|
visual context for interface elements to facilitate search and recognition |
|
|
of the elements in prolonged use. Textures will be tested to show that the |
|
|
user can implicitly memorize textures during interaction with the |
|
|
interface elements and use this information to recognize the elements |
|
|
faster and more accurately. We will also conduct readibility tests on |
|
|
textures to show that a textured background of text does not necessarily |
|
|
impair either the legibility or the readability of the text. |
