-One of the basic principles of the Fenfire user interfaces is continuity.
+One of the basic principles of the Fenfire user interface is continuity.
 Continuity helps the user to perceive the interface as cognitively
-coherent --- things are related to each other, not disconnected. This
+coherent - things are related to each other, not disconnected. This
 reduces load in the user's working memory.

+ 
 Some of the ideas aiming to maintain continuity in the Fenfire user
 interface (such as focus-context) have been proved to be efficient by
 earlier researchers. Several ideas presented here are, however, genuinely
 new and thus need to be subjected to rigor experimenting and testing. We
 plan to test the usability of the ideas first in basic cognitive tasks
 before implementing and testing them in a larger context.

 The first-phase experiments include tasks varying from very simple
 perceptual tasks (such as visual search and recognition) to more complex
 problem-solving tasks. The experiments will be conducted with about ten
-naïve participants per experiment. The data will include response times
+naïve participants per experiment. The data will include response times
 and error rates of the participants. In addition, surveys or short
 interviews can be used to collect the personal opinions of the
 participants about the tested idea.
 
-In the next phase, the techniques will be tested in a more realistic 
-situation.
+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
+user to trace visual connections between information items.
+
+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.
+
 Finally, we will carry usability tests on a simulated interface, in which
 several ideas are implemented simultaneously. The users will be observed
 in realistic use situations. Behavioral data will be gathered in verbal
 protocols, videotaping, and surveys.
