Usability testing
+'''''''''''''''''
+
+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
+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
+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.
+
+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.
