==Evaluation==
 
Interfaces where a usability life cycle is applied are subject to evaluation. Evaluation, done by the User Interface Engineering team can be carried out with different Methods:
 
#Usability Interviews and tests with 'Thinking Aloud'
#GUI Workshops 'e.g. Card Sorting'
#Software based evaluation
 
=== Usability Interviews (Thinking Aloud/Think Aloud Protocol<ref>http://en.wikipedia.org/wiki/Think_aloud_protocol Wikipedia on 'Think Aloud Protocol'</ref>) ===
 
From our point of view the method of choice because it balances result and effort.

Usability interviews are conducted to discover, document and classify usability issues for
 
* a specific release (e.g. PubMan 2.0.0.1)
* a functional prototype
* a prototype draft
 
Up to 8 interviews are usually sufficient to discover the main flaws of a GUI. The interviewer just provides tasks for his participant. The participant does all tasks on his own and should be encouraged to comment on his actions. It is not recommended for the interviewer to interfere in any form. If the participant gets stuck and there are important steps to follow, he gets a hint how to continue.
 
Interviews can be recorded optionally if participants agree. If a participant is not able to solve a task or step it will be noted as a fatal usability issue. For later interviews with a more standardized set of tasks the issues are to be classified in the following way:
 
#Fatal (Task could not be finished successfully or in a proper way)
#Serious (Task could not be finished on the first attempt or user performance is bad)
#Minor = (The user hesitates, is not sure or does not feel comfortable with the flow)
 
For each interview the UIE team provides an interview outcome. The document contains all tasks, observation notes and comments of participants. Additionally the interviews collect demographic characteristics as well to prepare data needed for personas. After a valid number of interviews exists they are analysed and summarized.

For each workshop the UIE team prepares a topic. The following topics are already covered:
 
===Workshops 2008===
*'''Scheduled: 09.12.2008 - 10.12.2008, Bibliotheca Hertziana - Max Planck Institute for Art History'''
<b>Topics</b>: A brainstorming can be found on [[Faces_GUI#User_Interface_Evaluation|Faces GUI]].

==Software based Evaluation==
 
Currently the pubman prototype is monitored by an open source application called [http://www.labsmedia.com/clickheat/index.html ClickHeat]. This solution generates pictures called heat maps. Heat maps show where users click (dots) and how often (colour).
 
Example:
 
[[Image:clickheat_depositor.png|framed|center|Heat Map of Depositor Workspace]]
 
Software based evaluation is not conducted for R3. Currently no open source application is available for analysing dynamic pages.
