+\subsection{Technical details}
 The UI has been implemented using HTML5, vanilla CSS and vanilla JS, with the
 exception of the \textit{FoamTree} library from the Carrot2 project to handle
 displaying the clustering bar to the left of search results.
 
-Event handlers offered by \textit{FoamTree} allowed for the implementation of

 \section{User evaluation}
+The user evaluation was conducted remotely using Microsoft Teams by selecting
+three of my colleagues and making them install and run my project on their local
+system. The examination approximately took 20 minutes for each test subject,
+including installation.
+
+The questionnaire was implemented using Qualtrics at \href{TBD}{this link}.
+
+Data for the evaluation was collected using a questionnaire with a ``before
+test'' and an ``after test'' section.
+
+In the ``before test'' section, users expressed their agreement to test
+procedures and stated their level of familiarity with image search text
+retrieval systems, stating in particular if they ever searched for user created
+images or stock photos. All participants stated they were mostly familiar with
+TR image search systems, and they had the chance to search for user created
+images. Only one participant never searched for stock photos.

+Numeric values represent a 5-tier likert scale for the ``Familiarity with image
+TR systems question (from 1 to 5, ``Not familiar at all'', ``Slightly
+familiar'', ``Moderately familiar'', ``Very familiar'', ``Extremely familiar'')
+and a 7-tier likert scale on all other questions (from 1 to 7, ``Strongly
+Disagree'', ``Disagree'', ``Slightly disagree'', ``Neither agree or disagree'',
+``Somewhat agree'', ``Agree'', ``Strongly agree''). The start and end times are
+expressed in CEST without DST (corresponding to the local time of participants).
+All participants started the questionnaire before they started effectively using
+the IR system, so this data can also be used to measure the experiment's length.
