 <p>I designed an user study, made some early test run with a pre-study and then, with some small study adjustments and a heavily changed implementation, I performed the actual study.</p>
 <h3>Study Design</h3>
-<p>The general design of the user study is as follows:</p>
+<p>The pre-study and study design and purpose do not match the typical structures of pre-studies and (actual) studies to same degreee. Typically, you want to choose between a between-subject and a within-subject study structure, to generate data, that helps to evalute the different levels of the independent variables of the study. The three independing variables being the locomotion system, the interaction system and the cyber-sickness reduction technique.</p>
+<p>Due to the structure of the IVAR course, we basically only had to have one level of each independent variable, meaning only one implementation of each system / technique. We would then compare the results to the results of the implementation of the other course students. This comparision is rather vague, given our freedoms in the implementation, reaching from only changing the position of some coins to re-doing the entire race track from the group up in another game engine.</p>
+<p>I extended this task a bit to come closer to a typical study structure again, by performing a pre-study with a different implementation / level of all three systems / independent variables.</p>
+<p>The study is therefore a between-subject design, with two levels of each independent variable.</p>
