 ====== Problems ======
+While finalizing the main study and planning the pre main study we detected that there a still a bunch of problems and we had a real chaos day. The problems within in the game could be solved but the minor issue was our end-to-end latency. In a previous blog entry we described how to measure this latency and in the same way we did it for the main study. But the calculated value was way too high and we don´t know where all the latency comes from.
+So we had discussions with our stake holder Andreas Schmid if a C++ application would be better than Qt and if we should conduct the main study with such high latency values.
+Despite this, we conducted the pre main study.
 ====== Pre main study ======
-====== References ======
+In the study before the study we tested the following aspects:
+  * perfect functionality of the game
+  * values of latency variance
+  * target sizes
+  * number of targets
+  * target speed
+  * time per participant
+This study was conducted in the TechLab with 6 participants ages 24,24,26,26,28,30.
+We resigned using the questionnaire for the gaming experience and the open interview after the test, since the functionality of the application was the most important subject.
+===== Results =====
+  * it takes about 10 minutes per participant
+  * we need to collect the email addresses separateley (privacy) and only of participants with realistic changes getting into the top 3
