Here are some issues we discovered during the test. Not all of them are mentioned, just the major ones (for the sererity ratings we used Jakob Nielsen’s serverity ratings for usability problems):
– Game does not restart properly after saving the high-score (severity: 5)
possible solution: some variables might not be reinitialized properly
– electro-track is to hard to play. Even for users with a common knowledge of music (serverity: 3)
possible solution: make an other song that is slower and easier to play
– Specialsound-button is a bit hard to reach (serverity: 2)
possible solution: rearrange buttons according to fitt’s Law

Today we are testing our application with the Think Aloud method. We prepared some tasks the user had to perform during the trials. The user also had to verbalize his thoughts while interacting with MoveTheBeat.
Here are the tasks/Questions the user had to fullfil:
Spiele das Spiel MoveTheBeat zwei mal. Wähle den Electro-track für das erste und den HipHop-track für das zweite Spiel. Mache jeweils am ende des Spiels ein Bild für den High-Score von dir. Versuche während des Versuchs zu beschreiben was du gerade tust und was du vorhast. Auch Probleme mit der Applikation können laut ausgesprochen werden. Erwarte nicht von uns dir dabei zu helfen. Es geht darum selbst heraus zu finden wie die Anwendung funktioniert.
Time – 15:00
Place – Alex‘ kitchen
recording technique – Iphone, paper and pencil, brain
Here are some pictures of our test setup:
As you may can guess, we fixed the problems we found in our heuristic evaluation. The first one was important but simple. We just had to implement a high score display into the actual game. For second problem we found we used the same „load function“ as in the other menues of our application. The user has to put his hands over the „photobutton“ as it changes the color. After about three seconds a photo will be made. This prevents the user from accidantally taking a photo.
Even though we just found two problems with our heuristic evaluation we are still glad that we have done it because, as you can also see in the ratings, the problems we found were very serrios.
