Sammanfattning: This is a study about software usability and information presen-tation in an Android application. The application is meant topresent the information coming being sent on the CAN buss ofa car or to listen to the messages being sent by just a few ECUconnected via a CAN buss. The study aims to evaluate the usabi-lity of the application based on an exploratory research method.The study was conducted using an iterative processes, where wefirst created a prototype. The prototype was then presented to anumber of users and they were asked to do a number of simpletasks within the application. We then used the feedback from thisexamination to improve the usability of the application. After thiswe did a second presentation of the application and compared itto the results to the results from the previous tests to see if wesucceeded in increasing the usability of the application.The first study tests showed that there were several weaknesses inthe application that we ourselves did not see. It showed that ourbackground was too prominent and that the text became hard toread, along with several other small things that we corrected. Wethen saw in our second tests that most parts of the applicationhad improved. There were still some parts of the application thatcould still use some development, and all people what differentthings in an application.
