For the course human factors my group and I redesigned the user interface of a CD-Player.
Here you can see a picture of the old version.
Our redesigned version had several changes. These were making the buttons more comfortable, changing the kind of cd drive and getting rid of several buttons that were confusing.
Here is the new version. The first picture is where the system is turned off and the second one is on.
We came to the conclusion through our usability test that our new designed interface is better than the old one, however users thought we have integrated a touch screen, which created confusion but we didnt do so due to several reasons but we think this problem only occurred as we have tested it on a computer.
