Feedback is the best way to let a person know that they did something correctly or incorrectly. If they don't have feedback they are left sitting there waiting and wondering. Have you ever tried to open an application on your computer and nothing happens. You wait for a few seconds then try it again. Still, if nothing happens you start to wonder if you computer froze or if you did something wrong.
"The absence of sound can mean an absence of information, and if feedback from an action is expected to come from sound, silence can lead to problems."
-Donald Norman (Norman, 2002)
This week we have been testing our calculator designs. It has given me a lot of really good feedback. Since it is not a working model if the user does something and it is not how I designed it to work I have to just sit there and they are left wondering why it didn't work. It has been a good chance to see how the feedback of my design is crucial to having a well designed piece and also I get verbal feedback from the person testing my design.
