Oh. Is it on ?
We're here.
Okay.
Okay , um. In order to see what the functional requirements were to be found , um a hundred people were tested in a usability laboratory through just their habits to n know their habits were observed and questionnaires were given out. Um , the findings in in some cases matched what we were talking about. Custome Customers and users don't like the way remote controls look , they don't like the way they feel , they don't think they match their operating behaviour , and an example is what we were talking about , the buttons , they only use ten per cent of the buttons , so later on there's a study of the buttons that they use most and I think we should design according to these buttons. Easy to lose , and R_S_I_. I don't know what R_S_I_ means. Um the person that did the questionnaire obviously did , I don't have a clue.
