Something that drives me crazy is the automatic entrance doors in C2, because sometimes when I walk towards one of the doors, it does not detect that I am there and stays closed. I usually end up moving towards the other door, only for the original door I wanted to use to suddenly open. I think this relates to Normans ideas of signifiers. There is no clear signifier showing exactly where I should stand for the sensor to detect me, and there is also nothing telling me whether I have been detected. This could be improved by adding a subtle marking showing where the sensor detects people, as well as a small light that turns on once someone has been detected. This would make the interaction much clearer instead of making the user guess what they are supposed to do.
Normans principles can be applied to interactive media by designing with the users perspective and human centred design (HCD) in mind rather than assuming that they will automatically understand how something works. Interactive media should have clear signifiers that communicate what can be interacted with, as well as feedback that clearly shows the user that their action had an effect. I also think mapping is important, because the way someone interacts with something should connect to the result they expect. Overall, Norman’s ideas made me think more about how an interactive experience should communicate with the user through its design, rather than needing instructions to explain how everything works.
