One of the things that frustrates me a lot and is not mentioned in the reading are the air blowers found in public bathrooms. As you might now some of the malls or other public bathrooms for some reason decide to put air blowers instead of paper towels for drying hands. In most cases these blowers can’t detect when we place our hands under and we are left there standing next to to the machine going forwards and backwards with our hands like we are doing some stupid dance choreography. Not to mention how some bathrooms have very strong blowers which will dry my hands faster, but I will go out with a wet shirt. Papers are towels are easier to use, straight forward and do the job much quicker and better than the blowing machines.
In order to avoid my design being hard or unpleasant to use I will apply the following principals to my design. I will make the buttons look clickable and the links underlined or colored differently so it is obvious to the user that button or link is intended for clicking. I will make sure that the user gets immediate response to their interaction of any part of the design and I will place buttons and other interactive objects in places where it makes sense. No hidden menus or buttons which are weirdly colored or hidden so they are barely visible. Some websites don’t do the color matching correctly so the links look like every other word in the sentence and is hard to determine on what to click, I will make sure I don’t do such thing.
