Usability in the Real World2:35 with Dan Gorgone
No matter where you are, good design improves experiences. So, if you're still curious about how to define usability, let's step out of the web for a moment and look at some real life examples.
If you're still curious about how to define usability, 0:00 let's step out of the Web for a moment and look at some real life examples. 0:03 We should be able to spot some similarities to online design 0:07 because no matter where you are, good design improves experiences. 0:10 Let's take a look at the climate control on the dashboard of a car— 0:16 this model features a knob that you can turn to set the temperature inside the car. 0:20 Using colors, users can see that if you turn the knob one way 0:26 the temperature will get cooler; the other way will raise the temperature. 0:29 Newer car models reduce the guess work 0:34 and allow users to set an exact temperature. 0:36 However, present too many knobs or controls 0:39 and the functionality of the interface becomes confusing— 0:42 you're not sure what to push or turn or move. 0:46 Therefore, a balance must be struck, and you can bet 0:48 car companies do many rounds of testing to ensure the interface 0:52 is intuitive and effective. 0:56 Here's another example—buildings are required by law 0:59 to have exit signs placed throughout each floor. 1:03 Safety is one of the central goals behind this design; 1:07 therefore, it's important for people to understand the meaning 1:10 of the sign when they see it. 1:13 When an exit door is near, the exit sign is placed above it. 1:16 Because of the proximity, people can be expected to associate 1:20 the meaning of the sign—an emergency exit—with the door below it. 1:23 If a door is not close by, exit signs also have built-in arrows 1:29 that can be used to provide a visual cue. 1:33 And lastly, these signs need to work at all times, 1:36 so they're visible during the day and they light up at night 1:40 to be seen during darker hours. 1:44 The exit sign can be considered a real life call-to-action of sorts; 1:47 if you need to find an exit for the building you're in, 1:51 the sign tells you where to go. 1:53 The same could be said for many important buttons on websites. 1:55 If you want to find out more information on a certain topic, 1:59 the corresponding menu item is what you would click. 2:02 On a mobile app, the clearly labeled button is what you would touch. 2:06 So, look around where you are right now 2:10 and you'll notice some elements of design 2:12 that went into the room you're sitting in, 2:15 or the car you drive, or even your phone. 2:17 Good design should make things easier to do. 2:20 But the best design is so intuitive, it's often not even noticed by the people that use them. 2:24 Consider this as you work on your own website and app in the future. 2:30
