WEBVTT 00:00:03.044 --> 00:00:04.087 Even though you're a lot 00:00:04.087 --> 00:00:08.383 smarter and you have ten fine tuned fingers. 00:00:08.466 --> 00:00:11.720 Have you ever struggled to open a simple door? 00:00:11.803 --> 00:00:15.890 The chances are 100%. 00:00:15.974 --> 00:00:18.560 Unless you grew up and live here 00:00:18.560 --> 00:00:21.896 where there are no doors. 00:00:21.938 --> 00:00:23.064 Norman Doors. 00:00:23.064 --> 00:00:27.902 What is the difference between good and bad design? 00:00:27.986 --> 00:00:32.157 How can such a simple thing as a door be confusing? 00:00:32.240 --> 00:00:35.243 Those of us who live active lives in large cities 00:00:35.410 --> 00:00:38.872 experience poorly designed doors every single day. 00:00:39.039 --> 00:00:41.583 We have trouble opening doors. 00:00:41.583 --> 00:00:45.462 We push doors that were meant to be pulled. 00:00:45.545 --> 00:00:48.798 We pull doors that are meant to be pushed. 00:00:48.882 --> 00:00:54.471 We walk right into doors that we can never pull nor push, but that slide. 00:00:54.554 --> 00:00:57.766 These doors are named Norman Doors. 00:00:57.849 --> 00:01:00.518 They signal that you should do the opposite 00:01:00.518 --> 00:01:06.441 of what you're actually supposed to do, and they need a sign to correct it. 00:01:06.524 --> 00:01:09.652 Norman Doors are named after Don Norman, 00:01:09.903 --> 00:01:14.074 who coined the term user experience. 00:01:14.157 --> 00:01:18.745 Don Norman wrote the legendary book The Design of Everyday Things. 00:01:18.787 --> 00:01:21.790 He's a professor of psychology, 00:01:21.915 --> 00:01:27.128 cognitive science and computer science and worked as a vice president 00:01:27.128 --> 00:01:32.717 of Advanced Technology at Apple and as a design executive at HP. 00:01:32.801 --> 00:01:38.640 Yet he still struggles to walk through a simple door, just like the rest of us. 00:01:38.723 --> 00:01:42.852 Don Norman helps us understand, but it's not usually us 00:01:42.852 --> 00:01:46.231 who are the problem, but poorly designed doors 00:01:46.314 --> 00:01:51.402 or poorly designed apps or poorly designed microwaves 00:01:51.486 --> 00:01:55.657 or poorly designed nuclear power plants, which are the problem. 00:01:55.740 --> 00:02:01.454 The fundamental design problem is that discoverability and understanding fail. 00:02:01.538 --> 00:02:05.250 Discoverability is essential in all designs. 00:02:05.333 --> 00:02:10.088 You must design the relevant components so they are visible and communicate 00:02:10.088 --> 00:02:15.385 the right message to people who use your products and services. 00:02:15.426 --> 00:02:20.598 So how can you design for discoverability and understanding? 00:02:20.682 --> 00:02:26.813 The Golden rule is to always consider what actions are possible. 00:02:26.896 --> 00:02:27.814 Ask yourself, 00:02:27.814 --> 00:02:32.318 Is it possible to figure out where and how they should be performed? 00:02:32.402 --> 00:02:36.114 Make sure that it's easy to discover and understand what to do. 00:02:36.281 --> 00:02:39.534 How is the product's supposed to be used? 00:02:39.617 --> 00:02:44.831 What do the different controls and settings mean with those that people push? 00:02:44.873 --> 00:02:49.335 You must provide signals and signifiers that intuit heavily indicate to push 00:02:49.419 --> 00:02:50.670 and where to push. 00:02:50.670 --> 00:02:54.048 Put a vertical plate on the side 00:02:54.132 --> 00:02:55.925 with doors that people pull. 00:02:55.925 --> 00:03:00.138 You must put a door handle that naturally indicates to pull. 00:03:00.221 --> 00:03:02.807 These are natural signals. 00:03:02.807 --> 00:03:06.269 Humans can naturally interpret and understand them. 00:03:06.352 --> 00:03:08.771 Make it obvious what to do. 00:03:08.771 --> 00:03:13.026 Humans, and perhaps even cats naturally know what to do. 00:03:13.109 --> 00:03:14.944 No labels needed. 00:03:14.944 --> 00:03:18.865 With complex devices, discoverability and understanding 00:03:19.073 --> 00:03:23.995 can require guidance from manuals, instructions, or even courses. 00:03:24.037 --> 00:03:26.247 That's okay, 00:03:26.331 --> 00:03:29.042 but only if it's necessary. 00:03:29.042 --> 00:03:32.879 But with simple things, this is not good enough. 00:03:32.962 --> 00:03:36.132 It's a mistake made by lazy or ignorant design teams. 00:03:36.132 --> 00:03:39.344 And we trust that's not you and your team. 00:03:39.427 --> 00:03:42.680 So let's rid the world of frustrating doors, 00:03:42.764 --> 00:03:47.060 frustrating interfaces, and overcomplicated designs. 00:03:47.143 --> 00:03:50.521 Let's rid the world of unnecessary manuals. 00:03:50.605 --> 00:03:54.025 Let's create products that are easy to understand 00:03:54.108 --> 00:03:56.736 and make our lives smoother and easier. 00:03:56.736 --> 00:03:58.446 Whenever possible. 00:03:58.446 --> 00:04:00.865 It's not about magic. 00:04:00.865 --> 00:04:06.496 It's about us designers and learning and implementing essential design skills. 00:04:06.579 --> 00:04:10.416 You can use these insights when you design 00:04:10.500 --> 00:04:13.795 apps, websites, services, 00:04:13.836 --> 00:04:17.507 household machines, or whatever your design. 00:04:17.590 --> 00:04:19.092 Sign up for our courses. 00:04:19.092 --> 00:04:22.011 Learn from top design specialists. 00:04:22.011 --> 00:04:23.263 Get your certificate. 00:04:23.263 --> 00:04:25.556 It's industry recognized. 00:04:25.556 --> 00:04:27.350 Interaction Design Foundation.
