Hey folks, welcome to the series of videos on psychology and human factors. The goal of this video, in particular, is to introduce you to the high level ideas that we'll be talking about in this series of videos and then in each video, you'll be learning about one specific area of those ideas. Now in general, this series of videos is about understanding your users but in particular, it's about understanding users in general. General information about how people interact with technology. In this course, you'll be spending most of your time figuring out specific characteristics about your users, understanding their specific nature and how they will interact with a technology that you're building specifically for them. But it is also important to understand principles that are broadly true across all groups of users. In this series of videos, you're going to be learning about the general stuff and in the coming weeks, you'll be learning about how to figure out the specific stuff for your specific application. A simpler way to think about this series of videos is that it's effectively helping you avoid reinventing the wheel. We'll be teaching you, in this series of videos, all sorts of things about how humans are and what that means in terms with how they interact with technology. And without knowledge about these general principles, you will have to rediscover them, reinvent that wheel every single time that you design a new application. This stuff is pretty important, it gives you a foundation for doing the more specific stuff much more effectively. The main learning objective for this series of videos is learning about how people interact with technology in general. But through this process, we're going to have three additional secondary learning objectives, as well. One, you'll become familiar with key concepts, ideas and theories that will come up again and again throughout this course and actually, throughout the entire specialization, as well. For instance, you're going to be learning about theories, about how people point at things and with pointing, being a such a critical part of how we do almost everything in a user interface. For instance, to move a slide, back and forth, I have to first point at the key. We need to know people how people's desires to hit a target are manifest through their physical actions. You'll be learning about how humans make mistakes and the types of mistakes they make. Obviously, very generally important for all sorts of different technologies. You'll be learning about how humans need feedback from interfaces, again, very generally important. And you will be learning about, for instance, cognitive theories of how people interact with the technologies around them. One my favorites, Professor Yarosh will be covering this, is the theory of actually distributed cognition, where we put some of our cognition into the tools that we use on a day-to-day basis. The second secondary learning objective for this series of videos is that we really want you to see in this series of videos is how designing an interface could seem like a massively complex task. My goodness, where do I get started? In this series of videos, you'll begin to see how pretty straightforward principles and ideas and theories can take you a large way towards your goal. So that this complex task can begin to break down into these more easily understandable ideas, theories, principles, and so on. Lastly, by the end of the series of videos, you will really buy into this idea that user interface design is an incredibly interdisciplinary field. You'll be learning about ideas and concepts and principles that come from psychology, that comes from cognitive science, kinesiology, architecture, and even avionics. This is actually one thing I really like about the user interface, a design field, that it's very interdisciplinary, this series of videos will really sell that point quite a bit. I look forward to seeing you in this series of videos.
