Dialogue: 0,0:00:01.25,0:00:04.50,Default,,0000,0000,0000,,Hi, I am Scott Klemmer, I’m an associate professor of computer science,
Dialogue: 0,0:00:04.50,0:00:08.72,Default,,0000,0000,0000,,and I’d like to welcome you this online class, introducing human-computer interaction.
Dialogue: 0,0:00:08.72,0:00:13.01,Default,,0000,0000,0000,,This online class is based on the class I’ve been teaching in Stanford for several years now,
Dialogue: 0,0:00:13.01,0:00:16.36,Default,,0000,0000,0000,,and it synthesizes materials from a number of sources.
Dialogue: 0,0:00:17.49,0:00:20.80,Default,,0000,0000,0000,,First and foremost is the human, the person that’s using the system
Dialogue: 0,0:00:20.80,0:00:23.08,Default,,0000,0000,0000,,and the other people that they work and communicate with.
Dialogue: 0,0:00:23.57,0:00:27.12,Default,,0000,0000,0000,,Then you got the computer, that’s the machine and the networked-up machines that run the system.
Dialogue: 0,0:00:27.12,0:00:30.67,Default,,0000,0000,0000,,And then you got the interface that represents the system to the user.
Dialogue: 0,0:00:30.67,0:00:35.65,Default,,0000,0000,0000,,HCI is the design, implementation and evaluation of user interfaces.
Dialogue: 0,0:00:35.65,0:00:39.48,Default,,0000,0000,0000,,This course is going to teach you a set of tools for doing this effectively.
Dialogue: 0,0:00:39.48,0:00:43.92,Default,,0000,0000,0000,,At the onset of the design project, we often don’t know what the problem is
Dialogue: 0,0:00:43.92,0:00:47.75,Default,,0000,0000,0000,,or what the space of possibilities might be, let alone what the solution should be.
Dialogue: 0,0:00:47.75,0:00:50.79,Default,,0000,0000,0000,,Consequently, real-world design is often iterative,
Dialogue: 0,0:00:50.79,0:00:53.47,Default,,0000,0000,0000,,failed fast so you can succeed sooner.
Dialogue: 0,0:00:53.47,0:00:56.97,Default,,0000,0000,0000,,Often it benefits from trying and comparing options.
Dialogue: 0,0:00:56.97,0:01:01.18,Default,,0000,0000,0000,,Finally, it’s important to focus on the people who are going to use your system.
Dialogue: 0,0:01:01.18,0:01:05.45,Default,,0000,0000,0000,,Good design brings people joy: it helps people do things that we care about,
Dialogue: 0,0:01:05.45,0:01:08.05,Default,,0000,0000,0000,,and helps us connect people that we care about.
Dialogue: 0,0:01:08.05,0:01:13.04,Default,,0000,0000,0000,,Good user interfaces can have a tremendous impact on both [the] individual’s ability to accomplish things,
Dialogue: 0,0:01:13.04,0:01:15.82,Default,,0000,0000,0000,,and societies’. Graphical user interfaces help
Dialogue: 0,0:01:15.82,0:01:18.41,Default,,0000,0000,0000,,with computing a hundreds of millions of tasks,
Dialogue: 0,0:01:18.41,0:01:22.98,Default,,0000,0000,0000,,enabling us to do things like create documents, and share photo and connect with family
Dialogue: 0,0:01:22.98,0:01:24.97,Default,,0000,0000,0000,,and find information.
Dialogue: 0,0:01:24.97,0:01:30.10,Default,,0000,0000,0000,,Bad design is frustrating and costs lives: medical devices, airplane accidents
Dialogue: 0,0:01:30.10,0:01:35.46,Default,,0000,0000,0000,,and nuclear disasters are just three domains where bad user interfaces and software errors
Dialogue: 0,0:01:35.46,0:01:38.40,Default,,0000,0000,0000,,have caused serious injury and many deaths.
Dialogue: 0,0:01:38.40,0:01:41.78,Default,,0000,0000,0000,,These are big ticket items that take a lot of time to produce.
Dialogue: 0,0:01:42.01,0:01:44.96,Default,,0000,0000,0000,,What really gets me is that many of these interface problems
Dialogue: 0,0:01:44.96,0:01:47.11,Default,,0000,0000,0000,,could have easily been avoided.
Dialogue: 0,0:01:47.11,0:01:53.50,Default,,0000,0000,0000,,Fixing these problems requires following just basic principles like consistency and feedback.
Dialogue: 0,0:01:53.69,0:01:56.63,Default,,0000,0000,0000,,If effective principles for interface design were widely known
Dialogue: 0,0:01:56.63,0:01:59.79,Default,,0000,0000,0000,,some of these disasters might have been avoided.
Dialogue: 0,0:02:00.33,0:02:03.66,Default,,0000,0000,0000,,This is one of the major reasons that I created this course.
Dialogue: 0,0:02:03.66,0:02:08.15,Default,,0000,0000,0000,,Bad design causes problems and degrades people[’s] quality of life in many smaller ways too.
Dialogue: 0,0:02:08.32,0:02:11.10,Default,,0000,0000,0000,,Think of all the time that you waste on your bank's website
Dialogue: 0,0:02:11.10,0:02:16.13,Default,,0000,0000,0000,,or trying to figure out why the wifi doesn't work, or trying to set something on your digital camera.
Dialogue: 0,0:02:17.08,0:02:19.65,Default,,0000,0000,0000,,Let's say these frustrations take
Dialogue: 0,0:02:19.65,0:02:22.34,Default,,0000,0000,0000,,10 minutes a day for the average American.
Dialogue: 0,0:02:22.34,0:02:28.24,Default,,0000,0000,0000,,With 300 million people in America alone, that’s 3 billion person-minutes a day.
Dialogue: 0,0:02:28.24,0:02:31.12,Default,,0000,0000,0000,,or 18 billion person-hours a year.
Dialogue: 0,0:02:31.66,0:02:34.96,Default,,0000,0000,0000,,That's a lot of time that we could’ve spent making the world a better place.
Dialogue: 0,0:02:35.23,0:02:38.85,Default,,0000,0000,0000,,Oftentimes, the best interfaces become invisible to us.
Dialogue: 0,0:02:38.85,0:02:43.86,Default,,0000,0000,0000,,When an interface becomes automatic by practice, by design and most often by a combination,
Dialogue: 0,0:02:43.86,0:02:47.95,Default,,0000,0000,0000,,our attention shifts from manipulating an interface to accomplishing a task.
Dialogue: 0,0:02:47.95,0:02:51.21,Default,,0000,0000,0000,,It’s kind of like a blind person who has practiced working with a cane.
Dialogue: 0,0:02:51.21,0:02:55.31,Default,,0000,0000,0000,,After all those hours of practice, they no longer feel the cane.
Dialogue: 0,0:02:55.31,0:02:59.64,Default,,0000,0000,0000,,Their sensory perception is at the end of the cane, experiencing the world.
Dialogue: 0,0:02:59.64,0:03:03.82,Default,,0000,0000,0000,,That attentional shift is what happens when an interface becomes intuitive.
Dialogue: 0,0:03:03.82,0:03:08.36,Default,,0000,0000,0000,,Designing great user interfaces requires enormous creativity and a lot of hard work.
Dialogue: 0,0:03:08.36,0:03:11.71,Default,,0000,0000,0000,,But designing pretty good user interface is pretty easy
Dialogue: 0,0:03:11.71,0:03:15.34,Default,,0000,0000,0000,,if you know some methods, techniques and principles. I’ll show how.
Dialogue: 0,0:03:16.25,0:03:18.34,Default,,0000,0000,0000,,Summarize this introduction:
Dialogue: 0,0:03:18.34,0:03:22.96,Default,,0000,0000,0000,,In this course you're going to learn a process where people’s tasks, goals and values drive development.
Dialogue: 0,0:03:22.96,0:03:26.33,Default,,0000,0000,0000,,You’re going to learn to work with users throughout the process;
Dialogue: 0,0:03:26.33,0:03:31.25,Default,,0000,0000,0000,,to assess decisions from the vantage point of users, their work and their environment;
Dialogue: 0,0:03:31.25,0:03:36.59,Default,,0000,0000,0000,,to pay attention to people's abilities and situation; and to talk to the actual experts.
Dialogue: 0,0:03:36.59,0:03:42.52,Default,,0000,0000,0000,,You'll learn to talk with a variety of users — both regular and extreme users — and a wide variety of stakeholders.
Dialogue: 0,0:03:42.52,0:03:45.59,Default,,0000,0000,0000,,As my colleague John Zimmerman reminded me recently,
Dialogue: 0,0:03:45.59,0:03:49.68,Default,,0000,0000,0000,,users are just one of the many stakeholders in the design process.
Dialogue: 0,0:03:49.68,0:03:56.12,Default,,0000,0000,0000,,Other stakeholders matter too, helping ease development and costs of production, support maintenance,…
Dialogue: 0,0:03:56.12,0:04:00.28,Default,,0000,0000,0000,,In designing for people, don't forget the other pieces of the puzzle.
Dialogue: 0,0:04:01.73,0:04:05.62,Default,,0000,0000,0000,,In creating this class, I’ve integrated materials from a lot of sources,
Dialogue: 0,0:04:05.62,0:04:09.06,Default,,0000,0000,0000,,including classes like James Landay’s, books like Don Noman’s
Dialogue: 0,0:04:09.06,0:04:12.00,Default,,0000,0000,0000,,and papers like from the CHI Conferences.
Dialogue: 0,0:04:12.19,0:04:14.14,Default,,0000,0000,0000,,For those who'd like to learn more,
Dialogue: 0,0:04:14.14,0:04:17.56,Default,,0000,0000,0000,,I’ve put a Further Reading slide at the end of many of my lectures.
