Human Computer Interaction (HCI) - Interaction Design Foundation

Learn the entire spectrum of UX design from 32 beginner to advanced courses on Interaction Design Foundation. Get taught by industry experts and gain recognized certificates to advance your career.

Interactions between computers and humans should be as intuitive as conversations between two humans—and yet many products and services fail to achieve this. So, what do you need to know so as to create an intuitive user experience? Human psychology? Emotional design? Specialized design processes? The answer is, of course, all of the above, and this course will cover them all.

Human-computer interaction (HCI) is about understanding what it means to be a user of a computer (which is more complicated than it sounds), and therefore how to create related products and services that work seamlessly. It’s an important skill to master, because it gives any company the perspective and knowledge needed to build products that work more efficiently and therefore sell better. In fact, the Bureau of Labor Statistics predicts the Computer and IT occupation to grow by 12% from 2014–2024, faster than the average for all occupations. This goes to show the immense demand in the market for professionals equipped with the right computer and IT skills.
