Human-Centered Design: an Introduction

Por: Coursera . en: , ,

  • Introduction
    • A brief introduction to the topics and goals of this Interaction Design Specialization
  • Needfinding
    • This module’s videos and assignment cover a really important topic: where can you get good design ideas from? Ideas that help you create meaningful designs that have a real impact on real people’s lives. Of course, good ideas come from lots of places. And wherever they come from, great. There are a few strategies I’ve found that are especially valuable, and that’s what we cover in this module’s videos. Given our focus on *real* people, we focus on going out, watching what people do, and talking to them. Check out the first video, describing participant observation. Combining observation with interviewing (the second video) provides a powerful foundation for needfinding and brainstorming.So what happens after you’ve observed a lot of stuff -- how do you connect the high-level needs to concrete design ideas? To help you bridge this gap, this module closes with a video on Creating Design Goals.
  • Rapid Prototyping: Wizard of Oz Prototyping
    • This module's lectures introduce storyboarding and several strategies and media for rapid prototyping, including paper, Wizard of Oz Prototyping, and video. An important part of the creativity of a designer is to think about how you can rapidly prototype and get feedback on your ideas. Because it's almost never the case that the first idea you have will be the best. As a designer, you can learn the most when you're creating and getting feedback on multiple alternatives. Your work will nearly always benefit from thinking broadly to find the right design, and then from lots of polish to get the design right. Prototyping is also a great way to achieve common ground across the design team and other stakeholders. We begin with storyboards, paper prototyping and mockups. Students often ask about the relationship between needfinding and prototyping: how closely does one flow into the other? Ultimately the quality of your final design is the real measure and there are lots of ways to get there. While most design work benefits from prototypes directly informed by the needfinding process, it's not required. This module seeks to introduce you to doing human-centered design, and walk you through one path that such an approach could take. In both this Specialization and in real life, you are welcome to revise your ideas as much as you like.
  • Heuristic Evaluation
    • With this module's videos, we turn our focus from brainstorming and prototyping to the concrete elements of interaction design. We introduce ten key principles of good design -- like the importance of feedback and helping people recover from errors. We call these heuristics -- watch the first video here. I hope you'll find these heuristics practical and applicable to your work both inside and outside class. The lectures discuss these heuristics with a bunch of examples drawn from real-world designs. The goal is to illustrate the many ways that designs can be successful or run into trouble. While heuristic evaluations (HEs) focus on issues that lead to improvement they can also identify areas we think show successful compliance with a heuristic
