What's Interaction Design?3:06 with Hope Armstrong
To get started, let's consider the definition of Interaction Design and how it relates to the User Experience.
- Interaction Design: “Interaction Design is the creation of a dialogue between a person and a product, system, or service. This dialogue is both physical and emotional in nature and is manifested in the interplay between form, function, and technology as experienced over time.” - John Kolko
- The Media Equation: The theory that people tend to treat computers as if they were either real people or real places
- The Media Equation: How People Treat Computers, Television, and New Media Like Real People and Places by Byron Reeves and Clifford Nass
- Designing Interfaces by Jenifer Tidwell, Charles Brewer, and Aynne Valencia-Brooks
[MUSIC] 0:00 Hi, my name is Hope and I'm a product designer at Treehouse. 0:09 In this course, 0:14 I'll teach you about interaction design, which is commonly abbreviated as IXD. 0:15 We'll take a look at the theories and 0:21 then apply them practically in a design program. 0:23 First up, what is interaction design? 0:27 Well, it's a subset of user experience. 0:30 While user experience is a comprehensive look at the entire user journey, 0:32 interaction design focuses on the interactive experience. 0:39 Let's take a look at how Jon Kolko, 0:43 the author of Thoughts on Interaction Design defines it. 0:45 Interaction design is the creation of a dialogue between a person and 0:50 a product, system or service. 0:54 The dialogue is both physical and emotional in nature. 0:57 And as manifested in the interplay between form, function, and 1:02 technology, as experienced over time. 1:06 You can think of it as the relationship between a person and a product. 1:10 As people interact with the product, there's a back and forth conversation. 1:15 In the book designing interfaces, the author's 1:21 described the exchange of information between the person and the software. 1:24 The person expects continuous feedback that their actions are being acted upon, 1:29 and their needs are being met. 1:34 This feedback loop forms a substantial part of the user experience. 1:37 Generally, we wanna make that conversation as smooth as possible. 1:42 In the 90s, researchers at Stanford University discovered that people 1:48 tend to treat computers as if they were either real people or real places. 1:52 This is called the media equation. 1:57 Following that logic, humans expect digital products to be human like. 2:02 As designers we want to create a natural human like conversation, 2:07 anticipate needs, and exceed expectations. 2:12 Think of a time you were mad at your computer for shutting down unexpectedly. 2:16 Or at time a printer continuously claimed there was a paper jam that you just 2:21 couldn't find. 2:25 And then spontaneously started printing 2:27 after you simply jiggle the paper tray a bit. 2:30 You probably got annoyed, how rude of their printer to behave like that? 2:32 When products fail us we have an emotional response. 2:36 It's as if the inanimate object has broken our trust, and 2:40 our relationship with it is fractured. 2:44 It's moments like these were the fundamentals of interaction design, 2:48 enable us to empathize with the user, and 2:52 preemptively designed solutions that prevent frustration and broken trust. 2:55 In the next video, 3:00 I'll introduce the five dimensions that form the foundation of interaction design. 3:01
