Hi, my name is Hope and
I'm a product designer at Treehouse.

3
00:00:14,310 --> 00:00:15,130
In this course,

4
00:00:15,130 --> 00:00:20,240
I'll teach you about interaction design,
which is commonly abbreviated as IXD.

5
00:00:21,570 --> 00:00:23,270
We'll take a look at the theories and

6
00:00:23,270 --> 00:00:25,740
then apply them practically
in a design program.

7
00:00:27,150 --> 00:00:30,270
First up, what is interaction design?

8
00:00:30,270 --> 00:00:32,785
Well, it's a subset of user experience.

9
00:00:32,785 --> 00:00:39,110
While user experience is a comprehensive
look at the entire user journey,

10
00:00:39,110 --> 00:00:42,270
interaction design focuses on
the interactive experience.

11
00:00:43,770 --> 00:00:45,770
Let's take a look at how Jon Kolko,

12
00:00:45,770 --> 00:00:49,010
the author of Thoughts on
Interaction Design defines it.

13
00:00:50,280 --> 00:00:54,890
Interaction design is the creation
of a dialogue between a person and

14
00:00:54,890 --> 00:00:56,730
a product, system or service.

15
00:00:57,960 --> 00:01:02,320
The dialogue is both physical and
emotional in nature.

16
00:01:02,320 --> 00:01:06,500
And as manifested in the interplay
between form, function, and

17
00:01:06,500 --> 00:01:09,210
technology, as experienced over time.

18
00:01:10,790 --> 00:01:14,390
You can think of it as the relationship
between a person and a product.

19
00:01:15,790 --> 00:01:19,840
As people interact with the product,
there's a back and forth conversation.

20
00:01:21,340 --> 00:01:24,300
In the book Designing Interfaces,
the authors

21
00:01:24,300 --> 00:01:29,520
described the exchange of information
between the person and the software.

22
00:01:29,520 --> 00:01:34,070
The person expects continuous feedback
that their actions are being acted upon,

23
00:01:34,070 --> 00:01:35,760
and their needs are being met.

24
00:01:37,090 --> 00:01:40,850
This feedback loop forms a substantial
part of the user experience.

25
00:01:42,670 --> 00:01:48,179
Generally, we wanna make that
conversation as smooth as possible.

26
00:01:48,179 --> 00:01:52,745
In the 90s, researchers at
Stanford University discovered that people

27
00:01:52,745 --> 00:01:57,246
tend to treat computers as if they were
either real people or real places.

28
00:01:57,246 --> 00:02:02,063
This is called the media equation.

29
00:02:02,063 --> 00:02:06,630
Following that logic, humans expect
digital products to be human like.

30
00:02:07,930 --> 00:02:12,770
As designers we want to create
a natural human like conversation,

31
00:02:12,770 --> 00:02:16,950
anticipate needs, and exceed expectations.

32
00:02:16,950 --> 00:02:21,770
Think of a time you were mad at your
computer for shutting down unexpectedly.

33
00:02:21,770 --> 00:02:25,940
Or at time a printer continuously claimed
there was a paper jam that you just

34
00:02:25,940 --> 00:02:27,420
couldn't find.

35
00:02:27,420 --> 00:02:30,160
And then spontaneously started printing

36
00:02:30,160 --> 00:02:32,880
after you simply jiggle
the paper tray a bit.

37
00:02:32,880 --> 00:02:36,638
You probably got annoyed, how rude of
their printer to behave like that?

38
00:02:36,638 --> 00:02:40,955
When products fail us we
have an emotional response.

39
00:02:40,955 --> 00:02:44,612
It's as if the inanimate object
has broken our trust, and

40
00:02:44,612 --> 00:02:47,160
our relationship with it is fractured.

41
00:02:48,320 --> 00:02:52,370
It's moments like these where
the fundamentals of interaction design

42
00:02:52,370 --> 00:02:55,090
enable us to empathize with the user, and

43
00:02:55,090 --> 00:03:00,230
preemptively designed solutions that
prevent frustration and broken trust.

44
00:03:00,230 --> 00:03:01,400
In the next video,

45
00:03:01,400 --> 00:03:05,860
I'll introduce the five dimensions that
form the foundation of interaction design.
