Most key concepts well represented

Visibility a bit low

eli_2450: Interesting read. Actually ran into a lousy door today that had a handle, suggesting us to pull it, but could only be pushed

Cornell Doors!… Everydayness

imorse2450: Gates Hall has the worst case of Norman doors I've ever seen.

Could you make these visible to us ??

jhubbard2450: Does natural mapping change from generation to generation? For ex. the mapping of a landline is much different than an iPhone

The generation gap

JMcManus2450: Gaps in age greatly influence some conceptual models. My mom and I have very different ideas about how our Iphones operate.

EGonzalez2450: The problem in human centered design is differences in users. Is there a way to make design more intuitive for all users?

Provocative Questions

rpicard2450: Won't tailoring design toward 'understanding' inhibit users using products in creative ways? Intended use isn't always best...

Chapter 1 – The Psychopathology of Everyday Things

• everyday objects filled with design issues

• we interact with them deeply, unconsciously, constantly

• typically people blame themselves

• good design is rare but achievable

Everyday-ness

mrothstein2450: the ultimate goal of an interactive device should be user-friendliness without making users feel like they are being babied

Affordances

• perception informed by culture and habit are important•But physical can also be sufficient

High-Level Principles

Everyday-ness

cboutwell2450: It's interesting to think how being overly logical can make design less user friendly. I've always thought logical == simple.

Affordances are less logical, more “gut feel”

Page 20: 2450 f15 02-norman1_as_delivered

Chapter 1 – The Psychopathology of Everyday Things

Affordances

• origins at Cornell with J.J. Gibson – interactive possibilities

• perceived and actual properties of how a thing could possibly be used

• “clues” to use

Visibility

• we are visual creatures – often fastest perception

“visual first, think later”

Visibility” often means salience – noticeability

High-Level Principles

ddaniels2450: Could a design have too many signifiers and as a results the person becomes more confused or frustrated with the design?

Page 22: 2450 f15 02-norman1_as_delivered

Visibility

• we are visual creatures – often fastest perception

Breakout

• - identify an everyday virtual or physical object• - analyze in terms of affordances and visibility• - write out points, include your names, pass to TAs

ikaplan2450: An example of unintended, but helpful feedback is the sound of a car engine starting. The user then knows the car started.

Conceptual Models

A set of mappings between controls and functions…

… that are guided by a simple set of principles or overarching logic

Conceptual Models

Page 40: 2450 f15 02-norman1_as_delivered

Conceptual Models

People will make sense out of any information you give them

This is bad, because they jump to all kinds of crazy conclusions

But this is also good, because it means they can be easily trained to understand new technology with the right affordances and signifiers as cues

Design Models and User Models

Do they work in exactly the same way?

Are there clues to how they are different?
