For disappearing acts, it's hard to beat what happens to the eight hours supposedly left after eight of sleep and eight of work. ~Doug Larson

Things are not always as they seem

3 Concepts in Time Perception Make it appear faster Make it faster Make it tolerable


Слайд 11

MAKE IT FASTER Performance vs. Responsiveness Benchmarks/Standards Weber Ratio (JND)


Слайд 12

MAKE IT APPEAR FASTER Psychological Time Perception vs. Reality Pliancy


Слайд 13

More than meets the eye


Слайд 14

TOLERANCE Inaccurate / Subjective Vierordt’s Law Relative


Слайд 15

PERCEPTION Service = Minus Expectation


Слайд 16

PLAY It’s Hard too Catch-up Ball


Слайд 17

TOLERANCE THRESHOLDS .5 – 1.0 sec. = Immediate .1 - .2 sec. = Instantaneous 10 -12 sec. = Attention (single task) 2 – 5 sec. = Continuous


Слайд 18

Humans & Computers 2


Слайд 19

HCI is Communication


Слайд 20

WHAT IF HCI MIMICKED OUR OWN INTERACTIONS?


Слайд 21

THEY WOULD How long it will take Tell us input is received Manage tasks in background


Слайд 22

THEY WOULD ALSO Anticipate common pathways Free us for other tasks Simply respond and reassure


Слайд 23

OUR RELATIONSHIPS


Слайд 24

12 Techniques & Applications 3


Слайд 25

1. Create User Flow


Слайд 26

User Control Challenge Users Goals & Feedback 1 2 3 USER FLOW


Слайд 27

Challenge Skills Match Vary Skill Levels Beginner vs. Expert Software Modes / Preferences


Слайд 28

GIVE USERS SENSE OF CONTROL Forgiveness Provide Options Undo, Escape Hatches, Back Buttons


Слайд 29

“the flow experience is typically described as involving a sense of control – or more precisely as lacking the sense of worry about losing control.” ~ Mihaly Csikszentmihalyi


Слайд 30

Minimize Interruptions


Слайд 31

AVOID ANXIETY


Слайд 32

AVOID UNCERTAINTY


Слайд 33

GOALS & FEEDBACK Precise Language Prompt Feedback Trim Information & Descriptive Buttons


Слайд 34

Hick-Hyman Law


Слайд 35

2. Use Time Anchors


Слайд 36

Time Anchor Matrix


Слайд 37

USING TIME ANCHORS “Installation will be between 3 and 5 minutes” “The download will take about 30 seconds” “Time remaining: 10 minutes”


Слайд 38

TIME ANCHOR USE Ranges prevent users from holding us to exact numbers Never skip over a number when representing ranges Use anchors for countdown units in timers


Слайд 39

3. PROGRESS INDICATORS


Слайд 40

PROGRESS INDICATOR - GENERAL GUIDELINES 0-2 Seconds - No Indication Needed 2-5 Seconds - Busy Animation 5-X Seconds - Progress Indication Needed 10+ Seconds - Cancel Button


Слайд 41

PROGRESS INDICATOR DESIGN Avoid Time Elapsed Time vs. Work Units Never Increase Time Unit Increments


Слайд 42

NO SPECIFICITY


Слайд 43

BE SPECIFIC Never start at zero How long will it take? Use time anchors


Слайд 44

DESCENDING DURATIONS & NONLINEAR PROGRESS BARS


Слайд 45

FINAL COUNTDOWN


Слайд 46

4. PREEMPTIVE START


Слайд 47

No clear start or end time – less ability to estimate duration


Слайд 48

5. EARLY COMPLETION & INVISIBLE DECONSTRUCTION Finish details & deconstruct in background Ends process early


Слайд 49

6. CONTINUOUS DURATIONS Avoid segmentation of processes Get input upfront & automate process Fire & Forget!

Слайд 52

7. MEANINGFUL DIVERSION

Слайд 55

8. WORTH THE WAIT


Слайд 56

WOULD WAIT AGAIN


Слайд 57

THEY WILL WAIT AGAIN


Слайд 58

9. UNDERSCORE VALUE


Слайд 59

10. SET EXPECTATIONS & EXCEED THEM


Слайд 60

11. OFFER CONTEXTUALIZED FEEDBACK Your system does not meet the minimum requirements


Слайд 61

TIME PERCEPTION 12. INCLUDE IN DESIGN & TESTING PROCESS


Слайд 62

METHODS TESTING ROOT CAUSE EXPERT REVIEW


Слайд 63

SUMMARY MODEL REAL WORLD TIME = SUBECTIVE INTEGRATE INTO DESIGN


Слайд 64

“When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute – and it's longer than any hour. That's relativity.” ~Albert Einstein
