Some reminders
• Products are for people • People have limited… – Vision – Cognition – Memory
• People act and respond in certain ways – (but not all people are the same)
• For people, UI = product
From Code to Product Lecture 4 — UI Design— Slide 3 gidgreen.com/course
Lecture 4
• The design process • Common examples – User registration – Search
• Books and tools
From Code to Product Lecture 4 — UI Design— Slide 4 gidgreen.com/course
RememberTheBirthdays.com
• Birthday reminder website – Also: anniversaries, holidays
• Basic service is free – Pay to send greeting cards
• Easy to enter birthdays – Imports from Facebook
• Reminders by email or SMS
From Code to Product Lecture 4 — UI Design— Slide 5 gidgreen.com/course
The process
• User and scenario • Entities, properties, actions • Grouping • Initial sketches • Key paths • Other paths • Visual design
From Code to Product Lecture 4 — UI Design— Slide 6 gidgreen.com/course
User and scenario
• Who would use it? – Who wouldn’t?
• What’s their goal? • When and where? • What devices? • How do they think? • What skills?

Building a user profile
• Identify users – Age, gender, country, education
• Interviews – How do they do it now? – Propose the idea
• Observation – Using something similar
• Stereotypes From Code to Product Lecture 4 — UI Design— Slide 8 gidgreen.com/course
Avoiding stereotypes
From Code to Product Lecture 4 — UI Design— Slide 9 gidgreen.com/course
User goals
• Experience goals (feel) – Feel in control – Sense of achievement
• End goals (do) – Stop forgetting birthdays – Get great gifts
• Life goals (be) – Be loved by friends and family
From Code to Product Lecture 4 — UI Design— Slide 10 gidgreen.com/course
RTB.com Entities
• The user • Other people • Recurring events – Birthdays – Anniversaries – Holidays
• Event instances • Greeting card

Other paths
• Forgot my password • Deleting an event • Finding a person by name • Printing a calendar • Sharing data with other users • Change mobile number
From Code to Product Lecture 4 — UI Design— Slide 26 gidgreen.com/course
Visual design
• After functional design • Sketch a few options – Much more subjective
• Communicate right message • Apply consistently over screens • Beware: it’s a time sink – Users don’t care that much

To keep in mind
• Design for a specific user – Deal with variants later on
• Avoid inventing paradigms – Example: The 3D fantasy
• Study popular products – But don’t rip them off
• Constantly collect feedback • With time, it gets faster
From Code to Product Lecture 4 — UI Design— Slide 30 gidgreen.com/course
Lecture 4
• The design process • Common examples – User registration – Search
• Books and tools

No username!
Hotmail
From Code to Product Lecture 4 — UI Design— Slide 34 gidgreen.com/course
To username or not to username
From Code to Product Lecture 4 — UI Design— Slide 35 gidgreen.com/course
Advantages Disadvantages
Can be 100% permanent Another field at registration
Semi-anonymous identity for user interactions Likely to be forgotten
May provide additional useful information
Prevents detection of wrong email addresses
Natural way to address user Can be inappropriate
Two users want the same one
CAPTCHAs
• Prevent automated scripts • Based on the Turing test – Easy for humans, hard for computers
• Problems – Accessibility – Can be hard for regular people – Bypassed with cheap labor ($0.001)
• reCAPTCHA

Navigational search
From Code to Product Lecture 4 — UI Design— Slide 55 gidgreen.com/course
Autosuggest
From Code to Product Lecture 4 — UI Design— Slide 56 gidgreen.com/course
Autosuggest sources
• Database of matches – Most relevant matches with prefix
• Behavior of all users – Most common searches with prefix
• Behavior of this user – Searches closest to user’s activity

Search results page
From Code to Product Lecture 4 — UI Design— Slide 59 gidgreen.com/course
Search results page
From Code to Product Lecture 4 — UI Design— Slide 60 gidgreen.com/course
Ranking factors
• Number of matches • Location of match • Importance of result • Previously visited by user? • User’s other previous activity • Click-throughs of other users • Date
From Code to Product Lecture 4 — UI Design— Slide 61 gidgreen.com/course
Combining factors
• Multiplicative – Score = Relevance × Importance
• Probabilistic principle – P(relevant to user | user search)
• But consider spread – P(at least one result is good | …)
• This stuff is really hard…
