  • Part 1 What is “Feel”, and why should I care?
  • Look & Feel
  • Look & Feel
  • silk
  • water
  •

  •  
  • [photo of mouse and/or trackpad and/or Wacom tablet ] Feel: How you operate it with your hands

  •  
    • Q: What interactive elements to use?
    • Q: What interactive elements to use?
    • A: All of them
  •  
    • Q: What interactive elements to use?
    • A: Hmmm…
  • Feel affects:
    • Learning curve
    • Mental bandwidth needed to operate UI
    • User success (or errors)
    • Site personality
    • Brand promise
    • Adoption (or abandonment)
  • eBay Site Experience: a Holistic View
  • Feel
  • Part 2 What we did
  • Project phases
    • Strategy
    • Data Collection
    • Analysis
    • Recommendations
  • Project phase 1: STRATEGY
  • Ark of the Covenant A “compelling artifact”
  •  
  •  
  • Example flow: New user finds an item, bids for it, registers as member
  • Example flow: User bids on a Watched item, is outbid, rebids
  • Example flow: New seller lists item for sale, creates Seller account
  • Audit checklist
  • Project phase 2: DATA COLLECTION
  • FILE MAKER Ω Our FileMaker Pro database
  • Database Fields (partial list)
    • Very relevant:
    • Task & subtask
    • Step description
    • Page & URL
    • Action (syntactic)
    • Screen shot close-up
    • Instructional text
    • Click/keystroke record
    • Less relevant:
    • Region on page
    • Icons
      • symbol, meaning, behavior
    • Interface elements
      • label, type, style, notes
    • Comments on Feel
  • Project phase 3: ANALYSIS
  • Roll of Paper
  • Scrolls unrolled Flows as storyboards
  •  
  • Ideas for presenting findings
  • Radial charts to track Feel metrics
  • Emotional flow to track Feel effects
  • A course correction
  • Project phase 4: RECOMMENDATIONS
  • [DOCUMENT FORMAT SLIDE (FROM MY NOTEBOOK)]
  • Affordance Task Data Object
    • Affordance
    • A visual cue that some interaction is offered
    • Affordance Inconsistency
    • A single visual cue offering multiple interactions
  • Affordance Inconsistencies: Hyperlink User action… System response… Affordance Inconsistencies: Hyperlink Loads new page Clicks link… Immediate in-line response Clicks link…
  • Affordance Inconsistencies: Hyperlink User action… System response… Opens modal dialog box Clicks link… Expands/collapses in-line page content Affordance Inconsistencies: Hyperlink Clicks link…
  • Affordance Inconsistencies: Hyperlink Clicks link… Jump to anchor elsewhere on page Clicks link… Opens content in new browser window Affordance Inconsistencies: Hyperlink User action… System response…
  • Affordance Inconsistencies: Hyperlink Clicks link… Closes a popup layer Clicks link… Adds assistance frame to window User action… System response… Affordance Inconsistencies: Hyperlink
  • Affordance Inconsistencies: Tab Affordance Inconsistencies: Tab
    • Task
    • A path to accomplish an immediate goal
    • Task Inconsistency
    • A single goal accomplished via multiple paths
  • Task Inconsistencies: Filtering Data 1. Submit a form 2. Click tabs 3. Click criteria links 4. Click “toggle” link Task Inconsistencies: Filtering Data
  • 5 x Enable/Disable Form Section Inconsistencies Task Inconsistencies: Enable/Disable Section of a Form 1. Checkbox 2. Tabs 3. Dropdown menu 4. Radio buttons
    • Data Object
    • A representation of a data record or other piece of data
    • Data Object Inconsistency
    • A single data object represented multiple ways
  • Data Object Inconsistencies: Members CAPTURES Data Object Inconsistencies: eBay Member
  • Data Object Inconsistencies: Members Data Object Inconsistencies: eBay Member
  • The Interaction Audit report
  • Part 3 Actions & Future Directions
  • A page from the Interaction Audit
  • Interaction goals
    • Low learning curve, due to…
    • Consistent cues for actions
    • Predictable behavior of affordances
    • Instant recognition of interface elements
    • Allow eBay member content to shine
  •  
  • Clean-up teams
    • The Clickers links and buttons
    • The Swappers tabs and toggles
    • The Submitters forms and form elements
    • The Shufflers sorting and filtering
    • The Disclosers overlays and sections
  • An eBay design pattern
  • Clean-up process
    • Find problem area in the audit report
    • Recommend simpler set of interactions
    • Document as design patterns
    • Engineering creates code components
    • New and upgraded site areas use the cleaned-up interactions
  • What about interaction inconsistencies without obvious solutions? Example: Customize page layout
  • 6. Paired ordered lists w/buttons Task Inconsistencies: Customize page layout 3. Schematic picture with buttons 5. Hyperlinks 2. Dropdown menu 4. Form in floating dialog 1. Form on its own page
  • Basic requirements: restaurant Basic requirements: - Clean dishes & utensils - Courteous staff - Accurate check tabulation - No cockroaches
  • Site-specific values: restaurant Basic requirements: - Clean dishes & utensils - Courteous staff - Accurate check tabulation - No cockroaches Site-Specific Value: Marrying food and wine felicitously So must have: Comprehensive wine list Site-Specific Value: Joy in boundless variety So must have: Extensive menu Site-Specific Value: Convenience So must have: Speedy customer throughput
  • Basic requirements: interaction design Basic requirements: - Navigable interface - Orientation cues - Consistent basic interactions - No cockroaches
  • Site-specific values: interaction design Site-Specific Value: - Plethora of tools to help buyers - Compatibility So must have: - Dense pages - Progressive discovery Site-Specific Value: - Clean, friendly, safe - Tons of fun add-in applications So must have: - Transparency - Visual app framework Site-Specific Value: - Perceived simplicity - Convenient adding & editing of lists So must have: - Sparse pages - Direct manipulation Basic requirements: - Navigable interface - Orientation cues - Consistent basic interactions - No cockroaches
  • Values can vary depending on the conversation
  • “ Feel” metrics
  • Feel metrics: objective
    • Page dimensions
      • height, width
    • Number of interactive entities
      • Hyperlinks, buttons, form elements, icons
    • Interactive density
      • No. of interactive entities ÷ page size
    • “ Jack-in-the-boxiness”
      • No. of mouse-over elements ÷ page size
  • Feel metrics: semi-objective
    • Number of syntactic actions in a task
    • “ Reloadiness”
      • Latencies in response to interactions
    • Number/frequency of tool switches
      • Mouse to keyboard and back
    • Amount of dynamic behavior
      • Pop-up layers, video, “sponginess” (layout changes triggered by mouse-over)
  • Feel metrics: subjective
    • Number of different interaction styles, metaphors, paradigms in a page or task
    • Simplicity/complexity
    • Flatness/bumpiness
      • Flat = uses only hyperlinks & other primitives
      • Bumpy = uses more advanced interactions
    • Cognitive load
  • What we’ve learned
    • Nowadays it’s important to check “Feel”
    • An Interaction Audit can be compelling, actionable, and spark real improvement
    • Audits should focus on flows and be representative of real user experience
    • Simple tools work; storyboards are key
    • Audit for inconsistencies in Affordance, Task, and Data Object representation
    • Clean up obvious problems first
    • Harder problems require site-specific values
    • “ Feel” metrics may hold promise
