    • Q: What interactive elements to use?
    • Q: What interactive elements to use?
    • A: All of them
  26.  
    • Q: What interactive elements to use?
    • A: Hmmm…
  28. Feel affects:
    • Learning curve
    • Mental bandwidth needed to operate UI
    • User success (or errors)
    • Site personality
    • Brand promise
    • Adoption (or abandonment)

  31. Part 2 What we did
  32. Project phases
    • Strategy
    • Data Collection
    • Analysis
    • Recommendations
  33. Project phase 1: STRATEGY
  34. Ark of the Covenant A “compelling artifact”
  35.  
  36.  
  37. Example flow: New user finds an item, bids for it, registers as member
  38. Example flow: User bids on a Watched item, is outbid, rebids
  39. Example flow: New seller lists item for sale, creates Seller account
  40. Audit checklist
  41. Project phase 2: DATA COLLECTION
  42. FILE MAKER Ω Our FileMaker Pro database
  43. 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
  44. Project phase 3: ANALYSIS
  45. Roll of Paper
  46. Scrolls unrolled Flows as storyboards
  47. Ideas for presenting findings
  48. Radial charts to track Feel metrics
  49. Emotional flow to track Feel effects
  50. A course correction
  51. Project phase 4: RECOMMENDATIONS
  52. [DOCUMENT FORMAT SLIDE (FROM MY NOTEBOOK)]
    • “ Affordance”
    • A visual cue that some interaction is offered
    • “ Affordance Inconsistency”
    • A single visual cue offering multiple interactions
  54. Affordance Inconsistencies: Hyperlink User action… System response… Affordance Inconsistencies: Hyperlink Loads new page Clicks link… Immediate in-line response Clicks link…
  55. Affordance Inconsistencies: Hyperlink User action… System response… Opens modal dialog box Clicks link… Expands/collapses in-line page content Affordance Inconsistencies: Hyperlink Clicks link…
  56. 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…
  57. Affordance Inconsistencies: Hyperlink Clicks link… Closes a popup layer Clicks link… Adds assistance frame to window User action… System response… Affordance Inconsistencies: Hyperlink
  58. Affordance Inconsistencies: Tab Affordance Inconsistencies: Tab
    • “ Task”
    • A path to accomplish an immediate goal
    • “ Task Inconsistency”
    • A single goal accomplished via multiple paths
  60. Task Inconsistencies: Filtering Data 1. Submit a form 2. Click tabs 3. Click criteria links 4. Click “toggle” link Task Inconsistencies: Filtering Data
  61. 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
  63. Data Object Inconsistencies: Members CAPTURES Data Object Inconsistencies: eBay Member
  64. Data Object Inconsistencies: Members Data Object Inconsistencies: eBay Member
  65. The Interaction Audit report
  66. Part 3 Actions & Future Directions
  67. A page from the Interaction Audit
  68. 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
  69.  
  70. 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
  71. An eBay design pattern
  72. 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
  73. What about interaction inconsistencies without obvious solutions? Example: Customize page layout
  74. 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
  75. Basic requirements: restaurant Basic requirements: - Clean dishes & utensils - Courteous staff - Accurate check tabulation - No cockroaches
  76. 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
  77. Basic requirements: interaction design Basic requirements: - Navigable interface - Orientation cues - Consistent basic interactions - No cockroaches
  78. 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
  79. Values can vary depending on the conversation
  80. “ Feel” metrics
  81. 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
  82. 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)
  83. 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
  84. 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
