• What are Design patterns? • Why use them? • Patterns for interaction and navigation • How to sketch with patterns
DesignPatterns
3
• Solutions to recurring design problems
• Problem = conflicts between forces • Solution = Generic but immediately identifiable
configuration of features • At different levels of abstraction (information
architecture/top level of app vs how to place items on the screen or little things to remember)
Tidwell’sPatterns,egFeature,searchandbrowse

• What • put three elements on the first page, a featured item, a
search box, a list of the contents that can be browsed
• Use When • you have lots of content and users who want to browse or
search but also want to engage users immediately
• Why • people expect this, some want to search, some to browse and
you want to hook the user by providing something of interest immediately
• How, Examples

• Information architecture – the art of organising an information space
• Steering the user to the part that fulfils their goals • Single pages or screens do one of these things: • Show a single thing • Show a set of things • Offers tools to create something • Supports a task

Navigation
Navigation
21
• Sign posts helps people to understand their immediate environment
• Wayfinding is about getting closer to your goal • Good signage means clear and straightforward
labelling and calls to action • Cues in the environment builds on conventions • Maps provide a mental image of the entire
information and interaction space

Actions
Howdoestheuserinterfaceaffordactions?
53
• Menu bars • Pop-up menus • Dropdown menus • Buttons • Tool bars • Links • Action panels
• Hover on object • Double click object • Keyboard • Drag-and-drop • Written commands
• Gestures?
Typesofinteraction
54
• actions represented by interface object (menu-item, buttons, links etc), activated by clicking that object.
• direct manipulation on a more or less visible object (hover over, click-and-drag, double-klick, …)
• no visible component (swipe, pinch, keyboard shortcuts, command interfaces) • How to inform the user that there is an action
available when there is nothing to show? • combinations (scrollbars, levers etc)

Otheractionpatterns

• Prominent Done • Patterns for time consuming actions: • Preview - provide information on what the result
will be • Progress indicator • Cancel-ability
• Pattern for long sequences of actions: • Multi-level undo • Command history • Macros
InputForms
Principlesfordesigningaform
61
• Make sure that the user knows what to do and why • Avoid asking the question at all, if you can
• good defaults • Knowledge in the world is often more correct than knowledge in
the head • autocomplete and input hints
• Be as forgiving as possible for erroneous input • Watch out for literal translation of underlying programming
model • Usability testing • Choice of controls affects what users expect to do
ChoosingControls
62
• Space • Users’ computer skills • Users domain knowledge • Expectations based on other applications • Platform and operating system
Controls
63
• Look at what is available in the user interface guidelines for the platform: • iOS • Android • Windows • MacOS
Mobile
Challengesformobileplatforms
67
• Small screens • Different screen sizes • Touchscreens • Difficulties to input text • Challenging physical environment • Social factors and limited attention
DesignApproach
68
• What do the users really need in the mobile context? • Reduce the web site or app to its core • User the hardware of the mobile device • Align the content • Optimise for the most common action sequences • Reduce scrolling and side swiping • Reduce the number of taps

• http://www.ida.liu.se/~TDDC63/skissbok.pdf • Don’t apply it cookbook style • What is the feature that solves the problem? • Do more than one idea per pattern • Play around with the pattern
Varyingthepattern,ex:
77
• Accordion pattern (ch 4 Organising the page, p 159): What: Put items in a structure that collapses/hides unwanted subgroups.Use when: lots of heterogenous content that can be categorised but may be needed simultaneously Why: hiding unnecessary stuff eases cluttering while showing categories/titles allows recognising where to find stuff, allowing several sections to be visible simultaneously allows customisation. • a website for a flower seller: compose a bouquet • a CAD tool for mechanical engineering
