Springboard

• Use a grid layout grid layout grid layout grid layout for items of equal importance, or an irregular layout to emphasize some items more than othersirregular layout to emphasize some items more than others

• Consider personalization and customization options

Lists

• Work well for long with subtext

• All internal screens should have a way for returning back

• It can be “infinite”, it can have thumbnails

Tabs

• Clearly differentiatedifferentiatedifferentiatedifferentiate the selected tab from the others

Gallery (Grid)

Dashboard

• Usually Springboards are also called Dashboards

Metaphor

• Pages are modeled to reflect the application’s metaphormetaphormetaphormetaphor

• Use the Metaphor pattern judiciously

Page carousel

• Works best for navigating a small number of pages

• Visual indicator Visual indicator Visual indicator Visual indicator to reflect the number of screens, and current screen current screen

• FlickFlickFlickFlick to navigate the carousel

Image Carousel

Expanding Lists

• Works best for progressively disclosing more details progressively disclosing more details progressively disclosing more details progressively disclosing more details or options for an objectoptions for an object

Infinite Area

• The entire data set can be considered to be a largelargelargelarge, two-dimensional graphicdimensional graphic

• The viewport shows only a small

subset of the whole data set

• Remark what is being shared

Empty datasets

• Avoid white-screens, explain why the dataset is empty

• call for action, only one!

• Avoid error messages• Avoid error messages

Multi Step

• Show the user where they are and where they can go

• Eliminate unnecessary fields

• minimize the number of pages and steps

Settings

• Put them inside the app

• Clear and grouped

• Easy to be understood

Search, Sort & Filter

• Search– Explicit Search– Explicit Search

– Auto-complete

– Dynamic Search

– Scoped Search

– Saved & Recent– Saved & Recent

– Search form

– Search Results

Explicit Search

• Offer a clear button clear button clear button clear button in the field

• Provide an option to cancel option to cancel option to cancel option to cancel the search• Provide an option to cancel option to cancel option to cancel option to cancel the search

• Use feedbackfeedbackfeedbackfeedback to show the search is being performed

Search Auto-complete

• Show feedback Show feedback Show feedback Show feedback if there could be a delay in displaying the results

• Consider emphasizing the matching search text emphasizing the matching search text emphasizing the matching search text emphasizing the matching search text in the search • Consider emphasizing the matching search text emphasizing the matching search text emphasizing the matching search text emphasizing the matching search text in the search results

Dynamic Search

• AutomaticallyAutomaticallyAutomaticallyAutomatically filtersfiltersfiltersfilters a given list of items

• Works well for constrained data setsconstrained data setsconstrained data setsconstrained data sets, like an address book • Works well for constrained data setsconstrained data setsconstrained data setsconstrained data sets, like an address book or personal media library

Scoped Search

• Offer reasonable scoping options scoping options scoping options scoping options based on the data set

• 3 to 6 3 to 6 3 to 6 3 to 6 scoping options are plenty

Search form

• Minimize the number of input fieldsMinimize the number of input fieldsMinimize the number of input fieldsMinimize the number of input fields

• Follow form design best practices form design best practices form design best practices form design best practices (alignment, labels, size)

• Use only when strictly

needed

Search Results

• Use live scroll live scroll live scroll live scroll instead of paging

• Apply a reasonable default sort orderdefault sort orderdefault sort orderdefault sort order

this is also an Anti-pattern(see Oceans of Buttons)

Search, Sort & Filter

Filter Forms

• Don’t over-design the filter, a simple onscreen filter or drawer will usually sufficedrawer will usually suffice
