Gaia/Design/ApplicationUXDocumentation: Difference between revisions

* First Run

** Usually presents an Empty State

** Provides opportunity to prompt user to setup an account, etc.

** Can also be used to educate user via tutorials, tooltips, etc.

* Empty state

** Occurs when there is no content available.  

** Most commonly seen on app First Run.

** Also seen when user clears all content.

** To avoid user confusion ("Nothing is showing up. Is the app broken?") we can display a status and/or explanation. For example, a "No messages" string where a list might usually be.

* Error states

** Most common will be "no internet connection".  

** As with Empty State, we should avoid user confusion by communicating situation in UI.  

* Input Errors

** What happens when a user's form input fails?  

** Can communicate with:  

*** Inline-message (displayed alongside erroneous field)  

*** [[Gaia/Design/BuildingBlocks#Dialogue:_Banner|Banner dialogue]]

*** [[Gaia/Design/BuildingBlocks#Dialogue:_Prompt|Prompt dialogue]]

* Date & Time dependencies

** Is the app effected by user changing global Settings for Date & Time?

*** Time zones

*** Regions

*** Number formats

* Dependencies

** What hardware dependencies exist, and how do we flag them?

** eg: Music app could be dependent on SD card removable storage, and app could use [[Gaia/Design/BuildingBlocks#Dialogue:_Banner|Banner dialogue]] to communicate.

* Settings

** User preferences and settings that effect the operation of the application.

* Application data states

** How do apps display states for items?

** eg: Mail message states:

*** New

*** Unread

*** Read
