USER INTERFACES FOR MOBILE APPLICATIONS User Interface plays important role in

deciding the success of the app. The main goal of any app designer should be

making app a daily habit. 40% of app budget is allocated to user

interface design. The common mistakes of designing user

interface are placing buttons smaller in size, placing big or small images in different places and selecting wrong color patterns for views.

Clarity of interface is much required for any app.

User interface should follow standard native app interface standards.

IMPORTANT CONSIDERATION FOR USER INTERFACE

Expert vs novice users App should be efficient for expert user and it

should provide information to novice users

IMPORTANT CONSIDERATION FOR USER INTERFACE

Ideal button size The button size of app should be easily used by

user, if size is less then 1 cm then it is not used by user.

IMPORTANT CONSIDERATION FOR USER INTERFACE

UI Location Most UI Elements are placed at bottom or placed

at top. Most users hold phone and use thumb as primary

finger for touching. If user is right handed thumb will easily access

the bottom right of screen. If user is left handed thumb will easily Access the bottom left of screen

IMPORTANT CONSIDERATION FOR USER INTERFACE

Accounting for motion Flow direction plays important role in designing mobile

app. For example, for a right-handed person, circular flows

with a pivot point at the bottom right of the screen are much easier than linear flows

IMPORTANT CONSIDERATION FOR USER INTERFACE

How much is too much The button should be limited, if we place more

no of button then it will be tough even for expert user
