Understanding the device | POD04


The first 5 seconds of a users interaction with an app are the most important. They are the building blocks and show the user how to use the app.

Simple gestures become second nature like tapping and swiping.

The tap –  gesture is the most common and simplest gesture. The standard area for a simple touch on a screen is a 44 by 44 pixel area.
The drag – is used mainly for scrolling or moving objects like apps.
The flick – is designed for a less direct movement.
The swipe – allows the user to access hidden, touch heavy elements.
The pinch – can be used to scale images or objects.


iOS has guidelines or requirements for designing you app. Almost all iOS apps use similar toolkit features in their apps such as navigation bars, tab bars, toolbar buttons, segmented controls, map view and alerts. These features fall into 4 main categories – Bars, Content views, Controls, Temporary views. iOS have different keyboard types depending on the context off the app. Such as for entering a phone number, the numbered keyboard will display, typing an email will prompt the keyboard to have the ‘@’ key accessible without having to dig into menus to find it.

Understand each platform that you’re working for (IOS and Android). Ask your friends “What was the first thing you did when you got your iPhone?”
Common UI elements: Bars, Content views, Controls, Temporary views.
Aim to keep keyboard use to a minimum, allowing the user to use gestures like swipe, tap etc instead. Take into account the position of the interface elements and where they are relative to a user’s finger and reach.
