Lesson 5: UI Mobile Components and Patterns Flashcards
Resistive screens are made up of how many layers of what?
two layers of conductive material with a gap between them to serve as resistance.
What is a capacitive touchscreen?
A capacitive touch screen is a control display that uses the conductive touch of a human finger or a specialized device for input.
Haptic screens provide what?
Provides tactile feedback to the user when they touch the glass.
What does AMOLED stand for?
Active-Matrix Organic Light Emitting Diode
TFT
Thin Film Transistor. Screens that offer reasonable resolution but are power intensive.
IPS-LCD
In Place Switching Liquid Crystal Displays. Offers improvements in both resolution and power consumption.
The retina screen is an IPS-LCD.
OLED
Organic Light Emitting Diodes.
GPS
Global Positioning System
Accelerometer
measures the speed of movement of the device and the direction in which the device is moving.
This enables the pedometer function common in many health apps as well as other more ingenious uses of motion data.
What is a Mobile Splash Screen?
The splash screen is the very first screen that a user sees when they open up your app on their smartphone or tablet.
Both Google and Apple have developed guidelines for mobile apps and both of them say that there’s a specific use for splash screens in mobile apps. That is to give the user the impression that their app has loaded faster than it actually has.
In addition, you ought to indicate that this is a loading screen to ensure the user doesn’t become frustrated pushing buttons on the splash screen.
What do the operating system developers say is the best use for mobile splash screens?
To make users think the app has loaded more quickly than it has
What are splash screens often used for in games and desktop applications?
To market to users and to improve brand visibility
To make users feel welcome
KISS
Keep it simple stupid
What needs consideration when designing user profiles?
Privacy
Gyroscope
A gyroscope is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself.
When should you collect user data on mobile?
Only when the data is essential
What is the most common way to allow a user control over a map surface area?
Scrolling and panning
What is the guideline size for a touch point?
36 px X 36 px
How long should it take for a single screen summary to “just vanish”?
5sec
8 common patterns that are applied to mobile search
Auto-Complete Dynamic Search Explicit Search Faceted Search Saved and Recent Scoped Search Search Forms Search Results
Dynamic Search
Dynamic search uses a form of filtering, so that when a user begins to enter data – the content already on the screen is filtered based on the search field. This can be very useful when a user is trying to wade through large volumes of data – for example, a list of hotels in a certain area.
Explicit Search
This type of search requires an action from the user to start the search; such as tapping a button on the display or perhaps using a keyboard control. Results from the search will, normally, be shown directly below the search bar.
Faceted Search
Faceted Search is a more complex version of scoped (or filtered) search. It tries to deliver a huge number of search filtering criteria and allows the use of multiple filters to narrow down huge data sets. This is commonly implemented in a tray pattern that enables a user to set filters without having any prior knowledges of Boolean logic.
Saved and Recent
This search pattern recognizes that users often want to return to a search that they have used in the past. It allows the user to save their searches (or does this automatically on behalf of the user) and then to recall these searches at a later date.
Scoped Search
A scoped search allows the user to define criteria for the search before they begin their search. For example, Google allows users to choose between image searches, web searches, news searches, etc. before entering the data.
Search Forms
If you need a variety of data to conduct a search, for example if you ran a flight booking service – you might need to know the date of departure, date of return, number of people flying, seat preferences, destinations, etc. then you can use a simple form to collect all the data to deliver quality search results.
What is a complex form of filtered searching?
Faceted searching
Which is a form of filtering based on the current status of input in the search field?
Dynamic Searching

What does VIP stand for in mobile UX design?
Visual, Interruptible and Playful
