Question 10

What is a Mobile Splash Screen?

Answer 10

The splash screen is the very first screen that a user sees when they open up your app on their smartphone or tablet.

Question 20

8 common patterns that are applied to mobile search

Answer 20

Auto-Complete
Dynamic Search
Explicit Search
Faceted Search
Saved and Recent
Scoped Search
Search Forms
Search Results

Question 21

Dynamic Search

Answer 21

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.

Question 22

Explicit Search

Answer 22

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.

Question 23

Faceted Search

Answer 23

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.

Question 24

Saved and Recent

Answer 24

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.

Question 25

Scoped Search

Answer 25

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.

Question 26

Search Forms

Answer 26

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.
