Common sense

The best camera is the one you have with you when something interesting happens


Jakob Nielsen

The best computer is the one you have with you when you want something done. This will often be your phone or tablet


Mobile devices

Mobile devices have become pervasive

Most people carry one, have them turned on almost continuously and use them in different contexts


Mobile devices


Mobile devices

The design is dominated by the screen

Multi-touch based interactions

The device becomes the content

Always on, always connected


Mobile devices

Attend to…Informational needs

Geographical needs

Personal information management needs


Mobile devices

Informational needs are focused on the goal of obtaining information about a topic“Is the Arsenal game on TV tonight?”


Mobile devices

Geographical needs are focused on the goal of finding an answer to a question

The expected answer is dependent on location in some form“Nearest Pennies or Dunnes Stores”

“Where do I get coffee?”

“Direction from Belfast to Randaldstown”


Mobile devices

Personal information management needs are focused on finding out something private relating to the individual

Personal information management needs encompass personal items, friend requests, scheduling tasks and to-do list items“What are my airline loyalty pin codes?”


Mobile devices

The mobile phone and other personal mobile devices have gained a new role

A gateway to data and applications which are stored on the network


Part 2Interaction design


Interaction design


Interaction design

So, what to consider when designing mobile applications?


Interaction design

Native, web application or both?Native applications

Provide a richer experience

Integrate with various operating system features

Need to be approved in the App Store

Web applicationsCan be used on a multitude of platforms

Don’t need to be approved in the App Store

Functionality is limited, because they only work in the browser


Interaction design

What features of the mobile device does your application need to use?

Does it need to work offline?

How are people going to use your app?

How much will it cost?

Do you need to support various screen sizes?


Interaction design

In any case…Following UI conventions

Human interface guidelines

Don't break existing patterns

Design for touch interaction


Part 3Developing a concept



Developing a concept

The application conceptWhat does your application do?

Who is your target audience?

How will people use your application?

How much will the application cost?



And how do we describe a concept?Using a concept map!

But, what is a concept map?A diagram showing relationships between concepts

Represents relationships between ideas

Makes it easier to communicate ideas in teams

Surfaces strengths and weaknesses of ideas

Basically, just boxes and arrows



And how do we build a concept map?Identify a focus question

Identify 10 to 20 concepts that are related to the focus question

Begin to build your map by placing the most inclusive, most general concept(s) at the top

Select two, three, or four sub-concepts to place under each general concept

Connect the concepts by arrows

Label the lines with or a few linking words

Look for crosslinks between concepts in different sections of the map and label these connections
