Make you users feel niceIntroduction toUser Experience Designing –Some Thoughts Amrit Sanjeev Bangalore Android User Group
About me• Co-organizer of the Bangalore Android User Group.• Research Engineer - Mobility Group at Philips R&D• Architect – Android platform development• Android hacker
How can we describe user experience ? “User Experience is the qualitative emotional description of multiple interaction with an object, in this case the user interface of a mobile application.”
How would you want to read news on your mobile ???
Do not confuse it with Interaction design• Interaction design is how the user would interact with the application .• Interface design is merely a method• User Experience is the relationship
Factors that affect UX MEMORY INPUT COMPUTATIONAL MECHANISM POWER NETWORK BATTERY LATENCYFORM FACTOR USER CONTEXT EXPERIENCE
Why is UX so important?• The application environment is like a space shuttle – Single early failure = non returning user• The first 30 -60 seconds usage is very important• The environment differs based on where you are
Layers of Mobile Experience PORTING Adapt for other devices that fit our strategy OPTIMIZATION Reduce all assets to its lowest possible size, memory footprint TESTING Test, test and test some more DEVELOPMENT Put all the pieces together PROTOTYPE Test the experience within the context DESIGN Create a user experience based on needs DEVICE PLAN Choose devices that best serve your audience STATEGY How can we add value to the business CONTEXT The circumstances where information adds value NEEDS & GOALS Identify the basic needs of our users IDEA We need an idea that inspires us
Elements of Mobile Design CONTEXT MESSAGE LOOK & FEEL LAYOUT COLOR TYPE GRAPHICS
Mobile context “Context is about the understanding human relationships to the people , places and things in the world”
Mobile context Why will Who are When will they user your they your app users ? interact? ? How are What is Where are they happenin the holding it g? users? ?
Message – what you are trying to say “Overall mental impression you create explicitly through visual design.”• How will someone react to your design?• What are your impressions of your design ?
Look & Feel• What you use to describe the appearance• Eg) clean look and feel or usable look and feel• “What does it mean?”
Layout• How the user will visually process the page ?• The structural and visual components of layout often get merged together, creating confusion and making your design more difficult to create.
Color• Create and maintain brand identity• Common problem : When complex designs are displayed on different mobile devices, the limited color depth on one device can cause banding, or unwanted posterization in the image.
Typography• Try out custom typography styles . It will make a huge difference• subpixel-based screens – – division of each pixel into a red, green, and blue (or RGB) unit at a micro- scopic level, enabling for a greater level of antialiasing for each font character or glyph• How type is rendered on mobile screens: – pixel density or greater pixels per inch (PPI)
Graphics• Use of images that are used to establish or aid a visual experience.• Graphics can be used to supplement the look and feel, or as content displayed inline with the text. – Iconography – Photos & Images
Mobile Environment• Single early failure = non returning user• First 30 ~ 60 seconds usage is critical• Environment changes depending on where you are• Data Snacking ( small snippets, simple but repetitive and regular )• Reuse learnt behavior
Mobile Environment• Mobile is NOT about making things smaller Miniaturisation vs Mobilisation• Fewer options = simple and more effective interface• Decide the default states in UI to maximize impact
Mobile Environment• Faking it – Increasing responsiveness – Immediate visual changes while processing is happening in backgroud• Keep it simple ( the real hard part ) – Increases user comfort – Sense of exploration increases
Conclusion What comprises of a great mobile experience? Experiences are uniquely mobile Is sympathetic to context Exploit the power of mobility
