Apps usable for everyone?

Application Definiton Statement

{your differentiator} {your solution} for {your audience}

ADS„ ... pick the few features, most frequently used, by the majority of your users, most appropriated for the mobile ...“

{easy to use} {digital photo sharing} for {casual iphone users}

Example:

{easy to use} {digital photo sharing} for {professional iphone users}

Note - this is a new app

• Elegant solution: you must solve a user's problem and solve it eleganty

• Great usability: solide app hierarchy, clean layout

• Gorgeous application icon: hey, the icon is the brand of your product!

iPhone - HI Guidelines

Planning your iPhoneSoftware Product

Designing the UserInterface of youriPhone Application

iPhone OS PlatformRich with Possibilites

http://www.flickr.com/photos/shuffle-art/1441940051

Platform Differences 1/2„An iPhone OS-based device is not a desktop or laptop computer, and an iPhone application is not the same as a desktop application.“

• The display is paramountCompact Sreen Size - 480*320 pixels (iPhone 3 and lower), 960*640 pixels (since iPhone 4), 1024*768 pixels (iPad)

• Device orientation can change to any time

• Memory is not unlimted

• Apps Respond to gestures, not clicks

• One screen at a time

Platform Differences 2/2„An iPhone OS-based device is not a desktop or laptop computer, and an iPhone application is not the same as a desktop application.“

• Preferences are available in settings

• Apps have a more or less just on single window

• Minimal User Help

What Are Your Options?„Depending on the implementation details and its intended audience, some types of software may be better suited to your needs than others.“

• An iPhone Application (available in App Store)

• Web-only Content (compare http://itunes.tugraz.at): - Web Application - Optimized webpage - Compatible webpage

• Hybrid Applications (access to web content)

3 Application Styles„... applicaton styles, based on visual and behavioral characterstics, data model, and user experience.“

• What do you expect to be the user‘s motivation for using the application?

• What do you itend to be the user‘s experience while using the application?

• What is the goal or focus of the application?

• How does the application organize and display the information people care about?

Productivity Applications„ ... enables tasks that are based on the organization and manipulation of detailed information“

• Organizing the list

• Adding and subcontracting

• Drilling down, performing tasks on reached level

Utility Applications„ ... perfoms a simply task that requires a minimum of user input.“

• visually attractive

• enhancement of information display

• Organize of information into a flattened list of items; no hierachy

Immersive Applications„ ... offers a full-screen, visually rich environment that‘s focused on the content and the user‘s experience with that content“

• tends to hide much of device‘s user interface

• use of nonstandards controls appropriate

• information presentation in the context of game-play, story or experience

Choosing an App Style

„When in doubt, keep it simple.“

• Pare the feature list to the minimum

• To bring ideas from you desktop application to an iPhone application, apply the 80-20 rule (the largest percentage of users will use a very limited number of features)

• Find the core tasks

Case Study: Mail„ ... when people are mobile, their needs for an email application are simpler, and they want access to core functionality quickly.“

Design the App For the Device„... you need to make sure that your app looks and feels like it was designed expressly for an iOS-based device.“

• Embrace iOS UI paradigms (controls should look tappabel, App structure should be clean, ...)

• Ensure that unvirsal apps run well on both(iPhone and iPad)

• Reconsider web-based designs

• Tailor customization to the task

• Prototype and Iterate

From iPhone to iPad Application

iPad Human Interface Guidlines - Martin Ebner 2010

Compatibility Mode„Unmodified, iPhone applications are running in a compatibility mode on iPad, but it does not give them the device-specific experience they want.“

• Games and other immersive iPhone applications may not need much change in information architecture, because they are experience driven. In general they need a siginificant revision of artwork and interaction.

• iPhone productivity applications tend to require some rearchitecting of the information hierachy, in addation to an enriched UI and an enhanced user experience.

• Utility applications need be reenvisioned for iPad so that they can take advantage of the larger screen.

Human Interface Principles

http://www.flickr.com/photos/wonderlane/4315076635

Great User Interface„ ... follows human interface design principles, that are based on the way people think and work, not on the capibilities of the device.“

• Methaphors (playback control, sliding on-off switching, ...)

• Direct Manipulation (with the Multi-Touch Interface)

• Consistency (application has to take the standards)

• Feedback (must be immediate)

• User Control (user, not the application must initiate and control actions)

• Asthetc Integrity (how well the appearance of you application integrates with your functionality)

User Experience Guidelines

http://www.flickr.com/photos/rivalee/2939042459

Focus on the Primary Task„An iPhone Application that establishes and maintains focus on its primary functionality is satisfying and enjoyable to use“

• What is most important in each context?

• Is the provided information essential, does a user need this information right now?

Build in Simplicty/Ease of Use„ ... users are probably doing other things while they simultaneously use your application“

• Elevate the content that people care about

• Think Top Down - High level Information near the top of the screen (independent of how people tap on screen, top is most visible)

• Minimize text input and Keep essential information succinctly

• Give people a logical path to follow

• Provide a fingertip-size target area for all tappable elements (calculator example: 44*44 pixel)

Communicate Effectively

„ ... avoid technical jargon in the user interface“

• Feedback is important

• use user-centric terminology

Support Gestures Appropriately„To ensure that your application is discoverable and easy to use, therefore, try to limit the gestures you require to the most popular.“

Think about each detail

„ ... iOS devices are personal devices, but ...“

• Downplay File-Handling Operations

• Enable Collaboration and Connectedness

• De-emphasize Settings

• Brand appropriately

• Make search quick and rewarding

• Use UI Elements consistently

Graphical Interface - don‘t forget about it„ Rich, beautiful, engaging graphics draw people into an application and make the simplest task rewarding....“

• Consider Adding Physicality and Realism

• Delight People with Stunning Graphics

• Use subtle Animation to communicate

• Ask People to save only when necessary

For iPad 1/2

• Enhance Interactivity

• Reduce Full-Screen Transitions (update only the areas of the UI that need it)

• Restrain your information hierachy (more information in just one place)

• Migrate Toolbar Content to the Top

For iPad 2/2

• Does the task require more than one type of input?

• Does the taks require people to drill down through a hierachy of views?

• Might people want to somethingin the main view before theyfinish the task?

• Is the task fairly in-depth and does it represent one of theapplication‘s main functions?

„Consider Using Popovers for some modal tasks...“

iOS Technology Usage Guidlines

http://www.flickr.com/photos/intherough/4263146374

iCloud Storage„iCloud storage helps people access the content they care about regardless of which device they are currently using.“

• Respect the user‘s iCloud account

• Determine which types of information to store

• Make sure your app behaves reasonably when iCloud storage is unavailable

• Avoid asking users to choose which documents to store

• Warn users about the consequences of deleting a document

• Be sure to include the user‘s iCloud content in searches

Multitasking„ Multitasking allows people to switch quickly among recently used applications, because apps can be suspended in the background when they are quit.“

• Be ready for interruptions, and ready to resume

• Make sure your UI can handle the double-high status bar

• Be ready to pause activities that require people’s attention or active participation

• Ensure that your audio behaves appropriately

Multitasking„ Multitasking allows people to switch quickly among recently used applications, because apps can be suspended in the background when they are quit.“

• Use local notifications sparingly

• When appropriate, finish user-initiated tasks in the background.

Notification Center 1/2„... gives a user a single, convenient place in which to view notifications from their apps.“

• Keep badge contents up to date

• Don‘t send multiple notifications for the same event

• Provide a custom message that does not include your app name

• Provide a sound that users can choose to hear when a notification arrives

Notification Center 2/2„iOS apps that support local or push notifications can use the following notification styles.“

Banner

BadgeAlert

Printing„ ... users can wirelessly print content from your application“

• Use the system-provided Action button

• Display the Print item when printing is a primary function in the current context

• If appropriate, provide additional printing options to users

• Don’t display print-specific UI if users can’t print

iAd„ ... you can allow advertisements to display within your application and you can receive revenue when users see or interact with them“

• size 320*50

• Place the banner view at or near the bottom of the screen

• Ensure that banner views appear when it makes sense in your application

• As much as possible, display banner ads in both orientations

iAd„ ... you can allow advertisements to display within your application and you can receive revenue when users see or interact with them“

• Don’t allow an ad to scroll off the screen

• While people view or interact with ads, pause activities that require their attention or interaction

• Don’t stop an ad, except in rare circumstances

Using Sound„ ... users always expect to hear alarms that they have set.“

• Ring/Silent Switch (avoid sound if it is not explicity set)

• Volume Buttons (the user always decided the loudness)

• Headset and Headphones (plug in headsets means sound has to be set privately)

• Wireless audio (disconnection = pause, connection = no pause)

• Defining the Audio Behavior is essential task

Starting„iPhone Application should start instantly so users can begin using them without delay“

• Specify appropriate status bar styles

• Display a launch image

• Avoid displaying an About window, splash screen or another tpye of startup experiences

• Launch in portrait orientation

Stopping„iphone Applications should never quit programmatically“

• Be prepared to receive an exit or terminate notification at any time.

• Save the current state when stopping

• Avoid alerts

• User has to decide if continuing you application or pressing the Home Button

Settings and Configuration„It‘s best when iPhone application do not aks users to specify any settings at all“

• Focus your solutions on the needs of 80 percent of users

• Get as much information as possible from other sources

• If you must ask for setup-information, prompt users to enter within your application

• Offer configuration options in the main user interface or on the back of a screen

....„Don‘t provide a button for a built-in action, because users will wonder why there are two ways to do the same thing in your application“

• Support Copy and Paste

• Support Undo and Redo

• Enabling Push Notifications (delivery is not guaranteed)

• Providing Search and Displaying Search Results

• Using the User‘s Location

Brief Tour of the Application User Interface

http://www.flickr.com/photos/ari/4314027331

Main parts of application screen„Every application, regardless of type, has an application window“

• Status Bar

• Navigation Bar

• Tab Bar

• Toolbar

Users are accustomed to the look and behavior of standard views and controls

http://www.flickr.com/photos/r_catalano/4180965353

Status Bar„People expect to see the current battery charge of their device; hiding this information [...] is not an ideal user experience“

• hiding status bar in case of immersive application (carefully decision)

• important bar (cell signal strength, network, battery)

• three possible colors

Navigation Bar„ ... appears at the upper edge of an application screen, just below the status bar.“

• enable navigation among different views in an application

• provide title and controls that manage the items in a view

Tool Bar„ ... performs actions related to objects in the current view.“

• constrain the number of items (44*44 pixels)

• use the predefined buttons

• colors blue and black

Tab Bars„ If you application provides different perspectives on the same set of data, ... .“

• icons and text, all equal in width and black background

• tab does not change its opacity or height, regardless of orientattion

• more than five tabs, iPhone OS add a „More“ tab

• badging a Tab is possible to communicate in a noninstrutive way

Alerts, Action Sheets, Modal Views„ ... appear when something requires the user‘s attention ... “

Alerts„ ... give users criticial information in a highly visible way. “

• minize the number of alerts

• ask for confirmation

• single / double button alert

• provide feedback when user select a list item

• display content immediately

• plain / group style

• different table-view elements

Text View

„ ... is a region that displays multiple lines of text ....“

• Activity Indicators

• Date and Time Pickers

• Disclosure Buttons

• Info Buttons

• Labels

• Page Indicators

• Pickers

• Progress Views

• Rounded Rectangle Buttons

• Search Bars

• Segmented Controls

• only available in iPad

• use to display persistent information in the left pane and related details in the right pane

• both panes can contain table, image, map, text, web or custom views as well as navigation bars, tool bars or tab bars

• avoid creating a right pane that is narrower than the left pane (left pane is fixed to 320 points in all orientations)

• indicate the current selection in the left pane

Sytem Provided Buttons„ ... promote a consistent user experience and make your job easier.“

Creating Custom Iconsand Images

http://www.flickr.com/photos/conorpendergrast/2634918994

Application Icons„This is a place where branding and strong visual design should come together into a compact, instantly instantly recognizable, attractive package.“

• rounded corners, drop shadow, reflective shine automatically added

• measures 57*57 pixel (114*114 for high resolution)

• small icon for spotlight search (29*29; 58*58 high resolution)

Launch Images„To enhance the user‘s experience at application launch ... .“
