Study Notes

Interaction Design ISB36403

Course focuses on design for desktop, mobile, and web, specifically Part 3: Designing for Mobile and Other Devices.

Outline

Anatomy of a Mobile App
- Mobile Navigation, Content, and Control Idioms
- Multi-Touch Gestures
- Inter-App Integration
- Other Devices

Introduction

June 2007's iPhone revolutionized mobile UX.
iPhone introduced large, high-resolution multi-touchscreens, with on-screen controls sized for finger use.
Introduced a set of intuitive, easily-learned gestural idioms.
Leveraged sensors for contextual information (orientation, location, light, movement), improving app intelligence.
iPad followed a similar design approach.

Anatomy of a Mobile App

Mobile apps have transient interactions, brief and intermittent, focusing on specific tasks.
Limited screen space necessitates zooming, increasing complexity and potential confusion.

Mobile Form Factors

Handhelds:
- Small devices (iPod Touch-like)
- Tall and narrow screens (4-6 inches)
- Typically 16:9 aspect ratio, portrait orientation
Tablets:
- Larger (9-10 inch) screen size
- 4:3 or 16:9 aspect ratio
- Often landscape orientation, sometimes portrait
Mini-tablets:
- Smaller than tablets (7-8 inches)
- Similar aspect ratios to handheld and tablets

Handheld Format Apps

Stacks: Common layout pattern, arranging elements vertically.
Screen carousels: Horizontal scrolling displays related content in full-screen views.
Orientation and layout: Apps should dynamically adjust for portrait and landscape modes.

Tablet Format Apps

Stacks and index panes: Vertical stacking of primary content with additional panes for extra functionality.
Pop-up control panels: Non-overlaying panels to configure tools.
Orientation-based layout: Apps need to respond dynamically to orientation changes.

Mobile vs. Desktop-Like Layout

High-resolution tablet screens match laptop/desktop displays.
Treating tablet apps as shrunken desktop versions may not be effective.
Certain apps, like media production software, can benefit from a complex desktop-like layout.

Mobile vs. Desktop-Like Layout: Design Principles for Complex Layouts

Organize toolbars, control panels, and menus with appropriate spacing for finger interaction.
Offer alternative methods for drag-and-drop to avoid accidental drops on touchscreens.
Clearly label and connect pop-up menus back to their associated elements.
Design a linear workflow to keep user tasks clear and easy to accomplish.
Optimize for a single orientation and stick to it, rather than supporting both.

Hardware-Like Control Layout

Interfaces resembling hardware (e.g., rotary controls, drag gestures) appeal to users familiar with those types of interactions.
Avoid limiting UI by adhering too strictly to hardware metaphors.

Mini-Tablet Format Apps

Limited space reduces options for prominent controls.
Consider vertically oriented toolbars instead of horizontal or top-bottom controls.
Lists and single-column layouts often appear out of proportion on mini-tablets.

Many mobile controls are similar to desktop/web apps.
Unique form factors and multi-touch inputs lead to a new set of design idioms suited for mobile apps.

Browse Controls

Mobile apps are designed for browsing content.
Popular browsing patterns include lists, grids, content carousels, swimlanes, and cards.

Lists

Navigating lists in mobile apps often works by drilling down hierarchy levels.
Lists work with tab bars or provide infinite scrolling.

Grids

Used for visually organizing content (e.g., app icons, thumbnails).
Galleries often represent grid-based content.
Many apps use infinite scrolling to manage grid-based data.
Apple's Photos app uses grids.

Content Carousels

Swiping horizontally to navigate full-screen layouts with different data.
Carousels may be content or 3D.

Swimlanes

A mix of carousels and grids, navigating different full-screen layouts.

Cards

Combining text and visual media in clearly formatted chunks.
Commonly used for displaying information in a vertically scrolling list.

Bars enable navigation between app features and content.
Commonly used control types include tab bars, tab carousels, navigation bars, action bars, and tool bars.
Vertical toolbars, desktop-like menus, and embedded toolbars are also viable.
Carousels let users easily choose a tool or setting.

Drawers

Vertical lists providing access.
Use minimal screen space by hiding elements.
Tapping a drawer swaps content and closes it.
Can be used as secondary action, replacing the tab bar, or as an item-level drawer.
Double drawers are possible and may help to declutter screen real estate.

Tap-to-reveal and Direct Manipulation Controls

Users tap to reveal associated controls.
Controls are often positioned directly within the main display for immediate interaction.

Searching, Sorting, and Filtering

Mobile apps use voice search, auto-complete, tap-ahead, and recent/frequent search history to help with search queries.
Sorting and filtering common functions to help refine results.

Welcome and Help Screens

Limited screen real estate requires new techniques.
Multi-touch interactions emphasize gestures.
Replacing hover controls require alternative help mechanisms.
Often feature guided tours, overlays, and tooltips.

Other Devices

Design involves thinking of hardware as an essential design feature.
The hardware/software integration should balance navigation and display density.
Designers should incorporate context into the design.
Designers should keep the design scope limited to avoid exceeding capabilities.

Q&A, Next Session

A session to answer questions and prepare for the next session of the course.
The course continues with topics about the design of desktop, mobile, and web applications.
