Study Notes

Interaction Design ISB36403: Designing for Different Needs

The course focuses on designing user interfaces for different user needs and levels of experience
Personas and scenarios help in focusing design efforts on real users' goals, behaviors, needs, and mental models
Consistent patterns in user needs inform product design
The lecture covers strategies for serving well-known user needs, including learnability, help, customizability, localization, globalization, and accessibility.

1. Learnability and Help

Designing interfaces should consider users with varying skill levels
The following concepts simplify learning: command modalities and working sets
Online help is a backup option if other methods are insufficient

1. Command Modalities

User interfaces allow users to enter data and issue commands
Basic data entry methods are straightforward
- Dictating to speech recognition
- Typing
- Drawing
- Clicking and dragging
- Selecting from menus
Commands that activate functions are more complex for users to learn
Distinct techniques (command modalities) are crucial for instructing applications
- Direct manipulation
- Drop-down and pop-up menus
- Tool bars
- Keyboard accelerators
- Gestures or controls
Multiple command modalities are useful for critical functions
Redundancy lets users with diverse skills use the application effectively.
Mobile apps frequently have fewer interface elements to search through, which makes finding features faster
Pedagogical commands educate users by directly showing the process
Immediate commands instantly affect the data without any intermediate steps.
Invisible commands can be performed without visual indications, often through keyboard accelerators or gestures,

Information in the world vs information in the head

Information in the world refers to situations in which insufficient interface information is available
Information in your head refers to knowledge acquired through learning
Choosing between these two involves factors, like the speed, bulkiness, and dependency

Memorization vectors

Providing specific methods for remembering commands is crucial
This can involve documentation, online help, or directly integrating commands into the interface
Windows applications typically use mnemonics and accelerators
Mac applications often use accelerators and toolbar icon mappings
Memorization connections can usually be understood quickly.

Working sets

Users learn through repetition
A working set consists of frequently used interface features
Data entry (e.g., formulas, formatting, printing), drawing graphs, and linking spreadsheets are examples
Usage analytics can be used to determine the minimal working set
Working set commands should be quick and easy to use

Contextual help and assistive interfaces

Help should be provided in the context of use
Examples of assistive interfaces include:
Guided tours and overlays
Galleries and templates
Input and content area hints
Pros and Cons of Wizards
Tooltips and ToolTip overlays

Guided Tours and Overlays

Guided tours use sequential screens and images to introduce features and behaviors of the app
Launching automatically is a common method
Overlays are transparent sheets showing arrows for directions or descriptions
Best suited for simple apps

Galleries and Templates

Pre-built templates are part of the interface
These allow faster development by referencing previously used tools or items

Input and content area hints

Provide contextual details in the input area

Pros and Cons of Wizards

Wizards, developed by Microsoft, quickly gained popularity for helping with new tasks
They lead users step by step to complete actions or functions

Concise, visual explanations of actions or interface functions

Traditional Online Help

Complex applications need comprehensive reference documentation, because many users access general internet search engines for solutions.
These documents provide information like overview descriptions, full-text search, indexing, and in-app user guides

2. Customizability

Designers often decide whether products should be user-customizable
Examples of customization include personalization, configuration, and idiosyncratic modal behavior

3. Localization & Globalization

Localization involves translating applications for specific languages and cultures.
Globalization aims to make apps universal for various languages and countries

4. Accessibility

The World Health Organization estimates accessibility needs of 750 million people worldwide
Interactions should be easy for all types of users, including those with disabilities
Accessibility personas help in understanding user needs and creating better interfaces for diversity
Accessibility guidelines, such as leveraging OS tools, avoiding overriding user settings, supporting keyboard access, and tailoring display options, should be followed to improve the UX
