Week 10 Physical Design: Getting Concrete

Design is about making choices and decisions.
It is where we balance out between Environmental, User, Data, Usability requirement and Functional requirement.

Guideline for us when designing for a different culture like for international design:

• Be careful about using images that depict hand gestures or people.
• Use generic icon.
• Choose colour that are not associated with national flags or political movements.
• Ensure that the product supports different calenders, date formats and time formats.
• Ensure that the product supports different formats, currencies, weights and measurement system.
• Ensure that the product supports international paper sizes, envelope sizes and address format.
• Avoid integrating text in graphics as they cannot be translated easily.
• Allow for text expansion when translated from English.

Using Scenarios in Design
4 roles for scenarios:

1. A basis for overall design.
2. For technical implementation.
3. As a means of cooperation within design teams.
4. As a means of cooperation across professional boundaries.

Generating prototypes in design

Generating storyboards from scenarios:

• Steps in the travel organizer scenario
  
  • Focus solely on the screen
  • Focus solely in the environment
• Generating storyboards from use cases
• Generating card-based prototype from use cases

Using prototypes in design

Prototyping physical design:

• Expand the cards to generate a more detailed software or paper-based pro type.
• Tool support:To support sketching tools, environments to support icon and menu design

Generate Card-based Prototype from Use Cases

• Paper prototype is a fast and easy way to change and re-design your interface.
• Four important people are involved in Paper Prototyping which are:
  
  1. user
  2. person who acts as a computer
  3. someone who becomes the facilitator
  4. observer

Other ways of prototyping: animatics and rapid sketch prototyping which uses a program to make it interactive.
