The Task-Centered Design Process

• figure out who's going to use the system to do
  what
• choose representative tasks for task-centered
  design
• Plagiarize
• rough out a design
• think about it
• create a mock-up or prototype

• test it with users
• iterate
• build it
• track it
• change it

Two guidelines for design
1. Provide a good conceptual model allows user
to predict the effects of our actions problem des
igners conceptual model communicated to user
through system image appearance, written
instructions, system behavior through
interaction, transfer, idioms and stereotypesif
system image does not make model clear and
consistent, user will develop wrong conceptual
model

Two guidelines for design (continued)

• 2. Make things visible
• relations between users intentions, required
  actions, and results are
• sensible
• non arbitrary
• Meaningful
• visible affordances, mappings, and
  constraintsuse visible cultural idiomsreminds
  person of what can be done and how to do it

Prototyping and construction

• What is a prototype?
• Why prototype?
• Different kinds of prototyping low
  fidelity high fidelity
• Compromises in prototyping vertical horizontal
• Construction

What is a prototype?
In other design fields a prototype is a
small-scale model
A miniature carA miniature building or town

Why prototype?

• Evaluation and feedback are central to
  interaction design

• You can test out ideas for yourself

• It encourages reflection very important aspect
  of design

• Team members can communicate effectively

• Stakeholders can see, hold, interact with a
  prototype more easily than a document or a drawing

• Prototypes answer questions, and support
  designers in choosing between alternatives

What to prototype?

• Technical issues
• Work flow, task design
• Screen layouts and information display
• Difficult, controversial, critical areas

Product prototype company gives innovators,
product designers and industrial engineers the
ability to hold and test as many product
prototypes as they require. you will not have to
keep rectifying the final product but you can get
a perfect and flawless final product. You can
visit our website for any requirement.
