C1 Flashcards
Why HCI?
Computers and devices should be design with users in mind
System Designers should know users’ task and convert it into executable system
Mistaken view for its not easy to design consistent and robust systems.
Designer - People - User
Cannot be plugged in at the last minute
Developed integrally
Not just a pretty face
Support tasks and forgive careless mistakes
Interface
EC Directive 90/270/EEC rules when designing, selecting, commissioning or modifying software:
Suitable for the task
Easy to use and where appropriate adaptable to the user’s knowledge and appearance
Provides feedback on performance
Displays information in a format and at a pace that is adapted to the user
Conforms the principles of software ergonomics
HCI started in the
Early 1980s
HCI on its early years wasn’t
wasn’t particularly important
HCI was also knwn as
Ergonomics (UK)
Human Factors (NA)
Man-Machine Interaction
HCI disciplines are concerned with
user’s performance
Design + Implementation + Evaluation == Interactive Systems
In the context of
User’s task and work
Original and abiding technical focus of HCI was and is
USABILITY
Three parts of HCI
User - who is trying to get the job done using tech
Computer - any tech
Interaction - communication between the both
Who involved in HCI?
Psychology and Cognitive Science Ergonomics Sociology Computer Science and Engineering Business Graphic Design Technical Writing And many more -- involve the users
What is the underlying principle of HCI?
People use computers to accomplish work
4 major concerns of HCI
People
Computer
Task
Usability (system must support the user’s task)
What real tasks are>
Understanding of tasks at the moment
Study the user’s current task
What are the three use words?
Useful - accomplish what is required
Usable - do it easily and naturally without danger of error, etc.
Used - make people want to use it
Another important concerns of HCI?
Motivation
Enjoyment
Experience
Goal of interaction design is to
Reduce the negative aspects of the user epxerience while enhancing the positive ones
developing interactive products that are usable is being talked about
Interaction Design
It is important to take into account about HCI to
where it is going to be used
who is going to use it
Factors to consider on HCI
Who is going to be using them
How they are going to be used
Where they are going to be used
Understand the kind of activities people are doing when interacting with the products
Thinking about the TYPES of INTERFACES and INTERACTIVE devices that are available
multitouch displays speech-based systems handheld devices large interactive displays etc
Think of ways how users can interact with a system
use of menus commands forms icons gestures etc.
Think of more innovative artifacts using novel materials
e-textiles
wearables
