HCI Flashcards
It is a multidisciplinary field that involves different skill set depending on the objective they’re trying to attain.
Interaction Design
Interaction design’s main concern
Product to be usable
Refers to how a product behaves and is used by people in the real world
User Experience
Who said ““Every product that is used by someone has a user experience: newspapers, ketchup bottles, reclining armchairs, cardigan sweaters.”
Jesse Garret
UX sometimes refers by designers as UXD, where D meant to encourage
Design Thinking
Important aspects of the user experience are the following:
usability
functionality
aesthetics
content
look and feel
emotional appeal
the social resouces that develop and are maintained through social networks and social networks, shared values,goals, and norms
Social Capital
i.e. age, ethnicity, race, disability, family status occupation and education.
Cultural Identity
It is how simple, practical, and obvious it is for the user to achieve their goals.
Pragmatic
It is a concept that has only been commonly used since the early 1980s, but it has origins in more developed disciplines.
Human Computer Interaction (HCI)
It is how evocative and stimulating the interactions is to them.
Hedonic
It is how simple, practical, and obvious it is for the user to achieve their goals
Pragmatic
Ergonomics Research Society was founded in
1949
The researchers of Ergonomics Research Society were called
ergonomists
The Human Factors, however were concerned both the
Physical and Cognitive issues
Human Computer Interaction was originally called
Man-Machine Interaction
It played a big role in the development of HCI
Information science and technology
It should be defined as someone who is trying to get the job done using any kinds of technology
User
This could be any technologies which ranges from the a desktop computer systems to a large-scale computer systems, a process control system, or even an embedded system
Computer
Any communication, direct or indirect between a user and a computer
Interaction
They must understand how to think in terms of the end user’s challenge and how to translate that understanding into a working system.
System Designers
Involved knowledge about perception, cognitive, and problem –solving skills;
Psychology and cognitive science
Involved in Physical capabilities of the user
Ergonomics
Involved in understanding the wider context of the interaction
Sociology
Involved in building the necessary technology
Computer science and engineering
Involved for marketing
Business
Involved in more effective interface presentation
Graphic Design
Involved in producing manuals
Technical writing
It is known as an interdisciplinary topic, people tend to take a hard stand on one side or the other in practice.
HCI
In line with this, the three major concerns involved are the
(1) people, (2) computer, and the (3) tasks that are performed
Fourth Concern
System should support the user’s task in a usable manner
It should accomplish what is required, i.e. watch movie, format a document, ring the alarm;
Useful
Do it easily and naturally, without danger of error, etc.
Usable
Make people want to use it, be attractive, engaging, fun, etc.
Used
Learned from the past on how to achieve good results, avoiding the bad ones
Reuse lessons
It is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers.
Human-computer interaction
This __________________ allows us to reuse related concepts in similar situations, in much the same way that architects produce a bridge, knowing that it will stand, since it was based upon tried and tested principles.
Scientific Rationalization
True or False: The important thing is that the user is interacting with the computer in order to accomplish something
True
There are five major senses:
sight, hearing, touch, taste and smell
The three senses that are the most important to HCI
Sight
Hearing
Touch
It is a highly complex activity with a range of physical and perceptual limitations, yet it is the primary source of information for the average person.
Human Vision
Stages of Visual Perception
-Physical reception of the stimulus
-Processing and Interpretation of that stimulus
“Design is not just what it looks like and feels like. Design is how it works.”
Steve Jobs
It involves examining and defining the interactions
Interaction Design (IxD)
“the goal of creating products that enable
the user to achieve their objective(s) in the best way possible.”
The Interaction Design Foundation
It strives to create more meaningful relationships between people and the products and services that they use.
Interaction Design
What happens on the screen
User Interface (UI)
What happens in front of the screen
User Experience (UX)
It makes a product useful.
Good Design
It is one which is not easy to understand, distracting, difficult to use and short lived
Bad Design
It involves the study, planning, and design of the interaction between
people (users) and computers.
Human Computer Interaction
Interaction Design is the practice of:
Understanding users’ needs and goals
Designing tools for users to achieve those goals.
What is the difference between interaction design and HCI?
IxD is much broader than HCI, because it includes all means of technology,
system, and products, while HCI concerns interactive computing
system.
When you’re designing for learnability
You have to be aware of how people actually learn
It is about creating effective user interfaces (UIs)
Usability
The conventional model for human memory has two components:
Working memory and Long-term memory
the capacity of working memory is ______ chunks
7+-2
The process of putting information and procedures into long-term memory
Learning
It seeks to make connections with existing chunks
Elaborative Rehearsal
It is where you do your conscious thinking
Working Memory
Distractions can easily destroy ________
Working Memory
It is repeating the items to yourself
Maintenance Rehearsal
It contains the mass of our memories. Its capacity is huge, and it exhibits little decay.
Long-term Memory
It is probably the least understood part of human cognition
Long-term Memory
It lies behind the power of mnemonic techniques like associating things you need to remember with familiar places, like rooms in your childhood home
Elaborative Rehearsal
The elements of perception and memory are called
Chunks
Represents the activation of past experience.
Chunk
It is remembering something with no help from the outside world
Recall
It is remembering with the help of a visible cue
Recognition
Three major kinds of user interface styles for desktop computing
Computer with a screen, keyboard, and mouse
It is rarely the first choice of a user interface designer nowadays, they still have their place – often as an advanced feature embedded inside another interaction style.
Command Language
It presents a series of menus or forms to the user
menu/form interface
