HCI module 1 Flashcards
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
Central to interaction design and operations through specific computer system criteria, including efficiency, utility, and learning/retention.
Usability
Focuses on creating system that are satisfying, enjoyable, entertaining, helpful, motivating, aesthetically pleasing, creativity, supportive, rewarding, fun and emotionally fulfilling.
User Experience
Principles of HCI
Know your user
Reduce memory load
Prevent errors/ rehersal of action
Strive for consistency
Understand the task
Remind users and refresh their memory
Naturalness
Refers to trait that is reflective of various operations in our everyday life
Naturalness
a property (additional cues) that appeals to our innate perception and cognition, thus making it so intuitive that the interface would require almost no learning.
Affordance
Kids, elders, athletes, students, parents, etc.
User type
Smartphones, e-book, desktops, etc.
Platform/ System setup
Smartphones, e-book, desktops, etc.
Platform
NASA, Korea University, etc.
Vendors/ Organization
voice/aural , gesture, etc.
Interface Style/ Modality/ technology
Office, outdoor, road/ street, home, automobile, subway, etc.
Task operational context
Game, Media/ Information, Electronic commerce, Design/ Editing, Social Network Service
Application
Display layout, User Experience, Soliciting input, Information structure/ navigation, Design process and practices, General Aesthetics
General HCI design
This principle simply states that the interaction and interface should cater to the needs and capabilities of the target user of the system in design
Know your user
Designing interaction with as little memory load as possible is principle that also has theoretical basis.
Reduce memory load
One effective technique is to present or solicit only the relevant information/action as required at given time
Prevent errors/ Reversal of action
In the long term, one way to unburden the memory load is to keep consistency
Strive for consistency
Another almost-commonsensical principle is to base HCI design on the understanding on the task.
Understand the task
Any significant task will involve the use of memory, so another good strategy is to employ interfaces that give continuous reminders of important information and thereby refresh the user’s memory.
Remind users and refresh their memory
