HCI module 1

Question 1

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

Answer 1

Human Computer Interaction

Question 2

Central to interaction design and operations through specific computer system criteria, including efficiency, utility, and learning/retention.

Answer 2

Usability

Question 3

Focuses on creating system that are satisfying, enjoyable, entertaining, helpful, motivating, aesthetically pleasing, creativity, supportive, rewarding, fun and emotionally fulfilling.

Answer 3

User Experience

Question 4

Principles of HCI

Answer 4

Know your user
Reduce memory load
Prevent errors/ rehersal of action
Strive for consistency
Understand the task
Remind users and refresh their memory
Naturalness

Question 5

Refers to trait that is reflective of various operations in our everyday life

Answer 5

Naturalness

Question 6

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.

Answer 6

Affordance

Question 7

Kids, elders, athletes, students, parents, etc.

Answer 7

User type

Question 8

Smartphones, e-book, desktops, etc.

Answer 8

Platform

Question 9

Question 10

voice/aural , gesture, etc.

Answer 10

Question 11

Office, outdoor, road/ street, home, automobile, subway, etc.

Answer 11

Task operational context

Question 12

Answer 12

Application

Question 13

Display layout, User Experience, Soliciting input, Information structure/ navigation, Design process and practices, General Aesthetics

Answer 13

General HCI design

Question 14

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

Answer 14

Know your user

Question 15

Designing interaction with as little memory load as possible is principle that also has theoretical basis.

Answer 15

Reduce memory load

Question 16

One effective technique is to present or solicit only the relevant information/action as required at given time

Answer 16

Prevent errors/ Reversal of action

Question 17

In the long term, one way to unburden the memory load is to keep consistency

Answer 17

Strive for consistency

Question 18

Another almost-commonsensical principle is to base HCI design on the understanding on the task.

Answer 18

Understand the task

Question 19

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.

Answer 19

Remind users and refresh their memory
