Question list

It is a cross-disciplinary area that deals with the theory, design, implementation, and evaluation of ways human use and interact with computing devices.

Human-Computer Interaction

It is the interactive design and operations through specific computer system criteria which includes correctness, efficiency, safety, utility, learning, and retention.

High usability

focuses on creating systems that enhance the overall involvement of a person, which must include a satisfying, enjoyable, entertaining, helpful, motivating, aesthetically pleasing, and fun experience to the user.

User experience

refers to an abstract model by which humans interact with the computing device to complete a given task.

Interaction

On the other hand, refers to the boundary wherein two (2) independent systems meet and act on or communicate with each other.

Interface

Commonly known as “user-centered design,” this principle serves as the primary principle of HCI.

Know the User

What is NOT an example of know the user

Understand the Task

Humans are more efficient in performing tasks that require light memory load, either for long term or short term memory

Reduce Memory Load

A significant task involves the use of memory. Another strategy is to employ interfaces that provide constant reminders about important information or actions to be performed and thus refresh the user’s memory.

Remind Users

In performing any given task, it is important to complete the task without any error.

Prevent Errors/Reversal of Action

This principle refers to the reflection of various actions and processes in human’s daily life.

Natural Interaction and Interface

These are a set of information intended to advise people on how something should be done or what something should be.

Guidelines

are a set of recommended information used to direct HCI design and development. These guidelines can be divided into criteria and category.

HCI Guidelines

Display layout, information structure, soliciting input, output visualization, design process and practice, user experience, general aesthetic

General HCI Design

Kids, visually challenged, baby boomers, students, athletes, elders

User Type

Smartphones, desktop, kiosk, embedded OS, cloud-based, MP3 player, e-book

Platform/System Setup

NASA, iOS, Android, Windows XP

Vendor/Organization

Voice, gesture, multitouch, multimodal, menu driven, GUI/widgets

Interface Style/ Modality

Location, time, noise/lighting, bodily constraints

Task/Operational Context

Game, media, e-commerce, design/editing, social network service

Applications

Display layout, or page layout, is one of the focus of design guidelines.

Visual Display Layout (General HCI Design)

Crafty designs for taking user input, such as raw information and system commands, can improve the overall performance, especially time and accuracy, for high interactive systems

Taking User Input (General HCI Design)

is an interface through which a user interacts with electronic devices such as computers, mobile devices, and other appliances

Graphical User Interface (GUI)

This set of guidelines covers a wide range of recommendations for making Web content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, and limited movement

User with Disability (User Type)

Information and user interface components must be presentable in ways users can perceive.

Perceivable

User interface components and navigation must be operable.

Operable

Information and the operation of user interface must be understandable.

Understandable

Content must be robust enough that it can be interpreted by a wide variety of user agents, including assistive technologies.

Robust

Usability and other user experience of mobile devices and applications have become more important

Mobile Device (Platform Type)

senses external information through aural, haptic, or visual modality

Sensation

interprets and extracts basic meanings of the external information

Perception

stores short-term or long-term information about external procedures, rules, relations, schemas, and the likes

Memory

formulates and revises a solution or plan, decides based on various information in the memory, and finally acts it out by commanding the motor system.

Decision/Executor

is the difference between the intentions of the users and what the system allows them to do or how well the system supports those actions.

Gulf of execution

is the degree to which the system provides representations that can be directly perceived and interpreted in terms of user expectations and intentions.

Gulf of evaluation

GOMS stands for...?

goals, operators, methods, and selection rules.

is the most important information medium today.

Visual modality

the observable area a person can see through the eyes

Field of View

the the distance from the eyes to the surface of the display area a person can see through the eyes

Viewing Distance

the area subtended by the display from a particular viewing distance

Display field of View

small rectangular areas which compose a display system

Pixel

the number of pixels in the horizontal and vertical directions for a fixed area

Display Resolution

the resolution perceived by the eye from a fixed distance

Visual acuity

the amount of light emitted by an object or as perceived by the human eye

Brightness

the human response to different wavelengths of light, namely for those corresponding to red, green, blue, and their mixture

Color

the relative difference in brightness or color between two (2) objects

Contrast

is the next most common mode of information feedback.

Aurial Modality

Also known as volume, this refers to the amount of sound energy.

Intensity

This is the energy transmitted in the form of waves with different frequencies.

Sound

This refers to the time differences among sound waves that originate from the same source.

Pulse

This is the ability of a machine or a program to identify words and phrases in spoken language and convert them to a machine-readable format.

Speech Recognition

is considered as a natural way of interacting with computers. The term “haptic” pertains to the technology that uses touch to control and interact with computers.

Haptic Modality

has been advancing in the industry with the ubiquity of multimedia devices.

Multimodal interaction

Different modalities can adopt different roles and act in a complementary manner to accomplish specific interaction objectives.

Complementary

Different input method or feedback can be used to guarantee a definitive accomplishment of the interaction objectives

Redundant

Multimodal interaction provides users with alternative ways to interact gives users more options.

Alternative

is also known as motor capabilities.

Human Body ergonomics

is another method of initiating and performing voluntary movement. Humans exhibit different motor control practices with different devices.
