HCI101 - Introduction to Human Computer Interaction (Midterm Reviewer)

Do not change something unless it really needs changing.

Three types of consistency

Interface error messaging such as "We're sorry, but that page cannot be found."

Requirements Specification does not involve eliciting information about the domain

The mental workload is minimized by splitting this data into individual parts or different pages.

Also known as Split Testing, technique for comparing different versions of a template or interface

The third step or process in the Waterfall Model is Detailed Design

If the product is not usable, calls to customer support can be enormous

Indicates limitations of user action

Design guidelines are specific and usually context dependent

ACM stands for

The ultimate test of usability based on measurement of user experience.

Movement of information from the environment into the human mind and back into the world.

Including changes in substance and circumstances.

Feedback should support three important factors of user activity:

Created by the designer as a high-level plan for how the product will work and fit together.

Avoid implementing features users do not want and creating features that are annoying or inefficient

The term HCI was adopted in

Involves designing a user interface to possess human-like qualities

High-level and context-free design goals based on theories of human computer interaction.

Seven (7) deep metaphors

Involves eliciting information from the customer about the work environment, or domain

Refers to how good a system at doing what it is supposed to do.

Are the tasks assigned to users, such as sending emails to customers.

A simplified depiction of a real-world phenomenon.

Refers to a user’s underlying expectations about how something should work.

HCI principles should be consulted for: Safety, ______, Efficiency

Correspondence between the system's representation and real-world phenomenon in appearance, meaning, and operation.

All work on the system is not considered under the category of maintenance

Two main models of the software life cycle

It refers how easy a system is to learn to use

At physical level, HCI concerns the selection of the most appropriate input devices and output devices

An interaction style in which objects are represented and manipulated in a manner analogous to the real world.

Element of UCD where users should be able to see from the beginning what they can do with the product, what it is about

The use of familiar terms and associations to represent a new concept.

Feedback should help develop accurate mental models.

Generally regarded as ensuring that interactive products are easy to learn, effective to use, and enjoyable...

Specific and usually context dependent rules for designers to follow in order to achieve the principles.

Usability Goals

The same appearance, meaning and operation holds true for all the user’s interactions within the same application.

It refers to the extent to which the system provides the right kind of functionality so that user can do what they need.

The sense of mastery, vulnerability, and well-being

Text should be easy to read

It involves protecting the users from dangerous conditions and undesirable situations.

Relies on the user's familiarity with another concept as well as affordances

Discipline for understanding the software design process, or life cycle.

Useful for examining and comparing the usability of multiple conceptual designs.

A collection of processes which focus on putting users at the center of product design and development.

Verification is designing the right product

In designing a user interface, this method takes into account the human brain's ability and sensory experience.

The same appearance, meaning and operation holds true for the user’s interactions across applications

The aspects of an object that the user perceives as indicating how to use the object.

GOMS stands for

Efficiency is a very general goal and refers to how good a system at doing what it is supposed to do.

Different types of prototypes

Most well-known metaphor in HCI

Designing the PRODUCT RIGHT

Discipline concerned with the design, evaluation & implementation of interactive computer system for human use...

Example of Affordances is zoom slider

·The use of familiar terms and associations to represent a new concept is called Affordances.
