Maximize compatibility with current and future user tools

Explains the human’s capability and model of conscious processing of high-level information

Stores momentarily and short-term information or long-term knowledge.

Elucidates how raw external stimulation signals are accepted by our five senses,

Refers to the amount of sound energy and is synonymous with the more familiar term, volume.

Is define to be the modality that takes advantage of touch by applying forces, vibrations, or motions to the user.

The lightest amount of pressure humans can sense is said to be about 1000 N/m2

Providing users with alternative wats to interact gives people more choices

Senses external information

Interprets and extract basic meanings of the external information

_____ modality is by far the most important information medium

The amount of light energy emitted by the object

Human response to different wavelengths of light, namely for those corresponding to red, green, blue, and their mixtures.

This is the angle subtended by the visible area by the human user in the horizontal or vertical direction.

A display system is typically composed of an array of small rectangular areas called pixels

Rapid movement such as vibration is mostly sensed by the Pacinian corpuscle, which is known to have signal response range of 100 300Hz

Refers to the time differences among sound waves that emanate from the same source

Different modalities can assume different roles and act in a complementary fashion to achieve specific interaction objectives.

A model of human movement that predicts the time required to

rapidly move to a target area as a function of the distance to and the size of the

target.

Three important parts of HCI

1.For a product to be successful, it must be:

What are the three parts of the HCI?

Perhaps the most prevalent form of input is made by the movements of our arms,

hands, and fingers for keyboard and mouse input.

Different modality input methods or feedback can be used to ensure a reliable achievement of the interaction objective.

Different modalities can assume different roles and act in a complementary fashion to achieve specific interaction objectives.

This is the number of pixels in the horizontal and vertical direction for a fixed area.

The human eye contains two types of cells that react to light intensities in different ways

Formulates and revise a “plan” then decides to what to do based on various knowledge in the memory, and finally acts it out by commanding the motor system

The display layout should be such that is is organized according to the information content

When designing a system you make the text readable and understandable

When designing a system you make all functionality unavailable from a keyboard

When designing a system you must not provide text alternatives for non-text content

When designing a system you must maximize compatibility with current and future user tools

Cognitive Science explains the human’s capability and model of conscious processing of high-level information

So far, the aural modality has been explained only in the context of passive feedback.

Touch and Tactile are the same

Ergonomics, elucidates how raw external stimulation signals are accepted by our five senses, are processed up to the pre-attentive level, and are later acted upon in the outer world through motor organs.

Sensation interprets and extract basic meanings of the external information

Perception senses external information
