Any effort to design an effective interface for human-computer interaction (HCI) requires two basic elements: an understanding of:
(a) Computer factors (software/hardware) and
(b) human behavior.
Human Information Processing
Human Body Processing
As the main underlying theory for HCI, human factors can largely be divided into 2:
cognitive science
neurology
Physics
ergonomics
aerodynamic
Task/interaction modelling:
Understand and predict how humans might react mentally to various information-presentation and input-solicitation methods as a basis for interface selection.
True
False
Task/interaction modeling: Formulate the steps for how humans might interact to solve and carry out a given task/problem and derive the interaction model.
True
False
Prediction, assessment, and evaluation of interactive behavior:
Understand and predict how humans might react mentally to various information-presentation and input-solicitation methods as a basis for interface selection.
True
False
Sensation, which senses external information
(a)
(a) which interprets and extracts basic meanings of the external information.
(a) which stores momentary and short-term information or long-term knowledge
(a) which formulates and revises a “plan,” then decides what to do based on the various knowledge in the memory, and finally acts it out by commanding the motor system (for example. to click the mouse left button).
to some degree, predict how humans will react and perform in response to a particular human interface design.
We can consider two aspects of human performance:
one that is _______ and the other ______.
cognitive
memory
ergonomic

What is GOMS
(a)
The original GOMS model was developed mainly for the desktop computing environment, with performance figures for mouse clicks, keyboard input, hand movement, and mental operators.
True
False
(a) modality is by far the most important information medium. Over 40% of the human brain is said to be involved with the processing of visual information.
Field of view (FOV):
This is the angle subtended by the visible area by the human user in the horizontal or vertical direction.
True
False
Viewing distance: This is the perpendicular distance to the surface of the display.
True
False
Display field of view: This is the angle subtended by the display area from a particular viewing distance
True
False
Pixel: A display system is typically composed of an array of small rectangular areas called pixels.
True
False
Display resolution: This is the number of inches in the horizontal and vertical directions for a fixed area.

False
Visual acuity: In effect, this is the resolution perceivable by the human eye from a fixed distance.
True
False
The human eye contains two types of cells that react to light intensities in different ways.
The cones, which are responsible for color and detail recognition, the rods are distributed mainly in the periphery of the retina and are responsible for motion detection and less detailed peripheral vision.

Pre-attentive features are composite, primitive, and intermediate visual elements that are automatically recognized before entering our consciousness, typically within 10 ms after entering the sensory system
True
False
Next to the visual, the A (a) modality (sound) is perhaps the most prevalent mode for information feedback. The actual form of sound feedback can be roughly divided into three types:
(a) simple beep-like sounds, (b) earcons, and (c) relatively longer “as is”
sound feedback that is replayed from recordings or synthesis.
Intensity (amplitude) refers to the amount of sound energy and is synonymous with the more familiar term, volume.
True
False
(a) refers to the time differences among sound waves that emanate from the same source.
sound is effectively "omnidirectional". For this reason, sound is most often used to attract and direct a user’s attention. However, as already mentioned, it can also be a nuisance as a task interrupter (e.g., a momentary loss of context) by the startle effect.
True
False

So far, the aural modality has been explained only in the context of passive feedback.
As for using it actively as a means for input to interactive systems, two major methods are:
keyword recognition
natural language understanding.
the term H____ refers to the modality for sensing force and kinesthetic feedback through our joints and muscles, and the term T___ for sensing different types of touch (e.g., texture, light pressure/contact, pain, vibration, and even temperature) through our skin.
