HCIQUIZ Flashcards
True or False. The human is the one whom computer systems are designed to assist.
True
There are five major senses: sight, hearing, touch, taste and smell. Which among the five major senses are the most important to HCI. Check all the apply.
Sight
Hearing
Touch
Part of the eye responsible for color vision
CONE
TRUE or FALSE.A low frequency produces a high pitch, a high frequency, a low pitch.
False
Stimulus received via receptors in the skin for heat and cold
thermoreceptors
The process of finding solution to unfamiliar task using knowledge
Problem Solving
It act as a “scratch-pad” for temporary recall
Short Term Memory
Repository for all our knowledge
Long term memory
A long term memory that is astructured memory offacts, concepts, skills
semantic
True or False. Abductive reasong are often unreliable because it can lead to false explanation
True
is when information is lost gradually but very slowly
decay
Information reproduced from memory can be assisted by cues. (categories, imagery)
Recall
It is structured in some way to allow access to information, representation of relationships between pieces of information, and inference
Semantic Memory
What are Long Term Memory Models. Choose 3.
Semantic Network
Frames
Production rules
It is affected by both the size of the object and its distance from the eye
Visual Angle
True or False.The auditory system performs some filtering of the sounds received, allowing us to ignore background noise and concentrate on important information.
True
True or False.The Maltron Left-handed keyboard is not designed to reduce fatigue for Repetitive Strain Injury.
False
True or False.Designers tend to assume fast processors, and make interfaces more and more complicated.
True
It converts bitmap back into text.
OPTICAL CHARACTER RECOGNITION
TRUE or FALSE.Direct view storage tube (DVST) are used in analogue storage oscilloscopes
True
The simpler version of SGML for web applications
XML
It uses lasers to read and sometimes write, and it is more robust than magnetic disk
Optical Disks
It use dictionary to ‘guess’ the right word.
T9 predictive entry
A type of scanner, the paper is placed on a glass plate and the whole page converted into bitmap.
Flat-bed scanner
A type of printer that use inked ribbon (like a typewriter)
Dot-matrix printer
Type of memory that is usually volatile;its contents are lost when the power is turned off.
RAM
A pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes.
Trackball
It softens the edges of line segments, blurring the discontinuity and making the jaggies less obvious.
ANTI-ALIASING
Used in desktop publishing for incorporating photographs and other images.
Scanner
Diagonal lines that have discontinuities in due to horizontal raster scan process.
JAGGIES
It composed of vast number ofcoloredor pixels in a rectangular grid.
SCREEN
It can be used to reduce the amount of storage required for text, bitmaps and video.
COMPRESSION
It is the most common text input device
KEYBOARD
These are screen/monitor that are smaller, lighter, and no radiation problems.
LCD
True or False.The interface designer does not need to be aware of the properties of the devices with which a system is built.
False
True or False.Electrostatic field leaks out through tube to user. Intensity dependant on distance and humidity and can cause rashes.
True
It involves at least two participants, the user and the system
INTERACTION
It defines the area of work under study.
domain
True or False.Goal is what you want to achieved or the desired output from a performed task.
True
These are operations or actions that you performed to achieve your goal.
TASK
What are the two major phases of interactive cycle?
EXECUTION AND EVALUATION
The study of the physical characteristics of interaction
Ergonomics
True or False.Menus are set of options displayed on the screen.
True
The way of expressing instructions to the computer directly.
Command Line Interface
True or False.The first spreadsheet is Lotus 1-2-3 followed by VISICALC.
False
A sophisticated variation of form-filling, it has grid of cells contain a value or a formula
SPREADSHEET
Default style for majority of interactive computer systems, especially PCs and desktop machines
WIMP Interface
It is used in multimedia, web browsers, hypertext and has minimal typing.
POINT AND CLICK INTERFACES
The area of the screen that behave as if they were independent, it can contain text or graphics.
WINDOWS
True or False.Slip is if you don’t know the system well and you may not even formulate the right goal.
False
It allows the user to move the contents of the window up and down or from side to side.
Scrollbars
True or False.Icons are small picture or image that represents some object in the interface.
True
These are key combinations from the keyboard that has same effect as menu item.
KEYBOARD ACCELERATORS
True or False.The physical design must look good (aesthetic) but it not cost too much (economic)
True
Information windows that pop up to inform an important event or request information.
