FOUNDATIONS OF HCI Flashcards
interaction occurs through information being received and sent.
Input and Output
4 INPUT AND OUTPUT CHANNELS
- Visual Channel
- Auditory Channel
- Haptic Channel
- Movement Channel
3 MEMORY WHERE INFORMATION IS STORED
- Sensory Memory
- Short-term Memory
- Long-Term Memory
this influences human capabilities.
Emotions
is where input normally occurs in humans.
Senses
5 MAJOR SENSES
- Sight
- Hearing
- Touch
- Taste
- Smell
is a highly complex activity with a range of physical and perceptual limitation.
Human Vision
2 STAGES OF VISION
- Physical Reception of the Stimulus
- Processing and Interpretation of Stimulus
is a stage of vision where our senses are aroused/triggered.
Physical Reception of the Stimulus
is a stage of vision where our brain finally processes what the stimulus means.
Processing and Interpretation of Stimulus
has mechanisms for receiving light and transform it into electrical signal which are passes to the brain.
Physical Receptions
2 TYPES OF PHOTOTECEPTIONS
- Rods
- Cones
is a type of photoreception that is highly sensitive to light, allowing us to see in low light condition.
Rods
is a type of photoreception that is less sensitive to light, allowing us to see in bright light conditions.
Cones
this is affected by both the size of the object and its distance from the eye.
Visual Angle
is ability to perceive details (limited)
Visual Acuity
a subjective reaction to level of light
Brightness
is related to luminance.
Contrast
made up of three components: hues, intensity, and saturation.
Colour
3 COMPONENTS OF COLOUR
- Hue
- Intensity
- Saturation
is determined by the spectral wavelength of light.
Hue
is the brightness of the color. The brightness or dullness of a color.
Intensity
is the amount of whiteness in the color.
Saturation
compensates for the movement of the image on the retina.
Visual Processing
4 ACTIVITIES FOR THE SENSES
- Reading
- Hearing
- Touch
- Movement
in reading, this is a type of eye movement used to move the fovea rapidly from one point of interest to another.
Saccade
in reading, pertains to the maintaining of focus on just one location, perception occurs during here.
Fixation
3 PHYSICAL APPARATUS OF THE EAR
- Outer Ear
- Middle Ear
- Inner Ear
the visible part of the ear and protect the sensitive middle ear from damage.
Outer Ear
transmits sound waves as vibration to inner ear.
Middle Ear
where chemical transmitters are released and cause impulses in auditory nerve.
Inner Ear
in sound, this pertains to the sound frequency.
Pitch
in sound, this pertains to the amplitude
Loudness
in sound, this pertains to the type of quality
Timbre
3 PROCESSES OF THE MEMORY
- Sensory -> attention ->
- Short-term memory -> rehearsal ->
- Long-term memory
this exists for each sensory channel.
Sensory Memory
is the concentration of the mind on one out of a number of competing stimuli or
thoughts.
Attention
3 TYPES OF SENSORY MEMORY
- Iconic Memory
- Echoic Memory
- Haptic Memory
this type of sensory memory is for visual stimuli.
Iconic Memory
this type of sensory memory is for aural stimuli.
Echoic Memory
this type of sensory memory is for touch.
Haptic Memory
acts as a “scratch pad” for temporary recalls of information.
Short-Term Memory
is the main resource. Is intended for long-term storage of information.
Long-Term Memory
Information is processed and applied to (4)
- reasoning
- problem solving
- skill acquisition
- error
5 Effectors
- Limbs
- Fingers
- Eyes
- Head
- Vocal System
