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
Visual Modality
This is the angle subtended by the visible area by the human user in the horizontal or vertical direction.
Field of view (FOV):
This the perpendicular distance to the surface of the display.
Viewing distance
This is the angle subtended by the display area from a particular viewing distance.
Display field of view
A display system is typically composed of an array of small rectangular areas called
Pixels
This is the number of pixels in the horizontal and vertical directions for a fixed area.
Display resolution
The amount of light energy emitted by the object (or as perceived by the human).
Brightness
Human response to different wavelengths of light, namely for those corresponding
to red, green, blue, and their mixtures.
Color
Relative difference in brightness or color between two visual objects. (lightness or darkness)
Contrast
Next to the visual, the ____ modality (sound) is perhaps the most prevalent mode for
information feedback.
Aural modality
refers to the amount of sound energy and is synonymous with the more familiar term, volume.
Intensity (amplitude)
can be viewed as containing or being composed of a number of sinusoidal waves with different frequencies and corresponding amplitudes.
Sound
refers to the time differences among sound waves that emanate from the same source
Phase
This is the ability of a machine or a program to identify words and phrases in spoken language and convert them to a machine-readable format
Speech Recognition
It is a branch of artificial intelligence (AI) that uses computer software to understand input made in the form of sentence in text or speech format.
