ORIENTATION SENSITIVITY
Orientation sensitivity : Visual processing of line orientations, when certain orientations are more quickly and easily processed than others.
Oblique effect : Close to vertical or horizontal than ones that are oblique, leading to much lower accuracy when lines are oblique. This is because neurone are more sensitive to vertical and horizontal stimuli (because such lines are generally more important).
Example: Arrangement of chairs as shown below
Source: This picture was taken from Kolej Kenanga
Explanations:
The arrangement of the chairs are in a particular pattern which is facing towards right. However, oblique effect occurs when one of the chairs are arranged facing towards left since it has an obvious difference in its arrangement.
Pop-out effects : Some elements of a display ‘pop out’ and are easily and quickly detected. Lines that differ more than 30 degrees or more are easier to detect. This effect is caused when there is a change in visual stimuli that helps a person to see the difference in the orientations of line and patterns.
Example: Painting on wall
Source: This picture was taken at Penang Interactive Museum.
Explanations:
Due to the usage of lines in the painting that are of different degree, pop out effect occurs. The painting seems to be alive and has a three dimensional feel.
