1. Gestalt Theory for Computer Screen Design

2. Law of Balance
Visual object will appear incomplete if the visual object is not balanced or symmetrical.

3. Law of Continuation
Continuation is the eye’s instinctive action to follow a direction derived from the visual field.

4. Law of Closure
Open shapes make the individual perceive that the visual pattern is incomplete
Sense of incompletion serve as a distraction to the learner (Fisher and Smith-Gratto , Fultz, 1999)
CLOSURE

5. Law of Figure-Ground
We distinguish the foreground and background in a visual field (Fultz, 1999)

6. Law of Focal Point
Every visual presentation needs a focalpint, called centre of interest or point of emphasis.
This focal point catches the viewer’s attention and persuades the viewer to follow the visual message further (Lauer, 1979)

7. Law of Isomorphic Correspondence
All images do not have same meaning to us.
We interpret their meaning based on our experiences

8. Law of Pragnanz (Good Form)
The Cat
A stimulus will be organized into as good a figure as possible
The Cat

9. Law of Proximity
It states that item placd near each other appear to be a group (Fisher and Smith-Gratto, )
Figure A. We mentally arrange the dots into 3 horizontal rows because the dots in the rows are closely together than in the columns A B

10. Law of Similarity
The viewer can recognise the square inside the circle because these elements look similar and thus part of the same form (Fultz, 1999)

11. Law of Simplicity
The simplication works well if the graphical message is already uncluttered but if the graphics are complex and ambiguous the simplication process may led to unintended conclusion

12. Law of Unity/Harmony
If the related objects do not appear within the same form, the viewer will consider the separate objects to be unrelated to the main visual design.
(Lauer, 1979)
