Form Follow Functions

Form follow functions is a beauty in design that resulting from the purity of its purpose.

The function could be illustrate in two ways, first is according from the description of beauty and second is according from the prescription of beauty.

Form follow functions is a beauty in design that resulting from the purity of its purpose.

The function could be illustrate in two ways, first is according from the description of beauty and second is according from the prescription of beauty.

҉ Descriptive Interpretation:

Beauty results from the clarity of function

҉ Prescriptive Interpretation:

Aesthetic reflections in design should be secondary to purposeful reflections.

The purpose of this chair design have allow it to be stacked easily in spite of
the unique and beautiful style of the design.

Colour acts as the main role to make a design with the help of colour wheel tool. Colour helps to attract attention. Colour also plays main role to enhance the aesthetic part of the product which mean the combination of colour that been used in the design make it more visually interesting. However, if it is applied incorrectly, colour might harm the form and function the design itself. Therefore, we have listed 3 main rules for a good design in colour perspective.

1) Number of Colours

use color conservatively
use color purposely to attract attention
don't rely on color alone, use other attention
consider the color blindness

2 ) Colour Combination

Must use appropriate combinations of colors
Combining colour by using adjacent colour on the colour wheel, opposing colour on the colour wheel, colours at the corners of symmetrical polygon in the colour wheel or colour combined found in nature.
For instance;
Use warmer colours for foreground elements and cooler colours for background elements.

3 ) Saturation:

Using saturated colour when attracting attention.
Using de-saturated colour when performance and efficiency.
Bright colours usually perceived as professional and friendly.
Dark colours usually perceived as professional and serious.
Saturated colours usually perceived as exciting and dynamic.

Be cautious when combining saturated colour as they can interfere with each other and causes eye fatigue to increase.

Way Finding

Bako National Park Maps.

Way finding is involving environment information and spatial intelligent in order to navigate towards the destination.
Its involve four stages of process :

First is the orientation

The design help to find a location relative according to the nearby object and destination.
Shows easier routes to tell other where they are and where they can go.

Second is the route decision

To arrive at the destination, a decision have to been made by the user on which route need to be take.

Third is the route monitoring

The user need to monitor the path that have been choose is leading to the right destinations.

Forth is destination recognition

The user can identify the destination.
If the user can't identify the destination, the design can show the right way to reach the destination.

Classical Conditioning

Classical conditioning is a technique used to associate a stimulus. This could be done with an unconscious physical or emotional response.

This technique is used in design to influence the appeal of the design or influence a specific kind of behavior.

The image above shows a notification bar from a laptop, if the battery symbol turns red the owner will simultaneously find a power source to charge up the laptop or save up every task that were running on the laptop to prevent any data from missing.

Gestalt Principle of Perception

The gestalt theorist was the first group of psychologist to systematically study perception organization around the 1920, in Germany. The Principle of Gestalt describes how people organize visual elements into-groups or unified wholes when certain principles are applied.

It subsists of five principles:

Similarity

This principle identify a design which share visual characteristics such as shape, size, colour, texture, value or orientation will be seen as belonging together.

Picture above shows the similarity of the pattern, shape, size and the colour. It is to make sure the building is well build and have the same stability.

Continuation

This principle refers to when the learner's eyes are compelled to move through an object and continue to another object connected points from a straight line or a curving line.

Closure

This principal refers to objects that are grouped together are seen as a whole. Learners often see the object as a complete figure even though there are parts which are missing.

Picture above shows the AIRFORCE word isn't complete beacause the letter "O" is not there, but we understand the symbol it does represent the letter of "O" because we already familiar with this pattern in our life. .

Proximity

This principal refers to objects which are near to each other will be grouped together as one.

Picture shows the keypad that close together and it is related to each others. Keypad on this remote will be use for changing the channel or sending command to the Astro recorder. Each button at keypad has different letter or number but it is related to each others.

Figure and Ground

This principal describes the tendency of similar objects {figure} are contrasted with the non-similar objects {background} to give an impression of a whole.

Picture above shows that, the ice cream {figure} does bring out the main purpose of this advertising despite the background.
