Ergonomics

Designing products for comfort to suit people.

Anthropometrics

Taking measurements of human body to help designers create usable and comfortable products for majority of people.

Inclusively designed products

Made to be accessible for people between the 5th and 95th percentile, making it usable for 90% of people.

Implementation of anthropometrics

Can help improve the comfort of products, safety, reduce the risk of musculoskeletal disorders and in some cases, improve performance.

Aesthetics

Factors which can suggest the sense of beauty by appealing to the 5 senses (looks, feels, sounds, tastes and smells).

The Bauhaus

A famous design school which focused heavily on shapes and the understanding of design and tastes when creating products.

Colours

Can stimulate emotions and it also can excite or persuade.

The colour wheel

Was made by Sir Isaac Newton in 1666, and all the colours originated from the three primary colours: red, yellow and blue.

Colour Harmony

Colours next to each other in the colour wheel (red and purple for example).

Complimentary Colours

Colours opposite each other in the colour wheel (blue and orange for example).

Symmetry

Creates balance which creates a sense of harmony. It can be found a lot in nature but too much symmetry may become boring.

Proportion

Refers to the relative size and the scale parts of a design. It is the relationship between objects or parts as a whole.

Golden Ratio

Mathematical ratio found in nature that can be used to create pleasing and natural-looking structures.

Finish

Enhancement for function or aesthetics of products.

Dip Coating
