Purpose and legal requirements for digital graphics

What are the purposes of digital graphics?

There are many uses and purposes for graphics in today's world across many different environments; some

of which are:

• Education
• Advertisement/promotion
• Entertainment
• Informational

Education

Graphics are used for educational purposes as they can present information visually meaning they can be interpreted easily, especially in contrast to alternative means of education such as long texts or videos.They are especially useful for audiences of younger ages who process information better via visual learning and this is noticeable with educational resources for children containing more graphics and images than those aimed at older age groups.

However, even educational resources for adults/young adults contain graphics as, in general, humans take in a lot of information through visual representation regardless of age.

Advertisement/promotion

It is extremely common for businesses, companies or even non-profits/charities to use graphics to advertise and promote what they are and what they do. These entities are always trying to get noticed, graphics help in this endeavour. Again, like the previous point (as well as the point to follow this one) humans take in information very well via visual representation but there are specific reasons why graphics are used for this purpose. One of which is that graphical advertisement/promotion gives unique identifiers to those who they belong to; this can include the colours, patterns, shapes etc. This means that, even subconsciously, people who see these graphics can recognise where, or who, it is from quickly.Consequently, this can increase the awareness of a brand, thus increasing how many people interact with them.

Entertainment

Graphics are also used for entertainment, simply put; it's because they are more interesting than alternatives (maybe because humans process information better visually?). Books, comics, games, animation and more; this applies to all ages. This runs hand in hand with advertisement and promotion, as most entertainment outlets are operated by businesses and graphics used at the forefront of an entertainment product is likely to draw attention from people - potential customers and consumers.Informational

Graphics are also used to inform people and give them information, and in some cases the purpose is to provide this information quickly. There are many examples of graphics used in the modern day to signify purposes or instruction to people; some along with text, some independent of text. Roads are a great example of where graphics are used to represent information and are used to how quickly this information can transfer to drivers; this is important as drivers travelling at high speeds may only see these signs for a short period of time. The three previous points, generally, are also included as informational, in some manner.
