1. Nike shoes- Aesthetic Consistency

When Nike shoes are designed they feature the logo in a prominent and visible position. This allows users to form an emotional bond with the brand and the product. This design

also allows users to associate the logo and product with a feeling of pride or prestige while they are using it(Lidwell, Holden, & Butler, 2010).


2. iTunes and Music Players-Functional Consistency

The play pause and skip buttons in digital music players such as the iTunes computer

program mimic the look and icons for the same functions on older devices. This allows people to make easy associations from a possibly familiar interface to a less familiar one(Lidwell et al., 2010; Suh, 1990).



3. ECU signs on campus-Internal Consistency


ECU sign- (picture taken by me)




The ECU signs on campus provide an example of internal consistency. The colour scheme used is the same, the fonts used are consistent and the layout is standardised. This makes the system more easy to understand and more uniform in its design implementation.





4. The Exit Sign-External Consistency

The Exit sign shown here is an example of external consistency. As a result of

conventions for signage and safety, disparate systems with no physical link would both be using this common sign to denote an exit. This allows for separate systems to maintain external consistency when required(Galitz, 2007).
