Visual hierarchy www.mimos.my © 2008 MIMOS Berhad. All Rights Reserved. Visual hierarchy – Controlling user focus Definition “ Arrangement of elements according to importance and emphasis. Typically, this involves emphasizing certain elements in order to influence the user to look at and interact with a certain item first, another item second, yet another item third, and so on.” Sources: Lisa Graham, The Principles of Interactive Design, 1999 How to achieve?
