This variation of Maslow's hierarchy of need is by Aarron Walter from an article over on the Think Vitamin blog. It describes the hierarchy of elements that work towards successful interface design. He has placed the element 'pleasurable' at the top of the chart, standing for emotional design.
He suggests that this top-level element of emotive consideration can only be implemented correctly if supported by a base of functionality, reliability and usability. As he says:
“Personality is the framework we use to crack jokes, empathize, and connect with other humans. If we can bake emotion into the interfaces we design, we reap big benefits.”This aspect of pleasure/delight is something I want to develop in my own interface designs.
