Products should trigger emotional response.
Products and brands evoke certain feelings and associations based on how they look, feel, or smell. Think of the unmistakable sound of a Nokia ring tone. Or the pristine, leathery scent of a brand new Mercedes-Benz. Or the sleek, aesthetically pleasing lines of an iPod. Whether it’s annoyance or longing, products’ sensory qualities almost always evoke an emotional response.
