Sensory marketing is a consumer behaviour science that looks at understanding subconscious triggers that embed perceptions about the product experience or quality. Packaging for example, can be used as a very effective medium to convey a message about a product. Sensory marketing used in product and packaging design can be a cost-effective alternative to traditional marketing. By simply engaging a range of human senses you can trigger and embed positive brand attributes through other tools than traditional advertising that relies only on visual or verbal cues. Some ofthe world's leading brands like Apple, Coca Cola or McDonalds, use it very effectively.
