Design in a way so that products have quirks and can be temperamental, indicating that the object has its own character and free will. Within Japanese philosophy, this would be considered Kami—‘spirit in everything’—whereby all artifacts are imbued with a soul. This can be achieved by designing for animacy by creating mechanisms that give the perception of character traits and expression, such as mimicking human behavior. This makes the interaction seem more intuitive while creating unexpected interactions, which generates richer moments of engagement with the product.
