Ari introduces the concept of productive play and how playful experiences can exist in non-playful contexts like professional work. Some examples are the pull-to-refresh gesture in iOS and tapping the status bar to scroll to the top of a page, which feel playful through their animations and interactions. Siri also introduces playfulness through its personality. These small playful details humanize our experience with technology and help us emotionally connect with systems in a way that is important to our humanity. Play allows us to engage with objects and our environment through discovery, self-actualization and social interaction, and helps remind us that we are alive.
