All websites are somewhat interactive…we click on links or scroll a page, but truly interactive websites take us on a user-driven adventure or draws us in through motion and sound while giving us the power of choice. Interaction can be as simple as a series of clicks that navigate us through a story or landscape, or as complex as moving through a 3D environment to discover hidden content or reach goals to move to the next step. Put simply, interactivity is creating a user experience where the visitor is placed at the center.
