This presentation shares the journey I’ve been on, from trying to shape and influence a user’s path, to creating sandbox environments in which people can play and amaze us! ______ Designers are trained to guide users toward predetermined outcomes, but is there a better use of this persuasive psychology? What happens if we focus less on influencing desired behaviors and focus more on designing ‘sandboxes’: open-ended, generative systems? And how might we go about designing these spaces? It’s still “psychology applied to design”, but in a much more challenging and rewarding way! In this talk, I’ll share the journey I’ve been on, from trying to shape and influence a user’s path, to creating these sandbox environments. You’ll learn why systems such as Twitter, Pinterest, and Minecraft are so maddeningly addictive, and what principles we can use to create similar experiences. We’ll look at education and the work of Maria Montessori, who wrote extensively about how to create learning environments that encourage exploration and discovery. And we’ll look at game design, considering all the varieties of games, especially those carefully designed to encourage play — a marked contrast with progression games designed to move you through a series of ever-increasing challenges, each converging upon the same solution. Finally, we’ll look at web applications, and I’ll share how this thinking might influence your work, from how you respond to new feature requests to how you design for behavior change in a more mature way.
