Products should be used as intended to be effective. Thus, product design must better incorporate possible user behavior. For example, sustainability-minded products should be both technically efficient, and support people to use such products more sustainably. In addition, many products and systems nudge people to behave in ways contrary to the user's best interests. To address the above, the course focuses on design that increases intended product use, and pro-social / pro-environmental behaviors. For projects, students will develop, prototype and test concepts that aim to increase desired behaviors.
