With emerging new technologies, the ways we buy things have become quicker and more transient: one-click or scanning, then all set. While efficient and useful, unfortunately, research has shown that it inadvertently influences people to mainly focus on material acquisition rather than being appreciative of experiential values—the joy of thinking about what they want to do with the purchased items or why the items are important to them. The pleasure sparked by material gain wears off quickly, failing to make people happier in the long run.
Pupal, a self-administered behavioral intervention technology, can be used when a user plans to spend money on something such as a hobby, gift, education, travel, or just a new cloth. When a user pushes the button, the device shows an adaptive question about the item the user intends to buy. Examples are: What do you want to say when you offer it?, How does this event contribute to your relationship?, What’s the first thing you want to do when you get there?, Where do you want to put it?, What’s the first thing you want to do with it?, and Who do you want to show it first?
The purchase intention can be communicated to Purpal by choosing an experience category represented by an RFID embedded card. The questions are printed on a small piece of paper that the user can put in her wallet or stick on a board, which allows the pleasure of answering the question resonate. In this way, Purpal enables, supports, and inspires people to engage in savoring their positive experiences that can be mediated by the items to buy, eventually enriching their purchasing experiences.
