有许多移动的购物辅助工具和推荐系统可用，但没有一个可以轻松地用于当地超市的每周购物。我们提出了一个最小的，移动的和功能齐全的lambent显示器，夹在任何购物手推车处理，旨在推动人们在选择购买什么。它提供了关于各种扫描食品的食物里程的显著信息，这些信息由手柄上不同长度的发光LED和不断变化的表情符号表示，该表情符号将手推车中所有产品的平均里程与社会规范进行比较。当在现场进行评估时，lambent手柄显示器促使人们选择比他们使用普通购物策略选择的物品更少食物里程的产品。当人们购物车里的物品的平均里程超过社会标准时，他们也会感到内疚。研究结果进行了讨论，在如何提供不同种类的产品信息，人们关心，使用简单的发光显示器。
There are a number of mobile shopping aids and recommender systems available, but none can be easily used for a weekly shop at a local supermarket. We present a minimal, mobile and fully functional lambent display that clips onto any shopping trolley handle, intended to nudge people when choosing what to buy. It provides salient information about the food miles for various scanned food items represented by varying lengths of lit LEDs on the handle and a changing emoticon comparing the average miles of all the products in the trolley against a social norm. When evaluated in situ, the lambent handle display nudged people to choose products with fewer food miles than the items they selected using their ordinary shopping strategies. People also felt guilty when the average mileage of the contents of their entire shopping trolley was above the social norm. The findings are discussed in terms of how to provide different kinds of product information that people care about, using simple lambent displays.
