COOK’S COLLAGE

Abstract

Many people regularly multitask while cooking at home. Juggling household chores, reusing limited kitchen utensils, and coordinating overlapping cooking times for multiple recipes can cause frequent task switching and simultaneous task monitoring while cooking. As a result, the cook occasionally loses track of his cooking progress especially when determining which ingredients have already been added, counting multiple scoops of an ingredient, and keeping watch of cooking times. People compensate for these memory slips by devising memory strategies or deferring to memory aids with varying degrees of success. In this paper, we present a novel memory aid for cooks called Cook’s Collage. We describe how the system constructs a visual summary of ongoing cooking activity. Then, we report a task simulation study evaluating the effectiveness of Cook’s Collage as a memory aid. We argue that a memory aid is helpful only if it is balanced correctly with a complementary memory strategy and only if the accuracy of the memory aid is trusted. Lastly, we discuss how the six design features of the Cook’s Collage suggest a general framework for memory aids in the home, which we term déjà vu displays.
