magine standing in front of a real estate agent’s shop window one evening. Look-ing at the computer driven display in the window, you see several interesting properties. You want to download the related information and leave your details so the staff can contact you to arrange viewings. You also want to scroll through the other properties, using all the features of the large public display. Of course, you want to interact with the display directly, and seamlessly move data between it and your own smart phone—and even have your phone become part of the real estate agent’s display. Com-posing the two displays would circumvent the need to learn new mappings and interaction techniques and, in essence, you could directly interact with this public display through your smart phone’s screen. Indeed, by observing users perform-ing tasks on other classes of situated displays, such as digital tabletops, researchers have noted the !uid mix of activities and rapid switching between tasks.
