Abstract	Large displays at home such as TVs are becoming larger in size and more interactive in functionality. When multiple co-located users share the screen space of a large display, when, where and how to display their media contents becomes an issue. This paper compares the use of automatic versus manual methods for managing personal screen real-estate on large in-home displays. We assume horizontally laid out "personal interaction spaces" as the user interface for multiple users to manage their screen real-estate. In this case, users need to sign in and out as well as have their personal spaces placed on the display. We constructed a computer-vision based system that tracks the identities and positions of multiple people in front of the display to support the user studies that compare the use of tracker-based mechanisms versus manual ones for managing the display. Our results suggest that the tracking system shows promise for a) simplifying the user registration process in conjunction with a manual sign-in/out process and b) effective tracker-based user-centric placement of people's interaction space. Proper integration of manual methods could improve the sense of control and ownership for users.
