Abstract	Billboards are everywhere, enabling users to interact by leaving documents, images, ads or clippings for others to see. There is currently no simple and transparent way to replicate this interaction pattern in a wall-sized display context. Users must first employ devices like scanners or digital cameras to digitize the content they wish to share. Then the digitized content must be manually transferred to some computer, before the user can display and arrange it on the desktop. This paper presents a system that supports the classic billboard interaction pattern in a display wall context. The user briefly holds the content to digitize anywhere in front of the display wall, and an image of it appears at the same location. The system comprises a 6x3 m high-resolution wall-sized display, a gesturebased human-computer interface and a ceiling-mounted steerable camera, which together enable transparent and low latency object imaging.
