We aim to support this typical work practice by introducing four tabletop direct-manipulation interaction techniques that can be used to transition the status of an electronic document from private to group-accessible. After presenting our four techniques {\textendash} release, relocate, reorient, and resize {\textendash} we discuss the results of an empirical study that compares and evaluates these mechanisms for sharing documents in a co-located tabletop environment.}, url = {http://portal.acm.org/citation.cfm?id=986085\&coll=Portal\&dl=GUIDE\&CFID=73988136\&CFTOKEN=37649975}, author = {Ringel, M. and Ryall, K. and Shen, C. and Forlines, C. and Vernier, F.D.} }
