For example, multi-touch tables have been not standardized, tabletop groupware systems are built for various purposes and the diversity of task activities constitute some of the challenges for enabling natural collaborative human computer interaction on multi-touch tables. While many studies have been conducted on individual problems, aggregate guidelines for designing an appropriate tabletop groupware system that can adapt to variable conditions are still under construction. In this paper we contribute some insights toward more general guidelines via an empirical study that sought to untangle the interrelated effects of ownership, individual collaborative strategies and workspace usage.enmensch und computer 2013 - workshopband
