摘要： This study aimed to evaluate how differently co-located users perform and interact while solving problems by using existing and newly developed interaction mechanisms of a multi-touch tabletop system on a large-size tabletop display. Furthermore, this study aimed to investigate users' perceived situation awareness due to the system. This study conducted one experiment and introduced three newly developed interaction mechanisms: two-way rubber band, drag-and-response, and centre collection area. Two-way rubber band enables users not only to send but also to request digital objects. Drag-and-response allows users to accept or to reject digital objects sent by others; therefore, it eliminates conflicting situations and interference. Centre collection area stores, organises, and manages shared digital resources on a surface of a tabletop display, so that users have an overall picture of available resources. This paper discusses results of an experiment, research findings, and implications along with conclusions and several suggestions for future development and research. 出版者： London: Taylor & Francis 出版日期： 2015-10-03 出處： Behaviour & information technology, 2015-10, Vol.34 (10), p.952-963 資源來源： EBSCOhost Business Source Premier 版權： 2014 Taylor & Francis 2014 版權： Copyright Taylor & Francis Ltd. 2015 識別號： ISSN: 0144-929X 識別號： EISSN: 1362-3001 識別號： DOI: 10.1080/0144929X.2014.942755
