摘要： In this study, a Surface Computer Supported Cooperative Work paradigm is proposed. Recently, multitouch technology has become widely available for human-computer interaction. We found it has great potential to facilitate more awareness of human-to-human interaction than personal computers (PCs) in colocated collaborative work. However, other studies and modern operating systems have rarely been concerned with colocated interactions in their user interface (UI) design. Therefore, one UI framework, which we have named Surface Application Framework (SAF), is proposed to support multitouch and multiuser applications on tabletop computers. To explore the effects of wide area SAFs on colocated collaboration, one application, capable of making English sentences, was developed based on an SAF. This application was used to conduct a user-centric study to investigate differences between surface computers and PCs. The results show that a surface computer performs better than a PC in creating awareness during collaborative work, but it requires more time due to its poor performance with drag-and-drop operations. Finally, this study summarizes a three-dimensional design approach to consider various trade-offs between awareness and manipulative performances. Additionally, some mechanisms are suggested to be employed to overcome the weakness of drag-and-drop operations with multitouch interfaces in a future study. 出版者： Abingdon: Routledge 出版日期： 2012-04 出處： Interactive learning environments, 2012-04, Vol.20 (2), p.177-198 資源來源： Education Resources Information Center (ERIC) 版權： Copyright Taylor & Francis Group, LLC 2012 版權： Copyright Taylor and Francis Group, LLC 識別號： ISSN: 1049-4820 識別號： EISSN: 1744-5191 識別號： DOI: 10.1080/10494820.2011.554844
