“…Due to the convenience of paper documents, previous studies on media space have designed many systems for sharing paper documents across distances (Ishii et al, 1993;Wellner, 1993;Robertson and Robinson, 1999;Takao et al, 2001;Everitt et al, 2003;Paul et al, 2006;Izadi et al, 2007;Wilson et al, 2007). For example, Agora (Paul et al, 2006) projected an image of a remote partner's workspace on a local workspace and a life-size upper body image on a vertical screen that stands across the desk.…”

“…For example, Agora (Paul et al, 2006) projected an image of a remote partner's workspace on a local workspace and a life-size upper body image on a vertical screen that stands across the desk. Most systems project a partner's workspace onto a local desk (Wellner, 1993;Robertson and Robinson, 1999;Takao et al, 2001;Paul et al, 2006;Wilson et al, 2007) or present it on a tabletop display (Ishii et al, 1993;Izadi et al, 2007) to share paper documents. In such systems, the media inconsistency problem occurs since a paper document on the workspace is presented as a digital image in a remote workspace.…”

“…To share paper documents in remote collaboration more easily, many studies on media space have developed systems that simulate face-to-face collaboration in which users sit at the same desk and edit the same document (Ishii et al, 1993;Wellner, 1993;Robertson and Robinson, 1999;Takao et al, 2001;Paul et al, 2006;Izadi et al, 2007;Wilson et al, 2007). Figure 1A shows a typical system design.…”

Tangible document sharing: handing over paper documents across a videoconferencing display

Conventional techniques for sharing paper documents in teleconferencing tend to introduce two inconsistencies: 1) media inconsistency: a paper document is converted into a digital image on the remote site; 2) space inconsistency: a workspace deliberately inverts the partner’s handwriting to make a document easy to read. In this paper, we present a novel system that eliminates these inconsistencies. The media and space inconsistencies are resolved by reproducing a real paper document on a remote site and allowing a user to handover the paper document to a remote partner across a videoconferencing display. From a series of experiments, we found that reproducing a real paper document contributes to a higher sense of information sharing. We also found that handing over a document enhances a sense of space sharing, regardless of whether the document is digital or paper-based. These findings provide insights into designing systems for sharing paper documents across distances.

“…TeamWorkStation-2 (TWS-2) was designed to provide a shared workspace over narrowband ISDN (N-ISDN) Basic Rate Interface (2B+D) and the Primary Rate Interface (H1/D) using the CCITT H.261 standard of moving picture transmission [Ish93a]. We chose N-ISDN Basic Rate Interface as the target network because of its widespread availability in Japan.…”

“…(The latest version of TWS-2 is available via Ethernet as well as N-ISDN.) We conducted several controlled laboratory experiments as well as tests of real work outside of laboratories [Ish93a]. Before we started the TWS-2 experiments, many people felt dubious about the ability of INS-Net 64 to support real-time activities because of their previous experience with the jerky displays of video phones.…”

Computer Supported Cooperative Work, or CSCW, is a rapidly growing multi-disciplinary field. As personal workstations get more powerful and as networks get faster and wider, the stage seems to be set for using computers not only to help accomplish our everyday, personal tasks but also to help us communicate and work with others. Indeed, group activities occupy a large amount of our time: meetings, telephone calls, mail (electronic or not), but also informal encounters in corridors, coordination with secretaries, team workers or managers, etc. In fact, work is so much group work that it is surprising to see how poorly computer systems support group activities. For example, many documents (such as this book) are created by multiple authors but yet no commercial tool currently allows a group of authors to create such shared documents as easily as one can create a single-author document. We have all experienced the nightmares of multiple copies being edited in parallel, format conversion, mail and file transfers, etc.CSCW is not recent. Back in the late 1960s, Doug Engelbart created the NLS/Augment system that featured most of the functions that today's systems are trying to implement such as real-time shared editing of outlines, shared annotations of documents, and videoconferencing. The field really emerged in the 1980s and has been growing since then, boosted in the recent years by the explosion of the Internet and the World Wide Web. The Web itself is not a very collaborative system: pages can be easily published but it is impossible (or very difficult) to share them, e.g. to know when someone is reading a particular page or when a page has been modified. The range and complexity of the problems to solve to support cooperative activities is rapidly overwhelming: data sharing, concurrency control, conflict management, access control, performance, reliability, the list goes on.A large part of this book is devoted to the exploration of these problems and the state of the art of their solutions. In fact, CSCW is challenging most of the assumptions that were explicitly or implicitly embodied in the design of our current computer systems. CSCW tools, or groupware, are by nature distributed and interactive. To succeed in the marketplace, they must be safe (authentication), interoperable (from network protocols to operating systems and GUI platforms), fault-tolerant and robust (you don't want to be slowed down or loose your data if another participant in the session uses a slow connection or experiences a crash).In addition to these technical difficulties, there is another, maybe harder, problem in implementing groupware: people. For a medium to work, there must be an audience that accepts using it. Usability issues have stressed the need to take the users into account when designing, developing and evaluating an interactive software. For groupware, usability issues go beyond the now well-understood (if not always well-applied) methods from psychology and design. They involve social sciences to understand how people work...
