....Design Conference Room (DCR) 15] includes a Softboard TM whose software records activity as the user writes with a magic marker on the whiteboard surface. In addition to saving the final board image, the software can play back the strokes that created the image. XEROX PARC s DOLPHIN System [32] and Berkeley s Colab System [9] take whiteboards to a new level with liveboards which are essentially large touch sensitive computer displays. Handwriting recognition, sketching, and gesturing capabilities facilitate interaction with the device. The issue of public and private information is an ....

....of interaction focuses on how the software allows users to work together. Examples of coordination include floor control policies and social protocols. From a social perspective, poorly designed coordination will be ignored [129] or in the worst case, may interfere with the collaborative process [32]. From a technology standpoint, coordination can be broken down into components that provide group control and feedback about that control within the application. Human computer interaction evaluation of these components is necessary. Data associated with coordination can also be considered a form ....

....to question the fundamental designs that society has adopted as representative of a computer. Traditional interaction paradigms, such as the one keyboard one mouse paradigm can be constraining to users and are slowly giving way to more flexible technologies, such as large screen displays [20, 27, 29] and handheld computers [19] Still, these new technologies are not sufficiently addressing the needs of all users, specifically multiple children sharing machines in the classroom [12] Distance learning is currently a major research and industrial focus worldwide while the re design of hardware ....

....such as Lotus Notes, allow interaction with the workbase at the field level by having a database of objects that can be presented in different interactive views. But Notes does not offer a whiteboard style view that can be used in meeting settings. The system that is closest to ours is Dolphin [18], which also uses the LiveBoard. Dolphin offers a neat solution integrating the synchronous work in a meeting with the asynchronous work outside of meetings, but does this within a particular hypermedia model of nodes and links. Our approach is to integrate with a variety of different workbases ....

....annotations in Figure 5 move with the project views when the project list is sorted. Scribbles made on the board can be incorporated into domain objects in various ways. Any set of scribbles can be converted to an object by a box gesture around the scribbles (the same technique as used in Dolphin [18]) Domain objects can be tailored to absorb scribbles that are dragged onto their views and to pull scribbles in their spatial regions (which other systems cannot do) All these techniques allow users in meetings to easily shift between loose and structured modes of expression. Our overall ....

One is the type of databases that contain shared data on which the collaborative work is applied. This kind of database includes shared hypermedia systems[13, 20], repository database for software development (e.g. 14] etc. Databases of the other type contain process data.For example, a workflow management system may have a database that contains workflow process definitions and status of workflow cases. In this paper, we propose a new category of ....

....technologies based on real world artifacts that facilitate collaborative interactions. This approach combines existing collaborative tools from the physical world (e.g. a whiteboard) with the benefits of traditional computer technology. Interactive displays, such as electronic whiteboards [9, 13] and tabletop displays [14] are two alternative technologies based on real world counterparts. Electronic whiteboards and tabletop displays are natural choices since they are based on a shared surface metaphor, such as a typical office whiteboard or a table surface. This allows researchers to ....

.... these metaphors facilitate collaboration by providing surfaces large enough for multiple people to collaborate around without crowding, allowing unrestricted drawing and erasing that is essential for many informal collaborative tasks, and giving all group members access to the shared workspace [13]. 2.2 Alternative Interaction Devices Beyond display, the design of input devices and interaction styles can also help support natural collaborative interactions. Researchers have begun to look at alternative input devices that support computer interaction through the manipulation of physical ....
