“…Backed up by activity theory and the usage of AR, we developed groupware for layout planning and configuration tasks; this groupware is called the BUILD-IT system (Rauterberg et al, 1997a(Rauterberg et al, , 1997b(Rauterberg et al, , 1998Fjeld et al, 1998aFjeld et al, , 1998bFjeld et al, , 1998cFjeld et al, , 1999aFjeld et al, , 1999bFjeld et al, , 2000Fjeld et al, , 2001Fjeld, 2001). This system enables end-users, grouped around a table, to cooperate in the active design of a virtual setting, thus supporting co-located, instead of distributed, interaction.…”

Abstract. Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools -termed objectification -they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

“…Using the BUILD-IT system as a research platform for graspable interaction [8], our exploration takes the following path: Section 2 introduces some of the problems related to working in real and virtual environments, then indicates a few guidelines to achieve what we call natural interaction. Section 3 gives more details about the interaction content, which is configuration and planning tasks.…”

Abstract. BUILD-IT is a planning tool based on computer vision technology, supporting complex planning and composition tasks. A group of people, seated around a table, interact with objects in a virtual scene using real bricks. A plan view of the scene is projected onto the table, where object manipulation takes place. A perspective view is projected on the wall. The views are set by virtual cameras, having spatial attributes like shift, rotation and zoom. However, planar interaction with bricks provides only position and rotation information. Object height control is equally constrained by planar interaction. The aim of this paper is to suggest methods and tools bridging the gap between planar interaction and three-dimensional control. To control camera attributes, active objects, with intelligent behaviour are introduced. To control object height, several real and virtual tools are suggested. Some of the solutions are based on metaphors, like window, sliding-ruler and floor.

“…Among others, this type of interaction was described by Ishii and Ullmer (1997), Underkoffler and Ishii (1998) and Fjeld, Bichsel and Rauterberg (1998). Rauterberg, Mauch and Stebler (1996) showed that a brick based interface is significantly easier and more intuitive to use than mouse and screen based interfaces.…”

“…Finally, we describe some user experiences. In a first step, we have designed a partial Natural User Interface (NUI) instantiation (Figure 1), as described by Fjeld, Bichsel and Rauterberg (1998). Partial means that distributed communication between multiple systems has not yet been implemented.…”
