i-LAND

Abstract

~We describe the i-LAND environment which constitutes an example of our vision of the workspaces of the future, in this case supporting cooperative work of dynamic teams with changing needs. i-LAND requires and provides new forms of human-computer interaction and new forms of computer-supported cooperative work. Its design is based on an integration of information and architectural spaces, implications of new work practices and an empirical requirements study informing our design. i-LAND consists of several 'roomware' components, i.e. computer-augmented objects integrating room elements with information technology. We present the current realization of i-LAND in terms of an interactive electronic wall, an interactive table, two computer-enhanced chairs, and two "bridges" for the Passage-mechanism. This is complemented by the description of the creativity support application and the technological infrastructure. The paper is accompanied by a video figure in the CHI'99 video program.

Roles of Orientation in Tabletop Collaboration: Comprehension, Coordination and Communication

“…To facilitate manual orientation, several tables with pen-based input now provide users with lightweight rotation mechanisms, such as the circular pen ROLES OF ORIENTATION IN TABLETOP COLLABORATION gesture employed by the InteracTable (Streitz et al, 1999) and the ConnecTable Tandler et al, 2001). The DiamondSpin toolkit provides application developers the option of adding a rotation handle to the bottom-left corner of tabletop objects to enable manual rotation.…”

“…The InteracTable system automatically rotates objects as a consequence of a person ''tossing'' an information item to the other side of the table using a pen gesture. As the item moves across the table, it automatically rotates until it stops on the other side of the table, fully oriented towards the closest table edge (Streitz et al, 1999.…”

Algorithms for Smart Spaces

“…Some design-interactive conference rooms, offices, kiosks, and furniture with seamless integration between heterogeneous devices and multiple user applications have been constructed in order to facilitative collabo-Q1 rative work environments [11][12][13][14]. Abowd and Mynatt's work [15] focuses on ease of interaction with a smart space, and work such as the Gator Tech smart house [16] focuses on development of devices to support elder care.…”

Spoken language and multimodal applications for electronic realities

“…In FlatLand, an enhanced whiteboard provides space and history management, as well as supplying several automated 'behaviours' such as list manipulation and route-drawing cleanup [12]. In the i-Land system, a computer-augmented whiteboard allows collaborative development and sharing of documents in conjunction with other devices such as an 'InteracTable' and wireless mobile computers [13]. In the DigitalDesk project [14], documents placed or projected onto a desk can be manipulated with pens and with bare fingers.…”
