This paper describes a studio that explores interfaces for computationally enhanced artifacts and environments.The studio is designed as a traditional architectural design studio, fostering creative thinking and encouraging hands-on learning. It brings students from art, music, architecture, computer science, and engineering together into teams to design and build physical computing projects.The team's unusual mix of knowledge and experience allows for creative solutions. As a result, the studio has become a test bed for new and interesting ideas. 170

We have designed a hub and strut kit that interfaces to a 3D graphics application. FlexM is a prototype flexible physical interface for manipulating and building 3D geometry. Using the FlexM hub and strut components, designers can build and explore 3D geometry with the ease of a toy and the power of a computer. The hubs transmit the model's topology and geometry to the computer, where the model is rendered on the screen in real time. The paper reports on the iterative development of several versions of the project.
The Navigational Blocks project demonstrates a tangible user interface that facilitates retrieval of historical stories in a tourist spot. Orientation, movement, and relative positions of physical Blocks support visitor navigation and exploration in a virtual gallery. The Navigational Blocks system provides a physical embodiment of digital information through tactile manipulation and haptic feedback. The simple cubic form of the Blocks is easy to understand and therefore easy to use to manipulate complex digital information. Electromagnets embedded in the Blocks and wireless communication encourage users to quickly rearrange the Blocks to form different database queries..H\ZRUGV Tangible interface, Information Navigation, Database Query ,1752'8&7,21Our physical environment is filled with subtle hints that help us to navigate and understand it. Unfortunately, most virtual environments do not provide these hints and it is challenging to design a means of navigating virtual worlds that offers them. The standard graphical user interface of windows, icons, menus and pointers is suitable for most tasks in accessing information to web sites, information kiosks, and automated tellers. However, mouse driven menus and buttons narrow the audience and limit interaction and creative exploration of the information.The Navigational Blocks interface steps beyond this conventional means of navigation, taking advantage of our understanding of physical objects to provide a means of navigation that encourages exploration. The child-like building block appearance makes the interface accessible to an audience that might otherwise shy away from a standard computer interface. Unlike a more traditional kiosk touch screen interface, we bring the navigational structure off the screen and into the physical environment, making a quick tangible understanding of the information available to the visitor. As a result, we provide users a true 'direct manipulation' experience with physical Blocks for easier interaction with and understanding of data space. Figure 1. The Navigational Blocks: electromagnets are visible on one face of the "Who" Block positioned on top of the 'active space' in front of the (smaller) host Block that is connected to a desktop computer (not shown).We first present a use scenario for the Navigational Blocks. Then we describe the design concepts, types of interactions among the Blocks, the system architecture and its implementation in hardware and software. Finally, we review related work on tangible media and discuss future research directions.
