This paper presents a system for interacting with digital information, called Triangles. The Triangles system is a physical/digital construction kit, which allows users to use two hands to grasp and manipulate complex digital information. The kit consists of a set of identical flat, plastic triangles, each with a microprocessor inside and magnetic edge connectors. The connectors enable the Triangles to be physically connected to each other and provide tactile feedback of these connections. The connectors also pass electricity, allowing the Triangles to communicate digital information to each other and to a desktop computer. When the pieces contact one another, specific connection information is sent back to a computer that keeps track of the configuration of the system. Specific two and three-dimensional configurations of the pieces can trigger application events. The Triangles system provides a physical embodiment of digital information topography. The individual tiles have a simple ...
