Towards Understanding the Design Space of Tangible User Interfaces for Collaborative Urban Planning

摘要

This paper provides an analysis of the long-term, iterative design process of the ColorTable, a complex tangible user interface (TUI) supporting various stakeholders in collaboratively envisioning and discussing urban projects through constructing mixed reality scenes. The TUI has been iteratively designed, evaluated and redesigned in a series of real-world participatory design workshops over a 4-year period. We reflect on the most prominent redesign decisions related to (a) the sensing technology, (b) the physical objects, (c) the places for interaction and (d) the visual representations, in order to identify a series of 10 dimensions describing the design space of the ColorTable. Our aim is to provide new insights to the elaboration of design strategies of TUIs by describing the scope and complexity of the design space of a feature-rich TUI designed in a long-term, iterative process.
