Tangible user interfaces (TUI) promise to enable natural and intuitive interaction with digital informa- tion through the physical environment. They are not limited to the interactions of a single person, but also support collaboration among ­ even dislocated ­ groups. Technological advances make it possible to integrate sensors and actuators as well as wireless communica- tion and processing technologies into everyday objects, and the vision of "everywhere interfaces" is coming within reach. In this report we briefly discuss the con- tents of the papers presented at the second international workshop on Tangible Interaction in Collaborative En- vironments (TICE), and summarize the main issues of the discussions. The aim of the workshop was to explore the potentials and perspectives of tangible in- teraction for supporting collaborative work, and it was held in conjunction with WETICE'07 in Paris, France, on June 18th 2007.
