Ubiquitous computing requires integration of physical space with

digital information. This presents the challenges of integrating electronics,

physical space, software and the interaction tools which can effectively

communicate with the audience. Many research groups have embraced different

techniques depending on location, context, space, and availability of

necessary skills to make the world around us as an interface to the digital world.

Encouraged by early successes and fostered by project undertaken by

tangible visualization group. We introduce an architecture of Blades and Tiles

for the development and realization of interactive wall surfaces.

It provides an inexpensive, open-ended platform for constructing

large-scale tangible and embedded interfaces. In this paper,

we propose tiles built using inexpensive pegboards and a gateway

for each of these tiles to provide access to digital information.

The paper describes the architecture using a corridor fa\c{c}ade application.

The corridor fa\c{c}ade uses full-spectrum LEDs, physical labels and

stencils, and capacitive touch sensors to provide mediated representation,

monitoring and querying of physical and digital content. Example contents

include the physical and online status of people and the activity and

dynamics of online research content repositories. Several complementary

devices such as Microsoft PixelSense and smartdevices can support

additional user interaction with the system. This enables interested

people in synergistic physical environments to observe, explore, understand,

and engage in ongoing activities and relationships. This paper describes the

hardware architecture and software libraries employed and how they are

used in our research center hallway and academic semester projects.
