Method of tangible programming for applications in ubiquitous computing environment

In ubiquitous computing environments, management and creation cost of applications are important factors. In particular, to avoid the loss of time and high cost, systems by which users can create applications on their own are needed. In this paper, we describe a new programming method named "Plug & Program". It is a tangible, that is, real world, user interface that can create applications in ubiquitous environment. Plug & Program can easily be used to create applications in a ubiquitous environment
