How to Reuse Exisiting Interactive Applications in Ubiquitous Computing Environments?

In ubiquitous computing environments, we will access var-ious devices and appliances from a variety of mobile de-vices such as mobile phones, PDAs and wearable devices. However, we need to reuse existing interactive applica-tions that adopt traditional GUI toolkits that assume to use mouses and keyboards, and these applications should be operated from the mobile interaction devices. Our approach enables us to use existing GUI-based in-teractive applications although a variety of interaction de-vices can be adopted to control the applications. There-fore, the approach allows us to use traditional GUI toolk-its to build ubiquitous computing applications that choose appropriate interaction devices dynamically. The paper describes the design and implementation of our middle-ware to realize the approach. We also present some ex-amples to show the effectiveness of our approach
