This paper describes a simulation framework for sensor-based systems utilizing "Second Life", a popular virtual three-dimensional multi-user online world. With this platform, the components of a sensor-based system can be mapped to (or, represented by) virtual counter-parts. The intuitive user interface of Second Life and its comprehensive visualization support evaluation tasks of ubiquitous computing applications. Developers can directly control and manipulate virtual counterparts of real devices. In this way, different settings of a sensor-based system can be tested. The main contribution of our work consists of a bi-directional interface between sensor-based systems and Second Life.
