S3nsibility evaluates using semi-immersive virtual reality to test pervasive environments before real-world deployment. It aims to address the high costs and challenges of testing sensor networks by creating a virtual replica where sensors can be deployed and their performance evaluated. Users would navigate the virtual space performing typical tasks while sensors gather data on activity hotspots and coverage. If the virtual testing matches real-world usage, the sensor configuration can be directly deployed, saving time and resources over real-world testing alone.

2. Ubiquitous Computing Ubicomp seeks to separate the user from the desktop for quotidian tasks An intelligent home or working environment can transparently save endless man hours for menial tasks and provide more productivity Ambient Intelligence devices are proliferating and the increased presence of wireless networks allows these apparatuses to flourish.

3. The Downside Deployment of a full scale Sensor Network is very expensive No guarantee that all devices will work to maximum potential or in sync with one another in the environment where they are installed Testing and configuration can take a very long time.

4. One Possible Solution Create and deploy sensors in a virtual environment Allow user to navigate through a familiar landscape Perform regular tasks and gather necessary information Deploy Sensors in a real environment using the gathered dataset If data collected is accurate, the sensor network should perform consistently

5. Approach Modify Half-life 2 Create custom maps e.g. UCD CASL 3 rd floor Create and deploy virtual sensors to gather information. Analyze Hotspots of user activity Configure components to leave no space “off radar” Install real-world sensors.
