SURG investigates a variety of issues in ubiquitous computing, including security, privacy and user acceptance. The key attributes of our target environment are:

• Sensors and processors embedded in the physical environment

• Mobile devices and users

• Collaborative applications

• Context-aware (physical and virtual) applications

• Non-technical users

We are currently investigating the following application domains:

• patient-oriented, health-care information systems
• minimizing inappropriate cell phone interruptions
• automatic service discovery for ubiquitous computing
• enabling common users to manage their own devices securely
