Oulu Advanced Research on Service and Information Systems (OASIS) research unit studies information systems and service innovation. It focuses on how information systems and software can best serve people and organizations to perform personal, knowledge work and other important activities. Research is typically carried out by constructing new concepts and technology and then experimenting with it. Increased interactivity through modern ICT has opened opportunities for influencing user behaviors. For instance, fostering healthier lifestyles through web or mobile applications has become one of the most prominent areas for healthcare improvement. Other applications include greener energy behavior or stronger passwords for security. We study persuasive systems design: Computerized software or information systems designed to shape behaviors without using coercion or deception.
