Hospital environments are typically large, and even healthy individuals can need a navigation map. When we consider the combination of stress, concerns about health and convalescence, age and other factors that can affect hospital patients, it is clear that navigation can be a problem, and that assistance may be required. This paper focuses on the technical realization of an in-hospital navigation system tailored for users with limited orientation capabilities. A network of navigation spots throughout a hospital building is used to guide a user to his/her destination. A computer vision method is used for seamless user identification. Software and hardware implementation of navigation terminals, and also network communication, are discussed in this paper.
