Many user localization technologies and methods have been proposed for either indoor or outdoor environments. However, each technology has its own drawbacks. Recently, many researches and designs have been proposed to build a combination of multiple localization technologies system which can provide higher precision results and solve the limitation in each(More)
User localization is the key to enable many location-based services. Localization techniques have been actively studied recently due to service as well as safety and security matters. There are many localization systems with different architectures, configurations, accuracies and reliabilities. However, no technique is now generally applicable for indoor(More)
In this paper, a complete indoor navigation assistance system for visually impaired people is introduced. Different multimedia technologies are integrated in a single system in order to provide a precise, safe and friendly navigation service. First, the environment is modeled and represented. After that, the user location is determined by combining Wi-Fi(More)
This paper introduces and demonstrates a combination scheme for the combination of Wi-Fi based and camera based localization technologies to increase the applicability in indoor environments. The scheme is developed on the basis of an analytical approach by looking for maximizing the probability of appearance and the reliability of the location results(More)
