  The Internet of Things (IoT) can enable smart infrastructures to provide
advanced services to the users. New technological advancement can improve our
everyday life, even simple tasks as a visit to the museum. In this paper, an
indoor localization system is presented, to enhance the user experience in a
museum. In particular, the proposed system relies on Bluetooth Low Energy (BLE)
beacons proximity and localization capabilities to automatically provide the
users with cultural contents related to the observed artworks. At the same
time, an RSS-based technique is used to estimate the location of the visitor in
the museum. An Android application is developed to estimate the distance from
the exhibits and collect useful analytics regarding each visit and provide a
recommendation to the users. Moreover, the application implements a simple
Kalman filter in the smartphone, without the need of the Cloud, to improve
localization precision and accuracy. Experimental results on distance
estimation, location, and detection accuracy show that BLE beacon is a
promising solution for an interactive smart museum. The proposed system has
been designed to be easily extensible to the IoT technologies and its
effectiveness has been evaluated through experimentation.
