Bluetooth sensors to make a "Senseable Space"
Bluetooth low energy (BLE) technology is able to reach the devices of every user is visiting a place. Thanks to its capability of providing information to the user and, at the same time, to track the user position, it enables a bidirectional exchange of information between the space and the user. What is necessary is just a mobile application able to connect with the beacons, and a few amount of sensors conceived among a visit path. This technology has been tested in Ancona in a public park called Cardeto. The application developed for this case study is CyberCardeto app, developed to enhance the visit path of the Cardeto Park in Ancona, Italy.
The localization services with GPS facilitate the orientation of the users within the park, where there are several historical and botanical Points of Interest to be discovered.
Thanks to the use of BLE technology, some beacons scattered among the area provide contextual information suggesting possible path and in depth analysis.
The objective is to valorize the fruition of public open spaces in an innovative way, creating a connection with the city. But it is no enough. Once the user get into the radius of influence of each beacon, the system is able to notice the human's presence and to collect information thanks to whom it is possible to analyze the users' behavior.
It is a great opportunity to make a space more interactive and at the same time to provide the local administration with useful information about how the park is exploited, becoming a fundamental decision making tool.
This mobile based technology enables to provide contextual notification to the users, so that their visit can be increased with more interaction. It also allow to collect statistics from the users (number of visitors, time spent in a certain place, interaction among groups), and to better understand the potential, performances and weakness point of a park. Two kind of users are involved with this kind of interaction: the visitors that can have a closer and deep knowledge of the space with digital information, and the landscape planners who can design in a more effective way the park.
The project was developed in close cooperation between SMEs, local administrations and academics.
