Implementing the physical web using Bluetooth low energy based beacons and a mobile app
Available at IEEE
It looks amazing as we are approaching the next big tech revolution of Internet of things, where billions of devices (sensors) would be connected to internet. But it seems unrealistic that to interact with each smart device, user would have to download a separate mobile/tablet application. In this paper we have come with an approach to deal with this issue using beacons.
Physical Web is an approach of Internet of Things which brings the feature of interaction on demand i.e. user can interact with the surrounding objects such as vending machine, parking meters, shopping stores, by just walking towards them, they need not to download a separate app for each of them.
Smart Office Energy Management System Using Bluetooth Low Energy Based Beacons and a Mobile App. Choi Moook, Park Wan-Ki, Lee Ilwoo
International Conference on Consumer Electronics (ICCE), pp. 501-502, 2015.
This paper describes a smart office energy management system (SOEMS) that can reduce the energy consumption of PCs, monitors, and lights in an office environment through the use of a mobile app and Bluetooth Low Energy based Beacons (BLE Beacons). BLE Beacons placed at several places in an office and a mobile app are used to determine whether a user enters or exits the office to change the power saving mode of the user's PCs, monitors, and lights. The proposed system can reduce energy consumption in the office without causing user inconvenience.
Location Fingerprinting With Bluetooth Low Energy Beacons. Faragher Ramsey, Harle Robert.

The complexity of indoor radio propagation has resulted in location-awareness being derived from empirical fingerprinting techniques, where positioning is performed via a previously-constructed radio map, usually of WiFi signals. The recent introduction of the Bluetooth Low Energy (BLE) radio protocol provides new opportunities for indoor location. It supports portable battery-powered beacons that can be easily distributed at low cost, giving it distinct advantages over WiFi. However, its differing use of the radio band brings new challenges too. In this work, we provide a detailed study of BLE fingerprinting using 19 beacons distributed around a ~600 m2 testbed to position a consumer device. We demonstrate the high susceptibility of BLE to fast fading, show how to mitigate this, and quantify the true power cost of continuous BLE scanning. We further investigate the choice of key parameters in a BLE positioning system, including beacon density, transmit power, and transmit frequency. We also provide quantitative comparison with WiFi fingerprinting. Our results show advantages to the use of BLE beacons for positioning. For one-shot (push-to-fix) positioning we achieve <; 2.6 m error 95% of the time for a dense BLE network (1 beacon per 30 m2), compared to <; 4.8 m for a reduced density (1 beacon per 100 m2) and <; 8.5 m for an established WiFi network in the same area.

Step and Play! Space as interface in the context of location based musical album apps.
Available at ACM
In this article, I intend to raise a debate on a very recent phenomenon of the music industry: the location-based musical album app. In this context, I discuss in which manners the physical public space can be interpreted as interface. The space mediates, reshapes and adds meaning to a site-specific musical album. The walking activity becomes the input that one needs to perform in order to encounter the output (music). The album listening is relative to the extension covered of these pre-designed territories.
