Contextual Location in the Home Using Bluetooth Beacons

Abstract

Location sensing is a key enabling technology for Ubicomp to support contextual interaction. However, the laboratories where calibrated testing of location technologies is done are very different to the domestic situations where 'context' is a problematic social construct. This study reports measurements of Bluetooth beacons, informed by laboratory studies, but done in diverse domestic settings. The design of these surveys has been motivated by the natural environment implied in the Bluetooth beacon standards relating the technical environment of the beacon to the function of spaces within the home. This research method can be considered as a situated, 'ethnographic' technical response to the study of physical infrastructure that arises through social processes. The results offer insights for the future design of 'seamful' approaches to indoor location sensing, and to the ways that context might be constructed and interpreted in a seamful manner.

An Empirical Study of the Transmission Power Setting for Bluetooth-Based Indoor Localization Mechanisms

“…The development of a BLE-based indoor localization make use of the RSSI reported by the mobile devices—then, followed by one of two main approaches: Triangulation [ 13 ] and fingerprinting [ 14 , 15 , 16 ]. Lately, other approaches, such as context [ 17 ] and crowdsensing [ 18 ], are also being actively explored. Despite the efforts being carried out by the research community, the robust development of wireless indoor localization mechanism remains a major challenge.…”

Indoor Positioning System With Cellular Network Assistance Based on Received Signal Strength Indication of Beacon

“…In (22), W is the weight coefficient column vector (4 × 1) which is determined by experiment result. The value of M are adjustable according to positioning environment.…”

Single UWB Anchor Aided PDR Heading and Step Length Correcting Indoor Localization System

“…Although the former mentioned INS solutions can improve the tracking distance at some extend, these solutions have not been tested and verified in long-term localization experiment, especially in high motion state. Except for INS-based localization system, radio frequency-based localization systems have been exploited sufficiently in recent decades, such as ZigBee [12], [13] WIFI [14], [15] Ultra-Wideband (UWB) [16], [17] Bluetooth [18], [19] and so on. These radio frequency-based localization system mainly adopt Received Signal Strength Indication (RSSI) or ranging information to estimation target position [20].…”
