A beacon-based user direction estimating method in indoor environments

Abstract

Applications using parts of a user’s body as an interface are increasing in number. In an indoor environment the location of a user can be measured using a beacon, and the direction of movement can be estimated from their location as measured by the beacon; however, a limitation exists when estimating the direction in which the user is facing. This paper proposes a method for estimating the direction of the user’s body using two beacons. It verifies experimentally that the proposed two-beacon method can correctly estimate the direction of a user’s body, with the error in the user direction reduced by 74.13% when compared to an existing method. © Springer Nature Singapore Pte Ltd. 2017.
