In particular, the techniques presented herein use a secondary wireless device to collect a plurality of multivariate wireless data points within the spatial region. An artificially intelligent search algorithm analyzes the plurality of multivariate wireless data points to estimate the location of the wireless device. Directional instructions that guide the user to the estimated location of the primary wireless device are generated and then provided to the user. ## Claims ### Claim 1 A method, comprising: receiving, at a hearing device, Bluetooth® data packets from a plurality of wireless devices disposed in a same spatial region as the hearing device;
