Abstract: A method to be carried out at an electronic device for detecting proximity to another electronic device is described. The electronic devices are capable of interaction through both low-accuracy sensing and high accuracy sensing. Low-accuracy sensing is used until a potential proximity event is detected. High-accuracy sensing is then activated, and attempts are made using high-accuracy sensing to detect a further potential proximity event corresponding to the potential proximity event. A determination is then made as to whether a proximity event has taken place—this is done using the further potential proximity event if detected, and using the potential proximity event otherwise. A suitable electronic device is also described, as is a method of training electronic devices to detect proximity to other electronic devices using a proximity estimation algorithm.
