Various embodiments are described herein for an electronic device and associated method for detecting potential objects in the vicinity of the electronic device. In one example embodiment, the electronic device may comprise a transceiver arm including a transceiver for transmitting source signals and receiving response signals potentially indicating at least one object in the vicinity of the user, a main body that is pivotally connected to the transceiver arm to releasably mount to an article of the user during use and include at least one processing unit for generating a feedback control signal indicating when there is at least one detected potential object in the vicinity of the user based on the response signals； and a transducer movably coupled to the main body for providing feedback to the user based on the feedback control signal when there is at least one detected potential object in the vicinity of the user.
