Abstract
An apparatus for directional acoustic sensing may include a wearable dimensioned to be donned by a user of an artificial reality system. The wearable may include a signal generator that propagates an acoustic wave via a body of the user toward a specific body part. The wearable may also include an acoustic sensor that detects an acoustic reflection of the acoustic wave propagated by the signal generator. The wearable may further include at least one processing device that is communicatively coupled to the acoustic sensor. The processing device may determine that the specific body part has made physical contact with an object based at least in part on the acoustic reflection. In response, the processing device may generate an input command for the artificial reality system that accounts for the specific body part making physical contact with the object. Various other apparatuses, systems, and methods are also disclosed.
