Abstract: A system for vibration-driven sensing may include a wearable dimensioned to be donned by a user of an artificial reality system. The system may also include a vibration sensor that is incorporated into the wearable and generates an electrical response that corresponds to a vibration detected at the wearable. The system may further include at least one processing device communicatively coupled to the vibration sensor. The processing device may determine, based at least in part on the electrical response generated by the vibration sensor, that the user has made a specific gesture with at least one body part. In response to this determination, the processing device may generate an input command for the artificial reality system based at least in part on the specific gesture made by the user. Various other systems and methods are also disclosed.

Abstract: A system may include a wearable dimensioned to be donned by a user of an artificial reality system. The system may also include an energy measuring device incorporated into the wearable. The energy measuring device may measure an electrical energy differential between a body of the user and a surface. The system may further include at least one processing device communicatively coupled to the energy measuring device. The processing device may detect, based at least in part on the electrical energy differential measured by the energy measuring device, an interaction between the user and the surface. In response to this detection, the processing device may generate an input command for the artificial reality system based at least in part on the interaction detected between the user and the surface. Various other systems and methods are also disclosed.
