Abstract
A wearable device and system for detecting data generated by a user's contact with a surface and using that data to determine that a user contacted the surface and, in some examples, the location of the contact. The location of the contact may then be used by another device, such as an artificial reality headset, to select a user interface element, activate a function or perform a task in an artificial reality environment, or execute another type of function typically performed in response to an input to a user interface. In one example, the wearable device includes an ultrasound transmitter (Tx) and an ultrasound receiver (Rx). In some embodiments, the wearable device may also include a processing element capable of processing the signals detected or received by the receiver to determine that a contact occurred.
