Apparatus and methods for bone conduction context detection
First Claim
1. A wearable device comprising:
- a first sensor to generate first vibration information from a bone structure of a user;
a second sensor to generate second vibration information from the bone structure of the user, the first vibration information and the second vibration information including sound data and motion data, the motion data indicative of motion by the user;
a signal modifier to generate a modified signal including the sound data based on the first vibration information and the second vibration information, the signal modifier to sum the first vibration information and the second vibration information to generate the modified signal; and
a communicator to transmit the modified signal to a speaker.

Abstract
Apparatus and methods for bone conduction detection are disclosed herein. An example wearable device includes a first sensor positioned to generate first vibration information from a bone structure of a user and a second sensor positioned to generate second vibration information from the bone structure of the user. The first vibration information and the second vibration information include sound data and motion data. The motion data is indicative of a motion by the user. The example wearable device includes a signal modifier to generate a modified signal including the sound data based on the first vibration information and the second vibration information. The example wearable device includes a communicator to transmit the modified signal for output via a speaker.
