Wearable HCI device

An audio generation device includes a housing adapted to be worn by a user, memory, and a processor configured to execute computer-executable instructions. The device includes at least two of the following: an adhesive located on an outer surface of the housing to removably couple the housing to the body of the user, a transducer coupled to receive an electrical signal from the processor, convert the electrical signal to an audio signal, and supply the audio signal to the body of the user, a six degrees of freedom (6DOF) sensor coupled to detect translation of the housing along three perpendicular axes, and rotation of the housing about the three perpendicular axes, a biometric sensor coupled to detect at least one biometric parameter of the body of the user, a rechargeable battery removably coupled with the housing, and a wireless interface to transmit data via a wireless network.
