Abstract
Inertial measurement units with gyroscopic sensors are standard in mobile computers. The present invention shows that these sensors can be co-opted for vibroacoustic data reception. The present invention illustrates a new capability for an old sensor utilizing the commodity gyroscope sensor found in most average smartphones and a low-cost transducer to the present invention can transmit error-corrected data at 2028 bits per sec with the expectation that 95% of packets will be successfully received.
Claims26
A method of transmitting data, through physical touching, from an object to a smart device comprising a gyroscope sensor, the method comprising:
- Configuring the object with a transducer that is capable of producing vibrations;
- and
- Configuring the transducer to transmit data through the vibrations,
- Whereby, when the smart device is physically touching the object, the gyroscope sensor detects the vibrations and the transmitted data.
A method of receiving data from an object that produces vibrations, comprising:
- Selecting a smart device comprising a gyroscope to receive data that is in the form of vibrations;
- and
- Touching the smart device to the object configured with a transducer that is configured to produce vibrations and to transmit data through the vibrations, whereby the data can be transmitted from the object to the smart device.
A system for transmitting data through physical touching, comprising:
- An object;
- A transducer that is associated with the object and capable of producing structured vibrations for transmission of data;
- and
- A smart device equipped with a gyroscope configured to receive the data from the transducer when the smart device touches the object.
A secure payment method comprising touching a smart device comprising a gyroscope, which smart device is configured to receive and translate data, to an object having a transducer, which transducer is capable of producing vibrations that transmit data,
- Whereby the touching of the smart device to the object enables the data from the object to be transmitted securely to the gyroscope.
A method of transmitting data, through acoustic coupling, from an object to a smart device comprising a gyroscope sensor, the method comprising:
- Configuring the object with a transducer that is capable of producing vibrations;
- and
- Configuring the transducer to transmit data through the vibrations,
- Whereby, when the smart device is acoustically coupled to the object, the gyroscope sensor detects the vibrations and the smart device converts the vibrations and data to information usable by the smart device.
