  • Patent number: 9316717
    Abstract: Methods and systems for determining and utilizing spatial correlative information relating to two or more devices to determine device positioning are described. Using audio signals emitted from stereo speakers, for example, associated with a first device and a microphone associated with the second device, the distance and angle between the two devices and as their relative positions can be determined. No other sensors or specialized accessories are needed on either device to calculate the distance and angles. The devices need only be loaded with the appropriate software which, when executed, is able to carry out steps of the present invention. The usefulness of one or both of the devices may be enhanced by knowing the distance and angle data between the devices. For example, one device may be a TV having stereo speakers and the other device may be a handheld device, such as a smartphone, having a microphone.
