Abstract:
In some implementations, a process for communicating data over audio is performed. In one aspect, one or more ordered sequences of audio attribute values that are selected based on a musical relationship between the audio attribute values and associated with data values may be played by a first device and received by a second device. This technique may allow for data communications to take place between devices without the need for the devices to include specific components (e.g. chipsets, antenna etc.) for communication via short-range radio frequency protocols such as Bluetooth or for wide or local area network infrastructure to be in place. Moreover, this technique may allow for sound-based communications that listeners may find pleasant.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing binaural navigational cues. In one aspect, a method includes presenting audio media in a non-directional playback state that presents the audible media in an original format, iteratively determining a navigational heading relative to a current navigational course, the navigational heading indicative of a direction to face to proceed along a navigational route, and for each iteration, determining whether a change is required to the current navigational course based on the navigational heading. For each determination that a change is not required to the current navigational course, presenting the audio media in the non-directional playback state, and for each determination that a change is required to the current navigational course, changing the non-directional playback state to a directional playback state that presents the audible media in a modified format that is directional from the navigational heading.
Abstract:
The present disclosure provides techniques for improving IMU-based gesture detection by a device using ultrasonic Doppler. A method may include detecting the onset of a gesture at a first device based on motion data obtained from an IMU of the first device. An indication of the detection of the onset of the gesture may be provided to a second device. Next, a first audio signal may be received from the second device. As a result, the gesture may be identified based on the motion data and the received first audio signal. In some cases, a first token encoded within the first audio signal may be decoded and the first token may be provided to a third coordinating device. A confirmation message may be received from the third coordinating device based on the first token provided and identifying the gesture may be further based on the confirmation message.
Abstract:
Among other things, this document describes a computer-implemented method. The method can include receiving, at a first device, an indication of user input to cause the first device to establish a wireless data connection with another device. A determination can be made at the first device that one or more sensors on the first device are oriented toward a second device. In response to at least one of (i) receiving the indication of user input to cause the first device to establish a wireless data connection with another device and (ii) determining that the one or more sensors on the first device are oriented toward the second device, a first wireless data connection can be established between the first device and the second device. A first stream of audio data can be received and played at the first device.
Abstract:
The present disclosure provides techniques for determining the position and/or orientation of a pointing device relative to the screen on a touchscreen device. A method may include receiving first orientation data from a first device that includes a capacitive touch surface. A touch point may be received indicating a location of a touch by a user on the capacitive touch surface. Second orientation data may be received from a second device. The first and second orientation data may be correlated to determine a relative orientation of the first device to the second device. A position of a pointing device may be determined based on the touch point and the relative orientation of the first and second devices. Additionally, multiple distances relative to a capacitive touch surface may be received, and based on the multiple distances, a position of a user's finger, hand, and/or arm may be determined.

Systems, methods and apparatus for using a magnetic controller to control device. In one aspect, a system includes a magnetic controller external to a device, the magnetic controller including: a magnetic device for altering a surrounding magnetic field of a device; one or more input actuators, each operatively coupled to the magnetic device and that when actuated cause the magnetic device alter the surrounding magnetic field according to a predefined change associated with the input actuator; and a model executable by the device and that models as device inputs the differences in the surrounding magnetic field of the device caused by the actuation of the one or more input actuators.
Abstract:
Methods for device pairing via a cloud server are provided. In one aspect, a method includes sending an initial signal from a first device to a second device. The method includes sending a notification from the first device of a set of communication capabilities of the first device. The method also includes receiving an indication of a common communication capability between the first and second devices. The method includes initiating pairing of the first device and the second device using the common communication capability in response to the received indication. Systems and machine-readable media are also provided.
