The hands-free intercom may include a directional camera to capture video of the user and/or a directional video projector to deliver video to the user. The captured video may be provided to a remote entity and/or the delivered video may be received from the remote entity. The captured video may be used to identify vocal commands, gestures, facial expressions, and/or eye movements from the user. The projected video may be used to provide status information to the user.

Abstract: Aspects of the subject disclosure are directed towards a video-based pulse/heart rate system that may use motion data to reduce or eliminate the effects of motion on pulse detection. Signal quality may be computed from (e.g., transformed) video signal data, such as by providing video signal feature data to a trained classifier that provides a measure of the quality of pulse information in each signal. Based upon the signal quality data, corresponding waveforms may be processed to select one for extracting pulse information therefrom. Heart rate data may be computed from the extracted pulse information, which may be smoothed into a heart rate value for a time window based upon confidence and/or prior heart rate data.

Abstract: A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, and a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may determine whether the user is communicatively coupled via a mobile device to a remote entity. The hands-free intercom may be configured to receive a handoff of the communicative coupling, for example, by acting as a peripheral of the mobile device, by requesting the handoff, and/or the like. The hands-free intercom may be configured to deliver communications from the user to an appliance and vice versa.

Abstract: Techniques for ability enhancement are described. In some embodiments, devices and systems located in a transportation network share threat information with one another, in order to enhance a user's ability to operate or function in a transportation-related context. In one embodiment, a process in a vehicle receives threat information from a remote device, the threat information based on information about objects or conditions proximate to the remote device. The process then determines that the threat information is relevant to the safe operation of the vehicle. Then, the process modifies operation of the vehicle based on the threat information, such as by presenting a message to the operator of the vehicle and/or controlling the vehicle itself.

The hands-free intercom may determine whether remote entities requesting to communicatively couple with the user should be allowed to couple. The hands-free intercom may detect eavesdroppers and warn the user of the detected eavesdroppers.

Abstract: Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance a user's ability to operate or function in a transportation-related context as a pedestrian or a vehicle operator. In one embodiment, the AEFS is configured perform vehicular threat detection based at least in part on analyzing audio signals. An example AEFS receives data that represents an audio signal emitted by a vehicle. The AEFS analyzes the audio signal to determine vehicular threat information, such as that the vehicle may collide with the user. The AEFS then informs the user of the determined vehicular threat information, such as by transmitting a warning to a wearable device configured to present the warning to the user.

Abstract: Technologies pertaining to provision of customized audio to each listener in a plurality of listeners are described herein. A sensor outputs data that is indicative of locations of multiple listeners in an environment. The data is processed to determine locations and orientations of the respective heads of the multiple listener in the environment.

The customized audio signals are transmitted to respective beamforming transducers. The beamforming transducers directionally output customized beams for the first listener and the second listener based upon the customized audio signals and locations of the heads of the listeners.

Abstract: Technologies pertaining to improving an auditory experience of a listener are described. Audio is modified based upon noise generated by noise sources in an environment. A microphone generates a signal that is representative of noise in the environment, and the signal is processed to identify peak frequencies therein. When a key frequency of the audio is proximate to a peak frequency in the noise, the audio is modified to improve the listener's perception of the audio.
