Cadence Determination and Media Content Selection

摘要

Systems, devices, apparatuses, components, methods, and techniques for cadence determination and media content selection are provided. An example media-playback device comprises a media-output device that plays media content items, a cadence-acquiring device, and a cadence-based media content selection engine. The cadence-acquiring device includes an accelerometer and a cadence-determination engine configured to determine a cadence based on acceleration data captured by the accelerometer. The cadence-based media content selection engine is configured to identify a media content item based on the cadence determined by the cadence-determining engine and cause the media-output device to playback the identified media content item.

1. A media-playback device comprising:
a media-output device that plays media content items; a cadence-acquiring device comprising an accelerometer and a cadence-determination engine configured to:
capture a sequence of measurements from the accelerometer;filter the sequence of measurements based on frequency to generate a filtered sequence;calculate a first aggregate value corresponding to a period of oscillation of the filtered sequence over a duration;calculate a second aggregate value corresponding to a smoothing of the first aggregate value;determine whether the first aggregate value and the second aggregate value satisfy predetermined tolerances, wherein the predetermined tolerances include a difference tolerance and a duration requirement; andupon determining that the predetermined tolerances are satisfied, calculate a cadence value based on the first aggregate value; and a cadence-based media content selection engine configured to:
identify a media content item based on the cadence determined by the cadence-determining engine; andcause the media-output device to playback the identified media content item.
