Architectures for processing of head tracking on a mobile device

A computer-implemented method, comprising:

• receiving motion sensor data indicating at least a motion of a computing device through a first hardware interface of the computing device, the motion sensor data being acquired during a first time period and at a first rate using at least one motion sensor of the computing device;
• storing the motion sensor data to a storage component;
• receiving image data indicating at least a location of a head through a second hardware interface of the computing device, the image data being acquired at an end of the first time period and at a second rate using a camera of the computing device, the second rate being slower than the first rate;
• retrieving the motion sensor data from the storage component;
• generating synchronized input data by processing, using at least one processor of the computing device, the image data and the motion sensor data, the synchronized input data including at least locations of feature points of the head and motion as represented by the motion sensor data;
• transmitting the synchronized input data to a publisher component;
• transmitting the synchronized input data to a polling component;
• causing, using the publisher component and at least an inter-process communication layer, the synchronized input data to be available as first event data to at least one listener client, the at least one listener client registered to receive the first event data;
• and
• providing, in response to a polling request from a pull client and using the polling component and at least the inter-process communication layer, second event data based at least in part on the synchronized input data.

A computing device, comprising:

• at least one processor;
• memory including instructions that, when executed by the at least one processor, cause the computing device to:
• receive motion sensor data indicating at least a motion of the computing device through a first hardware interface of the computing device, the motion sensor data being acquired during a first time period and at a first rate using at least one motion sensor of the computing device;
• store the motion sensor data to a storage component;
• receive image data indicating at least a location of a head through a second hardware interface of the computing device, the image data being acquired at an end of the first time period and at a second rate using a camera of the computing device, the second rate being slower than the first rate;

• generate synchronized input data by processing, using the at least one processor of the computing device, the image data and the motion sensor data, the synchronized input data including at least locations of feature points of the head and motion as represented by the motion sensor data;
• provide, to at least one listener client and using an inter-process communication layer, the synchronized input data as first event data, the at least one listener client registered to receive the first event data;
• and
• provide, in response to a polling request from a pull client and using the inter-process communication layer, the synchronized input data as second event data.
