Systems and methods for tracking motion and gesture of heads and eyes
First Claim
1. An apparatus configured for tracking head movement, comprising:
- a spatial orientation sensor configured for;
generating a first output of orientation of the spatial orientation sensor during a first rotation of a head of a user about a first axis, andgenerating a second output of orientation of the spatial orientation sensor during a second rotation of the head of the user about a second axis that is orthogonal to the first axis; and
a computing device comprising a processor and a memory communicatively coupled with the processor, wherein the processor is configured for;
determining an orientation relationship between the head and the spatial orientation sensor based on the first and second outputs.

Abstract
Apparatus, systems and methods configured for tracking head and eye movement are disclosed. In one example, an apparatus comprises an imaging sensor, a spatial orientation sensor and a computing device comprising a processor and a memory communicatively coupled with the processor. The imaging sensor is configured for capturing and recording images of an eye of a user when the user stares at a gaze point and rotates a head of the user about a first axis and about a second axis that is orthogonal to the first axis. The spatial orientation sensor is coupled to the imaging sensor such that the imaging sensor has a fixed position and a fixed orientation relative to the spatial orientation sensor and is configured for generating outputs during the rotations of the head of the user, wherein each of the outputs corresponds to one of the images of the eye.
