Abstract

Systems and methods are provided for registering a sensor assembly, implemented on a base apparatus, to a desired location associated with a head of a user. A position of a reference point on the base apparatus is determined relative to an external anatomical landmark of the user. A position of the external anatomical landmark is determined relative to the desired location. The position and orientation of the sensor assembly is determined relative to the desired location according to the determined position and orientation of the sensor assembly relative to the reference point, the determined position of the reference point relative to the external anatomical landmark, and the position of the external anatomical landmark relative to the desired location.

Claims

1. A method for registering a sensor assembly, implemented on a mouthpiece apparatus, to a center of gravity of a head of a user, comprising:

positioning the mouthpiece apparatus within a mouth of the user;

determining a position and orientation of each of a plurality of sensors positioned within the mouthpiece apparatus with respect to a known landmark on an anterior portion of the mouthpiece apparatus;

measuring a position of the known landmark on the mouthpiece apparatus relative to a tragion of the user a measurement tool;

estimating the location of the tragion relative to the center of gravity from one of a known relationship and anthropometric parameters,

determining the location and orientation of each sensor relative to the center of gravity according to the determined position and orientation of the sensor relative to the known landmark, the determined position of the known landmark relative to the tragion, and the position of the tragion relative to the center of gravity;

initializing the sensor assembly for the user with the determined location and orientation of the sensor assembly relative to the center of gravity.
