Hand chirality estimation for extended reality tracking

An extended reality (XR) device comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the XR device to perform operations comprising:
• processing tracking data captured by one or more sensors associated with the XR device to determine positions of a plurality of joints of a hand of a person;
• generating a reference vector based on at least a first subset of the positions;
• determining one or more angles based on at least a second subset of the positions, each of the one or more angles defined between a respective pair of articulating bones and measured in relation to the reference vector;
• identifying an estimated chirality of the hand based on the one or more angles;
• and
• causing presentation of content to the person in a content presentation format that matches the estimated chirality of the hand.

A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium including instructions that when executed by at least one processor, cause the at least one processor to perform operations comprising:

• processing tracking data captured by one or more sensors associated with an extended reality (XR) device to determine positions of a plurality of joints of a hand of a person;
• generating a reference vector based on at least a first subset of the positions;
• determining one or more angles based on at least a second subset of the positions, each of the one or more angles defined between a respective pair of articulating bones and measured in relation to the reference vector;
• identifying an estimated chirality of the hand based on the one or more angles;
• and
• causing presentation of content to the person in a content presentation format that matches the estimated chirality of the hand.
