Claim 16:
17. A system for monitoring a body position of a user, the system comprising:
a host device having a device wireless circuit;
a set of wirelessly locatable tags configured to be positioned along a body of the user, the set of wirelessly locatable tags comprising:
a first wirelessly locatable tag configured to be positioned along a first region of a back of the user and having a first battery and a first tag wireless circuit configured to transmit a first locating signal to the host device;
a second wirelessly locatable tag configured to be positioned along a second region of the back of the user and having a second battery and a second tag wireless circuit configured to transmit a second locating signal to the host device; and
a third wirelessly locatable tag configured to be positioned along a third region of the back of the user and having a third battery and a third wireless circuit configured to transmit a third locating signal to the host device each wirelessly locatable tag of the set of wirelessly locatable tags comprising:
a tag wireless circuit configured to transmit and receive wireless signals to and from the device wireless circuit; and
a battery operably coupled to the tag wireless circuit, wherein the system is configured to:

determine a first distance between the first wirelessly locatable tag of the set of wirelessly locatable tags and the host device by measuring a first transmission duration for the first locating signal transmitted between the host device and the first wirelessly locatable tag;
determine a second distance between the second wirelessly locatable tag of the set of wirelessly locatable tags and the host device by measuring a second transmission duration for the second locating signal transmitted between the host device and the second wirelessly locatable tag;
determine a third distance between the third wirelessly locatable tag of the set of wirelessly locatable tags and the host device by measuring a third transmission duration for the third locating signal transmitted between the host device and the third wirelessly locatable tag;
compute a position of a computer-generated avatar using the first distance, the second distance, and the third distance; and
cause a display the computer-generated avatar in the computed position.
