1. A motion capture system comprising:
at least one sensor configured to obtain spatial data; a microcontroller coupled with said at least one sensor; a unique identifier associated with said microcontroller; a radio coupled with said microcontroller; an antenna coupled with said radio; a battery coupled with said at least one sensor, said microcontroller and said radio; a mounting board coupled with said at least one sensor, said microcontroller, said radio and said antenna; a closure cap comprising an outer portion and configured to cover said mounting board; a visual marker coupled with said outer portion of said closure cap, wherein said visual marker comprises a plurality of positionally offset visual elements positioned on a background color,
wherein said plurality of positionally offset visual elements are arranged in a non-linear pattern and are offset from each other,wherein said plurality of positionally offset visual elements do not overlap wherein said plurality of positionally offset visual elements comprises positionally offset dots or non-parallel lines or both said positionally offset dots and said non-parallel lines, wherein the plurality of positionally offset visual elements enable visual determination of a rotational orientation of the visual marker from a point orthogonal to a plane that passes through the plurality of positionally offset visual elements,wherein each of said plurality of positionally offset visual elements comprise differing visual characteristics than said background color, and,wherein said visual marker is configured enable an external camera to visually track said at least one sensor
to determine position and distance to said visual marker, andto determine a rotational characteristic of said visual marker; and, a computer, wherein said computer is configured to
display a location where said at least one motion capture element is currently placed or is to be placed on said user or said piece of equipment;prompt said user to move said at least one motion capture element that is currently placed or is to be placed on said location on said user or on said piece of equipment and obtain user input comprising said user moving said at least one motion capture element from said prompt to
associate said at least one motion capture element with assigned locations on the user's body or on said piece of equipment to acknowledge which motion capture of said at least one motion capture element said computer is requesting identity for; and,accept said data comprising an identity from said at least one motion capture element;obtain said identity of a particular motion capture element based on said data; and,assign said identity of said particular motion capture element to said location where said at least one motion capture element is currently placed or is to be placed on said user or on said piece of equipment based on said user moving said at least one motion capture element from said prompt; and, wherein said microcontroller is programmed to
obtain said spatial data from said at least one sensor, and,transmit
said unique identifier andsaid spatial data,via said radio and said antenna. |
