Sword Health has filed a patent for a method to assess the positioning of trackers on a person’s body. The method involves transmitting instructions to the trackers to change their light emitter operation, capturing images using an optical sensing device, digitally processing the images to determine joint positions and tracker positions, and comparing the tracker positions with a predetermined configuration. The patent also includes a motion tracking system comprising the trackers, optical sensing device, and a computing device.

Method for assessing tracker positions on a person's body
A recently filed patent (Publication Number: US20230281831A1) describes a method for assessing the positioning of trackers on a person's body. The method involves using a motion tracking system that includes one or more trackers, an optical sensing device, and a computing device. Each tracker is equipped with a light emitter, a first antenna, and at least one inertial sensor. The computing device has a second antenna.
The method begins by transmitting an instruction from the computing device to at least one tracker, prompting a change in the operation of the tracker's light emitter. After this instruction is sent, the optical sensing device captures one or more images of the person, including the area where the trackers are positioned. The computing device then digitally processes these images to determine the positions of the person's joints and the trackers based on the emitted light and the transmitted instructions. Using this information, the computing device determines the specific body member on which each tracker is positioned. Finally, the computing device compares the positions of the trackers with a predetermined configuration to assess their accuracy.
Another aspect of the patent describes a method for assessing the position of at least one tracker on a subject. This method involves determining a target configuration for the tracker's position, activating the tracker's light emitter, and capturing an image of the subject using an optical sensing device. The computing device then automatically processes the image to determine the difference between the actual position of the tracker and the target configuration. This difference is then provided as an indication to the user of the computing device.
The patent also includes additional claims, such as the use of multiple trackers, providing alerts for incorrectly positioned trackers, offering user guidance for repositioning trackers, and repeatedly performing the assessment until the determined difference is below a threshold value. The patent also mentions the use of different light emission modes and colors for the trackers, as well as determining the identity of the body member on which each tracker is positioned. The trackers are equipped with antennas for wireless signal transmission and reception, and inertial sensors are used to compute angles and rotational orientations.
Overall, this patent describes a method and system for accurately assessing the positioning of trackers on a person's body using a combination of optical sensing, digital processing, and wireless communication.
