Scale independent tracking pattern

A computer implemented method of tracking and recording movement of an object having a scale-independent pattern of geometric shapes formed on at least a portion the object, the method comprising:

• capturing a plurality of images of an object during a capture period, the plurality of images including a first set of images of the object at a first resolution taken during a first segment of the capture period and a second set of images of the object at a second resolution, different from the first resolution, taken during a second segment of the capture period subsequent to the first segment;
• identifying and tracking a first portion of the scale-independent pattern at the first resolution from the first set of images as the object changes position during the first segment of the capture period;
• identifying and tracking a second portion of the scale-independent pattern at the second resolution from the second set of images as the object changes position during the second segment of the capture period;
• and
• mapping movement of the object during the first and second segments of the capture period to a motion model.

A non-transitory computer-readable memory comprising instructions that, when executed by a processor, perform a method comprising:

• tracking motion of a dynamic object bearing a scale-independent pattern of geometric shapes by tracking a first portion of the pattern at a first resolution;
• tracking a second portion of the pattern at a second resolution;
• and
• causing data representing the motion to be stored to a computer readable medium.

A system for capturing motion of an object, the system comprising:

• a camera;
• a display device;
• a computer-readable storage device having a computer program stored thereon;
• one or more processing devices operable to execute the computer program, interact with the one or more display devices and perform operations comprising:
• tracking motion of a dynamic object bearing a scale-independent pattern of geometric shapes by tracking a first portion of the pattern at a first resolution;
• tracking a second portion of the pattern at a second resolution;
• and
• causing data representing the motion to be stored to a computer-readable medium.
