Holographic multi avatar training system interface and sonification associative training

A system comprising:

• a processor, coupled to memory, the memory including instructions, which when executed by the processor, cause the processor to:
• generate a first 3D avatar animation from captured movement of a user attempting a technique;
• retrieve a second 3D avatar animation corresponding to the technique;
• identify a first avatar size for the first and second 3D avatar animations and a distance between a reference point of the first 3D avatar animation and a reference point of the second 3D avatar animation;
• receive a user selection, separate from the captured movement of the user attempting the technique, the user selection including a second avatar size that is different from the first avatar size;
• automatically determine, based on the second avatar size, a change in the distance;
• and
• render the first 3D avatar animation and the second 3D avatar animation for display using the second avatar size and the change in the distance;
• and
• a display device to display the rendered first and second 3D avatar animations concurrently according to the second avatar size and the change in the distance.
