Hand Model

The following videos show the difference between the traditional IK solution, and the hand model solution generated by our technique.

C-Major Scale

The following videos were generated by the system. The first uses only the IK solution, while the second uses the hand model extension. Notice how the first video looks mechanical and unnatural because the fingers are moving independently. In both videos, the guitar player correctly begins to play with the middle finger in order to minimize the wrist movement.

Chord Transitions

The guitar player algorithm is able to choose fingerings appropriate for playing chords. Bar chords are also handled by the system. The following videos demonstrate an example of the guitar controller integrating chord fingerings with single note-fingerings. Notice that in the video using simple IK, the middle finger doesn't move when it is not used leading to a stiff, mechanical look. The example using the hand model has the middle finger move and twitch even when it is not being used to play, leading to more natural looking motion.

Bar Chords

The following video shows the result of playing bar chords. The IK and the hand model solution are very similar because all the fingers are used in a stable configuration.
