Abstract

An virtual character such as an on-screen object, an avatar, an on-screen character, or the like may be animated using a live motion of a user and a pre-recorded motion. For example, a live motion of a user may be captured and a pre-recorded motion such as a pre-recorded artist generated motion, a pre-recorded motion of the user, and/or a programmatically controlled transformation may be received. The live motion may then be applied to a first portion of an the virtual character and the pre-recorded motion may be applied to a second portion of the virtual character such that the virtual character may be animated with a combination of the live and pre-recorded motions.

Claims (40)

1. A system comprising:

at least one processor, wherein the at least one processor executes computer-executable instructions, and wherein the computer-executable instructions comprise instructions for:

receiving a pre-recorded motion and a live motion of a user;

mapping one or more body parts of a virtual character to one or more joints in a first model of the user associated with the live motion;

mapping one or more body parts of the virtual character to one or more joints in a second model associated with the pre-recorded motion; and

animating the virtual character with the pre-recorded motion and the live motion by at least:

disabling one or more joints in the first model of the user that correspond to one or more body parts in a second portion of the virtual character;

disabling one or more joints in the second model associated with the pre-recorded motion that correspond to one or more body parts in a first portion of the virtual character; and

blending the live motion associated with the first model of the user with the pre-recorded motion associated with the second model in response to the disabling the one or more joints in the first model of the user and the disabling the one or more joints in the second model;

animating the first portion and the second portion of the virtual character with the blended live and pre-recorded motions.

2. The system of claim 1 , wherein the pre-recorded motion comprises at least one of the following:

a pre-recorded motion of the user; an artist developed motion; and a programmatically controlled transformation.

3. The system of claim 1 , wherein the computer-executable instructions further comprise instructions for receiving a gesture from the user, wherein the gesture is associated with a command to apply an animation to the virtual character.

4. The system of claim 3 , wherein the virtual character is animated with the live motion and the pre-recorded motion in response receiving the gesture from the user.

5. A computer-implemented method comprising:

receiving a pre-recorded motion and a live motion of a user;

mapping one or more body parts of a virtual character to one or more joints in a first model of the user associated with the live motion;

mapping one or more body parts of the virtual character to one or more joints in a second model associated with the pre-recorded motion; and

animating the virtual character with the pre-recorded motion and the live motion by at least:

disabling one or more joints in the first model of the user that correspond to one or more body parts in a second portion of the virtual character;

disabling one or more joints in the second model associated with the pre-recorded motion that correspond to one or more body parts in a first portion of the virtual character; and

blending the live motion associated with the first model of the user with the pre-recorded motion associated with the second model in response to the disabling the one or more joints in the first model of the user and the disabling the one or more joints in the second model; and

animating the first portion and the second portion of the virtual character with the blended live and pre-recorded motions.

6. The computer-implemented of claim 5 , wherein the pre-recorded motion comprises at least one of the following:

a pre-recorded motion of the user; an artist developed motion; and a programmatically controlled transformation.

7. The computer-implemented of claim 5 , further comprising instructions for receiving a gesture from the user, wherein the gesture is associated with a command to apply an animation to the virtual character.

8. The computer-implemented of claim 7 , wherein the virtual character is animated with the live motion and the pre-recorded motion in response receiving the gesture from the user.

9. A computer-readable storage device having stored thereon computer-executable instructions comprising instructions for:

receiving a pre-recorded motion and a live motion of a user;

mapping one or more body parts of a virtual character to one or more joints in a first model of the user associated with the live motion;

mapping one or more body parts of the virtual character to one or more joints in a second model associated with the pre-recorded motion; and

animating the virtual character with the pre-recorded motion and the live motion by at least:

disabling one or more joints in the first model of the user that correspond to one or more body parts in a second portion of the virtual character;

disabling one or more joints in the second model associated with the pre-recorded motion that correspond to one or more body parts in a first portion of the virtual character; and

blending the live motion associated with the first model of the user with the pre-recorded motion associated with the second model in response to the disabling the one or more joints in the first model of the user and the disabling the one or more joints in the second model; and

animating the first portion and the second portion of the virtual character with the blended live and pre-recorded motions.

10. The computer-readable storage device of claim 9 , wherein the pre-recorded motion comprises at least one of the following:

a pre-recorded motion of the user; an artist developed motion; and a programmatically controlled transformation.

11. The computer-readable storage device of claim 9 , wherein the computer-executable instructions further comprise instructions for receiving a gesture from the user, wherein the gesture is associated with a command to apply an animation to the virtual character.

12. The computer-readable storage device of claim 11 , wherein the virtual character is animated with the live motion and the pre-recorded motion in response receiving the gesture from the user.
