Chaining animations
First Claim
1. A method for chaining animations, the method comprising:
- receiving image data that is representative of captured motion;
selecting a pre-canned animation;
based at least in part on a transition point, generating a chained animation wherein;
the transition point is based, at least in part, on one or more parameters of the captured motion;
at least a first portion of the captured motion is represented by the pre-canned animation that replaces the first portion of the captured motion; and
at least a second portion of the captured motion is represented by an animation that corresponds to the captured motion; and
rendering the chained animation, wherein the chained animation comprises a blending of the first and second portions.

Abstract
In applications that display a representation of a user, it may be reasonable to insert a pre-canned animation rather than animating a user'"'"'s captured motion. For example, in a tennis swing, the ball toss and take back in a serve could be a pre-canned animation, whereas the actual forward swing may be mapped from the user'"'"'s gestures. An animation of a user'"'"'s gestures can be chained together into sequences with pre-canned animations, where animation blending techniques can provide for a smoother transition between the animation types. Techniques for blending animations, that may comprise determining boundaries and transition points between pre-canned animations and animations based on captured motion, may improve animation efficiency. Gesture history, including joint position, velocity, and acceleration, can be used to determine user intent, seed parameters for subsequent animations and game control, and determine the subsequent gestures to initiate.

1. A method for chaining animations, the method comprising:
-
receiving image data that is representative of captured motion; selecting a pre-canned animation; based at least in part on a transition point, generating a chained animation wherein; the transition point is based, at least in part, on one or more parameters of the captured motion; at least a first portion of the captured motion is represented by the pre-canned animation that replaces the first portion of the captured motion; and at least a second portion of the captured motion is represented by an animation that corresponds to the captured motion; and rendering the chained animation, wherein the chained animation comprises a blending of the first and second portions. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A system for animation blending, the system comprising:
-
a capture device configured to receive image data that is representative of captured motion; memory having stored therein computer-executable instructions; and a processor, wherein the processor is operable to execute the computer-executable instructions, and wherein the computer-executable instructions comprise instructions for; receiving image data that is representative of captured motion; selecting a pre-canned animation; based at least in part on a transition point, generating a chained animation wherein; the transition point is based, at least in part, on one or more parameters of the captured motion; at least a first portion of the captured motion is represented by the pre-canned animation that replaces the first portion of the captured motion; and at least a second portion of the captured motion is represented by an animation that corresponds to the captured motion; and rendering the chained animation, wherein the chained animation comprises a blending of the first and second portions. - View Dependent Claims (12, 13, 14)

15. A computer-readable storage device having stored thereon computer-executable instructions comprising instructions for:
-
receiving image data that is representative of captured motion; selecting a pre-canned animation; based at least in part on a transition point, generating a chained animation wherein; the transition point is based, at least in part, on one or more parameters of the captured motion; at least a first portion of the captured motion is represented by the pre-canned animation that replaces the first portion of the captured motion; and at least a second portion of the captured motion is represented by an animation that corresponds to the captured motion; and rendering the chained animation, wherein the chained animation comprises a blending of the first and second portions. - View Dependent Claims (16, 17, 18, 19, 20)
