Abstract
Free space machine interface and control can be facilitated by predictive entities useful in interpreting a control object's position and/or motion (including objects having one or more articulating members, i.e., humans and/or animals and/or machines). Predictive entities can be driven using motion information captured using image information or the equivalents. Predictive information can be improved applying techniques for correlating with information from observations.
Claims21
A method of capturing gestural motion of a control object in a three-dimensional (3D) sensory space, the method including:
- receiving observation information characterizing a surface of a control object from at least one image of a gestural motion of the control object in a three-dimensional (3D) sensory space;
- obtaining a 3D model that represents the control object, the 3D model comprising one or more 3D subcomponents fit to the surface characterized, wherein 3D subcomponents with least colliding subcomponents are fit to the surface;
- wherein colliding subcomponents exhibit at least one subcomponent attribute incompatible with an attribute of another subcomponent;
- and
- adjusting the 3D model responsive to an error indication between a point on the surface characterized and a corresponding point on at least one of the 3D subcomponents;
- and
- using the 3D model to facilitate control, communication and/or interaction with machines.
A non-transitory computer readable storage medium impressed with computer program instructions to capture gestural motion of a control object in a three-dimensional (3D) sensory space, which instructions, when executed on a processor, implement a method including:
- receiving observation information characterizing a surface of a control object from at least one image of a gestural motion of the control object in a three-dimensional (3D) sensory space;
- obtaining a 3D model that represents the control object, the 3D model comprising one or more 3D subcomponents fit to the surface characterized, wherein 3D subcomponents with least colliding subcomponents are fit to the surface;
- wherein colliding subcomponents exhibit at least one subcomponent attribute incompatible with an attribute of another subcomponent;
- and
- adjusting the 3D model responsive to an error indication between a point on the surface characterized and a corresponding point on at least one of the 3D subcomponents;
- and
- using the 3D model to facilitate control, communication and/or interaction with machines.
A system for capturing gestural motion of a control object in a three-dimensional (3D) sensory space, comprising:
- a processor and a non-transitory computer readable storage medium storing computer instructions configured to cause the processor to:
- receive observation information characterizing a surface of a control object from at least one image of a gestural motion of the control object in a three-dimensional (3D) sensory space;
- obtain a 3D model that represents the control object, the 3D model comprising one or more 3D subcomponents fit to the surface characterized, wherein 3D subcomponents with least colliding subcomponents are fit to the surface;
- wherein colliding subcomponents exhibit at least one subcomponent attribute incompatible with an attribute of another subcomponent;
- and
- adjusting the 3D model responsive to an error indication between a point on the surface characterized and a corresponding point on at least one of the 3D subcomponents;
- and
- using the 3D model to facilitate control, communication and/or interaction with machines.
