Abstract

The subject disclosure is directed towards a sensor fusion interface that enables interaction between one or more entities of a physical environment and a computerized device component. A plurality of sensor modules generate multiple sensor input data associated with one or more entities in an environment and store such data in a shared library in accordance with a uniform and common schema. The multiple sensor input data is refined until a certain level of accuracy is achieved. Using the sensor fusion interface, entity state data is extracted from the shared library and exposed to the computerized device component.

Claims

1. In a computing environment, a method performed at least in part on at least one processor, comprising, processing requests received via a sensor fusion interface that enables interaction between one or more entities and an computerized device component, including, accessing a shared library that is coupled to a plurality of sensor modules, wherein the shared library comprises multiple sensor input data associated with one or more entities, extracting entity state data from the shared library, and providing the computerized device component with access to the entity state data.

2. The method of claim 1, wherein providing the computerized device component with access to the entity state data further comprises communicating an event corresponding to a change in entity pose.

3. The method of claim 1, wherein providing the computerized device component with access to the entity state data further comprises communicating one or more commands for the computerized device component from the one or more entities.

4. The method of claim 1, wherein providing the computerized device component with access to the entity state data further comprises generating control data based on the entity state data that corresponds to different points-in-time.

5. The method of claim 1, wherein extracting the entity state data further comprising determining a position and an orientation of a device being manipulated by the one or more entities.

6. The method of claim 1, wherein extracting the entity state data further comprises removing unwanted perturbations in the multiple sensor input data.

7. The method of claim 1, wherein accessing the shared library further comprises configuring the plurality of sensor modules to refine the multiple sensor input data.

8. The method of claim 1, wherein extracting the entity state data further comprises defining symbolic activity that translates into commands for the computerized device component.

9. The method of claim 1 further comprising updating the entity state data in response to entity movement.

10. The method of claim 1, wherein extracting the entity state data further comprises producing an environment model associated with the one or more entities.

11. The method of claim 1, wherein extracting the entity state data further comprises extracting a first portion of the entity state data associated with a first entity and a second portion of the entity state data associated with a second entity, and correlating the first portion with the second portion to determine entity interactions.

12. In a computing environment, a system, comprising, an interaction mechanism configured to provide a sensor fusion interface to an computerized device component, wherein, for each entity in an environment, the sensor fusion interface is configured to generate a profile comprising entity state data, to expose the profile to the computerized device component, and to instruct a common knowledge data component to update the profile in response to entity activity, wherein the common knowledge data component is configured to integrate multiple sensor input data from a plurality of sensor modules according to a schema, and to identify the entity activity based on the multiple sensor input data.

13. The system of claim 12, wherein the interaction mechanism is further configured to operate a computerized device in the physical environment based on the entity activity.

14. The system of claim 12, wherein the interaction mechanism is further configured to control a virtual character on a virtual environment that is generated by the computerized device component.

15. The system of claim 12, wherein the interaction mechanism is further configured to initialize the plurality of sensor modules in response to the computerized device component.
