1 Functions
The Visual Object Identification by Body (OSD-VOB) AIM receives a Visual Scene described by its Visual Scene Geometry and two Visual Objects – a Body Object and a generic Visual Object. The OSD-VOB AIM finds the Point of View indicated by the index finger of the Body Object and produces the Identifier – based on a Taxonomy – of the generic Visual Object that is crossed by the Point of View:
| Receives | Visual Object | Known to be a Body Object. |
| Visual Object | A generic Visual Object to be identified. | |
| Visual Scene Geometry | Geometry of the Visual Scene that includes the two Visual Objects. | |
| Processes | Body Object | To identify the Visual Body’s index finger. |
| Finds | Point of View | Defined by the direction of the index finger. |
| Produces | Identifier | Of the Visual Object crossed by the line corresponding to the Point of View. |

8 Conformance Testing
Table 3 provides the Conformance Testing Method for OSD-VOB AIM. Conformance Testing of the individual AIMs of the OSD-VOB Composite AIM are given by the individual AIM Specification.
Note that a schema may contain references to other schemas. In this case, validation of data for the primary schema implies that any data that refers to a secondary schema shall also validate.
Table 3 – Conformance Testing Method for OSD-VOI AIM
| Receives | Visual Object (Body) | Shall validate against Visual Object schema. Visual Data shall conform with Qualifier. |
| Visual Object | Shall validate against Visual Objects schema. Visual Data shall conform with Qualifier. |
|
| Visual Scene Geometry | Shall validate against Visual Scene Descriptors schema. | |
| Produces | Visual Instance ID | Shall validate against Instance ID schema. |
