The following table shows the data fields. For more information about the types shown in the type column, see MSDN PROPVARIANT structure.
| Property key | Type | Required/Optional | Description |
|---|---|---|---|
| PKEY_SensorData_AccelerationX_Gs | VT_R4 | Required | The x-axis acceleration in g's. |
| PKEY_SensorData_AccelerationY_Gs | VT_R4 | Required | The y-axis acceleration in g's. |
| PKEY_SensorData_AccelerationZ_Gs | VT_R4 | Required | The z-axis acceleration in g's. |
| PKEY_SensorData_Shake | VT_BOOL | Optional | An indication that a shake has been detected by the linear accelerometer. This must be true if the data field is sent up. |
