The object manipulator enables you to specify an object's origin (ie, the center of the physical object in relation to the marker pattern that is tracked by Tracker). You can also change the alignment of its local coordinate system (see [Change an object's alignment](https://vicon-help.atlassian.net/wiki/spaces/Tracker42/pages/258310986)).

1. Activate the object manipulator:
  1. To pause the live stream, press the space bar or click the **Enter Review**button at the bottom right of the **Workspace**.
  2. Select the object.
  3. In the **3D View**, click the object manipulator button.
    :check_mark: **Tip**: If you click on the object manipulator while not in Review mode, the dialog box does not appear until you click **Enter Review**.
2. Ensure Global or Local (either the local or global reference frame, as required) > Macro (inline-media-image)

 is selected. For details, see [Understand local vs. global reference frames](#LocalGlobal).
3. In the 3D View either:
  - Drag an axis to move the origin to the required location; or
  - Enter values in the **Translation** fields;
    When you resume streaming (ie, un-pause), the object's orientation is updated.
    :check_mark: **Tip**: To scale the Manipulator, on the numeric keypad, press + (scale up) or - (scale down).

Understand local vs. global reference frames

Note that the manipulator operates with respect to either the local or global reference frame (corresponding to the object coordinate system or the world coordinate system, respectively). To switch between the two:

- Click the required icon at the top right of the **Object Manipulator**.

Using the global reference frame, you can also move the origin of the object to the global origin by clicking **Translation** > Macro (inline-media-image)

.

If you use the local reference frame, note the following behavior:

- If you drag an axis, its translation in that axis is noted. When you start streaming again, this resets the local reference frame to this new location (ie, origin Translation is reset to (0, 0, 0)).
- If you enter a numerical value into one of the axis fields, the axis is translated by the specified amount. When you start streaming, the initial origin location persists so the translation still shows the amount specified for the remainder of that sync session.

After you have set the object’s origin, you can then align it further. For more information, see [Change an object's alignment](https://vicon-help.atlassian.net/wiki/spaces/Tracker42/pages/258310986).
