Terms and Definitions:
• An autoTRACK Window is an invisible area in which your subject can move without the
camera following. If the person moves out of this defined area, the camera begins to
follow them again. The window is measured by the number of degrees of PAN/TILT from
the center of the window.
• The Window Reference is based on the center of your Pan/Tilt Window. It can be
referenced to either the center of the screen –”Center Reference,” or the person wearing
the Tracking Ring Sensor –”Sensor Reference.”
• The Subject Position refers to the subject’s location as it appears on the screen. This is
measured by the distance from the center of the screen. When the Subject moves outside the
Pan/Tilt Window, the camera resumes tracking the presenter at the Subject Position offset.
• The Screen is the area visible on the monitor.
If your presenter can walk off the screen before the camera begins following, you
may need to change the size of your Window or decrease the offset of the Subject
Position (see Figure 4).
Zooming in and out impacts your Subject Position. Zooming in causes the subject to
move toward the outer edge of the screen. Zooming out causes the subject to move
towards the center of the screen.
Tips to Adjusting the Parameters:
While in autoTRACK mode, the Pan/Tilt capabilities of the joystick are disabled, but you can still
zoom in and out. These tips can help you to keep your Subject from moving off the screen
while zooming in and out in autoTRACK mode.
1. Determine the physical area (presentation space) you need your camera to cover.
2. Ask your Subject to wear the Tracking Ring Package, power it up, and stand within the
presentation space at the point closest to the camera.
3. Press the autoTRACK button on top of the joystick to enable the camera’s autoTRACKing
functionality.
4. Zoom in on your subject.
5. Make your adjustments to the Window, Window Reference, Subject Position, and focus.
6. Ask your subject to walk around within the presentation area.
7. While the camera automatically follows the subject, zoom in and out to ensure that he/she
does not go off the screen.
