SpiderFeedback - Rope-based, visual feedback for orientation in Virtual Studios [DE]
The Virtual Sets and Virtual Environments Laboratory of the FH Düsseldorf developed and tested a new visual
feedback system for virtual studio applications. In order to evaluate the system, interviews with
experts were arranged.
The lack of stage furniture and visual clues hamper hosts' orientation in virtual sets.
By installing preview monitors, virtual studios try to overcome this hindrance.
Showing hosts or actors the composite image might provide an idea of their surroundings.
But such aids fail, when it comes to giving exact information about the virtual set.
For displaying a position of a virtual object in all three dimensions, a rope based
parallel manipulator was installed for testing purposes. It carries
a green ball in the center as a replacement. The manipulator was programmed to
communicate with the render engine to seek coordinates of a virtual
object in real-time. The coordinates were then used to position the green ball
accordingly. With this device, it is possible to show positions and movement of the
associated virtual object. Through the balls' colour and the transparent ropes, the device
can be keyed and therefore removed from the composed video. If demanded, it is possible
to cover the ball with graphics or a virtual object. The setup can be seen in several
videos, illustrating different applications. For comparability, the same tests were
conducted in advance with a preview display only. Subsequently the tests were repeated
with the SpiderFeedback alone. The evaluation was supported by markerless actor tracking
for auto masking and triggering animations.
