With regular Augmented Reality engines its always a problem, that its not possible to change the real background behind a person to a virtual one – because the AR content is always in front of the real world’s content. (Apart from the case when the marker itself covers some part of it). Therefore it would be great to have a solution, where the person in the camera view could be defined and could be taken out and so force the background can be changed (like with the X-Box Kinect). We’ve started to experience with this and we have promising results – with the additional feature of the person being able to control the device by his hand gestures/body postures.
