What we can do if the screen in videoconference rooms can turn into an interactive display? With Kinect camera and sound sensors, We explore how expanding a system’s understanding of spatially calibrated depth and audio alongside a live video stream can generate semantically rich three-dimensional pixels containing information regarding their material properties and location. Four features are implemented, which are “Talking to Focus,” “Freezing Former Frames,” “Privacy Zone,” and “Spacial Augmenting Reality.”
