Superimposing Questioner on Presentation Screen Using Microphone with Whole-Sky Camera
Yuki Kobayashi, Kenji Funahashi · Eurographics · 2016
Academic conferences are usually held at a large hall. It is difficult that audiences watch the facial expression and gesture of a presenter there. Sometimes the presenter is shot by video camera and projected onto another screen, but it involves costs. At the same time someone usually asks a question there. However conference site is large as mentioned above, it is also difficult that audiences watch the questioner. Of course a conference staff can shoot the questioner and projects onto another screen, but additional manpower is required. Although it is not easy to install a camera at a conference site, a questioner generally uses a microphone. Then we consider projecting a questioner onto a screen using the camera built-in a microphone. In this paper we describe the pilot system to verify the effectiveness of this idea.
