In this picture, we see many people many people standing and sitting on the chairs. In middle, we see woman in white shirt is wearing handbag and standing. All of them are looking in looking into the looking at the system that is displaying something in it. To the left of this picture, we see wallpaper on which men and women are doing something. To the right we find lights and in the right middle the person is walking. I think this might be in auditorium.
