There are groups of people sitting on the chairs. Among them few people are holding the laptops. These are the tables, which are covered with the black clothes. I can see the laptops, bottles, papers, plate and few other things on it. Here is the man standing near the podium. This looks like a door with a door handle. I can see the screen with the display. These are the lights hanging. I think these are the banners. This looks like a tripod stand.
