The image shows a man standing in front of a green chalkboard in a classroom. He is wearing a white shirt and a blue lanyard around his neck. He has a beard and is holding a pen in his hand and appears to be speaking to another man who is standing next to him. The man in the green shirt is looking at the man with a serious expression on his face. In the background, there is a blue banner with the words "TU Wien" and "Information" written on it. There is also a white bag with a picture of a building on it, suggesting that the man is at an event or presentation.
