As with in-person conferences, you can approach anyone in the Virtual Chair venue to interact with colleagues. When you approach another participant, that person’s camera will appear at the top of your screen allowing you to converse. If you would like a more private conversation, you can sit at one of the tables in the lounge area. The number of chairs dictates the number of people who can interact with each other. If there are no empty chairs, no one else can join the conversation. Thus, if you want a one-on-one conversation, sit at a table with only two chairs.
