Second Life Mixed Reality Broadcasts: A Timeline of Practical Experiments at the NASA CoLab Island

Abstract

Personnel at the Second Life NASA CoLab island have been experimenting with providing live, virtual world broadcast events for the benefit of the space and technology community. The broadcasts range from simple one-way stream feeds to more complex two-way interactive events. This paper will provide background information about the NASA CoLab, sketch an evolutionary timeline of experimental events held at the NASA CoLab island, and compare a couple of similar two-way mixed reality events.
