The ACM Symposium on Virtual Reality Software and Technology (VRST) is an international forum for the exchange of experience and knowledge among researchers and developers concerned with virtual reality software and technology. VRST will provide an opportunity for VR researchers to interact, share new results, show live demonstrations of their work, and discuss emerging directions for the field. The event is sponsored by ACM SIGCHI and SIGGRAPH. VRST 2015 will be held in Beijing, the capital of China. From the magnificent Palace Museum, also known as the Forbidden City, to the beautiful Summer Palace and the Great Wall, Beijing is the political, economic and cultural center of China for over 800 years from the Yuan Dynasty. The numerous royal buildings with long history endow it with incomparable charm. On the other hand, as the host city of the 2008 Olympic Games, this oriental ancient city presented her best fashion fascination to the world. The conference will be hosted by China State Key Laboratory of Virtual Reality Technology and Systems, School of Computer Science and Engineering in Beihang University (BUAA). VRST 2015 aims at bringing together VR researchers from around the world to present the state-of-the-art advances in this ever-growing dynamic area, and introducing VR research in China.
