ACM Symposium on Virtual Reality Software and Technology (VRST) 2021 will be a hybrid conference. All sessions will be hosted through an online platform. Some of the sessions will also be held on-site at Osaka University, located in Osaka, Japan. The Osaka area (and nearby regions like Kyoto and Kobe) is quite populous and lively, and there are many places to visit such as historical buildings, lively entertainment areas, and amusement facilities.
