Professor Chen received the NSF CAREER award for her work on "Networked Multi-User Augmented Reality for Mobile Devices".  In multi-user augmented reality (AR), multiple users are able to view and interact with a common set of virtual objects. However, users can experience poor performance (such as high latency or inconsistent views of the virtual objects) due to the AR application's lack of advanced networking capabilities. This project seeks to address such issues by developing new network capabilities of the AR platform as well as tools to automatically measure multi-user AR experience.
