For now, AR remains mostly a solo activity, but soon people might be using the technology for a variety of group activities, such as playing multi-user games or collaborating on work or creative projects.

University of Washington security researchers have developed ShareAR, a toolkit that lets app developers build in collaborative and interactive features without sacrificing their users' privacy and security. The researchers presented their findings Aug. 14 at the USENIX Security Symposium in Santa Clara, California.
