Conferences and meet-ups are excellent ways to dive in and learn about both VR/AR/MR companies and technologies. Additionally they often bring opportunities to try out new experiences (though you may need to wait in line). The Bay Area is extremely fortunate to have many meet-ups weekly, and conferences almost monthly.
A list of popular Bay Area meet-ups is below and new groups are added weekly. To contribute to bay area events calendar, email firstname.lastname@example.org. There are many VR/AR groups globally, check here for groups in your area.
