Augmented reality and virtual reality technologies are beginning to enter the mainstream, with applications ranging from training exercises for doctors to simulations for NASA engineers. However, AR and VR industry leaders also say that there remain some unsolved legal issues worth monitoring, particularly when it comes to health and safety issues and trademark and copyright enforcement.

Law firm Perkins Coie released its fourth annual “Augmented and Virtual Reality Survey Report” earlier this week, detailing the growth of the industry and also some of its risks. The survey, completed by 191 industry professionals in January and February, found growing optimism for AR and VR technologies’ long-term outlook, with more than 75% saying they expect immersive technologies to be mainstream within the next five years.
