New in paperback. Hardcover was published in 2018. The Handbook offers a comprehensive look at challenges to various legal doctrines raised by the emergence - and increasing use of - virtual and augmented reality worlds, and at how existing law in the USA, Europe, and other jurisdictions might apply to these emerging technologies, or evolve to address them. It also considers what legal questions about virtual and augmented reality are likely to be important, not just for judges and legal scholars, but also for the established businesses and start-ups that wish to make use of, and help shape, these important new technologies.
