(B.N. Frank) Research has indicated that wearing Virtual Reality (VR) headsets can cause behavioral changes, balance issues, cognitive problems, eye problems (soreness, vision changes), headaches, and other discomforts. In fact, last summer Facebook recalled millions of VR face liners due to skin irritation complaints. Nevertheless, VR, AR (Augmented Reality), and now Mixed Reality (MR) headsets are increasingly being promoted and used for a variety of purposes including educational (see 1, 2), medical (see 1, 2, 3), employee and military training. Given its high price tag, we can only hope that the Army has figured out a way to make their AR headsets safe for its staff.
