Do you really want to strap a VR headset to your noggin after someone else wore it and worked up a sweat? Probably not. Acer thought of a better way—its new (and oddly named) OJO 500 mixed reality headset sports a detachable design that makes it easier to clean in between uses. > "The Acer OJO 500’s unique design enables the lens and head strap to be individually removed, making the headset easy to store and clean. This is especially beneficial for businesses who want to provide customers with clean headwear for each use," Acer explains.
