VR headsets with magnetic button

Magnetic button

— a special control provided in glasses for smartphones (see "Intended use"). Usually, it has the form of a movable switch with a spring that returns it to its original state when released. The switch itself is located outside, but the magnetic field penetrates the body of the glasses and is perceived by a special sensor, which is equipped with almost all modern smartphones. Due to this, additional features appear in games and other tasks: for example, a magnetic button can be used as a trigger in shooting games, an accelerator in races, a switch between various modes, etc.
