Frequently Asked Questions About VR Headsets With a Magnetometer

A VR headset combines a stereoscopic display, stereo sound, and motion tracking sensors to produce an immersive virtual reality experience. The devices are mostly used in video games, simulations, and training exercises. Several major headsets are equipped with a magnetometer, including the Oculus Rift, the Razer OSVR, the Pimax 4K, the Acer WMR, the Dell Visor, the Lenovo Explorer, and the Samsung Odyssey.

What is the purpose of a magnetometer?

The new and used magnetometer VR headset on eBay refers to any device, such as a compass, that can measure a magnetic field. This device can take the form of either a permanent magnet or an electromagnet, which is generated only when an electric current is active. By measuring the intensity and the direction of the magnetism, the headset can accurately orient your direction.

That is not the only use for a magnetometer. The Google Cardboard, for instance, which contains a head mount of a smartphone, takes advantage of the magnetometer in a unique way. Although the smartphone is largely inaccessible inside of the head mount, the Google Cardboard contains a magnet that, once moved, registers as an input on the phone's screen.

How does a VR headset work?

These inexpensive VR headsets on eBay create a lifelike sense of motion with six degrees of freedom. This means the object is free to change position up and down, forward and backward, and left and right. Yaw, pitch, and roll are included as well. The typical virtual reality headset has multiple technologies working together at the same time to produce this effect: not just a magnetometer, but also an accelerometer, a gyroscope, and sometimes a proximity sensor.

How do you choose the right headset?

Here are some important characteristics to consider.

  • Resolution: The resolution determines the detail and clarity of the image. It is measured by the number of pixels, or dots, on the screen. A higher pixel count generally means more detail.
  • Latency: Latency refers to the time it takes to register a specific input, such as the motion controls. It is an especially important factor in virtual reality. If the system does not respond fast enough to a person's movement, then it could cause motion sickness. The typical latency of a headset is somewhere between 7 and 15 milliseconds.
  • Field of view: This is the extent of the observable world as measured in degrees.
  • Refresh rate: This is the number of times every second a display updates its image as measured in Hertz. The most common refresh rates are 60 Hertz, 90 Hertz, and 120 Hertz.
