Virtual Reality Equipment

Virtual reality equipment includes headsets that connect to computers to provide immersive simulations. The hardware also includes sensors and controllers that make it possible to interact with a fictional environment in the same way you would in the real world.

Engineers use VR to design and test prototypes without the expense of building and flying physical models. Teachers and students benefit from VR’s ability to simulate environments that are impossible or dangerous to visit in person.


Virtual reality headsets block out the real world and deliver a simulated environment for users. They can range from cardboard and a few lenses to sensor-filled LCD screen glasses packed with technology. Some of them offer head tracking, allowing the user to interact with the environment using handheld controllers.

The best VR headsets are tethered, like the Oculus Rift and HTC Vive, which connect to PCs or PlayStation consoles. They feature high-resolution displays, wide field of view and fast refresh rate to avoid motion sickness. Some of them also support 3D effects and immersive audio to add realism.

More advanced headsets include color passthrough cameras to add augmented reality to VR. The $1,000 Meta Quest Pro, for example, looks a lot like a pair of glasses and has color cameras that let you see your surroundings while wearing the headset. The upcoming Apple headset could have similar features, though it may be less expensive.

A few industries have taken advantage of VR for training, conferencing and convenience. For example, law enforcement trainers use it to simulate dangerous situations safely. This helps them avoid the expense of putting officers in actual dangerous situations and shrinks training timeframes. Companies use it to experiment with vehicle design and engineering before commissioning costly prototypes, and for data visualization. For instance, engineering and scientific data are displayed in stereoscopic VR images that look more realistic than flat screens.

Optical Trackers

Optical tracking is an alternative to inertial sensors and uses cameras to monitor movement. It’s based on binocular vision, meaning the system can see each side of an object at once and determine its position in space based on the difference in perspective. The technology is used in headsets to track rotational movements (roll, pitch and yaw) as well as translational movements (left/right and up/down).

Unlike head tracking, which can work with a variety of headsets, optical trackers need a specific headset or bodysuit to function correctly. They use multiple cameras to measure the pose of a user, converting them into data that can be processed by the virtual reality software. This information is transmitted to a headset through an IR signal that’s invisible to the human eye.

The accuracy of optical tracking systems is crucial. It needs to be within 1mm in scene virtual reality equipment coordinates, with a maximum of 0.1 degrees of error for orientation and jitter. The system must also be able to handle reflective surfaces and occlusions, which can cause inaccurate results.

NIST engineers helped develop tools that allow the testing of optical tracking systems. The toolkit consists of two barbell-like artifacts with a 300-millimeter bar at the center and six and two 3-D markers that can be detected by an optical tracking system. It’s the first time a standard test procedure has been developed for measuring the performance of VR optical tracking systems in a dynamic environment.

Motion Controllers

Virtual reality headsets require a range of input devices, including motion controllers that translate the user’s movements into actions within the VR environment. These devices come in a variety of forms, from simple two-button controllers to more advanced models that offer features like haptic feedback and hand tracking. They’re also used for gesture recognition and voice control.

To accurately track your movement, the device must be able to detect where you are in space. Most systems do this through a virtual reality equipment combination of base stations that emit synchronization pulses and IR photosensors in the controllers, which each have multiple IR sensors. The controllers start counting when one of their IR sensors is hit by the synchronization pulse, then send the corresponding position data to the system.

The system then calculates the precise movements that correspond to the detected sensors. It then signals the appropriate drives to move, adjusting their positions along each axis according to the programmed parameters. This is similar to the way a conductor orchestrates the movement of different musicians by providing the underlying tempo and signaling instruments to play as written.

The accuracy of motion controllers is especially important when implementing business VR simulations, where mistakes can cost companies dearly. The build quality is another factor, with poorly designed, slippery controllers causing them to slip out of your hands, which can make you feel uncomfortable and disorientated in the VR experience.


Virtual reality treadmills solve one of the biggest problems with VR today: being able to walk around in a virtual world. Without these machines, you can’t just stand up and move forward, and that would lead to running into things in the real world or knocking a chair over or someone else.

The Virtuix Omni One is the first omnidirectional VR treadmill that’s been commercially available. It reorients your position imperceptibly by changing a unidirectional treadmill into an omnidirectional one, and it also changes the speed of the treadmill according to what’s happening in the virtual world.

This product can be used by people with a wide range of body types, from very tall to small. It can be folded and easily kept in a closet or other restricted area between use, which makes it a good choice for those who want to get a full-body VR experience with the minimum of fuss.

While this type of VR gear is interesting, it’s also not for everyone. It’s expensive and needs a lot of space, which could be problematic for people who live in apartments or small homes where there may not be enough room to set up and use the device. Despite that, it’s still an impressive piece of VR equipment and something to watch out for in the future.
