What You Need to Know About Virtual Reality Equipment

Virtual reality is often associated with gaming, but it also helps businesses support sales, facilitate learning, simulate travel and more. VR equipment includes headsets, input devices and sensors, plus computer software.

Fully immersive VR technology immerses the user in a simulated 3D environment using sight, sound and, in some cases, touch and smell. It can include omnidirectional treadmills for more freedom of physical movement.

Headsets

Virtual reality headsets are a key component of VR kits. They look like a pair of thick goggles that sit over the user’s eyes. Most VR headsets have a screen inside that displays simulated 3D images and video. They also have sensors that track the movements of the user’s head and hands. This information is used to interact with virtual environments and games.

The best VR headsets have a wide field of view that mimics natural human vision. This helps create an illusion of immersion, making the virtual reality equipment user feel as if they’re in another place or time. They also have high resolution screens and fast refresh rates to deliver sharp, smooth visuals.

Some headsets are tethered to a PC or gaming console, while others are stand-alone devices. Tethered models can run more processor-intensive games and offer higher resolution, but they’re harder to set up and more expensive. Stand-alone headsets are less expensive and easier to use out of the box.

Some headsets include hand controllers that let you interact with virtual worlds using the same gestures you would make in real life. Others have integrated headphones for immersive audio. Those with built-in sensors can even detect when you move your head and adjust the virtual content accordingly.

Input devices

Virtual reality (VR) is a fascinating technology that immerses the user in an alternate world. To enable VR to work, you need a headset that displays the virtual world, a tracking system that tracks the position of your head, and input devices that communicate your intentions to the computer that renders the VR experience. Input devices include keyboards and mice, but some are more advanced and can engage multiple senses.

For medical VR applications, input devices must be precise and comfortable. This is especially true for the medical use cases of liver surgery planning and craniotomy training, where a realistic hand position is critical to avoid incorrect muscle memory.

To determine the best input device for these tasks, participants were asked to perform a series of tests using four different input devices. These were then compared to find which performed the most effectively. The results were analyzed using one-way repeated measures ANOVA and post-hoc analysis using pairwise t-tests with Bonferroni correction.

A typical augmented reality system includes an infrared video-based tracker and a processor, such as a desktop computer. The processor determines the user’s point of view and then projects virtual objects onto the display device in proper reference to the point of view. It also enables the input device to interact with the virtual environment. For example, it can identify a marker board in the real world and then use that information to place virtual objects on top of the image displayed by the display device.

Sensors

Sensors are the devices that collect and transmit data from the physical world. These sensors observe changes in physical quantity like pressure, temperature or electrical quantities such as current and transmit those to a microcontroller or a computer for further analysis. Sensors can be either active or passive. Active sensors emit their own radiation or waves to detect the changes around them, while passive sensors detect the radiation or waves emitted by other objects in the environment.

There are a variety of sensors that can be used with VR headsets. Some are designed to track your position in the room and others are intended to provide haptic feedback. These sensors can be attached to a range of different accessories, including bags for carrying your VR gear and masks for absorbing dust and sweat.

Other sensors include force and tactile sensing units for HMIs that can be worn as a glove, for example. These sensors are used for human-machine interaction and can be powered by piezoelectric, resistive strain, capacitive or triboelectric technologies. They can also measure vibration and other physical parameters for robot control, physiological signal monitoring or industrial applications. Some of the latest models are even self-powered. This allows them to be embedded into wearables, which can make a person feel like they are truly present in the virtual world.

Output devices

Virtual reality output devices provide the user with information about the computer-generated world. These devices can include monitors, headphones, speakers and other hardware components. The monitor or projector displays visual elements, while the speaker produces audio output. This combination of visual and auditory information enhances engagement during presentations. Output devices can also be used in digital signage to convey information and advertisements.

While AR (augmented reality) adds digital elements to a live view, VR completely replaces the user’s real-world virtual reality equipment environment with a simulated one. This immersive feel makes VR an exciting tool for training, conferencing and convenience. It is also being utilized for sports, such as cycling, skiing and golf, to help improve performance.

The earliest VR systems consisted of a single large monitor, which took up the entire field of vision. More advanced headsets now feature a pair of monitors to produce stereoscopic views. However, most VR users prefer lighter mobile headsets that utilize lenses to separate the screen of a smartphone into two overlapping images for a 3D display.

While VR output devices can be limited, new technology is constantly in development to expand the capabilities of these devices. A scented display, for example, could allow users to engage their sense of smell as part of the experience. Other potential output devices include a full-body tactile suit that would satisfy all five of the body’s senses.
