HTC Vive Focus review: specs and price

Wireless devices allow users more freedom of movement.

Interpupillary distance (IPD) is the distance between the center of your eyes. Without adjustable IPD, the lenses of a VR headset may not line up with your pupils, which can result in eye strain and nausea.

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.

A wider field of view assures an immersive and realistic experience.

The frequency at which the screen is refreshed. Higher frequency results in less flickering (less noise) and more natural movement representation in action-intense scenes.

With adjustable lenses, the device can assure a sharp and clear image for a wide range of users, including users who usually wear glasses.

OLED (Organic Light-Emitting Diode) displays are formed of organic materials that emit light. They have higher contrast ratios and wider viewing angles compared to LCDs. AMOLED and POLED are types of OLED displays.

The device has an electronic display to present information to the user.

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.

The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.

As your head moves, the images move in real-time, assuring a realistic experience.

A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.

The device can track your position in space and warn you if you are about to hit something.

An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.

The gesture control function allows you to manipulate virtual objects.

The area of the surface that can be used for VR or AR simulations. A larger tracking area allows you more freedom of movement.

Newer USB versions are faster and have better power management.

More HDMI ports mean that you can simultaneously connect numerous devices, such as video game consoles and set-top boxes.

802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability, and improved power consumption. It provides advantages for gaming and HD video streaming.

Wi-Fi 4 (802.11n) is a wireless standard released in 2009. It has faster transfer rates and improved security compared to its predecessors – a, b, and g.

The device can connect to Wi-Fi.

With a standard mini jack socket, you can use the device with most headphones.

The device comes with a game controller.

Devices with integrated audio are more convenient to use, as you don't have worry about connecting headphones or microphones.

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

The device comes with handheld wireless controllers that are used for gesture control and/or movement tracking.

More microphones result in better sound quality and enable the device to filter out background noise.

It can support faster memory, which will give quicker system performance.

The upload speed is a measurement of the internet connection bandwidth, representing the maximum data transfer rate at which a device can send information to a server or another device.

DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

More memory channels increases the speed of data transfer between the memory and the CPU.

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
