Comparison BOBOVR Z6 vs Samsung Gear VR New

The largest diagonal of a smartphone compatible with the corresponding glasses (see "Intended use"). Note that this parameter can be specified both for universal models that do not have specialization for specific mobile phones, and for gadgets for specific devices (for more details, see "Compatible phone models"). The maximum diagonal is connected both with the features of the optics and with the physical dimensions of the "seat" for a mobile phone — a gadget that is too large simply does not fit there.

Note that even the smallest glasses for smartphones work quite correctly with devices with a diagonal of 5 – 5.5 ". So it makes sense to pay attention to this parameter if your device has a larger screen size. Nowadays, you can find glasses for gadgets 5.6 – 6 " and even 6" or more.

Models of mobile phones with which glasses of the corresponding type are initially compatible (see "Intended use").

This parameter is indicated for models originally created for specific smartphones — most often advanced flagship models; These glasses may not be compatible with other gadgets. On the one hand, this limits their application; on the other hand, the design may provide various specific features that are available only through close integration with a specific smartphone.

Also note that the characteristics may indicate compatibility not with a strictly defined model, but with a whole line — for example, iPhone. In such cases, it's ok to clarify which devices from the line are designed for glasses; the easiest way to figure this out is from the data on the maximum diagonal (see above).

The viewing angle provided by virtual reality glasses is the angular size of the space that falls into the user's field of view. Usually, the characteristics indicate the size of this space horizontally; however, if you need the most accurate information, this point needs to be specified separately.

The wider the viewing angle — the more the game space the user can see without turning his head, the more powerful the immersion effect and the less likely that the image will be subject to the "tunnel vision" effect. On the other hand, making the field of view too wide also does not make sense, given the characteristics of the human eye. In general, a large viewing angle is considered to be an angle of 100° or more. On the other hand, there are models where this indicator is 30° or even less — these are, usually, specific devices (for example, drone piloting glasses and augmented reality glasses), where such characteristics are quite justified given the overall functionality.

Presence in points of own built — in accelerometer.

The accelerometer is a sensor that records the accelerations that the device is subjected to. It performs two main functions: determines the position of the glasses relative to the horizon (in the direction of gravity) and monitors jerks and tremors (however, this function is secondary in VR glasses). Such a sensor is necessary for a full-fledged "immersion" in virtual reality, so it must be provided in glasses made in the form of independent devices (see "Intended use"). But models for PC / consoles may not be equipped with an accelerometer — this means that the glasses are not designed for classic VR, but for more specific tasks (for example, controlling a drone with a first-person view).

As for models for smartphones, most of them do not have this function, since all modern smartphones are equipped with accelerometers. However, there are exceptions — high-end models designed for specific devices: in them, the accelerometer can work in conjunction with a smartphone sensor, which ensures the most accurate image positioning.

The presence in the glasses of its own built-in gyroscope.

The gyroscope captures the direction, speed, and angle of rotation of the device—usually along all three axes. Without such a sensor, it is impossible to achieve a full-fledged "immersion" in virtual reality, so it is available in all standalone glasses, as well as in most models for PC / consoles (see "Intended use"). In the second case, the only exceptions are individual models with a specific purpose — "personal cinemas", glasses for piloting drones, etc. In turn, glasses for smartphones do not initially require gyroscopes, since smartphones themselves have such sensors. However, there are exceptions here too — advanced models created for specific top-level devices: in them, the built-in gyroscope works in conjunction with the gyroscope of the connected smartphone, ensuring maximum positioning accuracy.

The presence of a sensor in the glasses that reacts to approaching the user's face.

A similar sensor is used to automatically switch between operating and standby modes: for example, when the user takes off the glasses, the sensor turns off the built-in screens (or the phone, if it is connected to the glasses via a connector), saving battery power and equipment life, and when put on, it turns on points for full functionality.

The ability to adjust the interpupillary distance of glasses — that is, the distance between the centers of two lenses. To do this, the lenses are mounted on movable mounts that allow them to be moved to the right / left. The meaning of this feature is that for normal viewing, the centers of the lenses must be opposite the user's pupils — and for different people, the distance between the pupils is also different. Accordingly, this setting will be useful anyway, but it is especially important for users of a large or petite physique, whose interpupillary distance is noticeably different from the average.

At the same time, there is a fairly significant number of glasses that do not have this function. They can be divided into three categories. The first is devices where the lack of adjustment for the interpupillary distance is compensated in one way or another (for example, by a special form of lenses that does not require adjustment). The second is models where this adjustment is not needed in principle (in particular, some augmented reality glasses). And the third — the simplest and cheapest solutions, where additional adjustments were abandoned to reduce the cost.

The presence of a microUSB connector in the glasses. This is the most popular of the smaller versions of the USB connector, widely used primarily in portable technology. However, for a number of reasons, this interface is rarely found in VR glasses — in single models of glasses for a smartphone, as well as in some independent devices (see "Purpose"). In both cases, it is provided mainly for charging the built-in battery (glasses for smartphones can also have such power — for example, for the operation of built-in Bluetooth headphones).

The presence of a Bluetooth module in the glasses; The Bluetooth version to which this module corresponds can also be specified here.

Bluetooth is a technology created for direct wireless connection between various devices. This technology is found in all types of VR glasses (see “Purpose”), although most models with its support are independent devices. In any case, the most popular way to use Bluetooth in virtual reality glasses is to broadcast sound wirelessly. Moreover, the format of such a broadcast may be different, depending on the specifics of the glasses themselves. Thus, standalone devices broadcast the reproduced sound to external headphones. Models for PCs and smartphones may have built-in headphones, and here the sound is transmitted via Bluetooth to the glasses from an external device; Audio from the built-in microphone can be transmitted in the opposite direction.

In addition, there are other possible ways to use Bluetooth, such as directly exchanging files with another device or connecting game controllers. Such capabilities are found exclusively in stand-alone glasses; the specific functionality for each model should be clarified separately.

As for the versions, the oldest one used in VR glasses today is Bluetooth 3.0, the newest is Bluetooth 5.0. However, the differences between different versions for such devices are not fundamental; this information is provided mainly for reference purposes.
