Format
The paper size that corresponds to the size of the tablet's active surface.
This parameter is specified only for traditional tablets and smart-notebooks (see "Type"). At the same time, the specific size of the device does not always strictly correspond to the specified format. For example, an
A4 tablet can be either a little larger or a little smaller than a standard landscape sheet of 210x297 mm. Nevertheless, according to the specified format, one can easily estimate the dimensions of the tablet as a whole and its general “weight category”.
Nowadays, on the market you can find devices in formats from A3 to A7, and the most popular options are the A4 mentioned above, as well as
A5(148x210 mm) and
A6(105x148 mm). In general, larger tablets are easier to use, but also more expensive.
Workspace
The exact size of the active area of a tablet (or screen in a graphic display) in width and height. In general, it is more of a reference than a practically significant parameter: when choosing a traditional graphics tablet, there is often enough information about the format (see above), and for displays, primarily the diagonal (see above) and aspect ratio (see below) are of practical importance . However, the exact dimensions can also be useful in fact: for example, you can determine the aspect ratio from them (for classic tablets, this parameter is often not indicated).
Control keys
The number of control keys provided in the design of the tablet.
Each of these keys is responsible for a specific function, while the set of these functions can be configured: in some models they can be selected manually, in others the functionality of the keys changes automatically, depending on the currently active application. Anyway, additional keys allow the user to perform various actions without looking up from the tablet — this can be very convenient in the midst of the work process, when you don’t want to change the pen to the mouse again or reach for the keyboard. And the more control keys — so, respectively, more additional actions can be performed using the tablet. On the other hand, with relatively simple tasks, the abundance of additional buttons can hinder and confuse the user rather than help.
The most modest modern tablets provide
up to 5 control keys ; the most popular option is
from 6 to 10 keys, and in advanced models this number can reach
15 or even
more.
Touch ring
The device has
a touch ring for quick control of popular parameters. By simply moving your finger around the ring, you can zoom and scroll in graphics applications, switch between layers, change brush size, rotate the canvas, etc. Note that the touch ring can have several operating modes, and a physical button in the center of the circle is often responsible for switching between them. In advanced devices, the ring can be reprogrammed for certain actions, and even sensitivity (scrolling speed) can be adjusted.
Connection type
Regular way to connect a tablet to a computer.
—
Wired. Wired connection, usually via a
USB port. This method is not very convenient: the wire limits the maximum distance from the tablet to the PC, and sometimes it has to be pulled to hard-to-reach places (for example, if the system unit is installed under the table with ports to the wall, and there are no available connectors on the front panel). On the other hand, in most cases, these inconveniences are not critical, and the wired tablets themselves are not as expensive as wireless ones, and besides, they do not require their own power supply.
—
Wireless. Wireless connection can be carried out in two main ways — either via
technology or via a dedicated radio channel. The first option is convenient because the tablet can be connected to any computer with Bluetooth — for example, a laptop or monoblock — without the use of special adapters; however, if there is no Bluetooth module in the computer, you will still need an adapter, and you will have to buy it separately. Models connected via radio, by definition, are equipped with an adapter and work only through it. Anyway, wireless tablets are more convenient than wired ones: the communication range usually reaches several metres, which allows you to freely move away from the comp
...uter (for example, draw in your favorite chair, holding the tablet on your lap). On the other hand, these devices are significantly more expensive, require their own power supplies, and have limited battery life.
— Wired/wireless. Models that support both of the connection options described above. Thus, they combine the advantages and partly compensate for the shortcomings of wired and wireless models. So, when the user is sitting right at the computer, the tablet can be connected with a wire and save battery power, and if freedom of movement is needed, the device can be disconnected and use a wireless connection. However, these models are not cheap.Connector on device
- microUSB. A smaller version of the USB connector designed for portable devices. Currently it is losing ground to the USB type C interface with a more convenient symmetrical contact group.
- miniUSB. Almost the same interface as described above, which differs only in the size and shape of the connector.
— USB A. Standard (full-size) USB connector used to connect the device to a computer and other external devices.
— USB C. A miniature version of the USB connector, gaining popularity and in the future capable of displacing microUSB. The interface has a high data transfer rate, and most importantly, it is symmetrical, so the plug can be connected to either side.
- Branded. A connection connector that does not belong to generally accepted standards and is used to a limited extent - in models of one or several manufacturers. However, due to general standardization, this option has practically disappeared from the scene.
Touch input
The ability to work on a graphics tablet with your fingers — just like on the touch screen of a smartphone or tablet PC.
Touch input can be useful both during "non-working" hours (for example, if the tablet is used as a touchpad for a PC), and when drawing, to implement some specific techniques. At the same time, note that the accuracy of typing with a finger is much lower than when using a pen.
Max. reading height
The height within which pen movements above the working surface are recorded by the tablet electronics even in the absence of direct contact.
Many tablets allow you to work in a "non-contact" way — without directly touching the stylus to the work surface. Thanks to this, it is possible, for example, with a raised pen to bring the cursor in the graphics editor to the desired point and turn on the drawing mode by touching the tablet with the stylus. And the greater the maximum reading height, the more convenient it is to use this mode, the less demanding the tablet is for the accuracy of movements. In many modern models, this parameter exceeds 10 mm.
Pressure levels
The number of pressure levels supported by the pen.
The more levels of pressure, the more accurately the pen tracks the force of pressure and the closer the drawing is to the drawing made by real tools like a pencil. The minimum value for a modern tablet is
512 levels, an indicator of
1024 levels is considered relatively small,
2048 is considered average, and in some models
4096 and even
8192 levels are found. At the same time, it is worth noting that the difference between pens with different accuracy becomes noticeable mainly on the thinnest strokes and on lines with a thickness that changes along the stylus; so numerous levels, even a professional artist is not always required. For this reason, this parameter has practically nothing to do with the general class of the device: for example, there are low-cost models on the market with 8192 levels, and professional solutions with only 1024.
