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.
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.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.
Response
A characteristic of a graphics tablet that determines how many times per second the tablet records the artist’s actions. The response rate is expressed in PPS (Points Per Second).
The higher the PPS value, the more responsive the surface is. If responsiveness is low, there is a possibility of getting jagged lines when working with the pen, and the stylus cursor may lag behind the movement of your hand. Devices with a response of
266 PPS or
more perform best, the “golden mean” is the range of values
230 – 233 PPS and
250 – 260 PPS, and in entry-level models the response can be
220 PPS or
less.
Control keys
The number of control keys provided on the pen. These keys can be used for various purposes — for example, changing the type or size of the brush for painting, switching colours, turning on the eraser mode, etc. The more keys — the more options the artist can switch on the fly without getting into the settings of the graphic editor, and the more advanced, usually, this pen is.
Power source
Power supply methods provided for in the device design.
Many graphics tablets can receive the necessary power via a USB port - directly from a computer or laptop. This option is often combined with standard mains power from a regular household outlet or autonomous operation of the device from a built-in rechargeable battery. All described power methods can be implemented separately in graphics tablets. Well, the least common options are powered by “finger” or “little finger” batteries (AA and AAA formats, respectively).
