E-Pawns (talking chess) is a version of this game which, thanks to the special tactile features of the chess board and the pieces, and the sound making, allows the game to be played by blind and partially sighted people. They are a combination of traditional Braille chess with a computer and modern technology. E-Pawns can be used without a power supply and without a built-in computer, like a normal game set. On the other hand, when they are powered up and the computer is activated, they become a combination of traditional chess, braille chess and computer chess, which, through the use of a physical chess board and runners (figures and pawns) as well as computer algorithms and voice communication, offer many advanced features.

A chess game is played on a typical 400 x 400 mm chessboard with fields measuring 50 x 50 mm. A computer is mounted under the chessboard. The fields of the chessboard are surrounded by an additional space 60 mm wide, on the upper surface of which are arranged the controls that function when the chess board is connected to the power supply and used as an electronic device. On the side of each player are buttons for confirming moves. On the other hand, the navigation buttons - up, down, left, right and the OK button - are located between the side edge of the chess board and the H4 and H5 boxes. These buttons are used to navigate through the menu and to change settings. On the same edge of the chess board, on each player's side, the chess clock displays have been placed.

E-Pawns has a built-in speaker. Through it, players can listen to voice messages generated by the computer. Currently, there is a soundtrack available in Polish and English. It is possible to add sound effects in other languages if required.

The chessboard fields and chess pieces have features that allow them to be distinguished by sight, touch and electronically.

Two game modes are available. In the first, the chess player moves the pieces and the chess computer immediately records the move, confirming it with a spoken message. In the second mode, the player moves the pieces and presses the move confirmation button on his side of the chessboard. Only after pressing this button does the chess computer recognise the move, check its correctness and confirm it. The desired mode is selected in the settings.

Once the computer has made its move, it instructs the chess player by uttering a message as to how the pieces should be rearranged in order for the computer's move to be considered on the chessboard.

The computer records the progress of the game. The situation on the chessboard can be saved at any time and then replayed to continue playing the game. The computer then instructs the players on how the pieces should be positioned and checks that the pieces are correctly positioned.

E-Pawns has been equipped with a USB port into which a memory stick with a software update can be inserted.
