HOW TO USE A J-KEY,
KEYBOARD AND MOUSE
The J-Key is a communication device for people with severe disabilities who find it difficult to operate alternate keyboards such as the Lomak or Notesai. J-Key does not require extra software to run and reflects a plug and play USB keyboard.
SETTING UP THE J-KEY
​
-
Plug the J-Key into your computer’s USB port
-
Open up a blank ‘Word’document on screen
-
Download the Code for J-Key chart. This is a chart of the alphabet Letters and Colour Codes used with the J-Key. Place Code next to your blank MS Word doc as shown.
The J-Key uses a joystick to create, confirm and delete coded characters, in an easy and fluid manner.
The J-Key toggles between two modes of operation.
Mode 1 – Keyboard
Mode 2 – Mouse
MODE 1 - KEYBOARD
Mode 1 is the keyboard default setting of the J-Key. The 2 blue 'M' and 'C' lights should be off with this setting.
​
The following steps will allow a user to create letters and spaces.
​
To create the three one-character-code letters, move the joystick in one of the four directions.
e
Right hand direction
When the joystick is moved to the right, the yellow light will illuminate and a G will sound through the speaker. When the joystick is moved back to the centre position the yellow light will go out.
If the joystick is then moved to the top (Send) position, the white light will illuminate, a Top C will sound and a Letter T sent to the screen. The joystick is then returned to the centre position.
a
Top direction
When the joystick is moved to the top and back to the centre, without a previous character being selected, the white light will illuminate, a Top C will sound and a ‘Space’ will be generated.
y
Left hand direction
when the joystick is moved to the left, the red light will illuminate and a Middle C will sound through the speaker. When the joystick is moved back to the centre position the red light will go out.
If the joystick is then moved to the top (Send) position, the white light will illuminate, a Top C will sound and a Letter E sent to the screen. The joystick is then returned to the centre position.
t

When the joystick is moved to the bottom, the green light will illuminate and an E will sound through the speaker. When the joystick is moved back to the centre position the green light will go out.
If the joystick is then moved to the top (Send) position, the white light will illuminate, a Top C will sound and a Letter A sent to the screen. The joystick is then returned to the centre position.
space
More than one selection – when the joystick is moved to more than one position, the lights will illuminate and go out as they are selected. If the joystick is then moved to the top (Send) position, the white light will illuminate, a Top C will sound and a letter relating to the selection is sent to the screen. For example Red, Yellow, Green will generate a ‘Y’.
