4 Identification
4.1 Product description and type
designation
DCZ is a dedicated keyboard used to control software
programs on Personal Computers.
This keyboard simplifies and rationalizes the user
interface quite remarkably and adds a joystick
and jog shuttle to the control system. It has been
conceived so that it can be used by both right-
handed and left-handed users.
Every time the operator uses the keyboard, it will
generate an event:
• Pressing of a touch key;
• Release of a touch key;
• Movement of the joystick;
• Movement of the jog dial;
• Movement of the shuttle ring.
All keys are totally independent. The pressing
and release of keys is recognised, whatever the
combination used. The software application will
interpret the command.
The keyboard also has an internal buzzer and
back-lighting for the keys. The software application
manages the buzzer and back-lighting of keys.
It can be connected to a PC together with other
standard peripherals (standard keyboard, mouse,
videogame joystick etc.).
Patent Pending.
