The Cyberlink Interface is a communication link between humans and machines. Anyone wishing to explore the world of brain-actuated control can now operate computer software and any electrical device directly from the human control center - the mind.

The Cyberlink Interface enables hands-free control of computers and electrical devices. The Cyberlink system is easy,  fun to use and can be learned quickly. Strap on the headband, plug into your computer and let your mind do the rest.

Brain and body signals detected by the sensors in the headband are amplified, digitized and transmitted to the computer as multiple Brainfingers to affect feedback displays, control a mouse or an interactive video game, navigate a business application, use a web browser, control almost any Windows application, play musical synthesizers, activate peripheral devices, adjust environmental controls, etc. 

Cyberlink Interface is based on a breakthrough technology that senses and responds to the minute surface electrical signals that result from brain and subtle muscle activity. Twelve different biological signals derived from the forehead control the location and left/right functions of the mouse. Individual control formats and adjustments are easily made through the user-friendly graphical interface. 

Three Sensors in the headband detect your brain and facial activity. The Cyberlink interface unit amplifies and translates this data into separate frequencies and transmits them to the IBM compatible PC serial port. The Cyberlink software processes and displays these frequencies as 10 continuous command signals called Brainfingers and up to 4 discrete command signals generated by specific eye and facial gestures.

Cyberlink waves measuring.The Brainfingers control the two-axis mouse cursor, affect visual and musical biofeedback displays, and also can be user-formatted to send mouse button and keyboard commands. The eye movements and facial gestures are separately mapped to a repertoire of user-formatted mouse and keyboard functions and software commands.

Any 95 / 98 / ME / XP application or game can be controlled hands-free with this system using the Cyberlink Actuated Tracker or C.A.T.

Cybergel is applied sparingly to the forehead or sensors when appropriate to moisturize the skin and improve the system’s connection to the user.

The Cyberlink is packaged with several applications and games. Each one was designed to not only be enjoyable, but help to improve your skills as well.


The increasing sophistication of computer programs and communication systems requires the development of more efficient, intuitive and interactive human-computer input interfaces.

The Cyberlink package.Similarly, computer hardware is miniaturizing; becoming less cumbersome and more portable at an incredible rate. What was on your desktop yesterday, is on your laptop or palmtop today and will be on your wrist watch or ring tomorrow…fully integrated with your home PC and the NET.

Imagine having to carry a ‘qwerty’ keyboard and mouse in your briefcase or pocketbook to use with your wrist watch computer and eyeglass monitor! Input devices will have to miniaturize as well and become more direct, intuitive and able to be used while your hands (and part of your attention) are engaged elsewhere.

The Cyberlink System represents this next step in the evolution of the human-computer input interface. The Cyberlink System is a BrainBody actuated control technology that combines eye-movement, facial muscle, and brain wave bio-potentials detected at the user’s forehead to generate computer inputs that can be used for a variety of tasks and recreations.

The forehead is a convenient, non-invasive measuring site rich in a variety of bio-potentials. Signals detected by three plastic sensors in a headband are sent to a Cyberlink interface box which contains a bio-amplifier and signal processor. The interface box connects to the PC computer’s serial port. The forehead signals are amplified, digitized and translated by a patented decoding algorithm into multiple command signals, creating an efficient, intuitive and easily learned hands-free control interface.

Three different types or channels of control signals are derived from the forehead signals by the Cyberlink Interface. The lowest frequency channel is called the ElectroOculoGraphic or EOG signal. This is a frequency region of the forehead bio-potential that is responsive primarily to eye movements. The EOG signal is typically used to detect left and right eye motion. This signal can be mapped to left and right cursor motion or on/off switch control.

The second type of control signal is called the ElectroEncephaloGraphic or EEG signal. The Cyberlink Interface subdivides this region into ten component frequency bands called ‘Brainfingers’. These frequencies reflect internal mental/brainwave activity as well as subtle facial muscle activity. A wide range of facial muscles affect these frequency bands. Users typically learn control of their Brainfingers first through subtle tensing and relaxing of various muscles including forehead, eye and jaw muscles. After a little experience with the Cyberlink System, most users begin to experiment with more efficient, internal brain-based control methods. Since this frequency region is sensitive to both mental and muscular signals it is called the ‘BrainBody’ signal.

Brainfinger control is continuous or analog and is typically used for such things as control of cursor vertical or horizontal movement. For example, one Brainfinger may be used to control vertical movement while a second Brainfinger (or other signal channel) is used to control horizontal movement.

The third channel is called the ElectroMyoGraphic or EMG signal. The EMG signal primarily reflects facial muscle activity. It is typically used in the Cyberlink System for discrete on/off control of program commands, switch closures, keyboard commands, and the functions of the left and right mouse buttons.

In a Cyberlink discrete control study conducted by the United States Air Force at Wright Patterson Air Force Base in Dayton, Ohio, subjects’ reaction times to visual stimuli were found to be 15% faster with the Cyberlink EMG button than with a manual button.

Specific facial and eye movement gestures can be discriminated by the Cyberlink software and mapped to separate mouse, keyboard, and program functions.

Continuous and discrete control capabilities have been incorporated into a WINDOWS mouse driver: the Cyberlink Actuated Tracker, or C.A.T. This hands-free mouse enables the user to steer the cursor, change its speed and resolution, perform left and right mouse button functions, and send keyboard characters and character string commands. The C.A.T. features a selection of user-formatted control paradigms.

In a recent study, users were able to use the C.A.T. to position and click the cursor over randomly appearing 32 x 32 pixel (icon-sized) targets in 4 seconds or less.

The C.A.T. makes hands-free two-axis control possible not only with Cyberlink specific games and applications, but also with third-party software; including popular interactive games, word processors, spread sheets, and Computer-Aided Design programs as well as special-needs software such as Words Plus EZ Keys, WiViK2, Clicker Plus, and GUS. The C.A.T. can be used for hands-free environmental control using an X-10 Home Controller relay for example to switch on and off an electric light, appliance, or communication device.

For individuals with limited control of their facial muscles, the Cyberlink software can be formatted to use BrainBody or EOG inputs (instead of EMG) to activate switch closures and mouse button clicks.

The Cyberlink System provides an intuitive, more direct, hands-free, language-independent control interface. It represents a cutting-edge technological achievement in the user-computer interface making possible new computer control methods to empower the disabled and all users of tomorrow’s technology.
