The headband uses carbon nanofiber-based sensors to provide the highest possible dynamic range for the recording of bioelectrical signals that are amplified and digitized and further de-convoluted into computer commands.

Where others have to practice reaction times, you can use reflex-based game play to get the better of your opponents by cutting your reaction time by 50%

Streaming biopotentials into the computer and witnessing real-time feedback through the game will result in a novel way to experience virtual reality. Enter a virtual world where abstractions like keyboard commands are replaced by intentions converted into tensions and translated into command structures

The Neural Impulse Actuator is truly the way to becoming your virtual character in the game!

The Neural Impulse Actuator is a novel approach to interacting with a computer using biosignals, specifically, electrical potentials recorded from the user's forehead. These electrical potentials are registered by the centerpiece of the NIA, the headband, which features 3 sensors. The biopotentials include electro-myogram, electro-encephalogram, and electro-oculogram, that is electrical signals that are generated by activity patterns in muscles, brain, and eyes respectively. The mass potentials are amplified and de-convoluted into different frequency components to allow assignment of different commands to different channels.

Playing computer games with the NIA as opposed to standard keyboard is different, meaning that the user needs to forget some of the learned habits and to aquire a different set of skills in order to interface with the computer. The NIA takes just a few steps to configure, and gamers can be litterally up and running in their favorite game in a matter of minutes. Just like there is a conventional memory and muscle memory. The user will also develop NIA memory and within a short period of time, the body will remember the reactions it underwent to achieve the desired actions on the computer.

The underlying principle of operation is to present the user with a variety of behavioral choices and to let the user adapt to the requirements in each scenerio. In the begining, most users will primarily use muscle signals, however, within a short period of time, these muscle signals will become auxillary and more subtle signals will take over. Those signals are primarily levels of excitement that cause release of adrenaline by the sympathetic nervous system and acetylcholine by the parasympathetic components of the autonomous nervous system. Among those responses are facial and ocular reflexes like the eye-lid reflex (one of the fastest reflexes in the body that can be used for shooting), and the pupil reflex. Reflexes are also mirrored in the governance of facial blood flow, i.e. the contraction or relaxation of the smooth muscles of the blood vessels that contribute to the electrical signals. All of these signals are being picked up and with increasing experience, voluntary responses will become more and more subordinate and will be replaced by subconscious or unconscious, reflex-based actions.

The nia features an intuitive GUI to allow the user to calibrate signals and coordinate and assign commands.

In general, two types of commands are possible, namely so-called “switch-events” and “joysticks”. Switch events are all or nothing responses that are triggered once the signal amplitude exceeds a certain threshold and are comparable to a digital mode of operation. Joysticks are graded responses on a predefined scale, where “zones” of signal strength can be defined. In addition to vertical joysticks that reflect levels of activity, a horizontal joystick based on lateral eye movements can be used. Both switch events and joystick zones can be arbitrarily bound to keyboard keys or mouse buttons as they are defined in any game’s “options”.

The intuition of the computer behavior is the most important thing to consider when creating a profile for a specific game. However, it is in the interest of any nia user to try anything that comes to mind and to promulgate any profiles that work. It is also necessary to be aware that the capabilities of the nia are different from those of a keyboard, and consequently, the strategies in game play will have to be adjusted in order to take advantage of the shorter reaction times and the higher level of immersion inside the game. For example, the nia will work best in very crowded combat scenes in FPS games where it’s necessary to shoot the enemy with the blink of an eye, whereas mileage in slow game sequences will vary. Also, the nia can be used as a complementary interface with the computer in combination with any other input device. For example in games like World of Warcraft, the 4 or 5 most common keys can be bound to the nia, and the other keys are then entered via keyboard.
