NeuroSky Technology Overview
Brainwaves
e last century of neuroscience research has greatly increased our knowledge about the brain and
particularly, the electrical signals emitted by neurons ring in the brain. e patterns and frequencies
of these electrical signals can be measured by placing a sensor on the scalp. e Mind line of headset
products contain NeuroSky inkGear™ technology, which measures the analog electrical signals,
commonly referred to as brainwaves, and processes them into digital signals to make the measurements
available to games and applications. e table below gives a general synopsis of some of the commonlyrecognized frequencies that tend to be generated by different types of activity in the brain:
Brainwave Type Frequency range Mental states and conditions
Delta 0.1Hz to 3Hz Deep, dreamless sleep, non-REM sleep, unconscious
eta 4Hz to 7Hz Intuitive, creative, recall, fantasy, imaginary, dream
Alpha 8Hz to 12Hz Relaxed, but not drowsy, tranquil, conscious
Low Beta 12Hz to 15Hz Formerly SMR, relaxed yet focused, integrated
Midrange Beta 16Hz to 20Hz inking, aware of self & surroundings
High Beta 21Hz to 30Hz Alertness, agitation
ThinkGear
inkGear is the technology inside every NeuroSky product or partner product that enables a device
to interface with the wearers’ brainwaves. It includes the sensor that touches the forehead, the contact
and reference points located in the ear clip, and the on-board chip that processes all of the data. Both
the raw brainwaves and the eSense Meters (Attention and Meditation) are calculated on the inkGear
chip.
eSense
eSense™ is a NeuroSky's proprietary algorithm for characterizing mental states. To calculate eSense,
the NeuroSky inkGear technology amplies the raw brainwave signal and removes the ambient
noise and muscle movement. e eSense algorithm is then applied to the remaining signal, resulting
in the interpreted eSense meter values. Please note that eSense meter values do not describe an exact
number, but instead describe ranges of activity.

Chapter 2 – NeuroSky Technology Overview
eSense Meter - General Information
e eSense meters are a way to show how effectively the user is engaging Attention (similar to concentration) or Meditation (similar to relaxation).
Like exercising an unfamiliar muscle, it may take some time to gain full prociency with each of the
eSense™ meters. In many cases, people tend to be better at one eSense than the other when they
rst begin. We recommend trying different tactics until you are successful with one. Once you see
a reaction on the screen from your efforts, you will be able to duplicate the action more easily with
additional practice.
Generally, Attention can be controlled through a visual focus. Focus on a singular idea. Try to “funnel”
your concentration and focus your train of thought towards pushing up the meter. Other suggestions
include picking a point on the screen to stare at or imagining the action you are trying to accomplish
happening. For example, look at the Attention eSense meter and imagine the dial moving towards
higher numbers.
For Meditation, it typically helps to try to relax yourself. Connect to a sense of peace and calm by
clearing your mind of thoughts and distractions. If you are having difficulty engaging Meditation, close
your eyes, wait a number of seconds, and then open your eyes to see how the meter has responded.
If you have trouble at rst in controlling your eSense meter levels, be patient. Try different techniques
and practice. Also be sure to read and try to understand the Technical Description in order to get a
better idea about how eSense actually works under the hood.
eSense Meter - Technical Description
For each different type of eSense (i.e. Attention, Meditation), the meter value is reported on a relative
eSense scale of 1 to 100. On this scale, a value between 40 to 60 at any given moment in time is considered “neutral” and is similar in notion to “baselines” that are established in conventional brainwave
measurement techniques (though the method for determining a inkGear baseline is proprietary and
may differ from conventional brainwaves).
A value from 60 to 80 is considered “slightly elevated”, and may be interpreted as levels tending to
be higher than normal (levels of Attention or Meditation that may be higher than normal for a given
person). Values from 80 to 100 are considered “elevated”, meaning they are strongly indicative of
heightened levels of that eSense.
Similarly, on the other end of the scale, a value between 20 to 40 indicates “reduced” levels of the
eSense, while a value between 1 to 20 indicates “strongly lowered” levels of the eSense. ese levels
may indicate states of distraction, agitation, or abnormality, according to the opposite of each eSense.
e reason for the somewhat wide ranges for each interpretation is that some parts of the eSense
algorithm are dynamically learning and at times employ some “slow-adaptive” algorithms to adjust
to natural uctuations and trends of each user, accounting for and compensating for the fact that
brainwaves in the human brain are subject to normal ranges of variance and uctuation. is is part
of the reason why inkGear sensors are able to operate on a wide range of individuals under an
extremely wide range of personal and environmental conditions, while still giving good accuracy and
reliability.

Chapter 2 – NeuroSky Technology Overview
ATTENTION eSense
e eSense Attention meter indicates the intensity of a user's level of mental “focus” or “attention”,
such as that which occurs during intense concentration and directed (but stable) mental activity. Its
value ranges from 0 to 100. Distractions, wandering thoughts, lack of focus, or anxiety may lower the
Attention meter level. See eSense Meter - General Information for details about interpreting eSense
levels in general.
MEDITATION eSense
e eSense Meditation meter indicates the level of a user's mental “calmness” or “relaxation”. Its value
ranges from 0 to 100. Note that Meditation is a measure of a person's mental states, not physical levels,
so simply relaxing all the muscles of the body may not immediately result in a heightened Meditation
level. However, for most people in most normal circumstances, relaxing the body often helps the mind
to relax as well. Meditation is related to reduced activity by the active mental processes in the brain.
It has long been an observed effect that closing one's eyes turns off the mental activities which process
images from the eyes. So closing the eyes is often an effective method for increasing the Meditation
meter level. Distractions, wandering thoughts, anxiety, agitation, and sensory stimuli may lower the
Meditation meter levels. See eSense Meter - General Information for details about interpreting eSense
levels in general.

Troubleshooting and Support
e MindWave does not turn on.
e battery might be low. Please try replacing the battery and try again.
I am having issues with my wireless RF connection.
Please use the RF Dongle included with the MindWave, and then be sure to carefully follow the
instructions under Setting Up Your MindSet, paying particular attention to RF Dongle Setup, RF Mind-
Wave Pairing, and Serial Port Name. en please check if your issue has been addressed in the RF
Connection Troubleshooting section.
Also if you have a desktop computer, please use a usb extension cable to pull the RF dongle to a visible
location.
e signal quality status is consistently poor (fewer than three bars).
Check that the forehead sensor and each clip contacts are making good contact with the skin. Make
sure to remove all obstructions including hair and jewelry.
It usually takes three or four seconds for the headset to validate the signal after holding still. Also make
certain to keep the sensor and contacts clean.
e eSense meters do not move.
Verify that the RF is paired correctly. You can use the Brainwave Visualizer to verify if the headset is
transmitting. Select "Show data output" from the menu. If the numbers are changing, that means the
headset is transmitting data to the PC.
Allow the eSense meters to go through a few moments to go through initialization before troubleshooting. If the meters do not move after 10 seconds, make sure the sensor rests on the forehead and the
contacts are on the left ear. e sensor and contacts should make rm and consistent contact with
your skin.
I don't seem to be able to control the eSense™ meters.
Like exercising an unfamiliar muscle, it may take some time to gain full prociency with the eSense™
meters. First, be sure you understand how the eSense meters work and what they are measuring.
Generally, we recommend engaging Attention by concentrating and Meditation by relaxing. Most
importantly, be sure you have read the detailed explanation of eSense previously described in the
eSense™ sections.
I still have a problem, or my problem is not covered by this Troubleshooting section.
