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 MindSet contains 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 commonly-recognized 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 on the ear pad, 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 amplies 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.

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 prociency 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.

Using Your MindSet

is chapter walks you through tting the MindSet and installation of the included MindSet software on your PC or Mac.

Fitting the MindSet

e MindSet is more than your average headset. It has the ability to use your brainwaves for exciting new applications.
Important: In order to take full advantage of these functions and features of the MindSet, the MindSet must be properly worn.
1. e sides of the Mindset are adjustable and can be extended to t various sizes. e Forehead Sensor Arm is exible and should arch inwards. Extend the sides as necessary and bend the Forehead Sensor Arm to comfortably t your head.
2. Orient the MindSet with the Forehead Sensor Arm on your left hand side. Put on the MindSet. If the sensor does not make contact with the forehead or if the t is not comfortable, remove the MindSet to readjust the sides and the Forehead Sensor Arm.
Figure 4.1: Orient the MindSet correctly before wearing it
3. Make sure the contact points on the left ear pad make skin-contact with your ear. Move any hair or obstructions out of the way. Readjust the left ear cup as necessary to make proper contact with your ear.

To nd new and exciting ways to unlock the full potential of you MindSet, visit the NeuroSky Store for additional software and applications: http://store.neurosky.com
e MindKit is a bundle that allows developers and researchers to use or create applications to interface with the MindSet. e MindKit can output both raw brainwaves and the eSense signals, and allows for recording and analysis. is information can be used to conduct research or to develop applications, games, or demonstrations. e MindKit consists of a MindSet plus the MindSet Development Tools (MDT).

MindSet Development Tools (MDT)

e NeuroSky MindSet Development Tools (MDT) provides the tools and resources necessary to create and publish games and applications capable of taking advantage of the exciting new Brain­Computer Interface (BCI) technology of NeuroSky’s MindSet headset. e MindSet Development Tools includes drivers, sample code, and documentation describing how to develop applications for several software platforms, including PC, Symbian, and even lower level platforms such as microcon­trollers like the Arduino™.
Languages directly supported include C/C++, C#, Java (through JNI), and J2ME. Create exciting new games that challenge people to use the power of their mind or retrot your existing games with a new dimension of brainwave control. NeuroSky’s MDT also includes tools and applications that will allow you to research and understand the behaviors of brainwaves at a low level, giving you the potential to develop your own brainwave-based algorithms. Lastly, the MDT provides the ability to publish your nished applications at the NeuroSky Store.

Troubleshooting

e MindSet does not turn on.
e MindSet's charge might be low. Please recharge the MindSet. When charging the MindSet, make sure that the mini USB is plugged in all of the way.
I am having issues with my Bluetooth connection.
Please use the Bluetooth Dongle included with the MindSet, and then be sure to carefully follow the instructions under Setting Up Your MindSet, paying particular attention to Bluetooth Dongle Setup, Bluetooth MindSet Pairing, and Serial Port Name. en please check if your issue has been addressed in the Bluetooth Troubleshooting section.
Audio does not work.
1. Verify that the MindSet Bluetooth Audio is connected to the PC.
(a) Go to the menu that displays all of the Bluetooth connections.
(b) Find "MindSet" and verify the Bluetooth Audio is connected.
2. Verify that the audio is set to output to Bluetooth Audio
(a) Go to the Control Panel and select "Audio."
(b) Set the default playback device in the Sound Control Panel to "Bluetooth Audio."
(c) Restart the media player or other audio application after changing the settings.
If the audio still does not work, try to un-pair and re-pair the MindSet.
e signal quality status is consistently poor (fewer than three bars).
e ear contacts should be resting directly on your ear and the forehead sensor should be on your forehead. Also, check that the sensors and 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 Bluetooth 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 prociency 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
