Chapter 2NeuroSky Technology OverviewBrainwavese last century of neuroscience research has greatly increased our knowledge about the brain andparticularly, the electrical signals emitted by neurons ring in the brain. e patterns and frequenciesof these electrical signals can be measured by placing a sensor on the scalp. e MindSet containsNeuroSky inkGear™ technology, which measures the analog electrical signals, commonly referred toas brainwaves, and processes them into digital signals to make the measurements available to games andapplications. e table below gives a general synopsis of some of the commonly-recognized frequenciesthat tend to be generated by different types of activity in the brain:Brainwave Type Frequency range Mental states and conditionsDelta 0.1Hz to 3Hz Deep, dreamless sleep, non-REM sleep, unconsciouseta 4Hz to 7Hz Intuitive, creative, recall, fantasy, imaginary, dreamAlpha 8Hz to 12Hz Relaxed, but not drowsy, tranquil, consciousLow Beta 12Hz to 15Hz Formerly SMR, relaxed yet focused, integratedMidrange Beta 16Hz to 20Hz inking, aware of self & surroundingsHigh Beta 21Hz to 30Hz Alertness, agitationThinkGearinkGear is the technology inside every NeuroSky product or partner product that enables a deviceto interface with the wearers’ brainwaves. It includes the sensor that touches the forehead, the contactand reference points located on the ear pad, and the on-board chip that processes all of the data. Boththe raw brainwaves and the eSense Meters (Attention and Meditation) are calculated on the inkGearchip.eSenseeSense™ 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 ambientnoise and muscle movement. e eSense algorithm is then applied to the remaining signal, resultingin the interpreted eSense meter values. Please note that eSense meter values do not describe an exactnumber, but instead describe ranges of activity.June 10, 2009 | © 2009 NeuroSky, Inc. All Rights Reserved.5
Chapter 2 – NeuroSky Technology OvervieweSense Meter - General Informatione eSense meters are a way to show how effectively the user is engaging Attention (similar to con-centration) or Meditation (similar to relaxation).Like exercising an unfamiliar muscle, it may take some time to gain full prociency with each of theeSense™ 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 seea reaction on the screen from your efforts, you will be able to duplicate the action more easily withadditional 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 suggestionsinclude picking a point on the screen to stare at or imagining the action you are trying to accomplishhappening. For example, look at the Attention eSense meter and imagine the dial moving towardshigher numbers.For Meditation, it typically helps to try to relax yourself. Connect to a sense of peace and calm byclearing your mind of thoughts and distractions. If you are having difficulty engaging Meditation, closeyour 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 techniquesand practice. Also be sure to read and try to understand the Technical Description in order to get abetter idea about how eSense actually works under the hood.eSense Meter - Technical DescriptionFor each different type of eSense (i.e. Attention, Meditation), the meter value is reported on a relativeeSense scale of 1 to 100. On this scale, a value between 40 to 60 at any given moment in time is con-sidered “neutral” and is similar in notion to “baselines” that are established in conventional brainwavemeasurement techniques (though the method for determining a inkGear baseline is proprietary andmay differ from conventional brainwaves).A value from 60 to 80 is considered “slightly elevated”, and may be interpreted as levels tending tobe higher than normal (levels of Attention or Meditation that may be higher than normal for a givenperson). Values from 80 to 100 are considered “elevated”, meaning they are strongly indicative ofheightened levels of that eSense.Similarly, on the other end of the scale, a value between 20 to 40 indicates “reduced” levels of theeSense, while a value between 1 to 20 indicates “strongly lowered” levels of the eSense. ese levelsmay 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 eSensealgorithm are dynamically learning and at times employ some “slow-adaptive” algorithms to adjustto natural uctuations and trends of each user, accounting for and compensating for the fact thatbrainwaves in the human brain are subject to normal ranges of variance and uctuation. is is partof the reason why inkGear sensors are able to operate on a wide range of individuals under anextremely wide range of personal and environmental conditions, while still giving good accuracy andreliability.eSense Meter - General InformationJune 10, 2009 | © 2009 NeuroSky, Inc.

Chapter 2 – NeuroSky Technology OverviewATTENTION 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. Itsvalue ranges from 0 to 100. Distractions, wandering thoughts, lack of focus, or anxiety may lower theAttention meter level. See eSense Meter - General Information for details about interpreting eSenselevels in general.MEDITATION eSensee eSense Meditation meter indicates the level of a user's mental “calmness” or “relaxation”. Its valueranges 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 Meditationlevel. However, for most people in most normal circumstances, relaxing the body often helps the mindto 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 processimages from the eyes. So closing the eyes is often an effective method for increasing the Meditationmeter level. Distractions, wandering thoughts, anxiety, agitation, and sensory stimuli may lower theMeditation meter levels.

Chapter 7Troubleshootinge MindSet does not turn on.e MindSet's charge might be low. Please recharge the MindSet. When charging the MindSet, makesure 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 theinstructions 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 addressedin 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 yourforehead. Also, check that the sensors and contacts are making good contact with the skin. Make sureto 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 makecertain 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 headsetis transmitting. Select "Show data output" from the menu. If the numbers are changing, that meansthe headset is transmitting data to the PC.Allow the eSense meters to go through a few moments to go through initialization before troubleshoot-ing. If the meters do not move after 10 seconds, make sure the sensor rests on the forehead and thecontacts are on the left ear. e sensor and contacts should make rm and consistent contact withyour 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.
