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 eSenseMeters (Attention andMeditation) 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 ampliëes 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. December 4, 2009 | © 2009 NeuroSky, Inc. All Rights Reserved. 6 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 con- centration) or Meditation (similar to relaxation). Like exercising an unfamiliar muscle, it may take some time to gain full proëciency with each of the eSense™ meters. In many cases, people tend to be better at one eSense than the other when they ërst 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 yourmind of thoughts and distractions. If you are having difficulty engagingMeditation, 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 ërst 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 con- sidered “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 ìuctuations 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 ìuctuation. 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. eSense Meter - General Information December 4, 2009 | © 2009 NeuroSky, Inc. All Rights Reserved. 7 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 thatMeditation 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. eSense Meter - Technical Description December 4, 2009 | © 2009 NeuroSky, Inc.
