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 es-
tablished in conventional brainwave measurement techniques (though
the method for determining a ThinkGear baseline is proprietary and
may differ from other methods).
A value from 60 to 80 is considered “slightly elevated”, and may be
interpreted as levels tending to be higher than normal (levels of Atten-
tion 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. These levels may
indicate states of distraction, agitation, or abnormality, according to the
opposite of each eSense.
The 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
for the fact that brainwaves in the human brain are subject to normal
ThinkGear sensors are able to operate on a wide range of individuals
under an extremely wide range of personal and environmental condi-
tions, while still giving good accuracy and reliability.
ATTENTION eSense
The 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 anxi-
ety may lower the Attention meter level. See eSense Meter - General
Information for more details about interpreting eSense levels.
MEDITATION eSense
The 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 in-
creasing 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.
