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.
Brainwave Visualizer
e Brainwave Visualizer is a colorful, interactive application controlled by your brain that shows you
a graphical representation of your brain’s activity. e Brainwave Visualizer includes the Brainwave
Visualization, Brainwave Power Spectrum Graph, and the eSense Attention and Meditation meters.
e on-screen shapes morph and change color depending on your state of mind. Please refer to the
included Brainwave Visualizer Manual for more details.
