NeuroSky Technology Overview
ThinkGear
ThinkGear is the technology inside every NeuroSky product or partner product that
enables a device to interface with the wearers’ mental state. It includes the sensor that
touches the forehead, the contact and reference points located in the ear clip, and the
on-board chip that processes all of the signal received from the body surface. The eSense
Meters (Attention and Meditation) are calculated on the ThinkGear chip.
eSense
eSense(tm) is a NeuroSky's proprietary algorithm for characterizing mental states. To
calculate eSense, the NeuroSky ThinkGear technology amplifies the biosignal and
removes the ambient noise and muscle movement. The 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
The 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 proficiency with
each of the eSense™ meters. In many cases, people tend to be better at one eSense
than the other when they first 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.
