The Attention meter indicates the intensity of a user’s level of mental “focus” or “attention”. Its value ranges from 0 to 100. Attention level increases when user focuses on a single thought or an external object, decreases when distracted.


The Meditation meter indicates the level of a user’s mental “calmness” or “relaxation”. Its value ranges from 0 to 100. Meditation level increases when user relaxes his/her mind and decreases when he/she is uneasy or stressed.

Blink Detection

The Blink Detection algorithm provides an indication whenever the user blinks. A higher number indicates a “stronger” blink, while a smaller number indicates a “lighter” or “weaker” blink.

Sensor contact on/off

Determines whether a headset is being worn by detecting whether the sensor and reference are contacting a conductive surface, such as skin.

Signal Quality

Indicating the captured brainwave signal quality is good or bad. Based on that users can decide whether the brainwave signal is usable or not.
