EMOTIV EPOC
BCI & Practical EEG Research
The Emotiv EPOC is a high resolution, multi-channel, portable system
which has been designed for practical research applications.
License our Testbench™ software to receive raw EEG data from the
Neuroheadset and our proprietary software toolkit that exposes our APIs
and detection libraries: Mental Commands, Performance Metrics &
Emotional States and Facial Expressions.
Performance Metrics & Emotional
States
This suite monitors the user’s
emotional states in real-time. It
enables an extra dimension in
interaction by allowing the computer
to respond to a user's emotions.
Characters can transform in response
to the user's feeling. Music, scene
lighting and effects can be tailored to
heighten the user’s experience in realtime. The user’s state of mind can be
monitored so that difficulty can be
tailored and adjusted to suit each
situation.
The suite can be combined with other
inputs such as eye tracking devices to
provide real-time feedback from the
entire user experience for
neuromarketing applications.
Adaptive interfaces can monitor user
engagement, boredom, excitement,
frustration and meditation level in
real time.
Facial Expressions
Mental Commands
This uses the signals measured by the
Emotiv EPOC to interpret player facial
expressions in real-time. It provides a
natural enhancement to interaction
by allowing characters to come to life.
When a user smiles, their avatar can
mimic the expression even before
they are aware of their own feelings.
Artificial intelligence can now
respond to users naturally, in
ways only humans have
been able to until now.
This detection suite reads and
interprets a user's conscious thoughts
and intent. Users can manipulate
virtual or real objects using only the
power of their thought! For the first
time, the fantasy of magic and
supernatural power can be
experienced.

TestBenchTM
Real-time display of the Emotiv headset data stream, including EEG, contact quality, FFT, gyro (if fitted – custom
option), wireless packet acquisition/loss display, marker events, headset battery level.
!
Record and replay files in binary EEGLAB format. Command line file converter included to produce .csv format.
!
Define and insert timed markers into the data stream, including on-screen buttons and defined serial port events.
Markers are stored in EEG data file. Marker definitions can be saved and reloaded. Markers are displayed in real time
and playback modes.
EEG display:
- 5 second rolling time window (chart recorder mode)
- ALL or selected channels can be displayed
- Automatic or manual scaling (individual channel display mode)
- Adjustable channel offset (multi-channel display mode)
- Synchronized marker window
