Emotiv System's products are the Emotiv EPOC, a peripheral for gaming on Windows PCs, and the Emotiv EEG neuroheadset.
Emotiv Systems claims the headset will make it possible for games to be controlled and influenced by the player's mind, and facial expressions. It connects wirelessly with the PC, and may in the future work on other game platforms such as consoles. The Epoc was designed by a Emotiv Systems in conjunction with the Sydney based Industrial Design consultancy 4design. For compatibility with non-compliant software EmoKey would be provided in order to bind commands to keys or combinations thereof transforming the device into an HID. Software Development Kitsare also available.
Based on the latest developments in neuro-technology, Emotiv presents a revolutionary personal interface for human computer interaction. Emotiv EPOC is a high resolution, multi-channel, wireless neuroheadset. The EPOC uses a set of 14 sensors plus 2 references to tune into electric signals produced by the brain to detect the user’s thoughts, feelings and expressions in real time. The EPOC connects wirelessly to PCs running Windows, Linux, or MAC OS X.
Experience the fantasy of controlling and influencing the virtual environment with your mind. Access applications and play games developed specifically for the EPOC, or use the EmoKey to connect to current PC games and experience them in a completely new way.
Please note: If you or any of your 3rd party applications require access to raw EEG data, you will need to purchase the Emotiv EEG Neuroheadset.

The detection suites that are incorporated into the Emotiv EPOC are:
The Expressiv suite uses the signals measured by the neuroheadset to interpret player facial expressions in real-time. It provides a natural enhancement to game interaction by allowing game 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.
The Affectiv suite monitors player emotional states in real-time. It provides an extra dimension in game interaction by allowing the game 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 experience for the user in real-time. The Affectiv suite can be used to monitor user state of mind and allow developers to adjust difficulty to suit each situation.
The Cognitiv suite reads and interprets a user's conscious thoughts and intent. Users can manipulate virtual objects with only the power of their thought! For the first time, the fantasy of magic and supernatural power can be experienced.
The limited edition EPOC is available World Wide. Users will have access to the Emotiv App Store and innovative apps and games developed exclusively for EPOC.
Developers are currently utilizing Emotiv EPOC technology in a variety of new and exciting ways:
Artistic and creative expression
Use your thoughts, feeling, and emotion to dynamically create color, music, and art. Life changing applications for disabled patients, such as controlling an electric wheelchair, mind-keyboard, or playing a hands-free game.
Games & Virtual Worlds
Experience the fantasy of controlling and influencing the virtual environment with your mind. Play games developed specifically for the EPOC, or use the EmoKey to connect to current PC games and experience them in a completely new way.

Windows Requirements• 2.4 GHz Intel Pentium 4 processor (or equivalent)
• Microsoft Windows XP with Service Pack 2, Windows Vista or Windows 7
• 1GB RAM. • 50MB available disk space
• USB 2.0 ports (depending on the number of neuroheadsets you wish to use simultaneously
Mac Requirements• MAC OS X ( 10.5.x, 10.6.x, 10.7.x )
• Intel-based Macintosh
• Hard disk with 500Mb available.
The EPOC has 14 electrodes (compared to the 19 electrodes of a standard medical EEG, and the 3 of OCZ's NIA features and a multiple of NeuroSky's single electrode). It also has a two-axis gyro for detecting head movements.
- Conscious thoughts (Cognitiv suite): The device detects 13 kinds of movement - six directions (left, right, up, down, forward, and "pull/zoom") and six rotations ([anti-]clockwise rotation, turn left and right, and sway backward and forward), plus one other visualization ("disappear"). While the current driver may only be able to listen for any 4 of these at a time, the degrees of freedom are larger than a joystick's 2 df. Ideomotor responses or the much stronger EMG currents aside, these thought Because of the complex detection algorithms involved, there is a slight lag in detecting thoughts. However, the technology may still be useful in a support role like calling up a minimap or radar in a FPS game.
- Emotions (Affectiv suite): "Excitement", "Engagement/Boredom", "Meditation", and "Frustration" can currently be measured. Emotiv admits that the names may not perfectly reflect exactly what the emotion is, and says that they may be renamed before market launch.
- Facial expressions (Expressiv suite): Individual eyelid and eyebrow positions, eye position in the horizontal plane, smiling, laughing, clenching, and smirking can currently be detected. Other expressions may be added prior to release. The expressions are detected by the EEG sensors picking up signals to facial muscles, rather than by reading brainwaves. Unlike reading mental activity, these detections are very fast (10ms) conveying a decisive advantage and rendering them suitable for fast paced games in the FPS genre.
- Head rotation: The angular velocity of one's head can be measured in the yaw and pitch (but not roll) directions. This is detected by gyros, and isn't related to the EEG features.
Potential for EEG Research
The EEG neuroheadset provides access to raw electroencephalography data. The EPOC brain helmet has eighteen sockets and can hold sixteen nodes or sensor pads. The remaining two sockets usually hold rubber pads, and are known as the secondary reference sensors, which are located immediately below and behind the ears. The primary reference sensors, which generally hold a normal sensor pad, are located immediately above and behind the ears. The sensors pads detect electrical activity on the surface of the brain.
The EPOC also includes "EmoKey" software used to emulate keystrokes based on combinations of thoughts, feelings, and facial expressions. Any EPOC detection can be paired with keystrokes or string of keystrokes through a simple user interface by the end user. Future versions will also emulate the mouse based on the gyros. This software allows most existing games, instant messaging programs, and other software to be controlled with the headset.The Emotiv EPOC ships with a demo game called "Spirit Mountain, built on the Unity3D. Videos of portions of the game have been shown at conferences and in media interviews. The game involves a first person view of the user walking around a virtual environment, with many different activities at different locations. The sky changes color according to the mood of the player. Demonstrated activities in the game include pushing and rotating giant stone structures into the shape of stone henge, then raising a temple from below the ground; levitating a large rock and some smaller ones; repairing a bridge; bending a tree; and scaring away glowing spirits with scary facial expressions.
There is also a planned web site known as "Emortal", for listening to music, viewing photos, and other activities, modified based on what the user is thinking and feeling.
Another product is the Emotiv Control Panel, also seen in many videos, which allows users to train the various thoughts, such as "push" and "disappear", and test them on a floating, bobbing, cube. It also allows users to view their emotional state, such as "excitement", on a graph. It has a 2D blue avatar that allows the user to view their own facial expressions, and adjust the sensitivity of those detections.
The company provides several software development kits, which includes a headset, applications and libraries used for interfacing with the headset, with varying limitations and pricing.
A free of charge SDK (called SDK Lite) is also available for download from the Emotiv website.It includes software to emulate the Emotiv EPOC output for developers who do not have one of the headsets.
The SDKs currently support Microsoft Windows, Ubuntu Linux, Fedora Linux, and Mac OS X
Emokit is an open-source and cross-platform Python and C library for reading out sensor data from the EPOC by Cody Brocious. It was built by reverse-engineering the encrypted protocol.
