# Electroencephalography (EEG) Technology Applications and Available Devices
## 4 EEG Headset Applications and Research Usages  
There are many commercially available EEG headsets. In the following, a set of tables shows the approximate applications for each headset, as well as their specifications and relative research use. In general, information was gathered from the company website for each product. Table 1 indicates the applications that each EEG Headset has been used in, according to the producing company's reports. \begin{table}
\begin{tabular}{c c l} \hline \hline
**Applications (Company Recommendation)** & **EEG Headset Product Name (Company)** \\ \hline Neuroscience Research & \(\bullet\) & DSI 24, DSI 7, DSI 7 Flex, VR300 (Wearable Sensing) \\ Neuroscience Research & \(\bullet\) & B-Alert X-Series (Advanced Brain Monitoring) \\  & \(\bullet\) & Enobio (Neuroelectrics) \\  & \(\bullet\) & Eego mylab (ANT Neuro) \\  & \(\bullet\) & Imec product \\  & \(\bullet\) & SMARTFONES, SMARTING (mBrainTrain) \\ \hline Neuromarketing & \(\bullet\) & DSI 24, DSI 7 (Wearable Sensing) \\  & \(\bullet\) & B-Alert X-Series (Advanced Brain Monitoring) \\  & \(\bullet\) & SMARTFONES, SMARTING (mBrainTrain) \\ \hline Brain computer interface and Neurogaming & \(\bullet\) & DSI 24, DSI 7, VR300, NeuroCube, NeusenW (Wearable Sensing) \\ Brain computer interface and Neurogaming & \(\bullet\) & Epoc \({}^{\times}\), Epoc \({}^{\text{Flex}}\), INSIGHT (Emotiv) \\  & \(\bullet\) & B-Alert X-Series (Advanced Brain Monitoring) \\  & \(\bullet\) & Enobio (Neuroelectrics) \\  & \(\bullet\) & MindWave, MindWave Mobile 2 (NeuroSky) \\  & \(\bullet\) & BrainWaveBank products \\  & \(\bullet\) & NeusenW (wearable sensing) \\  & \(\bullet\) & Eego mylab, Eego\({}^{\text{TM}}\) mini-series (ANT Neuro) \\  & \(\bullet\) & SMARTFONES, SMARTING (mBrainTrain) \\ \hline \hline \end{tabular}

Table 1: Recommended EEG application by manufactured company. Figure 4: Percentage of each topic found through internet keyword search. Table 2 provides information about the characteristics of the available EEG headsets\(\backslash\)caps, such as number of channels, sampling rate, electrode connection type, headset preparation time (the amount of time it takes to prepare the headset/cap), and price. Some of the EEG devices are equipped with extra sensors, enabling them to track muscle activities (EMG), heart rate (ECG), eye movement (EOG), and blood pressure (PPG); these are indicated in the \"Extra Sensors\" column. The \"Motion Sensors\" column shows any EEG devices that have motion sensors, such as an accelerometer or gyroscope, for tracking body or head movement. The \"Communication Mode\" column indicates the way in which the sensor transfers its recorded data. If the EEG device is a wireless Bluetooth device, it works in a specific range, and outside of that distance, may not work correctly; this information is shown in the \"Bluetooth range\" column. The \"Battery life\" column shows how many hours the device is capable of working for using its wireless technology. For some companies, such as Compumedics Neuroscan, the listed EEG devices are only components of the full device, which is necessary to perform Electroencephalography, such as cap and amplifier, thus cannot be used without the purchase of separate hardware. Some of the EEG devices have included open source software, allowing users to capture and analyze the data for free, while for some headset/caps, users need to pay subscription fees and/or purchase the related software; this information is denoted in the \"Included Software\" column.
