EEG Headsets: The New Way OF Neuro-Tracking

Dec 27, 2022by, Pooja Ramesh


A monitoring technique to capture the electrical activity in the brain is electroencephalography (EEG). Non-invasive electrodes are positioned along the scalp by wearable EEG headsets. The medical term for EEG is the long-term recording of brain activity. The electrical impulse in your brain is detected by and recorded by EEG electrodes. The signals are generated and converted to digital form before being delivered to a pc or smartphone for data processing and storage.

What is an EEG Headset?

A piece of wearable equipment for electroencephalography and tracking techniques to record brain waves, is an EEG headset. In order to monitor brain activity, EEG sensors in headsets attach electrodes along the scalp. The investigation of cognitive processes is aided by EEG analysis. EEG is a tool that doctors can use to diagnose patients. This approach can help researchers better understand how the brain works. By tracking their moods and emotions, people can use EEG to increase their productivity and wellness. To carry out direct mind instructions in application development and a variety of different use cases, developers can employ EEG for BCI.

How do EEG Headsets Work?

Electrodes arranged in an array around the scalp of the user or research subject are used by electroencephalography (EEG) headsets to detect brain activity. EEG headsets come in a few different varieties. Wet electrode arrays and dry electrode EEG headsets are frequently compared. A sticky gel, saline solution, or other substance is used by wet electrodes to enhance signal quality. By doing this, the EEG gadget is guaranteed to record accurate data. The conducting gel is typically not needed because the majority of dry EEG headsets produce accurate readings, whether elevated data is needed for certain diagnostic research or high precision.

What are EEG Headsets Used For?

EEG headsets are employed in medical research, the study of mental states, and the diagnosis of a few medical problems, including epileptic and sleep disorders. Brain-computer interactions can also be performed with EEG headsets. Portable EEG headsets are ones that transmit data collected wirelessly to a computer. In real-world settings outside of a lab or in research labs looking to increase the series of research subjects, this movable EEG headset type is ideal. In computer-brain interfaces like EEG headset gaming, it is also employed. Neurofeedback is used in EEG ADHD training programs to “work out” the brain. While playing video games created specifically to improve cognitive abilities or control physical objects, participants wear an EEG VR headset.

Types Of EEG Headsets

  • Commercial EEG Headsets: Commercial electroencephalography (EEG) headsets are made for commercial applications like consumer data or anxiety monitoring in the field and are utilised in the visual cortex interface and research. Researchers interested in conducting studies outside of a lab, such as in the workplace, can benefit from mobile EEG headgear.
  • Open Source EEG Headsets: Joel Murphy and Conor Russomanno created the open-source OpenBCI brain-computer interface platform in 2013. They also made design files available for something like an open-source headset dubbed the Ultracortex and an OpenBCI software application. Some EEG headsets connected to the OpenBCI program can be categorized as open source.

What is the Best EEG Headset?

Data collection with electroencephalography (EEG) is a challenging process. Leading EEG headsets on the market have the following features:

  • Multiple (5 or more) channels of EEG sensing, provided by that number of electrodes in the array
  • Easy-to-understand user experience and setup
  • Wirelessly connects to PC and/or mobile devices
  • Rechargeable battery with 9 or more hours of battery life
  • High sensitivity (0.5uV or better minimum resolution) and adequate sample frequency per channel (100Hz or higher)
  • Low noise and high rejection of background body potential signals

How are EEG Headsets Used for Research?

The sensitive technique of electroencephalography (EEG) can record brain activity. Research-grade data collection can be hampered by artefacts or signals that are not produced by the brain. Any EEG equipment can record these artefacts, therefore depending on the goals of the researcher, an inexpensive EEG headset may well be adequate. Artefacts can either be participant-induced, like muscle and eye movements or experimental, like electromagnetic interference and electrode displacement. Any of the other non-brain impulses have the potential to impede the gathering and quality of data. Because of this, scientists tend to favour EEG devices that capture brain data with the fewest artefacts possible.

EEG Headsets for Gaming

Video games can be controlled via electromyography and electroencephalography (EEG). It is possible to program gaming software to distinguish frequent thought patterns and the brain function shown on an EEG. The narrative of the game can be crafted to include moods and emotions like boredom, excitement, and aggravation in order to provide the intended user experience. Gaming headsets are taught by repetitive patterns of thought and commands assigned to those patterns. There is no need for particular user training for these detections. These sequences can then be utilized to control avatars in video games or even other in-game actions after this procedure is finished.

EEG devices are rapidly declining in cost and expanding in availability, which should enable more commercial and private usage of the data. Due to their ubiquitous availability, numerous factors should be taken into account before choosing to buy and use a gadget. The battery capacity of an EEG device, relevant data processing software, and typical usage of the equipment in research fields, particularly where your own research may apply, are additional considerations in addition to the price.
