What are the challenges in EEG monitoring and analysis?

A small SNR and different noise sources are amongst the greatest challenges in EEG-based BCI application studies. Unwanted signals contained in the main signal can be termed noise, artifacts, or interference. There are two sources of EEG artifacts: external or environmental source and physiological source.

What are the benefits of BCI?

BCI can be used as an assistive, adaptive, and rehabilitative technology to monitor the brain activity and translate specific signal features that reflect the elderly’s intent into commands that operate any device.

What are the advantages of brain computer interface?

Following are the benefits or advantages of Brain Computer Interface: ➨It allows paralyzed people to control the prosthetic limbs with their mind. ➨Transmit visual images to the mind of a blind person which allows them to see. ➨Transmit auditory data to the mind of a deaf person which allows them to hear.

What is EEG BCI?

Non-invasive electroencephalogram (EEG)-based brain-computer interfaces (BCI) can be characterized by the technique used to measure brain activity and by the way that different brain signals are translated into commands that control an effector (e.g., controlling a computer cursor for word processing and accessing the …

What are the challenges of brain-computer interface (BCI)?

The intrinsic neurophysiological instability of brain dynamics poses critical challenges for making BCI systems efficient. The major components of a BCI system are signal acquisition, signal processing and effector device (Schwartz et al., 2006).

What are the major components of a brain-computer interface system?

The intrinsic neurophysiological instability of brain dynamics poses critical challenges for making BCI systems efficient. The major components of a BCI system are signal acquisition, signal processing and effector device ( Schwartz et al., 2006 ).

Are brain-computer interfaces the next trend?

Brain-Computer Interfaces are poised to become the next trendy consumer device. As such, most consumer electronics companies have started to integrate them into their roadmap in some way or another. Some companies have already developed and released consumer wireless EEG-based BCI with interesting non-medical applications.

What are the challenges of non-invasive wireless BCIs?

One of the main challenges for non-invasive wireless BCIs is to provide value for many different user populations. One solution could be to integrate BCIs into the microcosm of the user’s devices (smart home) by providing mobile APIs and Bluetooth connectivity.
