Brain Computer Interface (BCI) Technology

Brain Computer Interface (BCI) is a direct interface or communication path between human brain and computers. In BCI technology, it is possible for machines to interact immediately with the cognitive state of human brain, measure its activity signals using electrical electrodes in most cases, and interpret these signals for controlling external devices [1].

Depending on how close electrodes get to brain tissue, there are three main types of Brain Computer Interface (BCI) [2]: Invasive BCI interface where micro electrodes are implanted in human scalp. Partially invasive BCI interface that placed on the exposed surface of the brain, and finally, non-invasive BCI interface such as Electrocardiogram (EEG), Magneto encephalography (MEG), Electrooculography (EOG), and Magnetic Resonance Imaging (MRI), uses external sensors or channels. Figure 1 [3] illustrates the difference between invasive and non-invasive BCI interface.

There are many random wells in the city of Al-Lith, especially in the east of the city of Al-Lith in (the study area). There are no desalination companies in the area, and there are no data showing that the wells are potable & non-potable, and there is no information about the groundwater level in the area. In the beginning, the locations of the targeted wells were determined to conduct the study on, and then the samples were collected from the 20 identified sites in the east of the city of Al-Lith, from 20 wells, and the depth of each well was also determined. According to the results, the aim is to give idea for the water wells whether potable or non-potable.
