The ideal mind speller which is being developed by the researchers from Imec. The lab of Neuro and psychophysiology created the word processor. The mind speller will be helpful for those with brain paralysis and speech disabilities. The mind speller is a easy portable, intelligent textual verbal communication prototype device. The EEG which means electro encephalogram which is present in the mind speller.

The brainwaves are interpreted into words and phrases by the mind speller. The P300 brainwaves are detected and interpreted by the mind speller. The portable device of the mind speller is the size of a match box. The portable device is connected to the electrodes which is located to the specific positions of the brain. The connection of the electrodes captures the suitable EEG signals from the brain.

The circuit was designed by the Imec and Holst centre. The data collected from the person is seen on the computer by the signal received. The market has many mind interpreters available but they are very expensive. The mind speller is user friendly and a generic device and cost efficient too. The power efficient chip is the reason behind the affordability, easy to wear for motor disability people.
