Thai Pattachote keyboard layout

Pattachote keyboard is a Thai keyboard layout invented by Sarit Pattachote, because Sarit's research suggests that the Kedmanee layout uses the right hand more than the left hand, and the right little finger is used used heavily. Thus, he invented the Pattachote keyboard layout.

Research by The National Research Council of Thailand suggests that the Pattachote system can be typed faster than the Kedmanee layout, but the Kedmanee layout has been in use longer and is more popular.
