4.1.7 Results
The final gesturable keypad sizes, which is analogous to handwriting was 11.82 mm. The core strip was 4.63 mm,
space required for top strip was 4.13 mm, and the space required for the bottom strip was 3 mm. We didn’t take the
left and right side into consideration as there are only few matras i.e. (aa, ee) which are added to the left and right of
the core strip in the form a straight line and could easily be accommodated in the square top keys.
