Table 3: comparative study with other keyboard From the above table we can easily find out that our keyboard layout is optimal. Here we work with total 856725 character (with out space). In Bijoy the load in left is very large than right hand. And hand switching is also smaller than us. Increasing of the data this ratio also increased highly. On the other our keyboard layout is optimal because we design the layout by mining the proper association of letter each other in the various kinds of thoroughly. Not only depend on the frequently occurring monograph, digraph, etc. As for why our keyboard layout shows maximum hand switching than also proposed keyboard layout 3. In the above the table not determining characters are large because here we do not consider 0 to 10, united font etc. From the above data it is clear that our proposed layout divides the load on both hand equally and hand switching is also maximize. Comparing with other keyboard layout we can say that, our proposed layout is optimal. 

## 6. Conclusion

. So it is the time to research on this portant field. The Bangla academy also can come forward to finalize such an important matter and would produc ngladesh for new The use of Bangla keyboard layout is increasing day by day im e an optimal keyboard layout and circular throughout Ba generation. Our keyboard layout shows maximum hand switching than any other exiting keyboard and also cost effective because frequently occurred letter is distribute closer to finger. 

Experimental results show that our proposed layout is more scientific and user friendly. If our keyboard layout is implemented, we hope that people will be benefited.
