The Bijoy keyboard online layout was developed by Mustafa Jabbar in the 1980s as a way to make it easier for people to type in Bengali on computers. At the time, most Bengali typing was done using the English QWERTY keyboard, which required memorizing complex key combinations for each Bengali character.
Bijoy keyboard was the first Bengali keyboard layout that was designed to be intuitive and easy to use. It used a simple mapping of Bengali characters to the English keyboard, and included additional keys for characters not found on the English keyboard.
The Bijoy keyboard quickly gained popularity in Bangladesh and among Bengali-speaking communities around the world. It was included with many Bengali software packages, and became the de facto standard for typing Bengali on computers. In the early days, Bijoy keyboard was available only in software version which needs to install in the computer.
In recent years, with the rise of the internet, online versions of the Bijoy keyboard have become available, allowing users to type in Bengali using a standard QWERTY keyboard on any device with an internet connection. This ease of use made it more popular among the Bengali speaking people.
