Onehanded Coder:An Accessible Codind Environment for Single Handed Users

The advancement of digital technologies and the growing dependence on coding platforms have made programming skills a necessity for students and professionals. The majority of available programming environments are, however, aimed at users with complete twohanded capabilities, and they pose severe restrictions for people with motor impairments or one-handed users. This paper presents Onehanded Coder, a web-based coding system of minimal weight specifically designed to increase software development accessibility and inclusivity. The system offers crucial features like syntax highlighting, autocompletion, inline error checking, shortcutbased workflows, and on-the-fly program execution while maintaining low mouse navigation dependency. Built on a current technology stack of HTML, CSS, JavaScript, React.js, Node.js, and MongoDB, the system balances functionality and usability. Systemic testing has validated its efficiency in safe authentication, file handling, program compiling, and running. The findings reveal Onehanded Coder minimizes physical exertion, eases coding activities, and provides a seamless user experience on devices. By merging accessibility with effectiveness, the system supports equal opportunities for students and developers and lays the groundwork for more inclusive technology tools in the future.
