The stark reality I observed was that the lack of intuitive input and feedback mechanisms effectively locked blind individuals out of the world of touchscreen mobile text entry, particularly in Indian languages. This realization ignited a passion to bridge this digital divide. My project directly addressed this critical accessibility gap by aiming to develop an effective mobile touchscreen keyboard specifically designed for blind users to type in Malayalam.

My approach was rooted in deep understanding. I meticulously studied existing Indian language keyboards and, crucially, learned firsthand how blind users currently navigate and struggle with these interfaces. The insights gained from this research formed the bedrock of my keyboard layout designs. To compensate for the absence of vision, I focused on a multi-sensory experience, substituting sight with carefully calibrated haptic feedback to guide finger placement and voice feedback to provide crucial information about the typed characters. This dual feedback system was designed to keep the user constantly aware of their location on the screen and to offer two vital layers of confirmation: 'What am I currently typing?' and 'What have I already typed?'

The culmination of this user-centered design process was Mudra: Interface Design, a novel keyboard layout and interaction paradigm. The impact of this design was tangible and measurable. After a focused training period of just three hours using 100 complex Malayalam words, users achieved an average typing speed of 1.05 words per minute. Even with a minimal initial training of 30 minutes using only 10 words each, users demonstrated a mean typing speed of 0.41 words per minute. These results, while initial, represent a significant step forward in empowering blind individuals to communicate effectively and independently using touchscreen technology in their native language. Mudra wasn't just a keyboard; it was a key to unlocking digital inclusion and fostering greater autonomy for visually impaired Malayalam speakers.
