HandiMathKey: Mathematical Keyboard for Disabled Person

To type mathematical formula is a tedious task for all of us with the usual applications. Moreover, this task is very tiring for motor impairment. This paper describes the user centred methodology used to design the HandiMathKey virtual keyboard to type more easily the mathematical formula. Then we present a case study that compares the entry time between HandiMathKey and Word office for the mathematic formulas typing. This study shows that the HandiMathkey is easier to use and more efficient.
