What is it about?
Mobile devices are now very common among all of us. However, a person with visual impairment can not use such a device. A mechanism is proposed in this work so that people with visual impairment can use such a device to compose their texts. The mechanism considers small eight directional moves on the touch screen

Why is it important?
It is simple and accurate. Users do not require any location accuracy and thus less error-prone. Small directional movements are very fast for interaction. If users are familiar with the 4x3 telephone keypad layout, it will be advantageous for them.
Perspectives
This is a novel approach to bridge a digital divide. There is more scope of improvement and hence future research to carry forward the idea, in particular, to have an alternative interaction mechanism for people with special needs.
