Abstract: With the onset of electric and electronic technology, the world has taken a metamorphic change from the mammoth size of an elephant to that of a tiny ant. The coaxial cable bridges encircle the spear which generates them. By far, the mobile phones have been the most advanced invention of the human race, and they have contributed an incredible part in the lifestyle of people of all walks of life. The handy phones (Clarridge, 2009) have succeeded in communication, kindred activities. There is a host of methods by which the visually challenged people use the mobile for their multifarious activities. Our focus here is to recount salient features of diverse interaction approaches followed by this vulnerable segment of society to interact with touch-based mobile phones. Thus, in this document, an earnest effort is made to assess various interaction, methods in terms of several features like the implication of interaction design, design philosophy, concrete usability study measures, favourable factors, divergence in utilisation so as to put them in a nutshell. A case study on the interaction approaches of the visually challenged with mobile phones is also offered here along with an evaluation of the text input time for several text input techniques, though as per the observation there is no major divergence in the text input time.

Keywords: survey on interaction techniques; Braille coded text entry; comparative study; touch screen text entry; text entry in mobile; text entry by blind; visually impaired.
