Abstract In this study, questionnaire and observation method were prepared to determine and establish the functional requirements of a mobile phone intended for the visually impaired individuals. Correspondingly, a total of eight correspondents that have either congenital and acquired blindness were surveyed, which is composes of equal number of gender with an age bracket of 28 to 51 years old and having an educational level from secondary to graduate school. The questionnaire were designed to address and investigate the three major points, (1) life style, this is to determine the habitual frequency or occasion of using mobile phone; (2) satisfaction, this is to figure out the degree of satisfaction of the operational functions of the current available mobile phone; (3) researchers surveyed results on the demand of the various functions from the different users, this is to understand and include the real demand for those visually disabled. Consequently, each of those correspondents revealed that they have been using a mobile phone for at least 10 years and the questionnaire results stated a need of an appropriate functional planning of a special mobile phone which is suitable to those having visual impairment. Moreover, this study proposed three innovative design elements, and these are voice interface guidance system, six dot Braille input method system, and GPS pedestrian navigation system.
