A “research paper” from Fujitsu describing the design process for creating a phone for elderly or disabled people. Clearly shows design considerations.
“Fujitsu�s Raku Raku PHONE is an easy-to-use mobile phone for elderly persons, persons unfamiliar with mobile-phone operation, and persons with physical disabilities, for example, persons with visual disabilities. This highly accessible, userfriendly mobile phone makes full use of speech synthesis and voice recognition technologies and achieves good universal design through an ingenious combination of hardware, software, and user interface. In the development phase, we adopted a special process to aggressively research and evaluate product usability from users� viewpoints, clarify existing problems, and improve the design and user interface of mobile phones. This paper describes the steps taken to achieve universal design in the Raku Raku PHONE and the universal design features of its hardware, software, and audio functions.”
