In View Of Senior Citizens Electronic Products Usability Research

This paper firstly brings out the present situation of the aging of population and its developing tend, analyzes the present existed disadvantages in electrical products for the old and its development prospects, and also analyzes ease of use of electrical products for the old based on psychology of the old, man-machine engineering and products semantics. It then, with a deep study on physiology and psychology and demand of the old, introduces scale design method and principles, including the detailed classification of objective users. The classification is based on the demands of objective users to fix the main functions, basic structure and principle design, basic shape design, size,color and other details design, evaluation,examination and correction program design. Design mainly covers five principles. Such as: focusing on the old, simplifying the practical operation, increasing feedback. Finally, scale design method and principles are tested by the practical example of mobile phone design for the old.
