  • Abstract In recent years the popularity of transport tools has shown its importance to stroke
    and mobility-impaired patients as well as old people. In addition, due to the
    development of lightweight materials and intensive battery, the adoption of electric
    wheelchair has been gradually increased; however, as there is a movement difference
    between the disabilities and the caregivers, a universal design for electric wheelchair is
    necessary. The experiment of this research had been conducted in three phases. The
    first phase was a questionnaire survey to wheelchair user groups of lower extremity
    disabilities concerning the operational problems of existing commercial electric
    wheelchairs. The second phase was to have subjects, by using universal design PPP
    (Product Performance Program) scale , assess the electric wheelchair operated video
    shoot and conduct factor analysis to obtain the association between the universal design
    principles and design elements. The third was to conduct design improvement based on
    the findings of factor analysis and used universal design PPP scale to assess the
    modified design project. The research findings of the first phase demonstrated that
    problems for lower extremity disabilities to commercial electric wheelchair are: (1)
    clothing, towels are easy to clip into the wheel circle and hand rims. (2). Inconvenience
    in battery change while charging (3), Inconvenience in wheelchair folding or unable to
    fold. (4). Uneven balance and hard to keep straight (5). Hands tend to be clipped by
    iv
    wheel frames, wire, or hand rim while in steering. (6). Limited storage space. On
    using universal design PPP scale to conduct factor analysis to obtain the association
    between the universal design principles and design elements. There were three major
    components extracted from the remaining variables through factor analysis (UD
    Guideline Items) , with 71% explained rate. The first major component composed of
    eight principles. The second major component consisted of two principles o; the third
    one included one principle. The findings of final phase which used universal design
    PPP scale to assess the modified design project based on the necessary design process,
    showed that the folding hand-wheel motor-driven electric wheelchair under the design
    elements corresponding with general principles was the most satisfied one.In recent years the popularity of transport tools has shown its importance to stroke
