Abstract: | This paper describes a technique using dimensional analysis that so far has been rarely, if ever, used in studies of universal
access. However, this procedure can produce a robust decision support process for inclusive designs. In this paper, it is
applied to a case study of a wheelchair robot computer interface with choices in data input methods, addressing disparate
requirements of different groups of intended users. The main underlying issue is to combine technical measurements, speed
of operation and cost with subjective opinion. It turns out that Braglia’s method has greater robustness in determining rank
compared to standard techniques. In this, case a simple switch was rated better than a mouse or voice operation for control. |
