A Quantitative Evaluation Method of Human Computer Interface´s Input-side of EMS

With the continuous advancement of computer input technologies, more input types could be chosen and used when designing the human-computer interface of EMS. In this premise, establishing the quantitative evaluation methods of human computer interface´s input-side of EMS is required. This paper presents a quantitatively evaluation method of three design elements, namely operating efficiency, cognitive load and naturalness. The structured visual manner is proposed for showing the evaluation results. At last an example is realized. With the help of the evaluation, the designers are able to compare various input types and select the right one reasonably.
