Based on Upper Extremity Comfort ROM of Ergonomic Methods for Household Products Design
The structure of product demands a higher level of user performance and involves risk that may possibly negatively impact the user’s safety and health. For this reason, the evaluation or design of new products requires extensive knowledge of human interaction, including the operation and comfort of motion. This paper presents a technique for assessment of the upper extremity comfortable ROM. The method is based on new experimental data from perceived discomfort of subjects, and uses digital human modeling (DHM) systems to verify the perceived discomfort rank. 55 participants participated in this experiment. They were required to extract and insert pegs from different panels. We get the comfort ROM of subjects according to subjective comfortable ratings and use digital DHM systems to verify the perceived discomfort rank. In this paper, comfortable motion range of the 50th percentile was shown only. Using DHM systems, we can supply upper limb comfortable motion range of different percentile Chinese people for household products ergonomics design.
