| 中文摘要: |
| 目的 基于可拓学优度评价法，对指夹式血氧仪产品进行可用性评价并优化。方法 采用文献研究法、用户访谈法、观察法和焦点小组方法选取产品可用性评价指标，从感知、外观和操作三个方面建立可用性评价指标体系。通过层次分析法计算得到评价指标的权系数，建立产品可用性的优度评价模型。对指夹式血氧仪进行初次评价，针对权系数高，优度低的可用性指标进行优化设计并验证。结论 通过指夹式血氧仪的设计实践，从现有产品的造型和界面入手，有效地提高了产品的舒适感并且缓解了新用户的使用压力。本方法能对指夹式血氧仪进行有效评价，发现其中存在的问题并加以改进。评价结果不但可以得出单项指标对产品可用性的影响，还可以全面展现产品的整体优度，进而可以进行有针对的优化设计。 |
| 英文摘要: |
| The work aims to evaluate the usability of and optimize the finger clip oximeter products based on the goodness evaluation method of extenics. Product usability evaluation indexes were collected by means of literature research, user interview, observation and focus group. A usability evaluation index system was established from the perspective of perception, appearance and operation. The weight coefficient of the evaluation index was obtained by the AHP method, and the goodness evaluation model of product availability was established. The initial evaluation of the finger clip oximeter was carried out, and the usability index with high weight coefficient and low goodness was optimized and verified. The work carries out the design practice of finger clip oximeter, effectively improving the comfort of the product and alleviating the pressure on new users starting from the shape and interface of existing products. The proposed method can effectively evaluate the finger clip oximeter, and find problems and improve them. The evaluation results not only reflect the impact of individual index on the product, but also fully reflect the overall goodness of the product and thus conduct targeted optimization design. |
