摘要
鼠标日渐成为儿童使用频率相当高的产品,非儿童专用鼠标带来的不良的操作姿势,将导致儿童成年之后的健康问题。用户的指肚、近端指间关节、掌指关节、掌靠部位为鼠标操作接主要触点,合理确定鼠标外形中这些关键点的位置,将为用户提供有效的支撑并减少手部的操作调节,保证健康操作需求。以手部的生理结构为基础,结合手工具设计原则,分析上肢末端累积性损伤与手部位移和支撑间的联系,总结关键点对于鼠标外形设计的主要影响。以百分位为主要分析手段对样本数据进行典型尺度等级划分,利用关键点数据构建曲面,完成儿童鼠标外形设计。归纳设计过程的内在逻辑关系,为相关手持产品设计提供新的参考方法。通过数据调查、油泥模型制作、数据分析取用和数字模型的构建验证各关键点数值的合理性,同时测量数据也为相关同类型产品的深入设计打下了基础。
The mouse has become a kind of children＇s products with high frequency. Badness operation posture will lead to children＇s health problem. There are some points often touch mouse in the operation, which include five finger belly, proximal interphalangeal joint, metacarpophalangeal joint, and three contacting points of palm. Appropriate design the location of these points on mouse shape will provide effective support and reduce the operation of the hand adjustment, meet the healthy requirements in operation. The relationship between upper limbs extremity cumulative trauma and hand moving and support is analyzed based on the principles of hand tools and hand physiological structure. The main impacts of key point to mouse shape design are summarized. The method of percentiles is used to get typical scale of classification of sample data in design progress. The data of key point is used to build the three-dimensional, complete the children＇s mouse shape design. The internal logic of the design process is summed up. It provides a new reference for the design method of relevant hand-held product. The reasonableness of key point is verified through survey data, clay modeling, data analysis, construction of digital model. Those measurement data of key points makes foundation for further study of similar products.
