基于“勒洛”三角形的扑克牌改良设计研究

Re-Designing Poker Based on Reuleaux Triangle

目的 针对当前传统长方形扑克牌收牌效率低、持握体验欠佳以及造型单一等问题,结合人机工程学进行以用户为中心的改良设计研究。方法 对国内市面上主流的长方形扑克牌进行个案分析,对用户使用过程中的行为进行梳理,并结合用户体验设计方法和人机工程学,利用“勒洛”三角形的等宽曲线特性以及稳定性,对该类扑克牌进行造型改良设计。结论 对用户使用扑克牌的全过程进行系统的用户研究,设计出一款便于用户抓握及操作的“勒洛”形扑克牌,该设计不仅丰富了传统扑克牌的造型设计,而且通过控制变量的相关实验,在实际的使用过程中,验证了改进后的扑克牌在收牌效率和抓握体验等方面有所提高,实验结果证明了该设计可以改善用户的使用体验。

This research aims to overcome these problems of existing poker cards,such as low efficiency,low hold-ability and limited shapes via combining ergonomics and user-centred method.Through the investigation and analy-sis of the existing playing cards,combined with the user experience and ergonomics,this research makes an improvement design by using the equal width curve characteristics and stability of Reuleaux triangle.Furthermore,the whole process of playing cards shall be studied first,a"Reuleaux triangle"shape was proposed.This shape was convenient for users to grasp and hold.The brand-new design is not only enriching the shape of traditional Poker cards,but also can improve the efficiency of card collection and grasping experience.Moreover,statistical analysis also shows that the design signifi-cantly creates greater the user experience.
