This study aimed to determine the touch characteristics during tapping tasks on membrane touch interface and investigate the effects of posture and gender on touch characteristics variables. One hundred participants tapped digits displayed on a membrane touch interface on sitting and standing positions using all fingers of the dominant hand. Touch characteristics measures included average force, contact area and dwell time. Across fingers and postures, males exerted larger force and contact area than females, but similar dwell time. Across genders and postures, thumb exerted the largest force and the force of the other four fingers showed no significant difference. The contact area of the thumb was the largest, whereas that of the little finger was the smallest; the dwell time of the thumb was the longest, whereas that of the middle finger was the shortest. Relationships among finger sizes, gender, posture and touch characteristics were proposed. The findings helped direct membrane touch interface design for digital and numerical control products from hardware and software perspectives. Practitioner Summary: This study measured force, contact area and dwell time in tapping tasks on membrane touch interface and examined effects of gender and posture on force, contact area and dwell time. The findings will direct membrane touch interface design for digital and numerical control products from hardware and software perspectives.

本研究旨在确定在薄膜触摸界面上进行点击任务时的触摸特性，并研究姿势和性别对触摸特性变量的影响。100名参与者使用优势手的所有手指，在坐着和站着的姿势下点击显示在薄膜触摸界面上的数字。触摸特性测量包括平均力、接触面积和停留时间。在不同手指和姿势中，男性施加的力和接触面积比女性大，但停留时间相似。在不同性别和姿势中，拇指施加的力最大，其他四个手指的力没有显著差异。拇指的接触面积最大，而小指的接触面积最小；拇指的停留时间最长，而中指的停留时间最短。提出了手指大小、性别、姿势和触摸特性之间的关系。这些发现有助于从硬件和软件角度指导数字和数控产品的薄膜触摸界面设计。从业者总结：本研究测量了在薄膜触摸界面上进行点击任务时的力、接触面积和停留时间，并研究了性别和姿势对力、接触面积和停留时间的影响。这些发现将从硬件和软件角度指导数字和数控产品的薄膜触摸界面设计。缩写：M：平均值；SD：标准差；ISO：国际标准化组织；LCD：液晶显示器；ANOVA：方差分析；ANSI：美国国家标准学会；HFES：人类因素与工效学协会。
