触摸屏输入键与其他信息争夺有限的屏幕空间。本研究估计了不会降低性能或用户满意度的最小密钥大小。二十名参与者站在触摸屏亭前，用手指触摸在电容触摸屏上显示的数字键盘上输入一个、四个或10个数字。将键尺寸（10、15、20、25 mm正方形）和边缘到边缘键间距（1、3 mm）按工厂组合。通过响应时间和错误来评估性能，并获得用户偏好。间隔没有可测量的影响。输入时间更长，错误更高，较小的关键尺寸，但没有显着差异，发现20和25毫米的关键尺寸之间。参与者也喜欢20毫米的关键，以较小的关键，他们之间的20和25毫米的关键。因此，发现20 mm的钥匙尺寸对于着陆钥匙进入来说足够大。
Touch screen input keys compete with other information for limited screen space. The present study estimated the smallest key size that would not degrade performance or user satisfaction. Twenty participants used finger touches to enter one, four or 10 digits in a numeric keypad displayed on a capacitive touch screen, while standing in front of a touch screen kiosk. Key size ( 10, 15, 20, 25 mm square) and edge-to-edge key spacing ( 1, 3 mm) were factorially combined. Performance was evaluated with response time and errors, and user preferences were obtained. Spacing had no measurable effects. Entry times were longer and errors were higher for smaller key sizes, but no significant differences were found between key sizes of 20 and 25 mm. Participants also preferred 20 mm keys to smaller keys, and they were indifferent between 20 and 25 mm keys. Therefore, a key size of 20 mm was found to be sufficiently large for land-on key entry.
