摘　　要：目的探究键盘的平曲类型以及键盘尺寸对用户的输入绩效和主观体验的影响。方法采用平、曲两种显示类型,并应用在三种键盘尺寸(39 cm×15 cm、52 cm×20 cm、65 cm×25 cm)得到了六种虚拟键盘。随后招募30名被试对这六种键盘进行了文本输入的被试内实验。结果曲面键盘在沉浸感的真实性维度上显著高于平面键盘(P=0.05),但降低了用户的输入绩效,体现在显著增加了用户的按键触发时间(Keystroke Reaction Time-KRT),P=0.007,并减少了每分钟单词输入数(Words Per Minute-WPM),P=0.001。不同按键尺寸对虚拟键盘也存在显著影响:与小尺寸相比,大尺寸按键键盘会显著提升用户的KRT(P=0.002)并显著降低错误率(P=0.002),但尺寸变化对WPM影响没有显著差异。结论本实验结果将为未来的虚拟现实键盘在样式和尺寸上的设计提供理论依据。Objective This study aimed to investigate the effects of keyboard layout(flat vs.curved)and keyboard size on user input performance and subjective experience.Methods This experiment employed two display types(flat and curved)and three keyboard sizes(39cm×15cm,52cm×20cm,65cm×25cm)to create six virtual keyboards.30 Participants were recruited to engage in a within-subject experimental design involving text input tasks on these six keyboards.Results The curved keyboard exhibited significantly higher levels of immersion realism compared to the flat keyboard(P=0.05).However,it resulted in decreased user input performance,as evidenced by a significant increase in Keystroke Reaction Time(KRT)(P=0.007)and a decrease in Words Per Minute(WPM)(P=0.001).Different keyboard sizes also had a significant impact on the virtual keyboards:compared to the small-sized keys,large-sized keys significantly increased KRT(P=0.002)and significantly reduced error rates(P=0.002),but there was no significant difference in WPM with size variations.Conclusion The results of this experiment provide a theoretical basis for the design of future virtual reality keyboards in terms of style and size selection.
