摘要
为了评价触控显示系统的人机交互工效,发展了一种面向神经工效学的多元评价方法,通过认知负荷和交互效率2个大方面、4个小指标(θ波功率、近似熵、误判率、反应间隔时间)进行多元评价.以座舱仪表界面为例设计了触控和操控2组对比实验,记录并分析操作者脑电信号及行为表现.分析结果表明:随着任务难度增大,误判率逐渐增大,同时θ波功率和近似熵整体逐渐增加,相关系数均大于0.5;触控实验中双手比单手操控交互效率更高,误判率和间隔时间平均降低15.3％、6.3％;触控式显示系统比模拟式系统认知负荷程度更低,θ波功率和近似熵平均降幅达24.7％和15.7％,交互效率更高,误判率和间隔时间平均降低69.9％和37.2％,表明触控式显示系统更具优势.
Abstract
A multiple evaluation method based on neuroergonomics is developed to evaluate the interaction efficiency of touch-control display system.This method involves the cognitive load and the interaction efficiency evaluation simultaneously from four indexes,i.e.,the power of theta wave value (Pθ),approximate entropy (ApEn),misjudgment rate (MR) and reaction time interval (RT).Taking the cockpit interface as example,two sets of contrast experiments are conducted separately under touch-control and non-touch conditions,and the performance and EEG signals of subjects are analyzed.It indicates that the misjudgment rate (MR) increases with the task difficulty,so as the cognitive load index Pθ and ApEn,and the correlation coefficients are all larger than 0.5; double-hand manipulation has higher efficiency than one-hand manipulation and the MR and RT are decreased by 15.3％ and 6.3％ on average; The Pθ and the ApEn are decreased by 24.7％ and 15.7％ under touch-control conditions,and MR and RT get lower by 69.9 ％ and 37.2 ％ on average than non-touch system.
