移动触摸设备对老年人认知卸载的影响

Effects of Mobile Touch Devices on Cognitive Offloading for the Elderly

老年人身体机能和认知能力的下降影响了其与移动设备的交互能力,优化移动设备的交互方式是降低老年人认知负担的有效途径.采用改进的模式复制任务,结合主观评价法,探究移动触摸设备的输入和反馈方式对老年人认知卸载的影响.结果表明,输入方式主效应显著,其中手写笔条件下的老年人卸载了更多的工作记忆;反馈方式主效应显著,其中视听觉组合反馈下的老年人卸载了更多的工作记忆;输入和反馈方式均会影响老年人的满意度,其中老年人对手写笔和视听觉组合反馈满意度最高.移动触摸设备的输入与反馈方式是影响老年人认知卸载行为的重要因素,该结论为优化移动触摸设备的交互方式、降低老年人的认知负担提供了重要的参考依据.

The decline of physical function and cognitive ability of the elderly affects their ability to interact with mobile devices,and optimizing the interaction of mobile devices is an effective way to reduce the cognitive burden for the elderly.Accordingly,an improved pattern copy task combined with the subjective evaluation method was used to explore the influence of the input and feedback modes of mobile touch devices on the cognitive offloading for the elderly.The results showed that the main effect of input modes is significant,and the elderly are offloaded with more working memory under the stylus condition;the main effect of the feedback modes is significant,in which the elderly are offloaded with more working memory under the combined audiovisual feedback;both input and feedback modes affect the satisfaction of the elderly,and the elderly have the highest satisfaction with the combined stylus and audiovisual feedback.It was shown that the input and feedback modes of mobile touch devices are important factors affecting the cognitive offloading for the elderly.The conclusions provide an important reference for optimizing the interaction modes of mobile touch devices and reducing the cognitive burden for the elderly.
