Walking and seeing - about the interaction of walking and visual in-formation processing

移动的技术，例如移动的电话或数据眼镜，需要越来越多的认知/注意力资源来在行走时处理数字化丰富的视觉信息。这种资源在同时运动和信息获取之间的划分承担着对这两项任务产生负面影响的风险。更具体地说，可以假设视觉信息摄入影响步态，但步态控制的挑战也可能导致视觉感知受损。因此，只有在已知这种相互依赖的影响变量和限制的情况下，才能安全地使用在步行过程中传递信息的可穿戴技术。本项目的目的是在基础研究的水平上系统地研究视觉信息处理需求与步态之间的相互作用。因此，同时行走和观看的二元体需要在系统地相互建立的环境中进行整体研究，增加生态有效性-或接近现实。借助现代测量方法（移动的EEG、移动的眼球跟踪、运动捕捉）以及能够系统显示虚拟环境的检查环境（在交互式步态实验室"步态实时交互实验室"，GRAIL），将研究发生干扰的原因和影响。

Mobile technology, such as mobile phones or data glasses, requires more and more cogni-tive/attentional resources to process digitally-enriched visual information while walking. The division of such resources between concurrent locomotion and information acquisition bears the risk of having a negative impact on both tasks. More specifically, it can be assumed that visual information intake influences gait, but also that challenges to gait control can lead to impaired visual perception. Wearable technologies that convey information during walking can therefore only be used safely if the influencing variables and limits of this mutual dependency are known. The aim of this project is to systematically investigate the interactions between the demands of visual information processing and gait on the level of basic research. Therefore, the dyad of concurrent walking and seeing needs to be investaigaed holistically in settings that systematically build on each other with increasing ecological validity – or closeness to reality. With the help of modern measurement methods (mobile EEG, mobile eye tracking, motion capturing) as well as examination environments that enable the systematic display of virtual environments (in an interactive gait laboratory, "Gait Realtime InterActive Lab", GRAIL), causes and effects of occurring interferences will be investigated.
