我们研究了步态和智能设备对选择性注意的影响,采用任务切换范式和埃里克森侧翼任务的订单采摘设置。提示指示相关的客户订单(两个任务之一),从而通过智能眼镜或耳机指示正确的刺激反应规则。任务转换(重复与切换)在混合块中随机变化,在单个块中保持不变。参与者(n = 24)被要求对一个五个字母的字符串的中心字母进行分类,并手动回答(左与右)。重要的是,中心字母与周围字母要么一致,要么不一致。参与者要么以个人舒适的速度行走,要么站在跑步机上。我们将响应时间和错误率登记为因变量。特定智能设备和行走条件的组合决定了对注意力的影响,从而决定了订单拣选员的精神状态:在混合任务响应时间中,使用耳机的切换成本高于智能眼镜,而戴着智能眼镜行走时,不一致的侧翼尤其有害。在单一任务错误中,耳机使用的一致性效应比智能眼镜更明显,但仅在站立时,而不是在行走时。结果表明,上下文特定的影响,表明步态速度和性能要求,可以被用来作为认知负荷指标的技术系统,以适应指令。
We investigated the influence of gait and smart devices on selective attention in an order picking setting employing a task switching paradigm and an Eriksen flanker task. A cue indicated the relevant customer order (one of two tasks) and thereby the correct stimulus-response rule either via smart glasses or headset. The task transition (repetition vs. switch) was varied randomly in mixed blocks and kept constant in single blocks. Participants (n = 24) were asked to classify the central letter of a five-letter string with a manual response (left vs. right). Importantly, the central letter was either congruent or incongruent with the surrounding letters. Participants were either walking at their personal comfort speed or standing on a treadmill. We registered response times and error rates as dependent variables. The combination of a particular smart device and walking condition determined the effect on attention and thus the order picker’s mental state: In mixed task response times, switch costs were higher for headset use than smart glasses, while incongruent flankers were especially harmful while walking wearing smart glasses. In single task errors, congruency effects were more pronounced for headset use than smart glasses but only while standing, not while walking. Results show context-specific effects, suggesting that gait speed and performance requirements can be used as cognitive load indicators in technical systems to adapt instructions.
