工作的数字化转型扩展到体力劳动领域,需要评估智能设备的认知人体工程学。评估施加在工人身上的认知工作量和注意力过程尤其重要。我们在模拟订单拣选任务的背景下比较了两种智能设备之间的人类表现。为此,我们结合了任务切换范式与侧翼任务。反应时间,错误率和主观任务负荷指数进行了登记。与耳机相比,参与者使用智能眼镜的速度较慢,然而,使用智能眼镜,他们不太容易分心,反应更灵活。性能差异可以解释由特定模态转换从感官输入到手动响应。总之,结果表明,智能眼镜可能更适合在依赖视觉信息的相当复杂的任务中传达信息,而耳机可能更适合在整洁的环境中执行简单的任务。
Digital transformation of work expands in manual labor areas, providing the need to assess cognitive ergonomics of smart devices. Evaluating cognitive workload imposed on the worker and attentional processes are especially relevant. We compared human performance between two smart devices in the context of a simulated order picking task. To this end, we combined a task switching paradigm with a flanker task. Response times, error rates and subjective task load indices were registered. Participants were slower in using smart glasses compared to a headset, however, with smart glasses they were less distraction-prone and more flexible in their responses. The performance differences may be explained by modality-specific transformations from sensory input to manual responses. In sum, results suggest that smart glasses may be more suitable for conveying information in rather complex tasks relying on visual information whereas headsets may be more suitable for simple tasks in uncluttered environments.
