Abstract
Keywords：In-vehicle HCI interface, ERP, Attention resource, P1 component, Visual search 5 As transportation systems become more intelligent, attention allocation during driving 6 human-computer interaction(HCI) has emerged as a key research focus. This study designed 7 an event related potentials(ERP)-based cognitive retrieval experiment, twelve participants 8 were recruited to simulate driving-related human-computer interaction. By recording 9 electroencephalogram(EEG) activity in response to different prompt spaces, the study 10 evaluated attention allocation and explored how drivers distribute attention within interfaces. 11 The results showed that drivers exhibited an attentional bias toward the lower-left area of the 12 interface, with larger P1 amplitudes (p=0.005) recorded in the frontal cortex. This finding 13 reveals that spatial prioritization exists in the design of vehicle HCI interfaces and impacts 14 drivers' cognitive evaluations. Early ERP components demonstrated sensitivity in assessing 15 this phenomenon. The study provides new insights into the interaction and cognition within 16 vehicle interfaces in driving environments.
