Abstract

We examined the minimum latency required to locate and identify a visual target (visual search) in a two-alternative forced-choice paradigm in which the visual target could appear from any azimuth (0 degree to 360 degrees) and from a broad range of elevations (from 90 degrees above to 70 degrees below the horizon) relative to a person's initial line of gaze. Seven people were tested in six conditions: unaided search, three aurally aided search conditions, and two visually aided search conditions. Aurally aided search with both actual and virtual sound localization cues proved to be superior to unaided and visually guided search. Application of synthesized three-dimensional and two-dimensional sound cues in the workstations are discussed.

摘要

我们在二选一强制选择范式中，研究了定位并识别视觉目标（视觉搜索）所需的最短潜伏期。在此范式中，视觉目标相对于人的初始视线，可从任何方位（0度至360度）以及广泛的仰角范围（从地平线以上90度至地平线以下70度）出现。七名受试者在六种条件下接受了测试：无辅助搜索、三种听觉辅助搜索条件以及两种视觉辅助搜索条件。事实证明，结合实际和虚拟声音定位线索的听觉辅助搜索优于无辅助搜索和视觉引导搜索。本文还讨论了在工作站中合成三维和二维声音线索的应用。
