摘要
音频描述(AD)在使视障人士能够使用视听媒体、增强他们的体验和理解方面发挥着至关重要的作用。本研究采用了一个事件分割任务,来考察与无 AD 的健视观众相比,无视力者如何感知和分割有 AD 的电影中的叙事事件。本研究使用了两个《促进注意力发展》版本,在传达事件边界的明确程度上有所不同。结果显示,无视力者对事件边界的感知一般与有视力者相似,这肯定了反向增强技术在传达事件结构方面的有效性。然而,当关键事件边界的表达更加含蓄时,事件边界的识别能力就会下降。总之,这些研究结果为跨感官模式的事件分割过程提供了宝贵的见解。此外,它们还强调了反向视觉如何呈现事件边界的重要性,影响了视障人士对视听媒体的感知和解读,并为事件分割、多模态处理和视听无障碍提供了应用见解。
Event boundary perception in audio described films by people without sight
Audio description (AD) plays a crucial role in making audiovisual media accessible to people with a visual impairment, enhancing their experience and understanding. This study employs an event segmentation task to examine how people without sight perceive and segment narrative events in films with AD, compared to sighted viewers without AD. Two AD versions were utilized, differing in the explicitness of conveyed event boundaries. Results reveal that the participants without sight generally perceived event boundaries similarly to their sighted peers, affirming AD's effectiveness in conveying event structures. However, when key event boundaries were more implicitly expressed, event boundary recognition diminished. Collectively, these findings offer valuable insights into event segmentation processes across sensory modalities. Additionally, they underscore the significance of how AD presents event boundaries, influencing the perception and interpretation of audiovisual media for people with a visual impairment and providing applied insights into event segmentation, multimodal processing, and audiovisual accessibility.
