本研究针对XR体育观赛中语音查询歧义导致的误读问题，构建外部化查询解释的设计空间并开发XR足球系统，用户研究显示外部化可提升可检查性但存在可见性-行动差距。
AI 中文摘要
沉浸式体育（XR sports）观赛让观众能从沉浸式、空间锚定视角跟进比赛，同时直接在场景内获取上下文分析数据。这类场景中，语音是实用的交互模态，因为文本输入和菜单导航会打断快节奏比赛时的注意力。但语音查询常不够明确：观众可能省略目标球员、时间段、场地位置或指标。若系统隐式解决歧义，其假设会隐藏，导致误读难察觉、难修正。本研究探讨在XR体育观赛中，外部化系统对语音查询的解释如何支持对这类误解的检查与修正。通过形成性研究，识别出该场景下语音查询的四类常见歧义类型：指称型、空间型、时间型和指标型。本研究构建设计空间，沿三个维度组织外部化内容（歧义类型、解释状态、外部化策略），并将其实例化为交互式XR足球观赛系统，结合场景化视觉线索与辅助分析视图。采用被试内设计的用户研究（N=16），对比外部化解释与仅语音基线，发现外部化在多数测量维度上与更高可检查性及更多明确修正语言相关。但仅38%的外部化错位试次发生修正，且该可见性-行动差距随歧义类型变化，表明透明度与修正 affordance 是正交的设计轴。
英文摘要
XR sports viewing enables spectators to follow play from immersive, spatially anchored perspectives while accessing contextual analytics directly within the scene. In such settings, speech offers a practical interaction modality because text entry and menu navigation can interrupt attention during fast-paced gameplay. However, spoken queries are often underspecified: viewers may omit which player, time period, field location, or metric they intend. When systems resolve these ambiguities implicitly, their assumptions remain hidden, making misinterpretations difficult to notice and correct (repair). We investigate how externalizing a system's interpretation of spoken queries can support inspection and correction of such misunderstandings in XR sports viewing. Through a formative study, we identified four recurring ambiguity types (referential, spatial, temporal, and metric) that characterize ambiguous spoken queries in this context. We develop a design space that organizes externalization along three dimensions (ambiguity type, interpretation state, externalization strategy) and instantiate it in an interactive XR soccer viewing system that combines situated visual cues with supporting analytic views. A within-subjects user study (N=16) comparing externalized interpretation against a voice-only baseline reveals that externalization is associated with higher inspectability on most measured dimensions and increased explicit repair language overall. However, repair occurred in only 38% of misaligned externalization trials, and this visibility-action gap varied by ambiguity type, indicating that transparency and correction affordance are orthogonal design axes.
