摘　　要：定向地图作为定向运动比赛过程中必备工具之一,其内容确定与表达直接影响比赛成绩及比赛公平性。为此提出一种新的定向越野可视化表达手段,即融合增强现实(augmented reality,AR)技术。首先,通过分析定向越野情境构成,近一步讨论了AR定向地图表达内容及表现形式,并将表达内容确定为警示信息、选手信息、赛道信息及定向地图4类;接着探讨了AR定向地图技术实现的可行性;最后就所设计符号展开问卷调查。结果表明,AR下的定向地图符号设计效果整体符合选手认知习惯,能够提高选手空间认知能力。As one of the necessary tools in the process of orienteering competition,the content and expression of the orienteering map directly affect the results and the fairness of the competition.This paper proposes augmented reality(AR)technology as a new visualization approach for the visualization of orienteering.First,the AR orienteering map expression content and expression form are discussed through the analysis of the orienteering context composition,and the expression content is determined as warning information,player information,track information and orienteering map four categories.Then the feasibility of AR orienteering map technology implementation is discussed.Finally,a questionnaire survey is conducted on the designed symbols.The results show that the overall effect of the orienteering map symbol design under AR is in line with the cognitive habits of the runners and can improve their spatial cognitive ability.
