ABSTRACT Hiking-time formulas attempt to predict the time required for a hike based on available data. Most known hiking-time formulas can be classified into either pace-based, requiring the elevation profile as input, or formulas having horizontal distance , cumulative elevation gain and loss as input. In the first part of the paper, we discuss some known formulas, give a list of desirable features of such pace-based functions, discuss advantages and disadvantages of the two approaches and the connection between them. It turns out that only linear functions with input and have uniquely identifiable pace-based function counterparts. Then. we demonstrate how such simple linear functions with input and can be constructed for individuals provided enough hiking data are available, using a case study of four hikers. We also include simple adjustments for the formulas based on the elevation of start and end point of the hike. Although no statistically valid conclusions can be drawn from such a small nonrandom sample, the results still give some insight into practical questions for hikers.
摘要徒步旅行时间公式试图根据现有数据预测徒步旅行所需的时间。大多数已知的徒步旅行时间公式可以分为基于速度的、需要高程剖面作为输入的公式,或者具有水平距离、累积高程增益和损失作为输入的计算公式。在本文的第一部分,我们讨论了一些已知的公式,给出了这种基于速度的函数的理想特征列表,讨论了这两种方法的优缺点以及它们之间的联系。事实证明,只有具有输入的线性函数和具有唯一可识别的基于速度的函数对应。然后通过对四名徒步旅行者的案例研究,我们展示了在有足够徒步数据的情况下,如何为个人构建这种简单的线性函数。我们还根据远足起点和终点的高程对公式进行了简单调整。尽管从如此小的非随机样本中无法得出统计上有效的结论,但这些结果仍然为徒步旅行者的实际问题提供了一些见解。

ABSTRACT Augmented Reality (AR) is a technology that has been used extensively in the field of cartography, with one particular application being that of navigation. However even now, AR in navigation is still at an active exploratory stage with multiple different approaches regarding the techniques, methodologies, and development processes. In this work, we present a systematic review of application development in AR navigation research, aiming to fill the gap in the literature by identifying trends in aspects such as hardware, software, and methodologies in AR navigation. We review 107 publications from the past 25 years that present AR navigation software for real-world environments, and analyze their main characteristics regarding intended environments and users, hardware, development platforms, and AR methodologies. We note a rise in AR navigation research interest from 2010 onward, driven in large part by smartphone and mobile device ubiquity, supported further by significant advances and streamlined processes in AR application development. Furthermore, we highlight a rise in the use of increasingly more complex AR methodologies in recent years, signaling that the field is steadily evolving and maturing. At the same time, we also identify significant inconsistencies and omissions regarding the reporting of technical details, with nearly half of reviewed works not reporting one or more of the aspects of interest. After identifying the level of maturity and complexity in the field AR navigation, we provide a list of recommendations and future directions for researchers aiming to develop AR navigation applications.
增强现实技术是一种在地图绘制领域得到广泛应用的技术,其中一个特殊的应用就是导航。然而,即使是现在,导航中的AR仍然处于积极的探索阶段,在技术、方法和开发过程方面有多种不同的方法。在这项工作中,我们对AR导航研究的应用开发进行了系统的回顾,旨在通过确定AR导航的硬件、软件和方法等方面的趋势来填补文献中的空白。我们回顾了过去25年的107份出版物 年,介绍了用于真实世界环境的AR导航软件,并分析了它们在预期环境和用户、硬件、开发平台和AR方法方面的主要特征。我们注意到,自2010年以来,AR导航研究的兴趣有所上升,这在很大程度上是由智能手机和移动设备的普遍性推动的,并得到了AR应用程序开发的重大进展和简化流程的进一步支持。此外,我们强调,近年来,越来越复杂的AR方法的使用有所增加,这表明该领域正在稳步发展和成熟。与此同时,我们还发现了技术细节报告方面的重大不一致和遗漏,近一半的审查作品没有报告感兴趣的一个或多个方面。在确定了AR导航领域的成熟度和复杂性之后,我们为旨在开发AR导航应用的研究人员提供了一份建议和未来方向列表。

ABSTRACT Dashboards are an increasingly popular form of data visualization. Large, complex, and dynamic mobility data present a number of challenges in dashboard design. The overall aim for dashboard design is to improve information communication and decision making, though big mobility data in particular require considering privacy alongside size and complexity. Taking these issues into account, a gap remains between wrangling mobility data and developing meaningful dashboard output. Therefore, there is a need for a framework that bridges this gap to support the mobility dashboard development and design process. In this paper we outline a conceptual framework for mobility data dashboards that provides guidance for the development process while considering mobility data structure, volume, complexity, varied application contexts, and privacy constraints. We illustrate the proposed framework’s components and process using example mobility dashboards with varied inputs, end-users and objectives. Overall, the framework offers a basis for developers to understand how informational displays of big mobility data are determined by end-user needs as well as the types of data selection, transformation, and display available to particular mobility datasets. Key policy highlights Defines essential components of big mobility dashboards for stakeholders to understand key considerations and data management/pre-processing needs Clarifies the differences between dashboards and visual analytics applications Provides guidance for gathering information from end-users to ensure displays are fit-for-purpose Illustrates the application of the conceptual framework for dashboard design by discussing several examples of mobility data dashboards
摘要仪表板是一种越来越流行的数据可视化形式。庞大、复杂和动态的移动数据在仪表板设计中提出了许多挑战。仪表板设计的总体目标是改善信息沟通和决策,尽管大的移动数据尤其需要在考虑大小和复杂性的同时考虑隐私。考虑到这些问题,在争论移动数据和开发有意义的仪表板输出之间仍然存在差距。因此,需要一个框架来弥补这一差距,以支持移动仪表板的开发和设计过程。在本文中,我们概述了移动数据仪表板的概念框架,该框架为开发过程提供了指导,同时考虑了移动数据结构、数量、复杂性、各种应用程序上下文和隐私限制。我们使用具有不同输入、最终用户和目标的示例移动仪表板来说明拟议框架的组件和流程。总体而言,该框架为开发人员提供了一个基础,让他们了解大型移动数据的信息显示是如何由最终用户需求以及特定移动数据集可用的数据选择、转换和显示类型决定的。关键政策亮点为利益相关者定义大型移动仪表板的重要组件,以了解关键考虑因素和数据管理/预处理需求澄清仪表板和可视化分析应用程序之间的差异为从最终用户收集信息提供指导,以确保显示符合目的图示概念通过讨论移动数据仪表板的几个示例实现仪表板设计框架

ABSTRACT Road network matching that detects arc-to-arc relations is a crucial prerequisite for the update of road data. The increasing complexity of multi-source and multi-scale road network data challenges the existing methods on accuracy and efficiency. This paper focuses on the interactive-based probabilistic relaxation approach. It is difficult to obtain satisfactory results by using completely automatic matching algorithm in some complicated road networks such as multi-lane carriageways. We try to improve the matching accuracy by combining optimization matching model with manual interaction. The method uses the module of active learning to construct unlabeled sample pool from preliminary matching of probabilistic relaxation, and then selects the arcs with the highest uncertainty by query function. The selected road is then handed over to humans to determine its arc-to-arc relations in the other road network. Finally, the matching parameters are automatically adjusted according to the user’s feedback information, so as to realize the dynamic optimization of the model. Our interaction method is efficient as it only needs to specify few arc-to-arc mappings and others can be amended automatically. Our experimental results reveal that active learning can substantially improve the performance of standard probabilistic relaxation algorithms in road network matching.
检测圆弧间关系的道路网络匹配是道路数据更新的关键前提。多源多尺度路网数据日益复杂,对现有方法的准确性和效率提出了挑战。本文主要研究基于交互的概率松弛方法。在多车道等复杂的道路网络中,采用完全自动匹配算法很难获得满意的结果。我们试图通过将优化匹配模型与人工交互相结合来提高匹配精度。该方法利用主动学习模块从概率松弛的初步匹配中构建未标记样本库,然后通过查询函数选择不确定性最高的弧。然后将选定的道路移交给人类,以确定其在另一道路网络中的弧对弧关系。最后,根据用户的反馈信息自动调整匹配参数,实现模型的动态优化。我们的交互方法是有效的,因为它只需要指定几个弧到弧的映射,其他映射可以自动修改。我们的实验结果表明,主动学习可以显著提高标准概率松弛算法在道路网络匹配中的性能。

ABSTRACT The indoor layout map contains information about the architectural interior space. Users often utilize the You-Are-Here (YAH) symbol on maps to firstly determine their current location and orientation to find the direction of a target location. Circle symbols often seen only indicate a user’s location, making it difficult to complete the orientation process. Based on alignment effect theory, we modified symbols by adding current orientation information. We conducted a target orientation experiment using eye-tracking technology to examine whether symbol modification positively affected users’ orientating performance in virtual subway station scenes on desktop. The results indicated that participants in the modified symbol group achieved a higher accuracy within a shorter time in orientation tasks. We also found that modified symbols significantly reduced users’ visual reliance on environmental information. Another experiment, in order to further investigate the role of YAH symbols in maps of different complexity, indicated that our modified symbol achieved obvious improvements regardless of map complexity. These findings revealed that the modified symbols indeed improved the convenience of orientation and the overall usability of indoor layout maps.
室内布局图包含了建筑内部空间的信息。用户经常利用地图上的You-Are-Here (YAH)符号,首先确定自己当前的位置和方向,从而找到目标位置的方向。通常看到的圆形符号只表示用户的位置,这使得完成定位过程变得困难。基于对齐效应理论,我们通过添加当前方向信息来修改符号。我们使用眼动追踪技术进行了目标定向实验,以检验在桌面虚拟地铁站场景中,符号修改是否对用户的定向表现有积极影响。结果表明,修改符号组的参与者在较短的时间内获得了更高的定向任务准确性。我们还发现,修改后的符号显著降低了用户对环境信息的视觉依赖。在另一项实验中,为了进一步研究YAH符号在不同复杂程度的地图中的作用,我们的改进符号在不考虑地图复杂程度的情况下都取得了明显的改进。这些发现表明,修改后的符号确实提高了方向的便利性和室内布局地图的整体可用性。

ABSTRACT Discrete Global Grid Systems (DGGS) provide a multi-resolution discrete representation of the Earth and are preferable for the organization, integration, and analysis of large and multi-source geospatial datasets. Generating grids for the area of interest is usually the premise and basis for DGGS applications. Owing to incongruent hierarchies that restrict the multi-resolution applications of hexagonal DGGS, current grid generation of hexagonal DGGS for local areas mainly depends on inefficient single-resolution traversal methods by judging the spatial relationship between each cell and the area. This study designs a fast generation algorithm for local parts of hexagonal DGGS based on the hierarchical properties of DGGS. A partition structure at intervals of multiple levels is first designed to ensure the coverage relevance between parent and children cells of different levels. Based on this structure, the algorithm begins with coarser resolution grids and recursively decomposes them into the target resolution, with multiple decomposition patterns used and a unique condition proposed to make the generated grids without gaps or overlaps. Efficient integer coordinate operations are used to generate the vast majority of cells. Experimental results show that the proposed algorithm achieves a significant improvement in efficiency. In the aperture 4 hexagonal DGGS, the efficiency ratio of the proposed and traversal algorithms increases from six times in level 14 to approximately 339 times in level 18. This study provides a solid foundation for subsequent data quantization and multi-resolution applications in hexagonal DGGS and has broad prospects.
离散全球网格系统(DGGS)提供了地球的多分辨率离散表示,更适合组织、集成和分析大型多源地理空间数据集。为感兴趣的区域生成网格通常是DGGS应用的前提和基础。目前六边形DGGS局部网格的生成主要依赖于效率低下的单分辨率遍历方法,主要是通过判断每个单元与区域之间的空间关系来实现。基于六边形DGGS的层次性,设计了一种局部部分快速生成算法。首先设计了多层间隔的分区结构,以保证不同层次的父细胞和子细胞之间的覆盖相关性。基于该结构,该算法从粗分辨率网格开始,递归分解为目标分辨率网格,使用多种分解模式,并提出一个唯一条件,使生成的网格无缝隙和重叠。高效的整数坐标操作用于生成绝大多数单元格。实验结果表明,该算法的效率得到了显著提高。在孔径4的六边形DGGS中,所提算法和遍历算法的效率比从第14级的6倍提高到第18级的约339倍。该研究为六边形DGGS的后续数据量化和多分辨率应用提供了坚实的基础,具有广阔的前景。

ABSTRACT Humans increasingly rely on GPS-enabled mobile maps to navigate novel environments. However, this reliance can negatively affect spatial learning, which can be detrimental even for expert navigators such as search and rescue personnel. Landmark visualization has been shown to improve spatial learning in general populations by facilitating object identification between the map and the environment. How landmark visualization supports expert users’ spatial learning during map-assisted navigation is still an open research question. We thus conducted a real-world study with wayfinding experts in an unknown residential neighborhood. We aimed to assess how two different landmark visualization styles (abstract 2D vs. realistic 3D buildings) would affect experts’ spatial learning in a map-assisted navigation task during an emergency scenario. Using a between-subjects design, we asked Swiss military personnel to follow a given route using a mobile map, and to identify five task-relevant landmarks along the route. We recorded experts’ gaze behavior while navigating and examined their spatial learning after the navigation task. We found that experts’ spatial learning improved when they focused their visual attention on the environment, but the direction of attention between the map and the environment was not affected by the landmark visualization style. Further, there was no difference in spatial learning between the 2D and 3D groups. Contrary to previous research with general populations, this study suggests that the landmark visualization style does not enhance expert navigators’ navigation or spatial learning abilities, thus highlighting the need for population-specific mobile map design solutions.
摘要人类越来越依赖GPS移动地图来导航新环境。然而,这种依赖可能会对空间学习产生负面影响,即使对搜救人员等专业导航人员来说也是有害的。地标可视化已被证明可以通过促进地图和环境之间的物体识别来改善普通人群的空间学习。在地图辅助导航过程中,地标可视化如何支持专家用户的空间学习仍然是一个悬而未决的研究问题。因此,我们与寻路专家在一个未知的居民区进行了一项现实世界的研究。我们旨在评估两种不同的地标可视化风格(抽象的2D建筑和逼真的3D建筑)在紧急情况下如何影响专家在地图辅助导航任务中的空间学习。使用科目间设计,我们要求瑞士军事人员使用移动地图遵循给定的路线,并确定路线上五个与任务相关的地标。我们记录了专家在导航时的凝视行为,并检查了他们在导航任务后的空间学习情况。我们发现,当专家将视觉注意力集中在环境上时,他们的空间学习能力有所提高,但地图和环境之间的注意力方向不受地标可视化风格的影响。此外,2D组和3D组在空间学习方面没有差异。与之前对普通人群的研究相反,这项研究表明,地标可视化风格并不能提高专业导航员的导航或空间学习能力,从而突出了对特定人群移动地图设计解决方案的需求。
