How does map use differ in virtual reality and desktop-based environments?

ABSTRACT: Maps based on virtual reality (VR) are evolving and are being increasingly used in the fifield of geography. However, the advantages of VR based on the map use processes of users over desktop-based environments (DEs) are not fully understood. In this study, an experiment was conducted in which 120 participants performed map use tasks using maps and globes in VR and DE. The participants’ eye movements and questionnaires were collected to compare the map use performance di erences. We analyzed the general metrics, information searching and processing metrics of participants (e.g. response time, RT; average fifixation duration, AFD; average saccade duration, ASD; saccade frequency, SF, etc.) using maps and globes in di erent environments. We found that the participants using VR processed information more effiffifficiently (AFDDE = 233.34 ms, AFDVR = 173.09 ms), and the participants using DE had both a signifificantly shorter response time (RTDE = 88.68 s, RTVR = 124.05 s) and a shorter visual search time (ASDDE = 60.78 ms, ASDVR = 112.13 ms; SFDE = 6.30, SFVR = 2.07). We also found similarities in accuracy, satisfaction and readability. These results are helpful for designing VR maps that can adapt to human cognition and reflflect the advantages of VR.

Assessing Similarities and Differences between Males and Females in Visual Behaviors in Spatial Orientation Tasks

Abstract: Spatial orientation is an important task in human wayfinding. Existing research indicates sex‐related similarities and differences in performance and strategies when executing spatial orientation behaviors, but few studies have investigated the similarities and differences in visual behaviors between males and females. To address this research gap, we explored visual behavior similarities and differences between males and females using an eye‐tracking method. We recruited 40 participants to perform spatial orientation tasks in a desktop environment and recorded their eye‐tracking data during these tasks. The results indicate that there are no significant differences between sexes in efficiency and accuracy of spatial orientation. In terms of visual behaviors, we found that males fixated significantly longer than females on roads. Males and females had similar fixation counts in building, signpost, map, and other objects. Males and females performed similarly in fixation duration for all five classes. Moreover, fixation duration was well fitted to an exponential function for both males and females. The base of the exponential function fitted by males’ fixation duration was significantly lower than that of females, and the coefficient difference of exponential function was not found. Females were more effective in switching from maps to signposts, but differences of switches from map to other classes were not found. The newfound similarities and differences between males and females in visual behavior may aid in the design of better human centered outdoor navigation applications.

Differences in the Gaze Behaviours of Pedestrians Navigating between Regular and Irregular Road Patterns

Abstract:While a road pattern influences wayfinding and navigation, its influence on the gaze behaviours of navigating pedestrians is not well documented. In this study, we compared gaze behaviour differences between regular and irregular road patterns using eye-tracking technology. Twenty-one participants performed orientation (ORI) and shortest route selection (SRS) tasks with both road patterns. We used accuracy of answers and response time to estimate overall performance and time to first fixation duration, average fixation duration, fixation count and fixation duration to estimate gaze behaviour. The results showed that participants performed better with better accuracy of answers using irregular road patterns. For both tasks and both road patterns, the Label areas of interest (AOIs) (including shops and signs) received quicker or greater attention. The road patterns influenced gaze behaviour for both Road AOIs and Label AOIs but exhibited a greater influence on Road AOIs in both tasks. In summary, for orientation and route selection, users are more likely to rely on labels, and roads with irregular patterns are important. These findings may serve as the anchor point for determining how people’s gaze behaviours differ depending on road pattern and indicate that labels and unique road patterns should be highlighted for better wayfinding and navigation.

Comparing the roles of landmark visual salience and semantic salience in visual guidance during indoor wayfinding

 

 

Abstract:Landmark visual salience (characterized by features that contrast with their surroundings and visual peculiarities) and semantic salience (characterized by features with unusual or important meaning and content in the environment) are two important factors that affect an individual’s visual attention during wayfinding. However, empirical evidence regarding which factor dominates visual guidance during indoor wayfinding is rare, especially in real-world environments. In this study, we assumed that semantic salience dominates the guidance of visual attention, which means that semantic salience will correlate with participants’ fixations more significantly than visual salience. Notably, in previous studies, semantic salience was shown to guide visual attention in static images or familiar scenes in a laboratory environment. To validate this assumption, first, we collected the eyemovement data of 22 participants as they found their way through a building. We then computed the landmark visual and semantic salience using computer vision models and questionnaires, respectively. Finally, we conducted correlation tests to verify our assumption. The results failed to validate our assumption and show that the role of salience in visual guidance in a real-world wayfinding process is different from the role of salience in perceiving static images or scenes in a laboratory. Visual salience dominates visual attention during indoor wayfinding, but the roles of salience in visual guidance are mixed across different landmark classes and tasks. The results provide new evidence for understanding how pedestrians visually interpret landmark information during real-world indoor wayfinding.

北京市甲型H1N1流感对气象因子的时空响应

摘要:

为研究北京市甲型H1N1流感对气象因子的时空响应规律,本文结合地理探测器及空间自相关分析方法,分析北京市甲型H1N1流感的时空分布情况,基于地理加权回归(GWR)模型,建立北京市甲型H1N1流感与平均风速、降雨量、平均湿度以及平均温度之间的回归模型。结果表明,降雨量对流感传播的影响不显著,平均风速与流感的传播主要呈现正相关,平均相对湿度与平均温度与流感的传播主要呈现负相关,其中,平均相对湿度的影响更为复杂。时间上,在流感感染人数快速上升的阶段,各气象因子的影响程度较为显著,而在流感传播速度减慢的阶段,气象因子的影响减弱;空间上,各气象要素对流感传播的影响在北京市4大功能分区上存在空间分异性,这与地区地形、风带、局地气候等因素有关。

Real-time forecasting of hand-foot-and-mouth disease outbreaks using the integrating compartment model and assimilation filtering

Abstract: Hand-foot-and-mouth disease (HFMD) is a highly contagious viral infection, and real-time predicting of HFMD outbreaks will facilitate the timely implementation of appropriate control measures. By integrating a susceptible-exposed-infectious-recovered (SEIR) model and an ensemble Kalman filter (EnKF) assimilation method, we developed an integrated compartment model and assimilation filtering forecast model for real-time forecasting of HFMD. When applied to HFMD outbreak data collected for 2008–11 in Beijing, China, our model successfully predicted the peak week of an outbreak three weeks before the actual arrival of the peak, with a predicted maximum infection rate of 85% or greater than the observed rate. Moreover, dominant virus types enterovirus 71 (EV-71) and coxsackievirus A16 (CV-A16) may account for the different patterns of HFMD transmission and recovery observed. The results of this study can be used to inform agencies responsible for public health management of tailored strategies for disease control efforts during HFMD outbreak seasons.

Influence of scale on cognition of spatial differentiation regularities of population maps

Abstract: While population maps are important tools for people to perceive the regularities of population distribution, different scales of population maps cause map readers’ cognitive difference in the regularities of spatial distribution of population. In this paper, eye movement parameters such as number of fixations, fixation duration and number of correct answers were selected in the population map cognitive experiment by eye movement tracking to test the significance of the difference, and the results were analyzed from the perspective of spatial differentiation regularities. By exploring the influence of different scales including province and county (city) on map readers’ cognition of the distribution regularities of population, it is concluded that different scales of population maps have a significant impact on readers’ perception based on the significant difference analysis. When perceiving the characteristics of spatial distribution of population and the population quantity, more details and information are provided by county (city)-scale population maps, which is beneficial to readers’ understanding of the spatial differentiation regularities of population, with less average number of fixations, shorter average fixation duration, more correct number of answers for each question and higher cognitive efficiency. The impact of scale on the cognition of the population spatial distribution and the population size was discussed. The acquired cognitive rules of the scale can be used in designing the demographic maps and shortening readers’ cognition time, which is convenient for readers to extract valid information from the demographic maps, thus to improve the map usability. Besides, through the analysis of eye movement parameters like the fixations points, fixation time and number of correct answers, as well as the significance test, quantitative researches of the scale effects on the population distribution were carried out. The perspective drawing of the fixations hotspot can be used to visualize the cognitive spatial differentiation of the readers. And the results are no longer limited to the simple qualitative expression, which is of great significance for the use of different scales of demographic maps to express population distribution characteristics and regularities. In addition to adopting the hierarchical mapping method to draw the population maps, this thesis also has conducted experiments on the readers’ cognition of the spatial distribution regularities of population with different population density maps at different scales. Since it can reflect the population distribution more precisely and more visually, the results of this research may be further improved. And in the further work, the above population map needs further studying.

Using eye tracking to explore the impacts of geography courses on map-based spatial ability

Abstract: As part of geography education, geography courses play an important role in the development of spatial ability. However, how geography courses affect map-based spatial ability has not been well documented. In this study, we use an eye-tracking method to explore the impact of geography courses on map-based spatial ability. We recruited 55 undergraduates from Beijing Normal University (BNU) to attend the map-based spatial ability test before and after six-month geography courses arranged by the Faculty of Geographical Science, BNU. The results show that the participants’ map-based spatial ability significantly improved after taking the geography courses; specifically, accuracy increased by 22.3% and response time decreased by 14.7% after training. We analysed two types of eye-movement behaviour; in terms of processing measures, the fixation duration of the topographic map decreased by 18.4% and the fixation distribution was more concentrated after training, and in terms of matching measures, participants have more switch times per second for both photographed scenes and topographic maps. Switch times between options decreased by 48.2%, which is a notable decrease. These empirical results are helpful for the design of geography courses that improve map-based spatial ability.

User Experience Design for Mobile Cartography: Setting the Agenda

Beijing, China | July 11 & 12, 2019

Position Paper Deadline: 1 February 2019

Organizers

Purpose

The ICA Commissions on Cognition, LBS, VA, and Use are pleased to announce a joint workshop to outline a research agenda on Mobile Map UX. Since their first description in the cartographic literature (Zipf 2002, Reichenbacher 2001, 2004, Meng et al. 2005, Gartner et al. 2007), interactive mapping applications drawing on location-based services and mobile technologies have fundamentally transformed the way that people experience place. Accordingly, established tenets of cartography need to be reexamined and updated for the mobile platform. Further, new cartographic design strategies are needed for mobile maps to ensure a productive and satisfying user experience (UX).

Energy is surging around mobile in cartography and related fields (Huang et al. 2018), with extant research covering egocentric design (van Elzakker et al. 2009), mobile icon designs (Stevens et al. 2013), adaptive and responsive designs (Griffin et al. 2017), context-awareness (Huang 2016), situated learning (Roth et al. 2018), citizen science (Haklay 2013), and mobile design ethics (Wilson 2012, Ricker et al. 2014). Recent work also includes new educational materials on mobile cartography for classroom instruction (e.g., Muehlenhaus 2013; Huang & Gao 2018; Ricker & Roth 2018).
