Bivariate Hue Blending – a Tool for Designing Bivariate Choropleth Color Schemes
Jonatan Hildén
This paper discusses the relevance of bivariate choropleth maps particularly of the sequential/sequential or diagonal focal model type, designed to be used for visualizing two correlated quantitative variables. It then describes an interactive prototype tool for designing color palettes to be used on this type of bivariate choropleth maps, based on rotating hue angles in the Hue Chroma Lightness color space.
A Web-based Prototype Dashboard for the Visualization of Spatiotemporal Trends of Respiratory Syncytial Virus
Jingyi Liang, Saturnino Luz, You Li and Harish Nair
The Coronavirus (COVID-19) pandemic has underscored the importance of visualization tools in healthcare for monitoring infectious diseases. Geographic Information Systems (GIS) facilitate data comprehension by employing visual representation and analysis to convey disease-related information in a clear and accessible manner. Its increasing utilization in public health has been instrumental in enhancing disease surveillance and response planning efforts. Respiratory Syncytial Virus (RSV) is a ubiquitous viral infection that is prevalent in both children and adults, and it is the most common pathogen identified in lower respiratory tract infections in infants. However, current RSV surveillance lacks an integrated visualization platform utilizing GIS techniques. This research aims to address this gap by developing a web-based prototype dashboard that visualizes and analyzes RSV prevalence trends. The prototype dashboard is meticulously designed to provide comprehensive information about RSV, emphasizing a user-centric approach and interactive features. By leveraging GIS and visualization techniques, this study can contribute to the advancement of RSV surveillance and enhance our understanding of the disease.
Visualizing Meta-Analysis Data using Zoomable Heatmaps
Nicola Cerioli, Federico Simeoni, Rupesh Vyas, Mary Pat Reeve and Masood Masoodian
Meta-analysis studies, which require crossing genome-wide associations between samples belonging to different biobanks, are a crucial practice in genetics. Despite this, the visualization of the results tends to present readability issues, due to defaulting to error-prone displays. In fact, despite its efficacy and consequent wide use in genome-wide association studies, the traditional Manhattan chart is visually optimized for comparing peaks within one distribution of data points but presents limits outside these use cases. In this paper, we present a novel approach to visualizing such data which utilizes zoomable heatmaps to foster more efficient visual browsing and comparison, as well as allowing users to expand areas of the visual chart and explore its components.
Heuristic Evaluation of a Publicly Accessible Geoprocessing Platform: Categories of Usability Issues
Bruna Santana Capeleti, Juliana Baptista dos Santos França and André Pimenta Freire
The engagement with geoprocessing data has witnessed a substantial and continuous growth. As a response to this expansion, diverse sectors have commenced presenting their information through publicly accessible platforms that cater to a wide range of user profiles, encompassing experts and non-experts alike. In light of this prevailing trend, the objective of this research is to conduct a heuristic evaluation of a publicly accessible application by the Brazilian government, with a particular focus on geoprocessing. The primary aim of this evaluation is to identify and categorize the issues encountered by specialists during the assessment process. Consequently, this study aims to perform a heuristic evaluation of a Brazilian government's public application that is openly accessible. The study’s findings will be used to indicate the various categories of issues encountered in the evaluations. This research constitutes a crucial component of a broader investigative effort that explores diverse approaches to identifying common categories of issues among various geospatial applications. Ultimately, the results derived from this heuristic evaluation, alongside the broader research, are expected to make significant contributions to the improvement of geospatial applications.
Comparing the Effects of Different Illustration Methods on the Functionality of a Tourist Map
Mikko Airikka and Masood Masoodian
Tourist maps come in various forms, with some focusing on helping their users to find their way, some aiming to depict special characteristics of a certain place, and others providing information about services and experiences. Many tourist maps use illustrations to help achieve these tasks. To find out what kind of illustration choices should be made to improve the functionality of tourist maps, different illustration methods need to be compared. This paper focuses on going through the background, methods and results of a user study conducted to compare three different illustration methods implemented on a particular tourist map. The study was conducted as an online survey, where the time spent answering multiple-choice questions regarding tasks based on the maps was tracked. To compare the effects of the different illustration methods, a grid system was overlaid on the maps, and referred to when asking questions. The answer data was analyzed to find out whether the differences in the results were statistically significant. Overall, the results suggest that different illustration methods do not affect the functionality to a statistically significant degree. However, in particular situations the methods may have a notable effect on the map user's ability to acquire information. In addition, in certain scenarios illustrations can be used to convey information more efficiently.
Designing an Experiential Media System: A Mobile Augmented Reality System for Yamily Situated Documentaries
Yi-Fan Chen
Mobile media users utilize their devices to document their everyday experiences at the location. Users often share those situated documentaries both online and offline within their network. Mobile augmented reality systems (MARS) also open opportunities for users to retrieve their situated documentaries at the location. The current design research aims to propose a mobile experiential media design, specifically a mobile augmented reality system, for users to retrieve their family situated documentaries when they are physically present at the location. "Your Notes, My Love" MARS is designed based on the family's need to share love, information, memories, and knowledge. It serves as a user-generated situated documentary MARS for everyday life. The main functions of the design include mapping experiences for the user, mapping experiences created by the user, and incorporating a family tree feature. Results from five user tests demonstrate that the mobile experiential design is interesting and well-received for family situated documentaries. Users appreciate the notes created by family members for them, which makes the experiences more personal and intimate. They also find the map view design helpful because it simplifies the process of adding or accessing family situated documentaries at specific locations. Users suggest adding a family tree function to map out intergenerational memories.
