“Design, Design, and Design Again”:

While heuristics are useful resources for designing the web’s information architecture (IA) from scratch, IA practitioners occasionally receive requests to redesign established products, and guidelines are also needed to address such “redesign” requests. Past studies on IA design tend to focus on prototyping and how iterations contribute to final products, but such iterations have more to do with how users interact with the prototype than with its IA per se.

Based on two case studies, we explored a redesigned workflow of IA, which contains five stages: 1) screening, 2) synergizing, 3) synchronizing, 4) IA development, and 5) evaluation and execution. Compared to designing an IA from scratch, a team who redesigns an IA may communicate with more stakeholders and consider the impact of internal politics. Our proposed IA redesign workflow helps web designers allocate resources and prioritize work when given redesign tasks.

SiteSCAN: Intuitive Exchange of Spatial Information in Mixed Reality

SiteSCAN is a system that provides an intuitive design solution for exchanging and exploring spatial information. Traditional methods often fail to accurately link information with the physical spaces they represent, leading to a disjointed user experience. SiteSCAN addresses this issue by employing advanced image retrieval and geolocation technologies, allowing users to directly anchor and access information within specific physical locations. In addition, it allows for user contribution, creating a dynamic, user-generated information network. With the help of SiteSCAN, users will experience an intuitive interaction with spatial information and be presented with the seamless integration of virtual and physical reality.

User Perception and Eye Movement on A Pandemic Data Visualization Dashboard

Utilizing a two-phase experiment, this study assessed user interactions with a COVID-19 dashboard. With 27 participants, we explored color arrangements’ effects on image-memory, search, and browsing tasks. We found that the participants expected to obtain both global pandemic trends and single region/date statuses to help them capture important information in the shortest possible time. They also allocated their attention differently to the dashboard’s content areas to match their individual visual movement and reading habits. Feedback suggested the dashboards used alarming yet non-panic-inducing primary colors. Surprisingly, in our second stage eye-tracking experiment, participants mainly focused on headings and text instead of charts and graphs, as expected. These insights offer valuable design guidance for future data visualization and disaster dashboards.

Factors Influencing Criminologists' Open Research Data Practices: Trust, Contract, and Value

This study investigated criminology researchers’ data management practices and identified factors influencing their data sharing and data reuse. Our findings unveiled three key factors that shaped their behaviors and attitudes toward data sharing: trust, contract, and value. Examining the researchers’ concerns of sharing and reusing research data, we sought crucial insights that would be beneficial in developing a criminological research data repository, which would further consolidate the data infrastructure in social science. Sharing and reusing data can advance scientific research and provide innovative possibilities for practices in criminology (e.g., new correctional methods, new crime prevention policies), while providing sustained and thriving energy to the field.
