Abstract: 
Urban environments generate a large amount of complex and heterogeneous data, which creates opportunities for all kinds of data analysis across domains such as accessibility, climate, real estate, and infrastructure. Interested in these analyses are a diverse range of stakeholders each bringing distinct expertise, analytical workflows, and priorities. However, among many others, urban planners, architects, environmental scientists, and public health experts employ different workflows while participating in a highly collaborative analytical setting. This reality results in gaps in contribution and communication, impacting the ability of such stakeholders to work together and the inclusion of important opinions and insights. Trying to solve some of those challenges, many urban analytics tools have been developed over the years. They offer powerful means to explore the complexity of data while accounting for the iterative nature of the process. However, these tools are often tailored to particular domains and are the product of disjointed collaborations between visualization and domain experts. That being said, the complexity of urban phenomena, combined with the fragmented nature of current urban visual analytics systems, limits the ability of researchers and practitioners to construct reproducible and adaptable workflows. Existing tools often require specialized technical expertise, treat domain experts primarily as end users, and lack mechanisms for integrating workflows across design, implementation, and evaluation. 
Aiming to tackle the complexity of urban data and the collaborative nature of urban analytics, while remedying for current gaps in urban visual analytics tools, this dissertation will propose an ecosystem of tools and theoretical frameworks that try to answer the following question: &ldquo;how to support accessible, flexible, extensible, reproducible, and scalable tools across domains and users?&rdquo;. Across this ecosystem of tools, there is a common thread of a meta approach. Meaning that the tools proposed enable a large spectrum of users to build urban visual analytics systems at different levels of expertise. This dissertation will present three solutions developed iteratively and a fourth ongoing work. They are a product of close cooperation with experts and practitioners who supported the evaluation through a series of real-life case studies. First, the Urban Toolkit (UTK) introduces a flexible grammar-powered visualization framework for urban data integration, showcasing an example library with public datasets from: Chicago Data Portal, OpenStreetMap, NYC Open Data, and Analyze Boston. Curio builds on UTK to add a collaborative, dataflow-driven approach, presenting three usage scenarios with public datasets from OpenStreetMap and Google Street View. Then, Urbanite extends the previous tools to propose a framework for human-AI collaboration, fostering alignment for a declarative construction of urban VA systems. Three usage scenarios are presented using public datasets from: OpenStreetMap, OpenTopography, Project Sidewalk, and Urban Pulse's paper. Finally, I present ongoing research that investigates challenges and opportunities in translating a domain problem into a VA system in an AI-assisted environment. The three tools bridge the gap between stakeholders by increasing accessibility to urban data analysis while making sure that solutions are extensible and scalable enough to be reused in different contexts, thus supporting an already existing diverse set of urban visual analytics workflows.

EVL&rsquo;s SAGE Research Among Top 10 Innovations from UIC

EVL graduate research assistant Landon Dyken under the supervision of Sidharth Kumar is recognized for the publication entitled &ldquo;Enabling Fast and Accurate Crowdsourced Annotation for Elevation-Aware Flood Extent Mapping&rdquo;.   Mapping the extent of flood events is an important aspect of disaster management.  In recent years, deep learning methods have evolved as an effective tool to label high-resolution imagery and provide necessary flood extent mappings quickly.  These methods, though, require large amounts of annotated training data to create models that are accurate and robust to new flooded imagery.  FloodTrace, a web-based application that enables effective crowdsourcing of flooded region annotation for machine learning applications, helps address these challenges.

Abstract: 
The Electronic Visualization Laboratory (EVL), established in 1973 at the University of Illinois at Chicago (UIC), specialized in interactive electronic displays
even before the advent of the frame buffer. By ingeniously combining digital and analog systems, EVL enabled real-time interactive computer graphics through the Graphics Symbiosis System (GRASS). This system was instrumental for animator Larry Cuba in creating the computer graphics for the original 1977 &ldquo;Star Wars&rdquo; film, which was done frame by frame on 35mm film), as well as contributing to lesser-known movies like &ldquo;UFO: Target Earth&rdquo; for which the special effects were captured on video. SpiralPTL is a work preserved in the Museum of Modern Art&rsquo;s video art collection. Throughout the decades, EVL advanced the technology of computer graphics but also deeply integrated art, science, and education researchers and teaching faculty. This collaboration led to the creation of an interdisciplinary MFA program in Electronic Visualization, bridging UIC&rsquo;s Engineering College with its School of Art and Design. EVL&rsquo;s later innovations include the development of numerous interactive stereoscopic and autostereoscopic systems, most notably the Cave Automatic Virtual Environment (CAVE). This paper will describe and analyze these technological advancements, discussing both their successes and their challenges in adoption by scientists, engineers, and artists. The narrative will reflect on how these technologies have shaped interdisciplinary collaboration and the evolution of electronic art and visualization techniques over the past fifty years.

Abstract: 
When interacting with large displays, virtual reality, or augmented reality, people often use mid-air gestures. During these touchless interactions, they may need to alternate between hands or use both hands simultaneously. Most individuals have a hand preference, and preferred and non-preferred hands in lateralized individuals perform differently due to cerebral hemispheric specialization. For example, in right-handed individuals, the right hand is typically better at sequential motor tasks - those requiring (sensory) feedback control - whereas the left hand is better at parallel processing or open-loop behavior. In this thesis, we examine how lateral asymmetry impacts user performance in touchless input. My research provides an empirical investigation to characterize touchless performance when using preferred, non-preferred, and both hands. It explores binding the related tasks sequentially and in parallel, as well as different phrase structures, considering how much muscular tension is involved. 
In this work, we compared preferred and non-preferred hand performance in simple and compound tasks, such as pointing and select-and-dragging, respectively. In right-handed individuals, we did not find any significant performance differences between their preferred and non-preferred hands in touchless pointing or dragging. However, between-hand performance differences were significant when using mouse and stylus input. 
Additionally, we studied how phrasing with both hands can support volumetric multi-selection in touchless input. We present an empirical comparison of mid-air multi-selection techniques spanning dominant and non-dominant hand actions. The symmetric-synchronous and high-tension asymmetric-asynchronous bimanual techniques were not significantly different in terms of efficiency, and accuracy for within-reach targets. Furthermore, there were no significant differences between low and high-tension asymmetric-asynchronous bimanual techniques. The symmetric-synchronous bimanual technique was most preferred by users. 
Lastly, we explored how different phrase structures in bimanual phrasing impact compound task performance, such as touchless multi-selection and manipulation (e.g., drag-and-drop). Our findings revealed that while accuracy remained consistent across different tension levels, higher tension led to faster completion times through continuous gesture engagement. Interestingly, participants preferred half-tension phrasing for its ergonomic balance, as it minimized fatigue without compromising efficiency. These empirical findings can inform the design of future bimanual and multimodal interaction techniques involving touchless input.
