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.

Their publication documenting the &rsquo;adventure&rsquo; over the years of developing, demonstrating, and engaging audiences in an innovative theater experience is recognized as the &ldquo;Best Art Paper&rdquo; of the Conference. 
VINCI is the premier international forum for researchers and industrial practitioners to discuss the state of the art in visual communication theories, designs, and applications. Visual communication through graphical or sign languages has long been conducted among humans of different backgrounds or cultures and, in recent decades, between humans and machines. In today's digital world, visual information is typically encoded with various metaphors commonly used in daily life to facilitate rapid comprehension and easy analysis during the communication process. Visual information communication generally encompasses information visualization, graphical user interfaces, visual analytics, and visual languages. Visual information is increasingly used to facilitate human-human communication through the Internet and mobile devices.

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.

Assistant professor Hy Kim, director of UIC&rsquo;s Human-Centered Engineering Lab will present his research: 
Friday 10/25/24, 1pm 
EVL Continuum (Room 2068 Engineering Research Facility) 
Abstract: 
Augmented reality (AR) has the potential to fundamentally change the way we interact with information. Direct perception of computer-generated graphics atop physical reality can afford hands-free access to contextual information on the fly. However, as users must interact with not only information on the display but also environmental changes in the real world, the traditional User-Centered Design (UCD) approaches that focus on human-computer interaction, may not always adequately address the dynamic nature of human-environment interaction. This seminar will introduce, Ecological Interface Design (EID), a new approach to the design and evaluation of AR interfaces to complement UCD. EID is a framework for interface design that respects dynamic, environmental constraints imposed on users&rsquo; behavior. EID addresses two questions for interface design; what information should be displayed (the content and structure of information that represent the physical reality of the work environment), and how that information should be presented (the perceptual forms of interface elements compatible with human information processing). The talk will start with the theoretical background of EID and show how this approach can benefit AR user interface design and evaluation with an example of an AR head-up display for vehicle drivers.

EVL hosts Jorge Wagner as a guest speaker, presenting &ldquo;Designing and Evaluating HMD-Based Immersive Analytics Environments&rdquo;. 
Friday 10/18/24, 1pm 
EVL Continuum, Room 2068 (Engineering Research Facility) 
Abstract 
The potential of Immersive Analytics approaches to enhance how humans understand and interact with data has attracted the attention of visualization researchers for decades, as is well illustrated by the work done at the EVL. Quick technological advances in head-mounted displays over the last years led to devices such as Meta Quest 3 and Apple Vision Pro, bringing those techniques closer to widespread adoption. However, the design space for Immersive Analytics applications is vast, and it is crucial to understand the advantages and disadvantages of alternative designs. Over the last eight years, during the development of my Master&rsquo;s and PhD dissertations, I have studied the design of HMD-based environments for Immersive Analytics, investigating different data exploration metaphors, frames of reference, and modes of interaction. As a result, I have also proposed a series of ideas to reimagine existing visualization applications to take advantage of the benefits of immersion. In this talk, I will present an overview of my research work and my current ideas on this topic, with a deeper focus on my most recent paper, &ldquo;Reimagining TaxiVis,&rdquo; which I believe sets forth concepts that can be useful for other applications.
