Quantitative Methods for Visual Computing

We are living in a data society in which data is generated at amazing speed; individuals, companies, organizations, and governments are on the brink of being drawn into a massive deluge of data. The great challenge is to extract the relevant information from vast amounts of data and communicate it effectively.

Typical scenarios include decision and policy making for urban and environmental planning or understanding relationships and dependencies in complex networks, e.g., social networks or networks from the field of bioinformatics. These scenarios are not only of interest to specialized experts; in fact, there is a trend toward including the broad public, which requires the information to be presented in a reliable, faithful, and easy-to-understand fashion.

Visual computing can play a key role in extracting and presenting the relevant information.

In visual computing research the aspect of quantification is often neglected. The SFB-TRR 161 seeks to close this gap.

The long-term goal is to strengthen the research field by establishing the paradigm of quantitative science in visual computing.

Lecture | Visualization in Data Conversations

Held by:

Melanie Tory, Roux Institute of Northeastern University in Portland, Maine


Abstract:

Over the past several years I have begun to conceptualize visualization as a means to support data conversations. Conversation with data is the iterative interaction between people and data to ask and  answer questions (classic analysis work). In addition, we can recognize and highlight collaboration and  sharing practices involving data, or conversation through and around data, as critical data practices. In this talk, I'll introduce my framing of data conversations, with examples from various research and development projects from Tableau. I'll also introduce Viz@Roux, my new team at the Roux Institute of Northeastern University.


Biography:

Melanie e has more than 15 years of academic and industrial research experience, and joins the institute from Tableau Software, an interactive data visualization software company that was recently acquired by Salesforce for over $15B. Tory served as a Computer Science faculty member at the University of VictoTory is professor of the practice and director of data visualization research at the Roux Institute of Northeastern University in Portland, Maine. Shria and holds a PhD in Computer Science from Simon Fraser University. She is the Associate Editor of several visualization journals and serves on the steering committee of the IEEE VIS Conference.

Talk | Situated Analytics (Introduction to Workshop | Situated Analytics)

Held by:

Prof. Dieter Schmalstieg, Graz University of Technology, Austria

Abstract:

For the past few years, one can observe increased interest in combining visualization with new user interface technologies, such as virtual reality (VR) and augmented reality (AR). While immersive visualizations are usually implemented in VR, situated visualizations are grounded in the real world and, therefore, implemented in AR. With a mobile AR display, the user is freed from having to bring the data to the workplace and, instead, may go where the data belongs.
For situated visualization, referents are key. By extension, the same is true for situated analytics, i.e., analytic work supported by situated visualization. Situated analytics near referents is particularly relevant if referents actively provide data, such as via Internet of Things. Despite its promise to grant access to just the right data, anytime and anywhere, few works explore situated analytics for lengthy or complex tasks, such as visualization authoring or data exploration. In contrast to immersive analytics, which successfully capitalizes on providing unlimited virtual “space to think”, it appears that the benefits of situated analytics are harder to manifest.

Workshop | Introduction to R and Models for Psychophysics

Held by:

Dr. Alessandro Moscatelli, University of Rome and Dr. Priscilla Balestrucci, University of Ulm

Agenda:

09:30 am   Introduction to R and Tidyverse (Priscilla Balestrucci)
10:30 am   Break
10:45 am   Mixed Models in Psychophysics (Alessandro Moscatelli)

Abstract:
Psychophysical methods are widely used across different scientific communities to investigate the quantitative relation between a physical property of the world and its perceptual representation provided by the senses. This approach can provide evidence about basic sensory processes and assess the performance of an observer interacting with technological devices. Such methods can also help establish quantitative criteria for evaluating and designing novel technology.
The results of a psychophysical experiment are typically analyzed by fitting a psychometric function to each observer and then performing a second-level model for inferential statistics. Yet recent studies have shown that modelling data at the population level by means of Generalized Linear Mixed Models (GLMM) also has many advantages, specifically in terms of a better estimation of goodness of fit and of a higher statistical power.
In this workshop, we will demonstrate the use of the open-source statistical software R for processing and analyzing typical psychophysical data, using popular R libraries such as Tidyverse and Lme4 together with our package MixedPsy.

Talk | Quantification of Visual Attention in Mobile HCI

Held by:

Dr. Mihai Bâce, University of Stuttgart

Abstract:

Eye contact is a key measure of overt visual attention in mobile HCI as it enables understanding when, how often, or for how long users look at their devices. However, robustly detecting shifts of attention during everyday mobile interactions is challenging. Encouraged by recent advances in automatic eye contact detection, we present a method to accurately and robustly detect eye contact in images captured with the front-facing camera of common mobile devices. Based on our evaluations, we show how eye contact is the fundamental building block for calculating higher-level attention metrics and, as such, enables studying visual attention in the wild. We then present the Everyday Mobile Visual Attention (EMVA) dataset and quantitative evaluations of visual attention of mobile device users in-situ, i.e. while they use their devices during their everyday routine. Using our proposed method for eye contact detection, we quantify the highly dynamic nature of everyday visual attention allocation across users, mobile applications, and usage contexts. Finally, we discuss our findings that highlight the potential and inform the design of future mobile attentive user interfaces.

Biography:

Mihai Bâce is a post-doctoral researcher in the Perceptual User Interfaces group at the University of Stuttgart.

Keynote: Quantitative Methods for Perception-driven Visualization

Held by: Prof. Yunhai Wang, School of Computer Science and Technology, Shandong University

Abstract:

By providing visual representations of data, visualization can help people to carry out many data analysis tasks more effectively. Given a data set, however, there are often too many possible visualization techniques, with each technique having many parameters to be tuned. Here, the question arises is if it is possible to automatically design a visualization that is best suited to pursue a given task on given input data. With my lab, we attempt to quantitatively model human perception of different visualization types and developed a number of automated visualization techniques to achieve this goal for different data sets such as time-series, bivariate, high-dimensional, and set data. 

Biography:

Yunhai Wang is a Professor at Shandong University, China. He leads the Interactive Data Exploration System (IDEAS) Lab at Shandong University with the mission to enhance people's ability for understanding and communicating data. His current research interests include perceptual and mathematical foundations of visualization, domain specific languages for authoring interactive data visualization and data structures for big data visualization. He has published more than 50 papers in top venues for visualization and computer graphics, such as IEEE VIS, IEEE TVCG, ACM SIGGRAPH/SIGGRAPH Asia, ACM TOG and ACM CHI. He has collaborated with many international researchers especially with professors from Konstanz and Stuttgart. He is the main organizer of the yearly Sino-German Visualization Workshop (2017-2019 – stopped by Covid-19).

Capstone: Exploring the Design Space of Situated Analytics

Held by: Prof. DI Dr. Dieter Schmalstieg, TU Graz, Austria

Abstract:

Half a century after Ivan Sutherland's pioneering work on immersive interfaces, virtual reality (VR) and augmented reality (AR) are entering the commercial mainstream. Many of the roadblocks related to performance and usability are now resolved. The commoditization of these technologies makes it interesting to consider them not only for entertainment, but also for visualization and analytics work. New research on immersive analytics considers how the infinite virtual space can benefit not only the visualization of spatial data, but also of abstract data. New research on situated analytics considers how immersive interfaces can be physically grounded and blended with a user's perception of the real world. This talk will give an overview of recent developments in immersive and situated analytics and describe results of an ongoing research collaboration between the speaker's team in Graz and the University of Stuttgart.

Talk | Visualization of Multifield Data: Layouts, Features, and Systems

Held by:

Ass. Prof. Dr. Steffen Frey, University of Groningen, Netherlands

Abstract:

State-of-the art simulations and experiments in porous media research capture processes and phenomena in multiple high-resolution fields, each of which (partially) describes the state of an investigated system at a certain point in time. The richness of the obtained data provides an unprecedented opportunity to gain new insights, but also introduces various challenges for the analysis. This talk will focus on three complementary visualization approaches for making sense of multifield data: layouts  (the arrangement and aggregation of fields), features (the data representation used for analysis), and finally systems (the interactive visual exploration incorporating different components). All perspectives are presented via examples from prior work within SFB 1313 and beyond.

Biography:

Steffen Frey received his PhD degree in computer science from the University of Stuttgart in 2014 and worked as a postdoctoral researcher at the Visualization Research Center of the University of Stuttgart (VISUS). Since 2020, he is an assistant professor at the Bernoulli Institute at the University of Groningen, Netherlands. His research interests are in visualization methods for increasingly large quantities of scientific data.

Digitaler Girls' Day in Stuttgart und Konstanz | Bau dir deinen eigenen Bildschirmschoner

Der Girls' Day ist eine bundesweite Veranstaltung mit dem Ziel, das Interesse von Schülerinnen an Naturwissenschaften und Technik zu fördern. Dieses Jahr findet er am 22.04.2021 statt und wieder beteiligen sich unterschiedlichste Institutionen mit interessanten Aktionen rund ums Experimentieren und Forschen. Damit werden Einblicke in die Arbeit von Natur- und IngenieurwissenschaftlerInnen gegeben. Im Vordergrund der Veranstaltungen steht jedoch die Möglichkeit, selbst aktiv zu werden.

Auf Grund der Pandemie findet unser Angebot dieses Jahr digital statt.

Beim Girls Day 2021 bieten das Visualisierungsinstitut (VISUS), der Sonderforschungsbereich (SFB) 1313 und der transregionale Sonderforschungsbereich (SFB-TRR) 161 der Universität Stuttgart und der Universität Konstanz folgenden Workshop an:

Programmieren? Das kann ich auch! - Bau dir deinen eigenen Bildschirmschoner
(Klasse 7 - 10)

Willst Du eigene Programme schreiben, die genau das machen, was du willst? Wir geben Dir die nötige Starthilfe dafür. In unserem Workshop kannst Du Dir Deinen eigenen Bildschirmschoner programmieren. Soll er sehr farbenfroh aussehen? Möchtest du einen Text hinzufügen? Sollen sich die Muster bewegen? Bei uns kannst du dich gestalterisch austoben und dein persönliches Design direkt selbst umsetzen und auch später noch in aller Ruhe anpassen.

Während des Workshops wird es ein Coding-Quiz geben, bei dem Ihr Euer Wissen testen und am Ende einen Preis gewinnen könnt!

Programmier-Vorkenntnisse sind für unseren Coding-Kurs nicht zwingend erforderlich. Alle wichtigen Informationen erhaltet ihr im Workshop. Außerdem stehen euch sehr nette Helferinnen und Helfer zur Verfügung, die euch während des Codens „über die Schulter sehen“ und euch unterstützen. Natürlich könnt Ihr auch all Eure Fragen über das Informatikstudium bei uns loswerden und alles über das Leben und Arbeiten auf dem Campus erfahren.

Die Anmeldung erfolgt über www.girls-day.de

Einige Tage nach der Anmeldung erhaltet ihr eine Anmeldebestätigung per E-Mail und ein Einverständnisformular für online-Veranstaltungen per Videokonferenz (Webex). Bitte sorgt dafür, dass euer Postfach mindestens 1 MB Platz hat.

Wir freuen uns auf Euch!
