Jurriaan van Rijswijk

(Games for Health Europe Foundation)

What if games become medicine.

Abstract:. Transformation is global. We shift towards a purpose economy. The central theme for the economies will be about the impact it has on peoples’ lives instead on how profitable they are. Since a mayor component of our economies is about lifestyle interventions what better instrument for behaviour change can we use than games? People are intrinsically motivated for it and games do change behaviour. Jurriaan shares the vision of using games in all sectors with proven cases, research and benchmarks.

Short Bio: Jurriaan van Rijswijk is founder and chairman of the Games for Health Europe Foundation. He is an entrepreneur and serious game designer for 24 years and won the ICT Personality of the Year Award in the Netherlands. He develops game strategies and designs behavior change interventions using clinically and scientifically-validated games – for which he has also won various awards. Games for Health Europe Foundation is the worldwide co-creation network for research, development and implementation of games within the health ecosystem.

(UC, Portugal)

Computer Vision for Computer-Aided Surgery

Abstract: Arthroscopy is a modality of orthopeadic surgery where instruments and endoscopic camera (the arthroscope) are inserted into the articular cavity through small incisions (the surgical ports). Arthroscopy is highly beneficial for the patient and healthcare system because it reduces trauma, risk of infection and recovery time. However, clinical execution is difficult to accomplish because of indirect visualization and limited manoeuvrability inside the joint, with novices having to undergo a long training period and experts making mistakes of clinical consequences. This is a scenario where surgical assistive technologies can have strong impact in improving clinical outcome and disseminating the benefits of minimally invasive surgery.

    This talk introduces Video-based Computer-Aided Arthroscopy (VCAA), which is the first effective concept for navigated arthroscopy. VCAA combines real-time video processing for accurate 3D measurements on the anatomy, with augmented reality for overlaying meaningful guidance information in images. We will discuss the cRoomenges in applying 3D computer vision to arthroscopic footage and the devised solutions that conducted to fully functional systems already tested in “ex-vivo” experiments. We will also see how video-based navigation can be extended to open orthopaedic surgery and overview on-going efforts in using deep-learning to accomplish surgical guidance without having to attach fiducial markers to anatomy.

Short Bio: Joao P. Barreto holds a Ph.D. degree from the University of Coimbra (UC). He was visiting scholar in INRIA Rhone-Alpes, Grenoble, France, and a postdoctoral researcher in the University of Pennsylvania, Philadelphia, before joining the UC as a Professor. Joao is an acknowledged expert in 3D Computer Vision, being the author of more than 80 peer-reviewed articles in the most prestigious journals and conferences. He is the recipient of several academic distinctions and awards, including the “Google Faculty Research Award”, served as Area Chair in ECCV’2018 and ICCV2019, and is currently Associate Editor in the journals “Computer Vision and Image Understanding”, “Image and Vision Computing” and “Journal of Mathematical Image and Vision.

      Joao is also an entrepreneur having co-founded Perceive3D SA (P3D) in 2014. P3D builds in advanced knowledge in computer vision to provide advanced systems for improving visualization and guiding the surgeon during minimally invasive orthopedic procedures. Joao has been the CEO of P3D since foundation being responsible for R&D, Business Development and Investor Relations. The company has raised so far 1M€ in private capital and more than 2M€ in R&D grants having been awarded with the prestigious SMEi Phase 2 from the EU commission. @

Filip Sadlo

(UH, Germany)

 Flows and Features in Higher Dimensions

Abstract: In this talk, we examine recent advances in the visualization of multidimensional and multivariate fields. One direction of research is the development of novel feature concepts to extract the essential structure of such data. Due to the intricacy and high dimensionality of the resulting features, as well as the spaces that contain them, a related field of research is concerned with their visual representation and interaction. We motivate and exemplify the utility of the techniques using problems from mathematics, physics, and Earth science, and discuss possible directions of future work.

Short Bio: Filip Sadlo received his master’s and PhD degrees in computer science from ETH Zurich. Since 2014, he is a full professor of computer science at Heidelberg University, Germany, and the head of the Visual Computing Group. His research interests include visualization, computer graphics, and computational photography, with a focus on features and flows, physics, and simulation. He served on numerous program committees in the field, and as a co-chair for several conferences. ​@

Handmade Pixels - Feeding High-Resolution and High-Framerate Displays

Abstract: In this talk we will present work on rendering approaches for high resolution and   high frame rate displays at IVC. Displays include projections, display walls and HMDs. We show that game engines can be used to facilitate application development for large tiled display walls. Further, we report on work using tracked projectors to create a variable-dpi display. This is extended by audio cues to represent the context of a detail view.

An upcoming problem in high-resolution realtime high-quality rendering is the sheer number of pixels that need to be updated with high frequency. We argue that ray tracing is suited to address this problem and present work on foveated ray tracing for HMDs. The latter can be combined with elaborate global illumination approaches which we report on in the last part of the talk.

Data Visualization to Immersive Analytics: What’s next?

Abstract: Data visualization has been around for decades since the first computer graphics applications. However, only in the mid-eighties, visualization was understood as a research and development field per se, motivated by the ever-growing computational resources applied to collect, process, and generate large volumes of scientific data. Then, the web provided another environment to produce and disseminate information in several forms. Researchers started to develop techniques to visualize this variety of information in different ways since the data made available represented abstract information. In the mid-nineties, analysis tools joined this scenario because only visualizing information was not enough for the needs of new applications. The term "visual analytics" was coined to denominate several techniques from information visualization, statistics, and machine learning, which aimed to help develop solutions for data analysis.  In the last few years, we witnessed the emerging field of "immersive analytics", where we find virtual and augmented reality techniques being used for data visualization, especially for analysis of big data. Immersive analytics combines new interaction and display technologies to support analytical reasoning and decision making, thus encompassing visualization techniques and multisensory input (and output).  In this talk, I will summarize the main aspects involved in immersive analytics, by tracing the path from data visualization to immersive analytics, discuss the pros and cons of adopting such techniques, and outline the research scenario in the field.

Crowds Behavior Analysis and Simulation

Abstract: In this presentation, I will talk about the work I have done in the Crowds area since 1996, focusing on security systems and digital entertainment. In particular, I have worked to answer some questions: What features should I include in a crowd simulator in order to provide realistic mass, group and individual behaviors? When a crowd becomes a collective structure where groups are not visible anymore and collective abstractions are possible? Some methods take into account video data extraction; others consider the information coming from psychology or sociology areas, including cultural and personality analysis. And finally, how should I compare crowds and evaluate their realism? All analyzed data can be used in entertainment or serious applications to improve the realism of simulated NPC behaviors.
