Talk Invited Talks: Layered Weighted Blended Order-Independent Transparency and AR Carcassonne

05.05.2022 13:00
G30

Speaker(s): Fabian Friederichs, Jannis Malte Möller

First talk: Layered Weighted Blended Order-Independent Transparency
Speaker: Fabian Friederichs
Abstract:
The presented approach improves the accuracy of weighted blended order-independent transparency, while remaining efficient and easy to implement. The original algorithm is extended to a layer-based approach, where the content of each layer is blended independently before compositing them globally. Hereby, we achieve a partial ordering but avoid explicit sorting of all elements. To ensure smooth transitions across layers, we introduce a new weighting function. Additionally, we propose several optimizations and demonstrate the method’s effectiveness on various challenging scenes in terms of geometric- and depth complexity. We achieve an error reduction more than an order of magnitude on average compared to weighted blended order-independent transparency for our test scenes.
 
Second Talk: AR Carcassonne - Extending a social game through projection mapping and traditional image processing
Speaker: Jannis Malte Möller
Abstract: Projection Mapping offers the possibility to extend the real world with virtual content and to experience it together as a group. In contrast to head-mounted displays, projection mapping is much less invasive and thus the usage inhibition threshold is lower. In this talk, I discuss the exemplary implementation of an extension of the popular board game Carcassonne through projection mapping and the underlying technology considerations for robust recognition.

Talk Promotions-Vorvortrag: Computer graphics from a bio-signal perspective - Exploration of Autonomic Human Physiological Responses to Synthetic and Natural Imagery

JP Tauscher is presenting his dissertation pre-talk Computer graphics from a bio-signal perspective - Exploration of Autonomic Human Physiological Responses to Synthetic and Natural Imagery on Friday, July, 30. at 1pm.

The impact of graphics on our perception is usually measured by asking users to complete self-assessment questionnaires. These psycho-physical rating scales and questionnaires reflect a subjective opinion by conscious responses but may be (in)voluntarily biased and do usually not provide real-time feedback. Subjects may also have difficulties communicating their opinion because a rating scale may not reflect their intrinsic perception or may be biased by external factors such as mood, expectation, past experience or even problems of task definition and understanding.


In this thesis, we investigate how the human body reacts involuntarily to computer-generated as well as real-world image content. Here, we add a whole new range of modalities to our perception quantification apparatus to abstract from subjective ratings towards objective bodily measures. These include electroencephalography (EEG), eye tracking, galvanic skin response (GSR), and cardiac and respiratory data. We seek to explore the gap between what humans consciously see and what they implicitly perceive when consuming generated and natural content. We include different display technologies ranging from traditional monitors to virtual reality (VR) devices commonly used to present computer graphical content.


This thesis shows how the human brain and the autonomous nervous system react to visual stimuli and how these bio-signals can be reliably measured to analyse and quantify the immediate physiological reactions towards certain aspects of generated and natural graphical content. We advance the current frontiers in the context of perceptual graphics towards novel measurement and analysis methods for immediate and involuntary physiological reactions.
