Ragnhild Eg | Westerdals Oslo School of Arts, Norway

Abstract: Computers make humans wait. When interacting with a computer system, no response is instant; every key stroke or mouse movement must be processed before the output is rendered and presented. If signals have to travel across a network, the waiting time, or latency, can extend into the perceptible and further into the detrimental. In addressing perceptible delays between motor inputs and visual outputs, different communities use different jargons. Yet they share a common interest in the perceptual and cognitive consequences of lagging responses. This talk will give an overview of current insights about temporal human-computer interactions, presenting findings from HCI, multimedia and psychological research.

ragnhild-profilBio: Ragnhild Eg is an associate professor at Westerdals Oslo School of Arts, Communication and Technology, where she combines her background and interest in perceptual psychology with digital marketing. She completed a PhD in psychology at the University of Oslo while working at Simula Research Laboratory. At Simula, she was part of a multi-disciplinary project that focused on the human perception of multimedia. Current projects relate to temporal human-computer interactions and the impact of delayed responses on performance. Ragnhilds research interests relate to the perceptual processing and integration of sensory information, particularly how the perceptual process is affected by the constraints imposed by technology.

Ketan Mayer-Patel | University of North Carolina at Chapel Hill, NC, USA

Abstract: There is a gap to be sparked between the fields of multimedia systems and computer vision. That gap is a vision-driven interface for rate controlled compressed video. Advances in vision have made real-world, real-time vision-based applications a reality. In doing so, there is now an imperative to integrate and negotiate systems-level tradeoffs with these vision algorithms as these real-world applications are realized. In this talk, I’ll motivate and propose a rate controlled interface extension for OpenCV to compressed video sources. I’ll discuss a possible compressed-domain implementation that is adaptable to a wide array of existing video standards. Finally, I’ll speculate about the potential impact of such an interface on future directions of research in vision-based multimedia systems.

Towards Understanding Truly Immersive Multimedia Experiences | Niall Murray | Athlone Institute of Technology, Ireland

Abstract: Immersive multimedia experiences have the possibility to engage users perceptually, cognitively and emotionally and there is significant interest due to their applicability across numerous application domains (film, entertainment, health, education, training, tourism, manufacturing). Important findings from psychological and neuroscience research, increased computational power, advances in sensor and display technologies are striving towards making truly immersive multimedia experiences a reality. In the context of various immersive, multimodal and mixed reality applications we have worked on; this talk will present an overview of our research towards understanding factors the make experiences immersive. It will focus on the user as the key stakeholder in the quality evaluation process. The talk will conclude by highlighting potential benefits, some trends and future research directions.

Geometric representations of 3D scenes | Geraldine Morin | University of Toulouse, France

Abstract: 3D content is spreading fast as a commonplace media. New technologies like 3D capture devices, head mounted display or 3D printers as well as numerous applications like e-commerce to virtual visits are fostering the use of 3D models. Starting from classical geometric representations limited to dedicated context (CAM-CAD, or game development), adapted models have to be devised in order to meet the constraints imposed by such different application contexts and technologies.

The goal of this talk is to give an overview of the different geometric representations (discrete or continuous, with and without topology) and their advantages and drawbacks. We introduce the existing adaptations of these models for creating, manipulating or sharing these models and their adaptation to specific multimedia applications. In particular, we review 3D compression, 3D model analysis for creation and edition based both on geometry and user interactions, and the different 3D characteristics for indexing 3D models.

In addition to her recognized work in compact and progressive representation and streaming for 3D plant models (best paper ACM MM 2008), Géraldine Morin worked on image based representations. More recently, she worked on identifying similarities in a 3D model and 3D applications indexing. In addition, she participated in work on the analysis of user interactions to adapt 3D content and their interactions.

Taiwan, officially called the Republic of China, is a delightful island.

Located off the southeastern coast of China, Taiwan is about the same size as Belgium and was named Formosa Island by Portuguese explorers in the 16th century due to its stunning natural beauty.

Chinese mainlanders started settling in Taiwan dating back to the 17th century, and the Japanese colonization of the island ended in 1945. Due to its historical mixture of influences, Taiwan has its own distinct culture.

Not many people know just how amazing the country is, which makes it one of the most underrated destinations in Asia.

Here are 23 reasons why you should visit Taiwan immediately:

1. Let's start with the food. Taiwanese people love to eat. The dishes people miss the most when they leave include beef noodle soup, soup dumplings from Din Tai Fung, and the uniquely Taiwanese oyster omelets.

2. If you've never had Taiwanese breakfast, you're missing out. Fuhang Doujiang in Taipei has a line out the door every morning and the wait for soy milk, egg crepes, and fried dough sticks is worth it.

3. Every major city has at least one night market — and all of them are worth visiting to try local specialty snacks and shop for souvenirs. Taipei alone has several night markets, including Shilin and Raohe. The city of Keelung's night market is arguably the country's largest and most renowned.
