Paper Title: Alternative inputs for games and AR/VR applications: deep headbanging on the web

Abstract: In multimedia research, scientific progress is often slowed downby high demands on hard- and software. However, hardware con-tinuously improves and today’s hardware got powerful enoughto meet the performance demands of complex 3D and deep learn-ing applications. With this demo, we demonstrate that utilizingdeep learning and 3D modeling is not a major barrier anymorewhen building prototypes for showcasing research projects. Ourweb-based game, called “HeadbangZ”, showcases a novel gesture-based input methodology realized through deeply learned poseestimation and user interaction in a 3D environment. Since gesture-based inputs increase the immersion in virtual environments, weassume this input methodology to be especially useful for AR/VRapplications and games. Furthermore, we demonstrate that rapidprototyping of applications using novel technologies, such as deeplearning, is even possible within 48 hours by developing a workingdemo within this time frame. Finally, we provide insights into whatwe learned during the development of HeadbangZ to encourageother researchers to make use of novel technologies. In referenceto Stephen Harper’s quote “Having hit a wall, the next logical stepis not to bang our heads against it.”, we hope that the presentationof HeadbangZ encourages researchers to bang their heads rhythmi-cally to rock music instead of angrily against a virtual wall createdby hard- and software limitations.

The paper “Semantics-aware Virtual Machine Image Management in IaaS Clouds” has been accepted for publication at 33rd IEEE International Parallel & Distributed Processing Symposium , IPDPS 2019 to be held at Rio de Janerio, Brazil (May 20-24 2019).

Abstract: Infrastructure-as-a-service (IaaS) Clouds concurrently accommodate diverse sets of user requests, requiring an efficient strategy for storing and retrieving virtual machine images (VMIs) at a large scale. The VMI storage management require dealing with multiple VMIs, typically in the magnitude of gigabytes, which entails VMI sprawl issues hindering the elastic resource management and provisioning. Nevertheless, existing techniques to facilitate VMI management overlook VMI semantics (i.e at the level of base image and software packages) with either restricted possibility to identify and extract reusable functionalities or with higher VMI publish and retrieval overheads. In this paper, we design, implement and evaluate Expelliarmus, a novel VMI management system that helps to minimize storage, publish and retrieval overheads. To achieve this goal, Expelliarmus incorporates three complementary features. First, it makes use of VMIs modelled as semantic graphs to expedite the similarity computation between multiple VMIs. Second, Expelliarmus provides a semantic aware VMI decomposition and base image selection to extract and store non-redundant base image and software packages. Third, Expelliarmus can also assemble VMIs based on the required software packages upon user request. We evaluate Expelliarmus through a representative set of synthetic Cloud VMIs on the real test-bed. Experimental results show that our semantic-centric approach is able to optimize repository size by 2.2-16 times compared to state-of-the-art systems (e.g. IBM’s Mirage and Hemera) with significant VMI publish and retrieval performance improvement.

Two Years of Game Studies and Engineering – Embracing the Importance of Videogames for the Digital Age

,

Wir feiern das zweijährige Bestehen des Masterprogramms Game Studies and Engineering an der Universität Klagenfurt mit einer besonderen Abendveranstaltung. Am 22. Jänner laden wir Sie um 18.30 Uhr in den Hörsaal 4 ein, um gemeinsam mit Ihnen einen Blick auf bisher Geleistetes und in die Zukunft der Game Studies und ihre Rolle für die technologischen und sozialen Herausforderungen der Menschheit für das digitale Zeitalter zu werfen.

Highlight des Abends ist der Vortrag „Project Discovery: Designing Games for a Better World“ von Attila Szantner. Als CEO und Mitbegründer von Massively Multiplayer Online Science (MMOS) ist er spezialisiert darauf Videospiele mit dem Themenfeld der Citizen Science zu vereinen. Für sein Projekt Discovery, das Spieler der Weltraumsimulation EVE Online menschliche Zellen analysieren lässt und damit unter anderem positiv zur Krebsforschung beitragen konnte, wurde er mit dem renommierten Lovie Award ausgezeichnet. Abgerundet wird Herrn Szantners Vortrag von kurzen Präsentationen der Mitbegründer des Masterprogramms Game Studies and Engineering und ihren an der Universität verfolgten Projekten und Perspektiven.

Als internationales Masterprogramm wird die Veranstaltung auf Englisch stattfinden. Wir freuen uns auf Ihr erscheinen.
