Abstract

True immersion into a distant environment and efficient distributed collaboration require the ability to physically interact with remote objects and to literally get in touch with other people. Touching and manipulating objects remotely becomes possible if we augment traditional audiovisual communications by the haptic modality. Haptic communications is a relatively young field of research that has the potential to substantially improve human–human and human–machine interaction.

In this talk, we address perceptual coding of haptic information and the transmission of haptic data streams over resource-constrained and potentially lossy networks. In this context, we also briefly discuss the need for objective quality metrics for haptic communication. Throughout the talk, we stress the fact that haptic communications is not meant as a replacement of traditional audiovisual communications but rather as an additional dimension for telepresence that will allow us to advance in our quest for truly immersive communication.

QoE beyond Audio-Visual: Sensory Experience

Abstract: The past decade has witnessed a significant increase in research efforts around Quality of Experience (QoE) which is generally referred to as a human-centric paradigm for Quality of a Service (QoS). As it puts the end user in the center stage, it may have various dimensions and one dimension aims at going beyond audio-visual promising advanced user experience through sensory effects. The motivation behind this work is that the consumption of multimedia content may stimulate also senses other than vision or hearing, e.g., olfaction, mechanoreception, or thermoception that shall lead to an enhanced, unique user experience, in this context referred to as sensory experience. In particular, we developed and standardized – within ISO/MPEG as part of the MPEG-V standard – a representation format for sensory effects that are attached to traditional multimedia resources such as audio, video, and image contents. Sensory effects (e.g., wind, lighting, explosion, heat, cold, scent) are rendered on special devices (e.g., fans, ambient lights, motion chair, air condition) in synchronization with the traditional multimedia resources with the intention to increase the users’ Quality of Experience (QoE). In particular, this talk provides a comprehensive introduction into the concept of sensory experience, its assessment in terms of the QoE, and related standardization and implementation efforts. Finally, we will highlight open issues and research challenges including future work.

Keywords: Quality of Experience, Sensory Experience, Subjective Quality Assessment, MPEG-V

Komplexe Systeme

Abstract: Ein komplexes System besteht aus miteinander verbundenen Teilen. Das System als Ganzes zeigt eine oder mehrere emer- gente Eigenschaften, welche nicht einfach aus den Eigenschaf- ten der einzelnen Teile abgeleitet werden können.

Das heißt, ein komplexes System verwehrt sich der Vereinfa- chung. Komplexe Systeme sind in vielen Bereichen wie z.B. Phy- sik (Interaktion von Teilchen), Chemie (chem. Reaktionen), Sozio- logie (Interaktion zwischen Menschen), Ökonomie (Vernetzung in der Wirtschaft) und Ökologie (Nahrungsketten) bereits allgegen- wärtig.

Durch die zunehmende Vernetzung von Komponenten in der Technik wird Wissen zu komplexen Systemen auch für die Infor- matik und Informationstechnik zunehmend bedeutender. Dazu ist es notwendig, sich eine neue Art und Weise anzueignen, um Systeme zu betrachten.

Im Rahmen diese einführenden Vortrags soll diese Grundlage an Hand einiger einfache Beispiele vermittelt werden.

Keywords: Komplexe Systeme, Vernetzung, selbstorganisierende Systeme

Fastest: test case generation from Z specifications

Abstract:

Fastest is a tool that assist software engineers in generating test cases from Z specifications. It provides tool support for a method of model-based testing know as the Test Template Framework. The tool reads a Z specification written in LaTeX markup and waits for commands from the user. Users can apply testing tactics to partition the input space of Z operations thus creating testing trees. Later they can prune these trees to eliminate unsatisfiable test specifications. In a third step, a satisfiability algorithm can be run to find a test case for each leaf in a testing tree. Finally, it is possible to refine these test cases into programs to test the implementation of the Z specification. In this talk I will show how Fastest works on some toy examples and our current research efforts.

 

Bio:

Maximiliano Cristiá is professor of Software Engineering at Universidad Nacional de Rosario (Argentina) and head of the Software Engineering Group at CIFASIS (International Franco-Argentine Center for Information Sciences and Systems). His research interests include formal methods, particularly model-based testing, software architecture and tool development for the Software Engineer.

Abstract

This talk will present SPLAY, an integrated system that facilitates the design, deployment and testing of large-scale distributed applications. Unlike existing systems, SPLAY covers all aspects of the development and evaluation chain. It allows developers to express algorithms in a concise, simple language that highly resembles pseudo-code found in research papers. The execution environment has low overheads and footprint, and provides a comprehensive set of libraries for common distributed systems operations. SPLAY is freely available from http://www.splay-project.org/.
