The AIPA team will participate in the Lange Nacht der Wissenschaften [1] on May 10th 2014. We offer workshops on 3D video and video transmission services.

Detailed Program [2]

Between 24th and 26th March 2014, AIPA hosted the 7th general meeting of Qualinet. The network gathers European experts in Quality of Experience (QoE) and boosts research in this field. In particular, the focus it put on development of new methodologies for determining perceived quality according to new trends in multimedial communication. Over 70 researchers gathered in Berlin to present and discuss the topics related to video streaming, crowdsourcing, emotions and many others.

Alexander Raake [6] & Sebastian Möller co-organized the special session on Speech quality perception and assessment during the AIA-DAGA 2013 conference. More than 10 contributions were presented during lecture and poster sessions. AIA-DAGA 2013, the joint conference of Acoustical Society of Italy and German Acoustical Society, was held from 18th to 21st March 2013 in Merano, Italy.

Speech services - for communication between humans or between humans and machines - have mainly been evaluated following two paradigms: On the one hand, metrics of system performance have been developed to quantify the characteristics of the system and its underlying components; on the other hand, subjective evaluation has been carried out to analyze the quality perceived by actual users (Quality of Experience, QoE). However, automatic evaluation of speech technology is more convenient in order to save costly and time-consuming subjective tests, and will ultimately lead to better speech services.

The primary purpose of this special session is to discuss technological and perceptual metrics related to the quality of experiencing speech services. We ask: What conceptions of quality are currently in use, and how do they relate to each other? What information can be extracted from speech signals? What types of speech transmission degradations are covered by standardized prediction models like PESQ and the E-model? Which approaches can be taken to monitor speech quality? What parameters can be used for describing spoken dialogue system performance and user behavior in spoken-dialogue interactions? How can these parameters be related to system quality? Is it possible to simulate user behavior for this purpose?

About PQS 2010 (from the website):

The quality of systems which address human perception is difficult to describe. An engineering approach to quality includes the consideration of how a system is perceived by its users, and how the needs and expectations of the users develop. Thus, quality assessment and prediction have to take the relevant human perception and judgement factors into account.

The workshop is intended to provide an interdisciplinary exchange of ideas between both academic and industrial researchers working on different aspects of perceptual quality of systems. Papers are invited which refer to methodological aspects of quality and usability assessment and evaluation, the underlying perception and judgment processes, as well as to particular technologies, systems or services.

Third International Workshop on Perceptual Quality of Systems is a direct successor to the successful workshop series inaugurated in Herne in 2003, and in Berlin in 2006. We invite your papers, posters and demonstrations on these topics, and look forward to seeing you in Dresden in September 2010.

About QoMEX 2010 (from the website):

The second International Workshop on Quality of Multimedia Experience (QoMEX) will bring together leading professionals and scientists who are developing methods for evaluating multimedia quality and user experience.

Typically, multimedia processing algorithms are evaluated using objective metrics or through subjective testing in a controlled environment. However, perceived user experience is psychological in nature and changes in different environmental conditions and with different multimedia devices. Therefore, new techniques are needed to assess and enhance multimedia experience from the user perspective. QoMEX’10 is an international forum to gather experts from academia and industry to present the latest developments on evaluation of multimedia quality based on user experience.

QoMEX’10 features oral presentations, exhibits, panels and poster sessions in order to provide attendees with various channels to exchange and acquire information about the latest developments and future trends in the field of multimedia user experience.

Topics of interest include but are not limited to:

• User Experience Assessment and Enhancement: New metrics to define quality of user experience, interaction between auditory, visual, affective and other modalities and their impact on user experience, UI design, user experience rendering, user experience acquisition, human and multimedia device interaction, multimedia quality evaluation tools for generic and specific applications.
• Visual User Experience (Image/Video/Graphics): Objective quality metrics, subjective quality evaluation, psycho-visual modeling, quality-centered processing, compression and transmission, artifacts reduction, relationship between errors/noise/losses to human perception, display-specific processing, 3D Video, quality evaluation in HD and beyond, quality evaluation in HDR content, quality issues in streaming video.
• Auditory User Experience (Speech/Audio): Psycho-acoustic modeling, quality assessment of interactive speech applications, VoIP, modeling based on human auditory perception, intrusive/non-intrusive models for quality evaluation.
• QoE for virtual, augmented and mixed realites: 3D audio, 3D video and multimodal representation, immersiveness, embodied interaction, haptic interaction, other modalities.
• Link between QoS, QoE and Acceptance: Innovation management based on QoS and QoE, business models, value of QoE, relationship between QoE and price.
• Psychological and sociological dimension of QoE: Physiological and neurotechnological measurement techniques, modality concepts and modality interaction, interaction and communication, semantics, user groups.
• Standardization Activities in Multimedia Quality Evaluation: Subjective evaluation methods, benchmarking efforts, databases and multimedia content characteristics, testing conditions, new objective metrics and models for upcoming standards, terminology definitions.
Examples of applications include VoIP, Video conferences/Tele-presence/Video chats, Virtual/mixed reality for games, education, training, arts, etc.
