Mutual Gaze Support in Videoconferencing Reviewed

Videoconferencing allows geographically dispersed parties to communicate by simultaneous audio and video transmissions. It is used in a variety of application scenarios with a wide range of coordination needs and efforts, such as private chat, discussion meetings, and negotiation tasks. In particular, in scenarios requiring certain levels of trust and judgement non-verbal communication, cues are highly important for effective communication. Mutual gaze support plays a central role in those high coordination need scenarios but generally lacks adequate technical support from videoconferencing systems. In this paper, we review technical concepts and implementations for mutual gaze support in videoconferencing, classify them, evaluate them according to a defined set of criteria, and give recommendations for future developments. Our review gives decision makers, researchers, and developers a tool to systematically apply and further develop videoconferencing systems in serious settings requiring mutual gaze. This should lead to well-informed decisions regarding the use and development of this technology and to a more widespread exploitation of the benefits of videoconferencing in general. For example, if videoconferencing systems supported high-quality mutual gaze in an easy-to-set-up and easy-to-use way, we could hold more effective and efficient recruitment interviews, court hearings, or contract negotiations

Establishing Phone Number Reputation Using a Contact Center Platform

Spam telephone calls decrease customer confidence in unknown callers; consequently, businesses can experience low call pickup rates. Some challenges with accurate caller identification are that a call from a legitimate business can be marked as spam, and that the name of the business that appears on the display need not be the actual owner of the number. This disclosure describes techniques to determine the accuracy of the caller ID and additional description such as business name or spam status reflected on a callee’s mobile device. An outbound test call is initiated from a contact center platform to a test mobile device. The session screen of the incoming call displayed on the test device is recorded and sent to a database. The recorded session screen is validated against pre-recorded data. The validation establishes the accuracy of the displayed caller ID and determines if the call is tagged as spam, enabling the business to take corrective action as necessary

Factors for the sense of presence within virtual architecture

Die Dissertation adressiert das Gebiet der Entwicklung von (räumlicher) Präsenz in computer-generierten virtuellen Umgebungen im speziellen und virtueller Architektur im besonderen. Der erste Teil motiviert die Arbeit, führt in die Terminologie ein und beschreibt die grundlegenden Prinzipien der virtuellen Realität (VR) und von VR-basierter Architektur. Der Schwerpunkt liegt auf sogenannten immersiven VR-Systemen. Der folgende Teil erarbeitet den theoretischen Hintergrund der Entwickling von Präsenz unter besonderer Beachtung philosophischer und kognitiver Ansätze. Ein eigenes Kapitel widmet sich der Klassifikation von Präsenz-Faktoren unter dem Gesichtspunkt der praktischen Gestaltung virtueller Architektur. Letztendlich werden verschiedene empirische Untersuchungen vorgestellt, die die entwickelten Ansaetze evaluieren und beschreiben. Die Ergebnisse werden im Kontext des architektonischen Gestaltens diskutiert.The dissertation addresses the domain of the development of the sense of presense within computer-generated virtual environments in general and within virtual architecture in particular. The first part provides motivation and terminology as well as the description of the basic principles of the generation of virtual worlds and virtual reality based architecture. The focus is set on so called immersive virtual reality systems. The following part offers a theoretical background on the sense of presence with special respect to philosophical and cognitive approaches. Considering practical aspects in developing virtual environments and architecture a classification framework for contributing factors is given in a seperate chapter. Finally several empirical investigations serve as a proof of the approaches developed and will be discussed in the context of architectural design
