Introduction
As a researcher in the group of Distributed Interactive Systems at CWI, I am currently working on two European projects: 2-Immerse (https://2immerse.eu) and VRTogether (http://vrtogether.eu). The 2-Immerse project aims at developing new object-based TV production tools for multiscreen TV viewing experiences. For the VRTogether project, my current work focuses on developing appropriate Quality of Experience (QoE) metrics and evaluation methods for social VR experiences.

Social VR enables people to interact over distance with others in real-time. It allows remote people, typically represented as avatars, to communicate and perform activities together in a shared virtual environment, extending the capabilities of traditional social platforms like Facebook and Netflix. This paper explores the benefits and drawbacks p...

Virtual environments (VEs) can create collaborative and social spaces, which are increasingly important in the face of remote work and travel reduction. Recent advances, such as more open and widely available platforms, create new possibilities to observe and analyse interaction in VEs. Using a custom instrumented build of Mozilla Hubs to measure p...
Conference Paper

In this SIG, we aim at gathering researchers and practitioners to reflect on using XR technologies to support collabo-rative learning and co-creation, and to foster a joint force by connecting the Learning and Education community and the XR community at CHI. We witness a significant increase in CHI publications relating to these research areas: 292...
Conference Paper
Millions of photos are shared online daily, but the richness of interaction compared with face-to-face (F2F) sharing is still missing. While this may change with social Virtual Reality (socialVR), we still lack tools to measure such immersive and interactive experiences. In this paper, we investigate photo sharing experiences in immersive environme...
Conference Paper
While traditional live-broadcasting is typically comprised of a handful of well-defined workflows, these become insufficient when targeting multiple screens and interactive companion devices on the viewer side. In this case study, we describe the development of an end-to-end system enabling immersive and interactive experiences using an object-base...

Of the many crowd behavior models, very few have been used in assisting crowd management practice. This lack of usage is partly due to crowd management involving a diversity of situations that require competencies in observing, sense-making, anticipating and acting. Crowd research is similarly scattered across disciplines and needs integration to a...

In this article, we present examples of using designerly ways to explore “crowd” phenomenon in a cross-disciplinary project named EWiDS. The phrase ‘designerly ways’ refers to visual communication methods such as drawings and videos, which are widely acknowledged as effective approaches to cross- disciplinary collaboration. This study started with...

There are several approaches to detect emotions in a crowd, including surveillance cameras, human observers and sensors. One other approach to gather emotion data is self-reporting. A recent study sho...

We are only starting to understand how people behave when they are part of a crowd. This article presents a novel approach to the study and management of crowds. The approach comprises a device to be worn by individuals, an infrastructure to collect the information from the devices, a set of algorithms for recognizing crowd dynamics, and a set of f...

In view of the increasing crowds in public transportations and large events, crowd managers need tools to accurately estimate the psychology of crowds: an important aspect of this is crowd emotion. In this study, we explore the feasibility of obtaining a real-time, dynamic map of crowd emotions through self-reporting by crowd members. To this end,...
