Gaze awareness for video-conferencing: a software approach

S. Seitz, T. Kang, C.L. Zitnick, K. Toyama, J. Gemmell
2000 IEEE Multimedia  
The typical videoconferencing interface doesn't provide gaze awareness or give participants a sense of spatial relationships. Figure A.  ...  Existing systems restore gaze awareness only by using special and typically expensive hardware. We developed a software-based approach to videoconferencing gaze awareness.  ...  We intend to publicly release our software with a replaceable vision module, which will let vision research groups try their own approaches using our system.  ...

Gaze correction for home video conferencing

Claudia Kuster, Tiberiu Popa, Jean-Charles Bazin, Craig Gotsman, Markus Gross
2012 ACM Transactions on Graphics  
While this problem has been partially solved for high-end expensive video conferencing systems, it has not been convincingly solved for consumer-level setups.  ...  Our method is suitable for mainstream home video conferencing: it uses inexpensive consumer hardware, achieves real-time performance and requires just a simple and short setup.  ...  Thanks to Michal Nir, Saar Gross and Omri Azencot of Technion for developing the Skype plugin.  ...

Immersive 3D video conferencing: challenges, concepts, and implementation

Peter Eisert, Touradj Ebrahimi, Thomas Sikora
2003 Visual Communications and Image Processing 2003  
In this paper, a next generation 3-D video conferencing system is presented that provides immersive telepresence and natural representation of all participants in a shared virtual meeting space.  ...  Beside low bit-rates, the model-based approach enables new possibilities for image enhancements like digital make-up, digital dressing, or modification of scene lighting.  ...  First with the introduction of digital computers, cheap and powerful hardware and software devices have been developed and, today, video conferencing is rapidly advancing.  ...

A QoE study of different stream and layout configurations in video conferencing under limited network conditions

Simon N. B. Gunkel, Marwin Schmitt, Pablo Cesar
2015 2015 Seventh International Workshop on Quality of Multimedia Experience (QoMEX)  
However, video conferencing with two people (one-to-one) and within a group (multi-party) is different.  ...  One particular problem of QoE research in video conferencing is, that most research in the past concentrated on one-to-one video conferencing or simply video consumption.  ...  Thanks goes to all partners of the Vconect project for their valuable input. Special thanks go to Yaroslav Kryvyi for his technical support.  ...

HoloPort - A Device for Simultaneous Video and Data Conferencing Featuring Gaze Awareness

M. Kuechler, A. Kunz
IEEE Virtual Reality Conference (VR 2006)  
In this paper, a system setup dubbed HoloPort is presented, which enables intuitive point-to-point video conferencing between two small groups.  ...  The device features gaze awareness between local and remote conferees during video and data conferences, and pen-based on-screen interaction.  ...  Again, today's video conferencing systems with cameras placed on the side of the display or screen do not allow gaze awareness.  ...

Mitigating problems in video-mediated group discussions

Marwin Schmitt, Simon Gunkel, Pablo Cesar, Dick Bulterman
2014 Proceedings of the 2014 workshop on Understanding and Modeling Multiparty, Multimodal Interactions - UM3I '14  
Users further face a lack or distortion of non-verbal cues like gaze awareness.  ...  Further, we provide an analysis of the suitability of normal webcam data for such cue recognition. Based on our observations, we suggest strategies that can be implemented to alleviate the problems.  ...  In a standard video-conferencing setup mutual gaze is not possible. However this gaze-awareness is crucial for several turn-prediction models [8] .  ...
