The workshop goals were to answer the following questions:
- What are the users expectations? Could the requirements and equipement be different for different tasks?
- Feedback from users of their experience of the applications in various uses (eg medical teleconference, within vehicles, in the context of home networking, standardization bodies, education…).
- What are the benefits and challenges of 3D technologies for teleconferencing?
- What are the needs for standardization to increase the number and quality of implementations and tools?
- How to implement performance testing methodologies in the context of teleconferencing?
- Are the current tools (models for speech and video quality evaluation) sufficient to characterize communications in context of conference call? What improvements are needed?
- What will be the next generation of electronic tools? Virtual meeting rooms, telepresence systems?
- What are the requirements and quality criteria for video when added to speech communications?
- What are the minimum requirements for rooms characteristics used for teleconferences?
