Key Issues

  • Context-aware framework and architecture.
  • Autonomic distributed architecture.
  • Supporting heterogeneous devices and systems.
  • Scalability (architecture, context metadata, etc.).
  • Incorporating social & episodic relationships.
 Problems to be addressed
  • Location accuracy.
  • Location latency.
  • Building the virtual world.
  • Real-time communication channels between worlds.
  • Modular framework to build applications and services.

Embodied Media Interactions

Participatory 3D Virtual Worlds

  • 3D mirror world with Geo-tagged multimedia content.
  • Information sharing and community networks.
  • Explore mechanisms to promote connection and social interaction between users in virtual world and people in physical space.
  • Virtual space getting increasingly popular.
  • May lead to social problems, particularly with addiction.
  • Need to devise ways to reconnect  virtual users back to real world.
  • Devise interactive message wall to promote social interaction between real and virtual space.
  • Incorporate sensors to detect user proximity and  status in virtual and real space.
  • Study effectiveness of interaction.

Cross-cultural studies of collaborative workspace

  • Tightly coupled remote work spaces with effective tele-presence.

SEISMIC: Socially & Episodically Indexed Spaces for Media-Information Collaboration

  • Incorporate localization metadata.
  • Organize into social & episodic context  database suitable for convenient retrieval.

  • Investigate use of location-awareness for socially-based & episodic tagging of media-info to facilitate easy use.
  • Information overload.
  • Information tends to have social and episodic reference.
  • Manual organization, utilization & consumption of volumnous data.


  • Tag information within social context.
  • Incorporate localization metadata.
