Key Issues

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

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.


  1. Virtual space getting increasingly popular.
  2. May lead to social problems, particularly with addiction.
  3. Need to devise ways to reconnect  virtual users back to real world.


  1. Devise interactive message wall to promote social interaction between real and virtual space.
  2. Incorporate sensors to detect user proximity and  status in virtual and real space.
  3. Study effectiveness of interaction.


Cross-cultural studies of collaborative workspace

  1. 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.


  1. Information overload.
  2. Information tends to have social and episodic reference.
  3. Manual organization, utilization & consumption of voluminous data.


  1. Tag information within social context.
  2. Incorporate localization metadata.
