Welcome to Co-Space

Co-Space is a storage and query processing engine for supporting cyber-physical World. The system is being designed to support cross-domain relationships between objects.

The project is funded by the MDA (Media Development Authority) of Singapore.

Project Overview

Traditionally, the physical space and the virtual space are disjoint and distinct. Users in each space operate within the scope of the space, i.e, they may communicate among themselves but do not cross the boundary to the other space. However, technological advances in ubiquitous computing, smart interfaces and new augmented realities have made it possible for these two spaces to co-exist within a single space, the co (existing) space.

In a co-space environment (or cyber-physical system), the physical space and the virtual space interact simultaneously in real-time. Locations and events in the physical world are captured through the use of large number of sensors and mobile devices, and may be materialized within a virtual world. Correspondingly, certain actions or events within the virtual domain can affect the physical world (e.g. shopping or product promotion and experiential computer gaming). Thus, on one hand, the physical space is virtually enhanced with information. On the other hand, the virtual space is continuously refreshed with real-time, real-world information.

    SoCLink is a special social networking platform for National University of Singapore's School of Computing, where you can: Log in using your NUSNET ID. Share your status, blogs, galleries and videos with friends. Call for and participate in activities. Create your own group and join in friends' groups while keeping outsiders away. Sell and buy stuff in our market. MarcoPolo is a Web 2.0 community system that allows users to label various kinds of resources with tags, and mark them to the map simply by labelling them with user-defined hierarchical geo-tags. The MarcoPolo system provides two effective interfaces for users to browse and search the resources: one is the keyword-based interface and the other is the map-based interface.
