One of the substantial issues in ubiquitous computing is the automatic processing of information
from real world objects and enabling their interactions in the background. This scenario requires a
framework on which such information processing and object interaction can be supported. This
article presents our research progress in developing a framework based on the object-oriented
design approach and the use of a push web server. With the concept of object abstraction, an object
can hide its internal structure from the outside world, which can make the object secure. Moreover,
object interaction can be conducted via message exchanges, which makes the interface simple
and standardized and the heterogeneous objects can be easily handled as well. Instead of using
the traditional pull web server, a push web server, i.e., Comet, which runs on top of HTTP protocol is
used to exchange messages. To this, object interactions can be operated smoothly and
seamlessly in real time with shorter delay.
