PNNL-13501 - Pacific Northwest National Laboratory

Summary and Conclusions
In previous versions of HI-space, the communication
between the gesture recognition and the applied
application computers was through simulated mouse
signals. The HI-space computer generated the mouse
signals and the serial mouse port of the application
computer received them. The effort of this project
extended the communications capabilities of the HI-space
by allowing communications through socket connections
to a prototype geospatial visualization application.
Distributing objects from the HI-space server to remote
clients is very effective at passing a spatial context of
individuals working in the HI-space environment to an
observing client. At this stage in the implementation, two
types of objects are shared between server and client:
1) objects encapsulating information about pointers that
enter the space, and 2) objects that encapsulate the
information about physical objects placed in the space.
The strong sense of the remote collaborator’s spatial
context in relationship to the shared information space has
great promise for advancing the productivity of people
working together.
