A simulator for a selected target mission, which generates telemetry (TM) of the spacecraft status and reacts to telecommands (TC).
A server, which interfaces to the simulator via a standard network interface (X.25 or TCP/IP) as well as to client user stations via Ethernet, and which handles both the incoming TM, and outgoing TC.
Clients, which display both 2D and 3D data to the operations team, and which are connected to tracking and interaction devices.
The Hierarchical 3D Spacecraft Inspector HSI will display the VR world in a layered fashion.
Different layers of detail will fold open as the operator zooms in. The operator will be able to zoom into the model, rotate it and do other simple movements by simply moving a prop, which he will hold in his non-predominant hand. The operator will hold a pen-like device in his dominant hand. The device will allow him to simply point and click in full 3D at any part of the logical model.
Possible techniqes for visualization of telemetry data are:
Context-Sensitive Information Display CSI emerges from the symbiosis of 3D graphics and a complex information-loaded structure such as a computer representation of a spacecraft.
Acting like a filter, it is designated to allow the focus on important information by selecting only appropriate data without compromising the overall 3D structure.
It is also capable of linking relevant pieces of information together by exploiting their three-dimensional context.
The Personal Workspace Operating System PWOS governs the different parts of the user interface and manages interaction hardware components. The PWOS handles tracker data coming from the magnetic tracking subsystem, the sketch-pad driver and keeps track of actions of other input devices. The PWOS will be a hidden part of the software system underlying all operations dealing with input devices for interaction.
