6.3 Interaction• Rotation: Sets the rotation of the projection for x, y and z-axis.» Reset calibration: Resets the calibration data to standard values.» Calibrate: Calibrates the selected device.» Clear Config: Clears the complete configuration.Caution: All presets will be deleted!» Load Config: Loads configuration data from an xml-file.» Save Config: Saves configuration data to an xml-file.You can add a new tracking system by using the context menu in the devicelist. You have to enter its name (in the form trackername@computername)and then a connection to that VRPN server will be established. Then you canstart or stop the complete tracking process by clicking on the checkbox EnableTracking left of the device list.By using the last two columns in the device list you can rotate the coordinatesystem (Z-Up) and enable or disable the complete device (On).You can also calibratethe coordinate system as described above. A calibration needs one sensorthat describes the new coordinate systems, both its new origin and its new orientation.You can also edit the calibration matrix directly, but it is discouragedto use this method. When a device is created and selected, sensors can beadded to the device.Unfortunetaly, VRPN does not tell which sensors are connected, so you haveto enter them manually in the sensor list. You can also name each sensor foraccessing these via Python-scripts - the name has no other function. The followingsensor types are supported:» Buttons: Buttons are simple trigger buttons that have a unique identifier andtarget. Buttons do not need to be calibrated.» Analogs: Analogs are to be understood as analog pointing devices, such as ajoystick. Each movement axis must be mapped by adding an ”analog” sensor.» Dials: This type of sensor is capable of detecting states on rotary dials such asa volume control on a stereo system.187
