Hello Alfred, Thanks very much for your reply. I have tried to implement a new function to realize hotplugging in MITK::NDITrackingDevice, but failed due to the tight cooperation between several related classes as you said. I will stop revising NDITrackingDevice and try the PLUS package for this feature.
For monitoring the connection state of sensors, there is indeed a flag provided in MITK, while I acctually expect a flag that can monitor the NDI port sate, i.e., the value of this flag is changed when a tool (sensor) is pluged or unpluged, according to your reply, this flag should not exit in current MITK::NDITrackingDevice, I think it is also the key to realize hotplugging in MITK. I will go on working on this problem, and let you know if it can work with PLUS. Thanks!
