Abstract: In an interactive communication system, one or more stations enter a scan mode to receive ID codes transmitted by wearable devices and transmit the ID codes to a server. The server receives the ID codes and transmits a command to one of the wearable devices via at least one of the stations. The one of the wearable devices receives the command via the at least one of the stations and transmits a feedback, in response to the command, to the server. The stations can detect signal strengths of the wearable devices. The server can determine a location of each of the wearable devices according to the ID codes and the signal strengths detected by the stations.

When the average pressure value is more than the preset pressure value, it is determined that whether the display panel is functioning. When the display panel is not functioning, data in the storage device is protected by encrypting the data.
