 Searching tool: This tool enables an operator to search
for objective measured data and recorded video images
and conversations.
 Replaying tool: This tool replays selected video images
and conversations.

4.4.1. Monitoring tool
A supervisor selects an operator and patient pair from
the coaching list shown in Figure 14 and clicks the join
button. A supervisor can see which operator is coaching
which patient by looking at this list. A voice path is
established between a supervisor and an operator with the
sequence flow shown in Figure 5. After a supervisor logs in,
Figure 11. Stand-up and sit-down training
the monitoring tool on the supervisor-PC obtains a peer ID
from the SkyWay server and sends it to the video call center
server. The video call center server sends the
operatorPeerID to the supervisor-PC in accordance with the
request from the supervisor-PC. After that, the monitoring
tool on the supervisor-PC establishes a voice path to an
operator-PC in cooperation with the SkyWay server and
displays the same screen that an operator is viewing (e.g.
Figure 12 (b)).

4.4.2. Recording tool
Video images and conversation of an operator coaching
a patient are automatically stored in the video call center
server as archived files. Directory paths to all files are
managed by the database management system. The structure
of this database management system is described in the next
sub-section.

4.4.3. Searching tool
Since measurements of the patient, video images on an
operator’s display, and conversations are large data, they are
stored as files. Moreover, directory paths to all files are

data and archived data are featured by the following keys:
